  • What is Audience Segmentation ? The 5 Main Types & Examples

    16 novembre 2023, par Erin — Analytics Tips

    The days of mass marketing with the same message for millions are long gone. Today, savvy marketers instead focus on delivering the most relevant message to the right person at the right time.

    They do this at scale by segmenting their audiences based on various data points. This isn’t an easy process because there are many types of audience segmentation. If you take the wrong approach, you risk delivering irrelevant messages to your audience — or breaking their trust with poor data management.

    In this article, we’ll break down the most common types of audience segmentation, share examples highlighting their usefulness and cover how you can segment campaigns without breaking data regulations.

    What is audience segmentation ?

    Audience segmentation is when you divide your audience into multiple smaller specific audiences based on various factors. The goal is to deliver a more targeted marketing message or to glean unique insights from analytics.

    It can be as broad as dividing a marketing campaign by location or as specific as separating audiences by their interests, hobbies and behaviour.

    Illustration of basic audience segmentation

    Audience segmentation inherently makes a lot of sense. Consider this : an urban office worker and a rural farmer have vastly different needs. By targeting your marketing efforts towards agriculture workers in rural areas, you’re honing in on a group more likely to be interested in farm equipment. 

    Audience segmentation has existed since the beginning of marketing. Advertisers used to select magazines and placements based on who typically read them. They would run a golf club ad in a golf magazine, not in the national newspaper.

    How narrow you can make your audience segments by leveraging multiple data points has changed.

    Why audience segmentation matters

    In a survey by McKinsey, 71% of consumers said they expected personalisation, and 76% get frustrated when a vendor doesn’t deliver.

    Illustrated statistics that show the importance of personalisation

    These numbers reflect expectations from consumers who have actively engaged with a brand — created an account, signed up for an email list or purchased a product.

    They expect you to take that data and give them relevant product recommendations — like a shoe polishing kit if you bought nice leather loafers.

    If you don’t do any sort of audience segmentation, you’re likely to frustrate your customers with post-sale campaigns. If, for example, you just send the same follow-up email to all customers, you’d damage many relationships. Some might ask : “What ? Why would you think I need that ?” Then they’d promptly opt out of your email marketing campaigns.

    To avoid that, you need to segment your audience so you can deliver relevant content at all stages of the customer journey.

    5 key types of audience segmentation

    To help you deliver the right content to the right person or identify crucial insights in analytics, you can use five types of audience segmentation : demographic, behavioural, psychographic, technographic and transactional.

    Diagram of the main types of audience segmentation

    Demographic segmentation 

    Demographic segmentation is when you segment a larger audience based on demographic data points like location, age or other factors.

    The most basic demographic segmentation factor is location, which is easy to leverage in marketing efforts. For example, geographic segmentation can use IP addresses and separate marketing efforts by country. 

    But more advanced demographic data points are becoming increasingly sensitive to handle. Especially in Europe, GDPR makes advanced demographics a more tentative subject. Using age, education level and employment to target marketing campaigns is possible. But you need to navigate this terrain thoughtfully and responsibly, ensuring meticulous adherence to privacy regulations.

    Potential data points :

    • Location
    • Age
    • Marital status
    • Income
    • Employment 
    • Education

    Example of effective demographic segmentation :

    A clothing brand targeting diverse locations needs to account for the varying weather conditions. In colder regions, showcasing winter collections or insulated clothing might resonate more with the audience. Conversely, in warmer climates, promoting lightweight or summer attire could be more effective. 

    Here are two ads run by North Face on Facebook and Instagram to different audiences to highlight different collections :

    Each collection is featured differently and uses a different approach with its copy and even the media. With social media ads, targeting people based on advanced demographics is simple enough — you can just single out the factors when making your campaign. But if you don’t want to rely on these data-mining companies, that doesn’t mean you have no options for segmentation.

    Consider allowing people to self-select their interests or preferences by incorporating a short survey within your email sign-up form. This simple addition can enhance engagement, decrease bounce rates, and ultimately improve conversion rates, offering valuable insights into audience preferences.

    This is a great way to segment ethically and without the need of data-mining companies.

    Behavioural segmentation

    Behavioural segmentation segments audiences based on their interaction with your website or app.

    You use various data points to segment your target audience based on their actions.

    Potential data points :

    • Page visits
    • Referral source
    • Clicks
    • Downloads
    • Video plays
    • Goal completion (e.g., signing up for a newsletter or purchasing a product)

    Example of using behavioural segmentation to improve campaign efficiency :

    One effective method involves using a web analytics tool such as Matomo to uncover patterns. By segmenting actions like specific clicks and downloads, pinpoint valuable trends—identifying actions that significantly enhance visitor conversions. 

    Example of a segmented behavioral analysis in Matomo

    For instance, if a case study video substantially boosts conversion rates, elevate its prominence to capitalise on this success.

    Then, you can set up a conditional CTA within the video player. Make it pop up after the user has watched the entire video. Use a specific form and sign them up to a specific segment for each case study. This way, you know the prospect’s ideal use case without surveying them.

    This is an example of behavioural segmentation that doesn’t rely on third-party cookies.

    Psychographic segmentation

    Psychographic segmentation is when you segment audiences based on your interpretation of their personality or preferences.

    Potential data points :

    • Social media patterns
    • Follows
    • Hobbies
    • Interests

    Example of effective psychographic segmentation :

    Here, Adidas segments its audience based on whether they like cycling or rugby. It makes no sense to show a rugby ad to someone who’s into cycling and vice versa. But to rugby athletes, the ad is very relevant.

    If you want to avoid social platforms, you can use surveys about hobbies and interests to segment your target audience in an ethical way.

    Technographic segmentation

    Technographic segmentation is when you single out specific parts of your audience based on which hardware or software they use.

    Potential data points :

    • Type of device used
    • Device model or brand
    • Browser used

    Example of segmenting by device type to improve user experience :

    Upon noticing a considerable influx of tablet users accessing their platform, a leading news outlet decided to optimise their tablet browsing experience. They overhauled the website interface, focusing on smoother navigation and better readability for tablet users. These changes offered tablet users a seamless and enjoyable reading experience tailored precisely to their device.

    Transactional segmentation

    Transactional segmentation is when you use your customers’ purchase history to better target your marketing message to their needs.

    When consumers prefer personalisation, they typically mean based on their actual transactions, not their social media profiles.

    Potential data points :

    • Average order value
    • Product categories purchased within X months
    • X days since the last purchase of a consumable product

    Example of effective transactional segmentation :

    A pet supply store identifies a segment of customers consistently purchasing cat food but not other pet products. They create targeted email campaigns offering discounts or loyalty rewards specifically for cat-related items to encourage repeat purchases within this segment.

    If you want to improve customer loyalty and increase revenue, the last thing you should do is send generic marketing emails. Relevant product recommendations or coupons are the best way to use transactional segmentation.

    B2B-specific : Firmographic segmentation

    Beyond the five main segmentation types, B2B marketers often use “firmographic” factors when segmenting their campaigns. It’s a way to segment campaigns that go beyond the considerations of the individual.

    Potential data points :

    • Company size
    • Number of employees
    • Company industry
    • Geographic location (office)

    Example of effective firmographic segmentation :

    Companies of different sizes won’t need the same solution — so segmenting leads by company size is one of the most common and effective examples of B2B audience segmentation.

    The difference here is that B2B campaigns are often segmented through manual research. With an account-based marketing approach, you start by researching your potential customers. You then separate the target audience into smaller segments (or even a one-to-one campaign).

    Start segmenting and analysing your audience more deeply with Matomo

    Segmentation is a great place to start if you want to level up your marketing efforts. Modern consumers expect to get relevant content, and you must give it to them.

    But doing so in a privacy-sensitive way is not always easy. You need the right approach to segment your customer base without alienating them or breaking regulations.

    That’s where Matomo comes in. Matomo champions privacy compliance while offering comprehensive insights and segmentation capabilities. With robust privacy controls and cookieless configuration, it ensures GDPR and other regulations are met, empowering data-driven decisions without compromising user privacy.

  • How to Choose the Optimal Multi-Touch Attribution Model for Your Organisation

    13 mars 2023, par Erin — Analytics Tips

    If you struggle to connect the dots on your customer journeys, you are researching the correct solution. 

    Multi-channel attribution models allow you to better understand the users’ paths to conversion and identify key channels and marketing assets that assist them.

    That said, each attribution model has inherent limitations, which make the selection process even harder.

    This guide explains how to choose the optimal multi-touch attribution model. We cover the pros and cons of popular attribution models, main evaluation criteria and how-to instructions for model implementation. 

    Pros and Cons of Different Attribution Models 

    Types of Attribution Models

    First Interaction 

    First Interaction attribution model (also known as first touch) assigns full credit to the conversion to the first channel, which brought in a lead. However, it doesn’t report other interactions the visitor had before converting.

    Marketers, who are primarily focused on demand generation and user acquisition, find the first touch attribution model useful to evaluate and optimise top-of-the-funnel (ToFU). 

    Pros 

    • Reflects the start of the customer journey
    • Shows channels that bring in the best-qualified leads 
    • Helps track brand awareness campaigns

    Cons 

    • Ignores the impact of later interactions at the middle and bottom of the funnel 
    • Doesn’t provide a full picture of users’ decision-making process 

    Last Interaction 

    Last Interaction attribution model (also known as last touch) shifts the entire credit allocation to the last channel before conversion. But it doesn’t account for the contribution of all other channels. 

    If your focus is conversion optimization, the last-touch model helps you determine which channels, assets or campaigns seal the deal for the prospect. 

    Pros 

    • Reports bottom-of-the-funnel events
    • Requires minimal data and configurations 
    • Helps estimate cost-per-lead or cost-per-acquisition

    Cons 

    • No visibility into assisted conversions and prior visitor interactions 
    • Overemphasise the importance of the last channel (which can often be direct traffic) 

    Last Non-Direct Interaction 

    Last Non-Direct attribution excludes direct traffic from the calculation and assigns the full conversion credit to the preceding channel. For example, a paid ad will receive 100% of credit for conversion if a visitor goes directly to your website to buy a product. 

    Last Non-Direct attribution provides greater clarity into the bottom-of-the-funnel (BoFU). events. Yet, it still under-reports the role other channels played in conversion. 

    Pros 

    • Improved channel visibility, compared to Last-Touch 
    • Avoids over-valuing direct visits
    • Reports on lead-generation efforts

    Cons 

    • Doesn’t work for account-based marketing (ABM) 
    • Devalues the quality over quantity of leads 

    Linear Model

    Linear attribution model assigns equal credit for a conversion to all tracked touchpoints, regardless of their impact on the visitor’s decision to convert.

    It helps you understand the full conversion path. But this model doesn’t distinguish between the importance of lead generation activities versus nurturing touches.

    Pros 

    • Focuses on all touch points associated with a conversion 
    • Reflects more steps in the customer journey 
    • Helps analyse longer sales cycles

    Cons 

    • Doesn’t accurately reflect the varying roles of each touchpoint 
    • Can dilute the credit if too many touchpoints are involved 

    Time Decay Model 

    Time decay models assumes that the closer a touchpoint is to the conversion, the greater its influence. Pre-conversion touchpoints get the highest credit, while the first ones are ranked lower (5%-5%-10%-15%-25%-30%).

    This model better reflects real-life customer journeys. However, it devalues the impact of brand awareness and demand-generation campaigns. 

    Pros 

    • Helps track longer sales cycles and reports on each touchpoint involved 
    • Allows customising the half-life of decay to improve reporting 
    • Promotes conversion optimization at BoFu stages

    Cons 

    • Can prompt marketers to curtail ToFU spending, which would translate to fewer qualified leads at lower stages
    • Doesn’t reflect highly-influential events at earlier stages (e.g., a product demo request or free account registration, which didn’t immediately lead to conversion)

    Position-Based Model 

    Position-Based attribution model (also known as the U-shaped model) allocates the biggest credit to the first and the last interaction (40% each). Then distributes the remaining 20% across other touches. 

    For many marketers, that’s the preferred multi-touch attribution model as it allows optimising both ToFU and BoFU channels. 

    Pros 

    • Helps establish the main channels for lead generation and conversion
    • Adds extra layers of visibility, compared to first- and last-touch attribution models 
    • Promotes budget allocation toward the most strategic touchpoints

    Cons 

    • Diminishes the importance of lead nurturing activities as more credit gets assigned to demand-gen and conversion-generation channels
    • Limited flexibility since it always assigns a fixed amount of credit to the first and last touchpoints, and the remaining credit is divided evenly among the other touchpoints

    How to Choose the Right Multi-Touch Attribution Model For Your Business 

    If you’re deciding which attribution model is best for your business, prepare for a heated discussion. Each one has its trade-offs as it emphasises or devalues the role of different channels and marketing activities.

    To reach a consensus, the best strategy is to evaluate each model against three criteria : Your marketing objectives, sales cycle length and data availability. 

    Marketing Objectives 

    Businesses generate revenue in many ways : Through direct sales, subscriptions, referral fees, licensing agreements, one-off or retainer services. Or any combination of these activities. 

    In each case, your marketing strategy will look different. For example, SaaS and direct-to-consumer (DTC) eCommerce brands have to maximise both demand generation and conversion rates. In contrast, a B2B cybersecurity consulting firm is more interested in attracting qualified leads (as opposed to any type of traffic) and progressively nurturing them towards a big-ticket purchase. 

    When selecting a multi-touch attribution model, prioritise your objectives first. Create a simple scoreboard, where your team ranks various channels and campaign types you rely on to close sales. 

    Alternatively, you can survey your customers to learn how they first heard about your company and what eventually triggered their conversion. Having data from both sides can help you cross-validate your assumptions and eliminate some biases. 

    Then consider which model would best reflect the role and importance of different channels in your sales cycle. Speaking of which….

    Sales Cycle Length 

    As shoppers, we spend less time deciding on a new toothpaste brand versus contemplating a new IT system purchase. Factors like industry, business model (B2C, DTC, B2B, B2BC), and deal size determine the average cycle length in your industry. 

    Statistically, low-ticket B2C sales can happen within just several interactions. The average B2B decision-making process can have over 15 steps, spread over several months. 

    That’s why not all multi-touch attribution models work equally well for each business. Time-decay suits better B2B companies, while B2C usually go for position-based or linear attribution. 

    Data Availability 

    Businesses struggle with multi-touch attribution model implementation due to incomplete analytics data. 

    Our web analytics tool captures more data than Google Analytics. That’s because we rely on a privacy-focused tracking mechanism, which allows you to collect analytics without showing a cookie consent banner in markets outside of Germany and the UK. 

    Cookie consent banners are mandatory with Google Analytics. Yet, almost 40% of global consumers reject it. This results in gaps in your analytics and subsequent inconsistencies in multi-touch attribution reports. With Matomo, you can compliantly collect more data for accurate reporting. 

    Some companies also struggle to connect collected insights to individual shoppers. With Matomo, you can cross-attribute users across browning sessions, using our visitors’ tracking feature

    When you already know a user’s identifier (e.g., full name or email address), you can track their on-site behaviours over time to better understand how they interact with your content and complete their purchases. Quick disclaimer, though, visitors’ tracking may not be considered compliant with certain data privacy laws. Please consult with a local authority if you have doubts. 

    How to Implement Multi-Touch Attribution

    Multi-touch attribution modelling implementation is like a “seek and find” game. You have to identify all significant touchpoints in your customers’ journeys. And sometimes also brainstorm new ways to uncover the missing parts. Then figure out the best way to track users’ actions at those stages (aka do conversion and events tracking). 

    Here’s a step-by-step walkthrough to help you get started. 

    Select a Multi-Touch Attribution Tool 

    The global marketing attribution software is worth $3.1 billion. Meaning there are plenty of tools, differing in terms of accuracy, sophistication and price.

    To make the right call prioritise five factors :

    • Available models : Look for a solution that offers multiple options and allows you to experiment with different modelling techniques or develop custom models. 
    • Implementation complexity : Some providers offer advanced data modelling tools for creating custom multi-touch attribution models, but offer few out-of-the-box modelling options. 
    • Accuracy : Check if the shortlisted tool collects the type of data you need. Prioritise providers who are less dependent on third-party cookies and allow you to identify repeat users. 
    • Your marketing stack : Some marketing attribution tools come with useful add-ons such as tag manager, heatmaps, form analytics, user session recordings and A/B testing tools. This means you can collect more data for multi-channel modelling with them instead of investing in extra software. 
    • Compliance : Ensure that the selected multi-attribution analytics software wouldn’t put you at risk of GDPR non-compliance when it comes to user privacy and consent to tracking/analysis. 

    Finally, evaluate the adoption costs. Free multi-channel analytics tools come with data quality and consistency trade-offs. Premium attribution tools may have “hidden” licensing costs and bill you for extra data integrations. 

    Look for a tool that offers a good price-to-value ratio (i.e., one that offers extra perks for a transparent price). 

    Set Up Proper Data Collection 

    Multi-touch attribution requires ample user data. To collect the right type of insights you need to set up : 

    • Website analytics : Ensure that you have all tracking codes installed (and working correctly !) to capture pageviews, on-site actions, referral sources and other data points around what users do on page. 
    • Tags : Add tracking parameters to monitor different referral channels (e.g., “facebook”), campaign types (e.g., ”final-sale”), and creative assets (e.g., “banner-1”). Tags help you get a clearer picture of different touchpoints. 
    • Integrations : To better identify on-site users and track their actions, you can also populate your attribution tool with data from your other tools – CRM system, A/B testing app, etc. 

    Finally, think about the ideal lookback window — a bounded time frame you’ll use to calculate conversions. For example, Matomo has a default windows of 7, 30 or 90 days. But you can configure a custom period to better reflect your average sales cycle. For instance, if you’re selling makeup, a shorter window could yield better results. But if you’re selling CRM software for the manufacturing industry, consider extending it.

    Configure Goals and Events 

    Goals indicate your main marketing objectives — more traffic, conversions and sales. In web analytics tools, you can measure these by tracking specific user behaviours. 

    For example : If your goal is lead generation, you can track :

    • Newsletter sign ups 
    • Product demo requests 
    • Gated content downloads 
    • Free trial account registration 
    • Contact form submission 
    • On-site call bookings 

    In each case, you can set up a unique tag to monitor these types of requests. Then analyse conversion rates — the percentage of users who have successfully completed the action. 

    To collect sufficient data for multi-channel attribution modelling, set up Goal Tracking for different types of touchpoints (MoFU & BoFU) and asset types (contact forms, downloadable assets, etc). 

    Your next task is to figure out how users interact with different on-site assets. That’s when Event Tracking comes in handy. 

    Event Tracking reports notify you about specific actions users take on your website. With Matomo Event Tracking, you can monitor where people click on your website, on which pages they click newsletter subscription links, or when they try to interact with static content elements (e.g., a non-clickable banner). 

    Using in-depth user behavioural reports, you can better understand which assets play a key role in the average customer journey. Using this data, you can localise “leaks” in your sales funnel and fix them to increase conversion rates.

    Test and Validated the Selected Model 

    A common challenge of multi-channel attribution modelling is determining the correct correlation and causality between exposure to touchpoints and purchases. 

    For example, a user who bought a discounted product from a Facebook ad would act differently than someone who purchased a full-priced product via a newsletter link. Their rate of pre- and post-sales exposure will also differ a lot — and your attribution model may not always accurately capture that. 

    That’s why you have to continuously test and tweak the selected model type. The best approach for that is lift analysis. 

    Lift analysis means comparing how your key metrics (e.g., revenue or conversion rates) change among users who were exposed to a certain campaign versus a control group. 

    In the case of multi-touch attribution modelling, you have to monitor how your metrics change after you’ve acted on the model recommendations (e.g., invested more in a well-performing referral channel or tried a new brand awareness Twitter ad). Compare the before and after ROI. If you see a positive dynamic, your model works great. 

    The downside of this approach is that you have to invest a lot upfront. But if your goal is to create a trustworthy attribution model, the best way to validate is to act on its suggestions and then test them against past results. 

    Conclusion

    A multi-touch attribution model helps you measure the impact of different channels, campaign types, and marketing assets on metrics that matter — conversion rate, sales volumes and ROI. 

    Using this data, you can invest budgets into the best-performing channels and confidently experiment with new campaign types. 

    As a Matomo user, you also get to do so without breaching customers’ privacy or compromising on analytics accuracy.

  • Pseudo-streaming mp4 files does not work with flash player

    11 mai 2013, par faridv

    I've got a problem with streaming audio on my website. I thought I could put the MP3 file inside an MP4 container with h264 codec, so I can use pseudo-streaming ability of mp4 codec.

    The code I'm using to convert my files is :

    ffmpeg -i 1.mp3 -y -b:a 32K -vn 1.mp4

    Pseudo-streaming (seeking in not-loaded parts of media) now works in HTML5 player but not in any Flash media players such as JWPlayer or FlowPlayer.

    I've tested my files on both Apache server with h264 module enabled and Nginx with mod_mp4 enabled, but without any lucks.

    I tried MP4Box, QTIndexSwapper and even creating a real video file by mixing of an image loop and my audio file.

    ffmpeg -y -i joojoo.png -i 2.mp3 -vcodec mjpeg havij.mp4
    MP4Box -add havij.mp4 -isma havij_new.mp4

    What am I doing wrong ? What can I do to make it work ?
