• Custom Segmentation Guide : How it Works & Segments to Test

  13 novembre 2023, par Erin — Analytics Tips, Uncategorized

  Struggling to get the insights you’re looking for with premade reports and audience segments in your analytics ?

  Custom segmentation can help you better understand your customers, app users or website visitors, but only if you know what you’re doing.

  You can derive false insights with the wrong segments, leading your marketing campaigns or product development in the wrong direction.

  In this article, we’ll break down what custom segmentation is, useful custom segments to consider, how new privacy laws affect segmentation options and how to create these segments in an analytics platform.

  What is custom segmentation ?

  Custom segmentation is when you divide your audience (customers, users, website visitors) into bespoke segments of your own design, not premade segments designed by the analytics or marketing platform provider.

  To do this, you single out “custom segment input” — data points you will use to pinpoint certain users. For example, it could be everyone who has visited a certain page on your site.

  

  Segmentation isn’t just useful for targeting marketing campaigns and also for analysing your customer data. Creating segments is a great way to dive deeper into your data beyond surface-level insights.

  You can explore how various factors impact engagement, conversion rates, and customer lifetime value. These insights can help guide your higher-level strategy, not just campaigns.

  How custom segments can help your business

  As the global business world clamours to become more “data-driven,” even smaller companies collect all sorts of data on visitors, users, and customers.

  However, inexperienced organisations often become “data hoarders” without meaningful insights. They have in-house servers full of data or gigabytes stored by Google Analytics and other third-party providers.

  

  One way to leverage this data is with standard customer segmentation models. This can help you get insights into your most valuable customer groups and other standard segments.

  Custom segments, in turn, can help you dive deeper. They help you unlock insights into the “why” of certain behaviours. They can help you segment customers and your audience to figure out :

  • Why and how someone became a loyal customer
  • How high-order-value customers interact with your site before purchases
  • Which behaviours indicate audience members are likely to convert
  • Which traffic sources drive the most valuable customers

  This specific insight’s power led Gartner to predict that 70% of companies will shift focus from “big data” to “small and wide” by 2025. The lateral detail is what helps inform your marketing strategy. 

  You don’t need the same volume of data if you’re analysing and segmenting it effectively.

  Custom segment inputs : 6 data points you can use to create valuable custom segments 

  To help you get started, here are six useful data points you can use as a basis to create segments — AKA customer segment inputs :

  

  Visits to certain pages

  A basic data point that’s great for custom segments is visits to certain pages. Create segments for popular middle-of-funnel pages and compare their engagement and conversion rates. 

  For example, if a user visits a case study page, you can compare their likelihood to convert vs. other visitors.

  This is a type of behavioural segmentation, but it is the easiest custom segment to set up in terms of analysis and marketing efforts.

  Visitors who perform certain actions

  The other important type of behavioural segment is visitors or users who take certain actions. Think of things like downloading a file, clicking a link, playing a video or scrolling a certain amount.

  For instance, you can create a segment of all visitors who have downloaded a white paper. This can help you explore, for example, what drives someone to download a white paper. You can look at the typical user journey and make it easier for them to access the white paper — especially if your sales reps indicate many inbound leads mention it as a key driver of their interest.

  User devices

  Device-based segmentation lets you compare engagement and conversion rates on mobile, desktop and tablets. You can also get insights into their usage patterns and potential issues with certain mobile elements.

  

  This is one aspect of technographic segmentation, where you segment based on users’ hardware or software. You can also create segments based on browser software or even specific versions.

  Loyal or high-value customers

  The best way to get more loyal or high-value customers is to explore their journey in more detail. These types of segments can help you better understand your ideal customers and how they act on your site.

  You can then use this insight to alter your campaigns or how you communicate with your target audience.

  For example, you might notice that high-value customers tend to come from a certain source. You can then focus your marketing efforts on this source to reach more of your ideal customers.

  Visitor or customer source

  You need to track the results if you’re investing in marketing (like an influencer campaign or a sponsored post) outside platforms with their own analytics.

  

  Before you can create a reliable segment, you need to make sure that you use campaign tracking parameters to reliably track the source. You can use our free campaign tracking URL builder for that.

  Demographic segments — location (country, state) and more

  Web analytics tools, such as Matomo, use visitors’ IP addresses to pinpoint their location more accurately by cross-referencing with a database of known and estimated IP locations. In addition, these tools can detect a visitor’s location through the language settings in their browser. 

  This can help create segments based on location or language. By exploring these trends, you can identify patterns in behaviour, tailor your content to specific audiences, and adapt your overall strategy to better meet the preferences and needs of your diverse visitor base.

  How new privacy laws affect segmentation options

  Over the past few years, new legislation regarding privacy and customer data has been passed globally. The most notable privacy laws are the GDPR in the EU, the CCPA in California and the VCDPA in Virginia.

  

  For most companies, it can save a lot of work and future headaches to choose a GDPR-compliant web analytics solution not only streamlines operations, saving considerable effort and preventing future headaches, but also ensures peace of mind by guaranteeing the collection of compliant and accurate data. This approach allows companies to maintain compliance with privacy regulations while remaining firmly committed to a data-driven strategy.

  Create your very own custom segments in Matomo (while ensuring compliance and data accuracy)

  Crafting precise marketing messages and optimising ROI is crucial, but it becomes challenging without the right tools, especially when it comes to maintaining accurate data.

  That’s where Matomo comes in. Our privacy-friendly web analytics platform is GDPR-compliant and ensures accurate data, empowering you to effortlessly create and analyse precise custom segments.

• ffmpeg streaming fails to stream over internet to twitch.tv

  15 avril 2021, par josh joyer

  I did already streaming to twitch.tv with command :

  


  ffmpeg -stream_loop -1 -i 9stream.wav 
-f dshow -i audio="mic"
 -f dshow -i audio="realTek" 
-filter_complex "[0:a]volume=2[a0];[1:a]volume=1.5[a1];[2:a]volume=1.5[a2];[a0][a1][a2]amix=inputs=3"
 -f dshow -i video="USB2.0 PC CAMERA" 
-ac 1 -ar 11025 -acodec libmp3lame -c:v libx264 -b:v 100k -f flv -s 80x120 
rtmp://live.twitch.tv/app/live_streamingKey


  


  It was most advanced command that I used to stream online.

  


  (I do not know how to make enter in here so I put double enter)

  


  9stream.wav was played in loop as background music

  


  microphone was added

  


  stereoMix named realTek was the playback of system sounds

  


  volume was adjusted and all sounds mixed into one stream

  


  camera view was added

  


  THEN network flow was reduced by sending only one channel with low frequency of 11025 with lowest

  


  possible data size made by mp3 encoder and libx264 was used to encode video in png files.

  


  It was working fine SO I decided to make final version

  


  (this one worked with all sounds(background music,microphone,system sounds) and camera)

  


  Final version was about adding screen view and logo.

  


  I succeded writing everything to disc with command :

  


  ffmpeg 
-stream_loop -1 -i 9stream.wav 
-f dshow -i audio="mic" 
-f dshow -i audio="stereoMixRealtek" 
-i camera.png 
-f gdigrab -framerate 1 -i desktop 
-f dshow -framerate 15 -i video="USB2.0 PC CAMERA" 
-filter_complex "[0:a]volume=2[a0];[1:a]volume=1.5[a1];[2:a]volume=1.5[a2];
[a0][a1][a2]amix=inputs=3[aMix];
[4:v]scale=200:-1[v4];[5:v]scale=50:-1[v5];
[v4][v5]overlay=(W-w)-5:(H-h)-5[vScreenCam];
[vScreenCam][3:v]overlay=5:5[v]" 
-map "[v]" -map "[aMix]" -ac 1 -ar 11025 -c:a libmp3lame -r 1 -c:v libx264 output.mkv


  


  That was

  


  background music

  


  microphone

  


  system sounds

  


  logo picture

  


  screen view

  


  camera

  


  adjusting sound volume

  


  mixing sounds

  


  reducing size of screen view and camera view

  


  overlaying reduced camera view over reduced screen view

  


  adding logo

  


  choosing final view, final mixed sounds,

  


  reducing data size to one channel, reducing sample frequency,

  


  choosing mp3 codec to reduce final data size,

  


  choosing minimal framerate of one per second to reduce data size

  


  choosing libx264 codec for video.

  


  THEN I tried to use final command for network streaming with slight modification :

  


  ffmpeg 
-stream_loop -1 -i 9stream.wav 
-f dshow -i audio="mic" 
-f dshow -i audio="stereo mix" 
-i camera.png 
-f gdigrab -framerate 1 -i desktop 
-f dshow -framerate 15 -i video="USB2.0 PC CAMERA" 
-filter_complex "[0:a]volume=2[a0];[1:a]volume=1.5[a1];[2:a]volume=1.5[a2];
[a0][a1][a2]amix=inputs=3[aMix];
[4:v]scale=200:-1[v4];[5:v]scale=50:-1[v5];
[v4][v5]overlay=(W-w)-5:(H-h)-5[vScreenCam];[vScreenCam][3:v]overlay=5:5[v]" 
-map "[v]" -map "[aMix]" 
-ac 1 -ar 11025 -c:a libmp3lame -r 1 -c:v libx264 -b:v 100k -b:a 10k -f flv rtmp://live.twitch.tv/app/live_streamingKey


  


  I added parameter
-b:v 100k to reduce video flow
-b:a 10k to reduce sound flow
-f flv to be good for twitch.tv otherwise it would not accept stream

  


  BUT ffmpeg is always stopping sending data with message like this :

  Main message from above was :

  


  [flv @ 0000009a40865940] Packets poorly interleaved, failed to avoid negative timestamp -3900 in stream 0.


  


  It was problem to stream 0 so it was mixed sounds stream BUT earlier it was fine with mixing

  


  and sending mix over internet BUT after I added screen view and scaling it failed to work.

  


  What is problem ?

  


  How to fix it ?

  


  Since I was able to do this to stream to disc I would assume that

  


  computer processing power is enough. Since I was able to stream over internet mixed sounds I

  


  would assume that it is not problem here. So the problem must be with sending

  


  screen view. BUT I put framerate 1 per second and downsized its resolution. I compressed

  


  sounds as much as I could. I added -b:a and -b:v commands to reduce network flow.

  


  WHAT ELSE COULD I DO TO FIX IT ?
