We're excited to announce that we've launched Last Painted Hero as an official metric. Last Painted Hero is a synthetic metric that shows you when the last piece of critical content is painted. We call those parts of the page the "hero elements". The case for smarter heuristics.

In this correlation chart, you can see that conversion rate peaks at just over 6% for sessions with Largest Contentful Paint (LCP) times of 1.1 For example, depending on how you've built your page, Largest Contentful Paint can measure elements like the cookie consent banner, not your main image. Learn more about LCP caveats.)

First Meaningful Paint. Over the last seven years, the number of scripts jumped from 12 to 36 and the compressed size increased from 110K to 617K for the world's top 1000 websites according to the HTTP Archive.

That's because video seems to have had a surge in growth, which should be a cause of concern for anyone who cares about metrics like Largest Contentful Paint, which measures the largest visual element on a page – including videos.

That's why it's a good idea to not just focus on metrics like Start Render – you should also investigate Hero Rendering metrics , which track when the most meaningful content on your pages (e.g., hero images, headlines) renders. Last Painted Hero (synthetic): 5 seconds recommended. Create performance budgets.

Last time, I navigated the web for a day using Internet Explorer 8. Throughout the experiment I will suggest performance tips to speed up the first contentful paint and perceived loading time of the page. How about the hero image? A JPEG image needs to be decoded, rasterized, and painted on the screen. MB of images?
