What is wrong
Some of your pages have HTML documents larger than 1024 kilobytes. An HTML document is the raw code that makes up a page; it should mostly contain text and structure, not images or video.
Why it costs you
Large HTML files slow down the initial load of your pages because browsers must download and process the entire file before they can start displaying anything to your visitor. This delay is especially noticeable on mobile devices and slower connections, which means some visitors may leave before the page even appears.
How to fix it
Check which pages are affected by looking at the file size reported in your audit tool. If a page is bloated with HTML, the cause is usually one of these: too much embedded data (such as JSON or configuration code in the page itself), a poorly designed template that duplicates code on every page, or content management system bloat. Work with your developer to move data out of the HTML into separate files, simplify your page templates, or audit your CMS plugins to see if any are injecting unnecessary code into every page.
What the audit tests
- The HTML document is no larger than 500KB
