• Anomalie #3133 : Pas moyen d’ajouter ou de retirer un auteur à un article

  21 janvier 2014, par b b

  Après quelques essais :

  - le formulaire fonctionne bien sans ajax (en virant la classe ajax de la div qui l’englobe)
  - le problème vient du fait que la variable visible=1 n’est pas passée dans le POST quand on clique sur le button :

  http://core.spip.org/projects/spip/repository/entry/spip/prive/formulaires/editer_liens.html#L44

  Si on ajoute on type="submit" au bouton en question, la variable visible=1 est bien passée au POST et cela fonctionne.

  Ce problème avec les buttons sans attribut type=submit fait que même si la liste des auteurs est affichée, l’ajout d’un auteur ne fonctionne pas non plus.

• What is Google Analytics data sampling and what’s so bad about it ?

  16 août 2019, par Joselyn Khor — Analytics Tips, Development
  What is Google Analytics data sampling, and what’s so bad about it ?

  Google (2019) explains what data sampling is :

  “In data analysis, sampling is the practice of analysing a subset of all data in order to uncover the meaningful information in the larger data set.”[1]

  This is basically saying instead of analysing all of the data, there’s a threshold on how much data is analysed and any data after that will be an assumption based on patterns.

  Google’s (2019) data sampling thresholds :

  Ad-hoc queries of your data are subject to the following general thresholds for sampling :
  [Google] Analytics Standard : 500k sessions at the property level for the date range you are using
  [Google] Analytics 360 : 100M sessions at the view level for the date range you are using (para. 3) [2]

  This threshold is limiting because your data in GA may become more inaccurate as the traffic to your website increases.

  Say you’re looking through all your traffic data from the last year and find you have 5 million page views. Only 500K of that 5 million is accurate ! The data for the remaining 4.5 million (90%) is an assumption based on the 500K sample size.

  This is a key weapon Google uses to sell to large businesses. In order to increase that threshold for more accurate reporting, upgrading to premium Google Analytics 360 for approximately US$150,000 per year seems to be the only choice.

  What’s so bad about data sampling ?

  It’s unfair to say sampled data is to be disregarded completely. There is a calculation ensuring it is representative and can allow you to get good enough insights. However, we don’t encourage it as we don’t just want “good enough” data. We want the actual facts.

  In a recent survey sent to Matomo customers, we found a large proportion of users switched from GA to Matomo due to the data sampling issue.

  The two reasons why data sampling isn’t preferable : 

  1. If the selected sample size is too small, you won’t get a good representative of all the data. 
  2. The bigger your website grows, the more inaccurate your reports will become.

  An example of why we don’t fully trust sampled data is, say you have an ecommerce store and see your GA revenue reports aren’t matching the actual sales data, due to data sampling. In GA you may be seeing revenue for the month as $1 million, instead of actual sales of $800K.

  The sampling here has caused an inaccuracy that could have negative financial implications. What you get in the GA report is an estimated dollar figure rather than the actual sales. Making decisions based on inaccurate data can be costly in this case. 

  Another disadvantage to sampled data is that you might be missing out on opportunities you would’ve noticed if you were given a view of the whole. E.g. not being able to see real patterns occurring due to the data already being predicted. 

  By not getting a chance to see things as they are and only being able to jump to the conclusions and assumptions made by GA is risky. The bigger your business grows, the less you can risk making business decisions based on assumptions that could be inaccurate. 

  If you feel you could be missing out on opportunities because your GA data is sampled data, get 100% accurately reported data. 

  The benefits of 100% accurate data

  Matomo doesn’t use data sampling on any of our products or plans. You get to see all of your data and not a sampled data set.

  Data quality is necessary for high impact decision-making. It’s hard to make strategic changes if you don’t have confidence that your data is reliable and accurate.

  Learn about how Matomo is a serious contender to Google Analytics 360. 

  Now you can import your Google Analytics data directly into your Matomo

  If you’re wanting to make the switch to Matomo but worried about losing all your historic Google Analytics data, you can now import this directly into your Matomo with the Google Analytics Importer tool.

• Easily track Events within Matomo Analytics thanks to Matomo Tag Manager

  Easily track Events within Matomo Analytics thanks to Matomo Tag Manager

  Introduction

  In this article we’ll cover what events in Matomo Analytics are ; and how you can easily set them up thanks to Matomo Tag Manager.

  Key concepts within this article

  • Events
  • Quick definition of the Tag Management System
  • Matomo config
  • Creating triggers
  • Variables

  What are events in Matomo Analytics and why are they useful ?

  Events allow you to measure interactions on your website which are not defined by default. With them you can measure clicks on some elements of a page, such as, how visitors are interacting with dropdown menus, media players, scrolling behaviours etc. You can also use them to define goals which make them a key feature in Matomo Analytics. Learn more about tracking events in Matomo.

  You can easily access the Events report in Matomo Analytics by clicking on the Behaviour category :

  

  And you may read the following message and feel a bit frustrated :

  

  “There is no data for this report” is a nice way to say, “Hey, you are tracking just a tiny part of what Matomo Analytics can do for you.”

  Matomo is a great software, but it can’t guess what you want to track.

  In order for Matomo to register those event tracking interactions, you’ll need to explain it by adding a line of code similar to this one when the interaction happens :

   

  _paq.push(['trackEvent', 'Here you enter whatever you want', 'Here too', 'and here also']);

   

  Let’s imagine you want to track a click on an HTML button, your code will look something similar to this at the moment of the interaction :

  Click Me !

  As you can imagine, two main challenges will arise for non developers :

  1. How to access the source code ?
  2. How to define the interaction ?

  Luckily, Matomo Tag Manager makes those steps easy for you. Let’s see how the same tracking is implemented with Matomo Tag Manager.

  A quick definition of what Matomo Tag Manager is

  Matomo Tag Manager lets you manage all your tracking and marketing tags in one easy-to-access place. Please visit this page to learn more about Matomo Tag Manager. In order to start using it, you’ll need to copy/paste a tracking code, named a “container”, within the section of your pages.

  Once the container is on your website, all you need to do is to follow these simple steps :

  1. Add a Matomo Tag.
  2. Assign the condition to fire the tag (what we call the trigger).
  3. Publish your work.
  4. And enjoy

  1 – Add a Matomo Event tracking code

  All you have to do here is click on “CREATE NEW TAG”

  

  Once selected, just mention how you’d like this tag to be named (it is for your internal purpose here so always use an explicit tag name) and the Matomo configuration (the default configuration setting will be fine in most of the cases) :

  

  Then Matomo Tag Manager will ask you the type of tracking you’d like to deploy, in this case, this is an event so select “Event” :

  

  Then all you need is to indicate the values you’d like to push through your event :

  

  To put it in perspective, all we did here through Matomo Tag Manager was implement the equivalent of the following line of code :

  _paq.push(['trackEvent', 'Element interactions', 'Click button', 'Click Me']);

  Let’s now see how can we do this on click code part which we call a trigger.

  2 – Assign the condition to fire the tag

  In order to execute the event we’ll need to define when it will happen. You do this by clicking on Create a new trigger now :

  

  As the interaction we’d like to track is happening when a click occurs, it will be a click trigger, and as our button is not a link, we’ll select All Elements Click :

  

  Once selected you’ll need to be precise on the condition in which the event will be triggered. In this case we do not want to have events pushed every time someone is clicking on something on our website. We only want to track when they click on this specific button. That’s the reason why our trigger is set to fire only when the click occurs on an element which has an id and has the value “cta” :

  Once you click on the green button named CREATE NEW TRIGGER, you validate the tag by clicking on CREATE NEW TAG :

  

  

  Then you can move to the last part.

  3 – Publish your work

  Tag Managers are very powerful as they allow you to easily execute any JavaScript code, CSS or even text content on your websites.

  That’s why when you create your tag it doesn’t go live straight away on your website. In order to do this you need to publish your tag and this is what the “Publish” category is designed for :

  

  After that, click on the second button if you’re confident your tag and trigger are both ready to go live :

  

  4 – Enjoy

  Well done. As your tag is now live, every click made on this button will now be pushed to your Matomo Analytics account within :
  

  1. The visitor log report :

  

  2. The events report :

  

  You may now be asking, “That’s great, but can I collect something more exciting than clicks ?” 

  Of course you can ! This is what the Matomo Tag Manager is all about.

  As long as you can express it through a trigger you can really push whatever you want to Matomo Analytics. You can track scrolling patterns, an element visible on the page like an image, an ad or the time spent on the page. The options are now open to you with Tag Manager.

  Give them a try ! Change the triggers, start playing around with variables and discover that the possibilities are endless.

  Happy analytics,
