Content Tracking is a feature unique to Matomo that we built to determine the performance of the pieces of content on any page of the website or app. You might be wondering how often a specific ad or a banner was displayed and viewed by your visitors on any of your pages and how often a visitor actually interacted with them. We call these two parts content impression and content interaction.
This feature is not only limited to ads or banners. You can use it for any kind of content. Once a page has loaded we log a content impression for each content block that is visible to the user. A content block consists of a content name (My Product 1), a content piece ("product1.jpg" or "Buy Product 1 now") and a content target (http://landingpage.example.com). As soon as a visitor clicks on a content block a content interaction is logged allowing you to analyze the ratio of content impressions to content interactions. As soon as a visitor scrolls down the page and sees more ads/banners/blocks, we automatically log the impression for each block.
