  • The Ultimate Guide to HeatMap Software

    20 septembre 2021, par Ben Erskine — Analytics Tips, Plugins, Heatmaps

    One of the most effective ways to improve the user experience on your website is to use heatmap software. As well as in-depth insight on how to improve your website and funnels, user behaviour analytics complement traditional web metrics with insights from your customers’ point of view. 

    Heatmap software shows actual user behaviour. That means that you have a visual representation of why a customer might not be converting instead of guessing. 

    By tracking clicks, mouse movement, and page scrolling as well as analysing above the fold content engagement and overall session recordings, heatmap software helps improve user experience and therefore customer retention and conversions.  

    Matomo Heatmaps - Hotjar alternative

    What is heatmap software ?

    Heatmap software is a data visualisation tool that uses colour to show what actions a user is taking on a website. 

    If there is a design element on a page that many users engage with, it will show as red/hot. For elements that are less engaging, it will show on the analysis as blue/cold. 
     
    Heatmap software like Matomo helps businesses to improve user experience and increase conversions by tracking elements such as :
    Using data visualisation software like a heatmap provides more in-depth data when combined with standard website metrics. 

    What is heatmap software used for ?

    Heatmap software tracks website user behaviour to improve website performance and increase conversions. 

    Heatmaps can show you a detailed analysis of : 

    • Where visitors are clicking (or not clicking) 
    • Where visitors are hovering with their mouse
    • How far users are scrolling or stopping 
    • Where the focus is above the fold 
    • What roadblocks or frictions customers are facing in the sales funnel

    Analysing activity on your website and across channels from your customers point of view is critical in developing a customer-centric business model. 

    This is because heatmaps not only show you what customers are doing but why they are doing it. 

    Heatmap software is ideal for businesses updating and redesigning websites. It also helps to answer important growth questions such as “how can we improve our user experience ?” and “why is our sales funnel not converting better ?”. 

    The benefits of using data visualisation like heatmaps for your website

    Heatmaps are critical for improving websites because they drastically improve customer experience. 

    Customer experience is one of the most important factors in modern business success. A Walker study found that customer experience is one of the biggest differentiators between brands, overtaking other factors such as price. 

    Where straightforward website metrics show customers left a page without action, data visualisation and session recordings show what happens in between them arriving and leaving. This gives web developers and marketers invaluable insights to improve website design and ultimately increase conversions. 

    How heatmap software improves your website and conversions

    There are a few key ways that heatmap software boosts website performance and conversions. All of them focus on both creating a seamless buyer journey and using data to improve results over time. 

    How heatmap software improves conversions ; 

    • By improving UX and usability– 70% of online businesses fail due to bad usability. Heatmaps identify user frustrations and optimise accordingly 
    • By improving content structure – Heatmaps take the guesswork out of design layout and content structure by showing real visitor experiences on your website 
    • By comparing A/B landing pages – Using heatmaps on alternate landing pages can show you why conversions are working or not working based on user activity on the page
    • By optimising across devices – See how your visitors are interacting with your content to learn how well optimised your website is for various devices and remove roadblocks 

    Heatmap analytics you need to improve website user experience

    Click heatmap

    Click heatmaps are useful for two key reasons.

    Firstly, it shows where website users are clicking. 

    Heatmaps that show clicks give you a visual representation of whether copy and CTA links are clear from the customers’ point of view. It can also show whether a customer is clicking on a design feature that doesn’t link anywhere. 

    Secondly, it shows where website users are not clicking. This is just as important when developing funnels and improving user experiences.

    For example, you may have a CTA button for a free trial or purchase. A click heatmap analysis would show if this isn’t clicked on mobile devices and informs developers that it needs to be more mobile-friendly.

    Mouse move or hover heatmap

    Like a click heatmap, a mouse hover heatmap shows how you can improve the overall user experience.

    For example, hover heatmaps identify where your visitors engage on a particular webpage. Ideally, of course, you want them to engage with CTAs. Analysing their mouse movements or where they are hovering for more information gives you an indication of any page elements that are distracting them or not working.

    Matomo's heatmaps feature

    Scroll heatmap

    A scroll heatmap uses colours to visualise how far down in a page your visitors scroll. For most web pages, the top will have the most impressions and will naturally get less views (i.e. get “colder” on the heatmap) further down the page. 

    This lets you find out if there is important content positioned too far down the page or if the page is designed to encourage users to keep scrolling.

    No matter how good your product or service is, it won’t convert if potential customers aren’t engaged and scrolling far enough to see it.

    Above the fold analysis 

    Above the fold is the content that a visitor sees without scrolling. 

    In a heatmap, the “Average Above the Fold” line will show you how much content your visitors see on average when they open your page. It also shows whether the page design is engaging, whether it encourages visitors to keep scrolling, and whether important information is too far down the page and therefore being missed. 

    Above the fold analysis is arguably the most important as this is the section that the highest number of traffic will see. Using this information ensures that the right content for conversion is seen by the highest number of visitors. 

    Session recording

    Session Recording lets you record a real visitor session, so you can see clicks, mouse movements, scrolls, window resizes, page changes, and form interactions all in one. 

    They allow you to understand the experience from the point of view of your visitor and then optimise your website to maximise your success.

    Heatmap software like Matomo takes this one step further and allows you to gather session recordings for individual segments. By analysing sessions based on segments, you can further personalise and optimise based on customer history and patterns.

    Final thoughts on heatmap software 

    Heatmap software improves your user experience by easily spotting critical issues that you can then address. 

    As well as that, heatmap analytics like clicks, mouse movement, scroll, above the fold analysis and session recordings increase your marketing ROI by making the most of your existing traffic. 

    It’s a win-win ! 

    Now that you know what heatmap software is, the benefits of using heatmaps on your website and how it can improve your user experience, check out this user guide on heatmap analytics. 

  • How to combine multiple video blobs in js without gap ?

    5 septembre 2021, par Pouria Moosavi

    I have an array of urls. I download them with fetch and then get blob from each response with await res.blob(). I need to concat all these blobs together to make a full video out of it, I tried to push each blob into an array and make a file new File(blobArray, "test") but the result has a gap between each blob.

    


    I've tried to save each blob as a separate file and concat them with ffmpeg -f concat -safe 0 -i text -c copy out3.mp4 and the result was perfect. So I know that my blobs are correct and the problem is how I am combining them together.

    


    This is my full code :

    Unfortunately links will expire soon but I think it is obvious what I am trying to do.

    


    So Is there any way to cancat blobs in JS and create the entire video smoothly like the ffmpeg does ?

    


    Thanks in advance.

    


  • Why is the filesize different when swapping audio tracks using ffmeg ?

    20 août 2021, par Brian

    I have a movie that I have encoded using Handbrake on a Mac a long time ago. When I encoded the movie, I put the stereo audio as track 1 and the 5.1 audio as track 2. The starting filesize is 853,320,914 bytes. Below is the data from ffprobe.

    My goal is to swap the stereo audio track with the 5.1 audio track and make the 5.1 audio track the default without having to reencode. To do this, I used the following command :

    


    ffmpeg -i "Annabelle - Comes Home (2019)/Annabelle - Comes Home (2019)_old.m4v" -map 0:v:0 -map 0:a:1 -map 0:a:0 -disposition:a:0 default -disposition:a:1 none -c copy "Annabelle - Comes Home (2019)/Annabelle - Comes Home (2019).m4v"

    


    Everything works as it should, I think anyways as I didn't get any errors...

    What I don't understand is why is the file size different ? The resulting file is larger at 854,292,790 bytes. Shouldn't the file sizes be the same since I literally just swapped tracks 0 and 1 ?
