Blog series part 1 : How to use Matomo to increase customer acquisitions for your business
2 septembre 2020, par Joselyn Khor — Analytics Tips, MarketingAre you investing time and money into marketing your business and unsure if it’s paying off ? Web analytics provides the tools and insights to help you know which marketing channels to target and focus on. Without it you might be going in blind and missing opportunities that might’ve been easily found in your metrics.
Increasing acquisition cheat sheet
To increase customer acquisition on your website you need to first attract the right visitors to your website. Then capturing their attention and engaging them in your content. Finally you’ll want to convert by driving them through a streamlined funnel/buyer’s journey on your website all backed up by data.
So, how do you attract audiences to your site with a web analytics tool like Matomo ?
- Figure out who your audience is through the Visitor Profiles feature.
- Calculate the Cost of Customer Acquisition (CAC) to plan for growth. To grow and make your business/website sustainable, you’ll need to earn more money from a customer than you spend on acquiring them. How to calculate : Divide marketing spend by the number of customers acquired.
- Figure out which marketing channels e.g., social media, PPC, SEO, content marketing, etc., you should invest more in and which of those you should focus less on.
How to increase acquisitions with Matomo
1. Use the Acquisitions feature
Matomo Analytics has a dedicated Acquisition feature to help with some of the heavy-lifting, making it easy for you to formulate targeted acquisition plans.
This feature helps you learn who your potential customers are and figure out what marketing channels are converting the best for these visitors.
- Learn what traffic you get from external websites : Knowing who’s helping you succeed from external websites is a crucial step to be able to focus your attention. Paid sponsorships, guest blog posts or even spending more on advertising on the particular website could result in greater traffic.
- Social Networks : See which social media channels are connecting with the audiences you want. Take the guesswork out by using only the ones you need. By finding out which social channels your ideal audience prefers, you can generate shareable, convincing and engaging content to drive shares and traffic through to your site.
- Campaigns : Your marketing team may have spent precious time and resource coming up with campaigns that are designed to succeed, but how can you be so sure ? With Campaigns you can understand what marketing campaigns are working, what aren’t, and shift your marketing efforts accordingly to gain more visitors, more effectively, with less costs. Keep track of every ad and content piece you display across internal and external channels to see which is having the biggest impact on your business objectives. Learn more

2. Use funnels
Creating conversion funnels gives you the big picture on whether your acquisition plans are paying off and where they may be falling short.
If the ultimate goal of your site is to drive conversions, then each funnel can tell you how effectively you’re driving traffic through to your desired outcome.
By integrating this with Visitor Profiles, you can view historic visitor profiles of any individual user at any stage of the conversion funnel. You see the full user journey at an individual level, including where they entered the funnel from and where they exited. Learn more
How to amplify acquisition strategies with Funnels : Use conversion funnels to guide acquisition as you can tell which entry point is bringing the most success and which one needs more attention. Tailor your strategies to zone in on areas that have the most potential. You can identify where your visitors are encountering obstacles from the start, that are stopping them from progressing through their journey on your site.
3. Study Visitor Profiles
Visitor Profiles helps you understand visitors on a user-by-user basis, detailing each visitors’ history into a profile which summarises every visit, action and purchase made.
Better understand :
-
Why your visitors viewed your website.
-
Why your returning visitors continue to view your website.
-
What specifically your visitors are looking for and whether they found it on your website.
The benefit is being able to see how a combination of acquisition channels play a part in a single buyer’s journey.
How Visitor Profiles helps with acquisition : By understanding the full behavioural patterns of any individual user coming through from external channels, you’ll see the path that led them to take action, where they may have gotten lost, and how engaged they are with your business over time. This gives you an indication of what kinds of visitors you’re attracting and helps you craft a buyer persona that more accurately reflects the audience most interested in you.
4. Focus on SEO efforts
Every acquisition plan needs a focus on maximising your Search Engine Optimization (SEO) efforts. When it comes to getting conclusive search engine referrer metrics, you need to be sure you’re getting ALL the insights to drive your SEO strategy.
Integrate Google, Bing and Yahoo search consoles directly into your Matomo Analytics. This helps kickstart your acquisition goals as you rank highly for keywords that get the most traffic to your website.
As another major SEO benefit, you can see how the most important search keywords to your business increased and decreased in ranking over time.
How to amplify acquisitions strategies with search engines and keywords : By staying on top of your competitors across ALL search engines, you may uncover traffic converting highly from one search engine, or find you could be losing traffic and business opportunities to your competitors across others.
5. Look at the Multi Attribution feature
Multi Attribution lets you measure the success of every touchpoint in the customer journey.
Accurately measure (and assign value to) channels where visitors first engaged with your business, where they came from after that, as well as the final channel they came from before purchasing your product or service.
No longer falsely over-estimate any marketing channel and make smarter decisions when determining acquisition spend to accurately calculate the Customer Acquisition Cost (CAC). Learn more
6. Set your Goals
What are the acquisition goals you want to achieve the most ? The Goals feature lets you measure the most important metrics you need to grow your business.
Goals are crucial for building your marketing strategy and acquiring new customers. The more goals you track, the more you can learn about behavioural changes as you implement and modify paths that impact acquisition and conversions over time. You’ll understand which channels are converting the best for your business, which cities/countries are most popular, what devices will attract the most visitors and how engaged your visitors are before converting.
This way you can see if your campaigns (SEO, PPC, signups, blogs etc.) or optimising efforts (A/B Testing, Funnels) have made an impact with the time and investment you have put in. Learn more
7. Set Advanced Ecommence reporting
If your website’s overall purpose is to generate revenue whether it be from an online store, asking for donations or from an online paid membership site ; the Ecommerce feature gives you comprehensive insights into your customers’ purchasing behaviours.
When you use Ecommerce analytics, you heavily reduce risk when marketing your products to potential customers because you will understand who to target, what to target them with and where further opportunities exist to have the greatest impact for your business. Learn more
Key takeaway
Having the tools to ensure you’re creating a well planned acquisition strategy is key to attracting and capturing the attention of potential visitors/leads, and then driving them through a funnel/buyer’s journey on your website. Because of Matomo’s reputation as a trusted analytics platform, the features above can be used to assist you in making smarter data-driven decisions. You can pursue different acquisition avenues with confidence and create a strategy that’s agile and ready for success, all while respecting user privacy.

how to stream h.264 video with mp3 audio using libavcodec ?
29 août 2020, par dasgI read h.264 frames from webcamera and capture audio from microphone. I need to stream live video to ffserver. During debug I read video from ffserver using ffmpeg with following command :



ffmpeg -i http://127.0.0.1:12345/robot.avi -vcodec copy -acodec copy out.avi



My video in output file is slightly accelerated. If I add a audio stream it is accelerated several times. Sometimes there is no audio in the output file.



Here is my code for encoding audio :



#include "v_audio_encoder.h"

extern "C" {
#include <libavcodec></libavcodec>avcodec.h>
}
#include <cassert>

struct VAudioEncoder::Private

I think my problem is in PTS and DTS. Can anyone help me ?

ffmpeg command execution never stops
19 août 2020, par Khawar RazaI am trying to concatenate 3 videos of different resolutions and overlaying 2 videos as transition effects(though the chroma key color removal is not yet implemented) between videos using below command :
