Love the extension, I use it to collect some snapshots when doing CWV competitors analysis for my clients. Super handy, as I can see the full picture in seconds and not wait for the pagespeed test to populate a report.
Really love the extension and the data behind it, and secretly not using it that much for my own website(s), but more so to spy on competitors in the niches of my clients. Not all companies can invest in the fastest websites out there, but now you can show the data about their competitors easily to create a case on why they should, or maybe their competition is even worse so in that case... you don’t have to run faster than the bear to get away. You just have to run faster than the guy next to you ;-)
Easy to check what the performance of a website is
I've actually created the pagespeed history tool, and so far I used a bookmark to jump to the historic results of a visited domain. But I typically have my bookmarks bar hidden, so an extension is way more convenient (for me, but also easier for others to install). So, thanks for creating this Jordy! I linked to this extension from the results page as well :D
As someone deeply invested in the e-commerce space, I've always recognized the crucial role that page speed and user experience play in the success of online businesses. Discovering RUMvision's Google Chrome extension, "Historic Core Web Vitals," was a turning point for me. This innovative tool effortlessly provides a historical view of the core web vitals for any domain, making it incredibly easy to analyze and optimize website performance over time. What sets this extension apart is its simplicity and effectiveness. With just a few clicks, I can view a comprehensive history of a website's core web vitals. This includes key metrics like Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS), which are crucial for understanding how users experience a website. The insights I've gained from using Historic Core Web Vitals have been invaluable. Not only does it help in pinpointing areas that need improvement, but it also allows for a strategic approach to enhancing overall website performance. The historical data aspect is particularly useful for tracking progress and understanding the impact of changes made to the site. Moreover, RUMvision's commitment to enhancing the e-commerce experience is evident in this tool. They are truly rocking the world of page speed by providing such a handy and insightful tool. It's clear that their contribution to the e-commerce space is significant, and their expertise shines through in the functionality and reliability of this extension.
