Key Points

  • Most “large HTML size” warnings in Semrush are harmless and can’t be fixed on hosted platforms like Squarespace or Wix.

  • WordPress sites can accumulate excessive HTML from too many plugins.

  • Deactivate and test unnecessary plugins before deleting them to avoid breaking your site.

  • Reducing plugins helps improve site speed, which can slightly boost SEO rankings.

Summary

This video describes what it means when your Semrush audit flags pages for having “too large HTML size” and when you actually need to take action. In most cases, you don’t need to worry about this issue, as it’s largely outdated and caused by modern website platforms generating naturally large amounts of code. The only time you should investigate is if you use WordPress with many plugins, since those can slow your site and impact SEO.
