When it comes to measuring website performance, pageviews have long been the default metric. They can tell you how many people visited your site, but they reveal very little about whether those visitors actually found what they were looking for.
For publishers, the more valuable insights often lie beyond traffic numbers, the metrics that matter the most are the ones that show how readers are engaging with your books and where opportunities for improvement exist
Add-to-cart rate is one of the clearest indicators of purchase intent. A book page might receive thousands of visits, but very few readers are adding titles to their basket, it's worth investigating why. Is the product page compelling enough? Are reviews and pricing clear? Understanding this helps to identify where interest is failing to convert into action.
Another overlooked metric is search success. Every search a visitor makes is a direct insight into what they’re trying to find. If readers frequently leave after searching, or repeatedly refine their searches, it could point to gaps in your metadata or search functionality. A successful search experience means readers find relevant books quickly and continue their journey.
Speaking of metadata, metadata quality is one of the most influential factors in discoverability. Accurate metadata doesn’t just improve SEO - it powers search, recommendations and filtering across your website.
It’s also worth measuring how readers interact with collections. Whether they’re seasonal reading lists, award winners or staff picks, curated collections help readers discover books they may not have searched for directly. Tracking which collection drives clicks and conversions can reveal what themes and topics resonate with your readers.
Finally, don’t overlook checkout completion. If readers are abandoning their baskets before purchase, small improvements to the checkout experience can have a significant impact on revenue. A streamlined, intuitive checkout is just as important as attracting visitors in the first place.
The most successful publishing websites don’t just measure traffic - they measure progress through the reader journey. By focusing on the metrics that reflect discovery, engagement and conversion, publishers can make smarter decisions that improve user experience and commercial performance.
After all, it’s not about how many people visit your website. It’s about how many readers successfully discover, explore and buy their next book.
