  • Matomo Celebrates 15 Years of Building an Open-Source & Transparent Web Analytics Solution

    30 juin 2022, par Matthieu Aubry — About, Community

           if ('function' === typeof window.playMatomoVideo){<br />
           window.playMatomoVideo(&quot;brand&quot;, &quot;#brand&quot;)<br />
           } else {<br />

           }<br />
      &lt;/script&gt;

    Fifteen years ago, I realised that people (myself included) were increasingly integrating the internet into their everyday lives, and it was clear that it would only expand in the future. It was an exciting new world, but the amount of personal data shared online, level of tracking and lack of security was a growing concern. Google Analytics was just launched then and was already gaining huge traction – so data from millions of websites started flowing into Google’s database, creating what was then the biggest centralised database about people worldwide and their actions online.

    So as a young engineering student, I decided we needed to build an open source and transparent solution that could help make the internet more secure and private while still providing organisations with powerful insights. I aimed to create a win-win solution for businesses and their digital consumers.

    And in 2007, I started developing Matomo with the help from Scott Switzer and Jennifer Langdon (who offered me an internship and support).   

    All thanks to the Matomo Community

    We have reached significant milestones and made major changes over the last 15 years, but we wouldn’t be where we are today without the Matomo Community.

    So I would like to celebrate and thank the hundreds of volunteer developers who have donated their time to develop Matomo, the thousands of contributors who provided feedback to improve Matomo, the countless supportive forum members, our passionate team of 40 at Matomo, the numerous translators who have translated Matomo and the 1.5 million websites that choose Matomo as their analytics platform.

  • CD-R Read Speed Experiments

    21 mai 2011, par Multimedia Mike — Science Projects, Sega Dreamcast

    I want to know how fast I can really read data from a CD-R. Pursuant to my previous musings on this subject, I was informed that it is inadequate to profile reading just any file from a CD-R since data might be read faster or slower depending on whether the data is closer to the inside or the outside of the disc.

    Conclusion / Executive Summary
    It is 100% true that reading data from the outside of a CD-R is faster than reading data from the inside. Read on if you care to know the details of how I arrived at this conclusion, and to find out just how much speed advantage there is to reading from the outside rather than the inside.

    Science Project Outline

    • Create some sample CD-Rs with various properties
    • Get a variety of optical drives
    • Write a custom program that profiles the read speed

    Creating The Test Media
    It’s my understanding that not all CD-Rs are created equal. Fortunately, I have 3 spindles of media handy : Some plain-looking Memorex discs, some rather flamboyant Maxell discs, and those 80mm TDK discs :



    My approach for burning is to create a single file to be burned into a standard ISO-9660 filesystem. The size of the file will be the advertised length of the CD-R minus 1 megabyte for overhead— so, 699 MB for the 120mm discs, 209 MB for the 80mm disc. The file will contain a repeating sequence of 0..0xFF bytes.

    Profiling
    I don’t want to leave this to the vagaries of any filesystem handling layer so I will conduct this experiment at the sector level. Profiling program outline :

    • Read the CD-ROM TOC and get the number of sectors that comprise the data track
    • Profile reading the first 20 MB of sectors
    • Profile reading 20 MB of sectors in the middle of the track
    • Profile reading the last 20 MB of sectors

    Unfortunately, I couldn’t figure out the raw sector reading on modern Linux incarnations (which is annoying since I remember it being pretty straightforward years ago). So I left it to the filesystem after all. New algorithm :

    • Open the single, large file on the CD-R and query the file length
    • Profile reading the first 20 MB of data, 512 kbytes at a time
    • Profile reading 20 MB of sectors in the middle of the track (starting from filesize / 2 - 10 MB), 512 kbytes at a time
    • Profile reading the last 20 MB of sectors (starting from filesize - 20MB), 512 kbytes at a time

    Empirical Data
    I tested the program in Linux using an LG Slim external multi-drive (seen at the top of the pile in this post) and one of my Sega Dreamcast units. I gathered the median value of 3 runs for each area (inner, middle, and outer). I also conducted a buffer flush in between Linux runs (as root : 'sync; echo 3 > /proc/sys/vm/drop_caches').

    LG Slim external multi-drive (reading from inner, middle, and outer areas in kbytes/sec) :

    • TDK-80mm : 721, 897, 1048
    • Memorex-120mm : 1601, 2805, 3623
    • Maxell-120mm : 1660, 2806, 3624

    So the 120mm discs can range from about 10.5X all the way up to a full 24X on this drive. For whatever reason, the 80mm disc fares a bit worse — even at the inner track — with a range of 4.8X - 7X.

    Sega Dreamcast (reading from inner, middle, and outer areas in kbytes/sec) :

    • TDK-80mm : 502, 632, 749
    • Memorex-120mm : 499, 889, 1143
    • Maxell-120mm : 500, 890, 1156

    It’s interesting that the 80mm disc performed comparably to the 120mm discs in the Dreamcast, in contrast to the LG Slim drive. Also, the results are consistent with my previous profiling experiments, which largely only touched the inner area. The read speeds range from 3.3X - 7.7X. The middle of a 120mm disc reads at about 6X.

    Implications
    A few thoughts regarding these results :

    • Since the very definition of 1X is the minimum speed necessary to stream data from an audio CD, then presumably, original 1X CD-ROM drives would have needed to be capable of reading 1X from the inner area. I wonder what the max read speed at the outer edges was ? It’s unlikely I would be able to get a 1X drive working easily in this day and age since the earliest CD-ROM drives required custom controllers.
    • I think 24X is the max rated read speed for CD-Rs, at least for this drive. This implies that the marketing literature only cites the best possible numbers. I guess this is no surprise, similar to how monitors and TVs have always been measured by their diagonal dimension.
    • Given this data, how do you engineer an ISO-9660 filesystem image so that the timing-sensitive multimedia files live on the outermost track ? In the Dreamcast case, if you can guarantee your FMV files will live somewhere between the middle and the end of the disc, you should be able to count on a bitrate of at least 900 kbytes/sec.

    Source Code
    Here is the program I wrote for profiling. Note that the filename is hardcoded (#define FILENAME). Compiling for Linux is a simple 'gcc -Wall profile-cdr.c -o profile-cdr'. Compiling for Dreamcast is performed in the standard KallistiOS manner (people skilled in the art already know what they need to know) ; the only variation is to compile with the '-D_arch_dreamcast' flag, which the default KOS environment adds anyway.

  • What is Funnel Analysis ? A Complete Guide for Quick Results

    25 janvier 2024, par Erin

    Your funnel is leaking.

    You’re losing visitors.

    You’re losing conversions and sales.

    But you don’t know how it’s happening, where it’s happening, or what to do about it.

    The reason ? You aren’t properly analysing your funnels.

    If you want to improve conversions and grow your business, you need to understand how to properly assess your sales funnels to set yourself up for success.

    In this guide, we’ll show you what funnel analysis is, why it’s important, and what steps you need to take to leverage it to improve conversions.

    What is funnel analysis ?

    Every business uses sales funnels, whether they know it or not.

    But most people aren’t analysing them, costing them conversions.

    What is funnel analysis?

    Funnel analysis is a marketing method to analyse the events leading to specific conversion points. 

    It aims to look at the entire journey of potential customers from the moment they first touch base with your website or business to the moment they click “buy.”

    It’s assessing what your audience is doing at every step of the journey.

    By assessing what actions are taking place at scale, you can see where you’re falling short in your sales funnel.

    You’ll see :

    1. Where prospects are falling off.
    2. Where people are converting well.

    By gaining this understanding, you’ll better understand the health of your website’s sales funnels and overall marketing strategy.

    With that knowledge, you can optimise your marketing strategy to patch those leaks, improve conversions and grow your business.

    Why funnel analysis is important

    Funnel analysis is critical because your funnel is your business.

    When you analyse your funnel, you’re analysing your business.

    You’re looking at what’s working and what’s not so you can grow revenue and profit margins.

    Funnel analysis lets you monitor user behaviour to show you the motivation and intention behind their decisions.

    Here are five reasons you need to incorporate funnel analysis into your workflow.

    Why funnel analysis is important.

    1. Gives insights into your funnel problems

    The core purpose of funnel analysis is to look at what’s going on on your website.

    What are the most effective steps to conversion ?

    Where do users drop off in the conversion process ?

    And which pages contribute the most to conversion or drop-offs ?

    Funnel analysis helps you understand what’s going on with your site visitors. Plus, it helps you see what’s wrong with your funnel.

    If you aren’t sure what’s happening with your funnel, you won’t know what to improve to grow your revenue.

    2. Improves conversions

    When you know what’s going on with your funnel, you’ll know how to improve it.

    To improve your conversion funnel, you need to close the leaks. These are areas where website visitors are falling off.

    It’s the moment the conversion is lost.

    You need to use funnel analysis to give insight into these problem areas. Once you can see where the issue is, you can patch that leak and improve the percentage of visitors who convert.

    For example, if your conversion rate on your flagship product page has plateaued and you can’t figure out how to increase conversions, implementing a funnel analysis tactic like heatmaps will show you that visitors are spending time reading your product description. Still, they’re not spending much time near your call to action.

    Matomo's heatmaps feature

    This might tell you that you need to update your description copy or adjust your button (i.e. colour, size, copy). You can increase conversions by making those changes in your funnel analysis insights.

    3. Improves the customer experience

    Funnel analysis helps you see where visitors spend their time, what elements they interact with and where they fall off.

    One of the key benefits of analysing your funnel is you’ll be able to help improve the experience your visitors have on your website.

    For example, if you have informational videos on a specific web page to educate your visitors, you might use the Media Analytics feature in your web analytics solution to find out that they’re not spending much time watching them.

    This could lead you to believe that the content itself isn’t good or relevant to them.

    But, after implementing session recordings within your funnel analysis, you see people clicking a ton near the play button. This might tell you that they’re having trouble clicking the actual button on the video player due to poor UX.

    In this scenario, you could update the UX on your web page so the videos are easy to click and watch, no matter what device someone uses.

    With more video viewers, you can provide value to your visitors instead of leaving them frustrated trying to watch your videos.

    4. Grows revenue

    This is what you’re likely after : more revenue.

    More often than not, this means you need to focus on improving your conversion rate.

    Funnel analysis helps you find those areas where visitors are exiting so you can patch those leaks up and turn more visitors into customers.

    Let’s say you have a conversion rate of 1.7%.

    You get 50,000 visitors per month.

    Your average order is $82.

    Even if you increase your conversion rate by 10% (to 1.87%) through funnel analysis, here’s the monthly difference in revenue :

    Before : $69,700
    After : $76,670

    In one year, you’ll make nearly $80,000 in additional revenue from funnel analysis alone.

    Different types of funnel analysis

    There are a few different types of funnel analysis.

    How you define success in your funnel all comes down to one of these four pillars.

    Depending on your goals, business and industry, you may want to assess the different funnel analyses at different times.

    1. Pageview funnel analysis

    Pageview funnel analysis is about understanding how well your website content is performing. 

    It helps you enhance user experience, making visitors stay longer on your site. By identifying poor performing pages (pages with high exit rates), you can pinpoint areas that need optimisation for better engagement.

    2. Conversion funnel analysis

    Next up, we’re looking at conversion funnel analysis.

    This type of funnel analysis is crucial for marketers aiming to turn website visitors into action-takers. This involves tracking and optimising conversion goals, such as signing up for newsletters, downloading ebooks, submitting forms or signing up for free trials. 

    The primary goal of conversion funnel analysis is to boost your website’s overall conversion rates.

    3. E-commerce funnel analysis

    For businesses selling products online, e-commerce funnel analysis is essential. 

    It involves measuring whether your products are being purchased and finding drop-off points in the purchasing process. 

    By optimising the e-commerce funnel, you can enhance revenue and improve the overall efficiency of your sales process.

    How to conduct funnel analysis

    Now that you understand what funnel analysis is, why it’s important, and the different types of analysis, it’s time to show you how to do it yourself.

    To get started with funnel analysis, you need to have the right web analytics solution.

    Here are the most common funnel analysis tools and methods you can use :

    1. Funnel analytics

    If you want to choose a single tool to conduct funnel analysis, it’s an all-in-one web analytics tool, like Matomo.

    Matomo funnel analytics example one.

    With Matomo’s Funnel Analytics, you can dive into your whole funnel and analyse each step (and each step’s conversion rate).

    Matomo funnel analytics stages.

    For instance, if you look at the example above, you can see the proceed rate at each funnel step before the conversion page.

    This means you can improve each proceed rate, to drive more traffic to your conversion page in order to increase conversion rates.

    In the above snapshot from Matomo, it shows visitors starting on the job board overview page, moving on to view specific job listings. The goal is to convert these visitors into job applicants.

    However, a significant issue arises at the job view stage, where 95% of visitors don’t proceed to job application. To increase conversions, we need to first concentrate on improving the job view page.

    2. Heatmaps

    Heatmaps is a behaviour analytics tool that lets you see different visitor activities, including :

    • Mouse movement
    • How far down visitors scroll
    • Clicks

    You can see which elements were clicked on and which weren’t and how far people scroll down your page.

    Heatmaps in Matomo

    A heatmap lets you see which parts of a page are getting the most attention and which parts go unnoticed by your users.

    For example, if, during your funnel analysis, you see that a lot of visitors are falling off after they land on the checkout page, then you might want to add a heatmap on your checkout page to see where and why people are exiting.

    3. Session recordings

    Want to see what individual users are doing and how they’re interacting with your site ?

    Then, you’ll want to check out session recordings.

    A session recording is a video playback of a visitor’s time on your website.

    Session Recordings

    It’s the most effective method to observe your visitors’ interactions with your site, eliminating uncertainty when identifying areas for funnel improvement.

    Session recordings instill confidence in your optimisation efforts by providing insights into why and where visitors may be dropping off in the funnel.

    4. A/B testing

    If you want to take the guesswork out of optimising your funnel and increasing your conversions, you need to start A/B testing.

    An A/B test is where you create two versions of a web page to determine which one converts better.

    Matomo A/B Test feature

    For example, if your heatmaps and session recordings show that your users are dropping off near your call to action, it may be time to test a new version.

    You may find that by simply testing a different colour button, you may increase conversions by 20% or more.

    5. Form analytics

    Are you trying to get more leads to fill out forms on your site ?

    Well, Form Analytics can help you understand how your website visitors interact with your signup forms.

    You can view metrics such as starter rate, conversion rate, average hesitation time and average time spent.

    This information allows you to optimise your forms effectively, ultimately maximising your success.

    Let’s look at the performance of a form using Matomo’s Form Analytics feature below.

    In the Matomo example, our starter rate stands at a solid 60.1%, but there’s a significant drop to a submitter rate of 29.3%, resulting in a conversion rate of 16.3%.

    Looking closer, people are hesitating for about 16.2 seconds and taking nearly 1 minute 39 seconds on average to complete our form.

    This could indicate our form is confusing and requesting too much. Simplifying it could help increase sign-ups.

    See first-hand how Concrete CMS tripled their leads using Form Analytics in Matomo.
