  • Rankings and traffic generating search queries,
  • Page load times and usability,
  • Decline in rankings and organic traffic,
  • Links to your site and with anchor text,
  • Manual penalties or warnings.

The Search Console has its limits, however:

  • Only 16 months of data.
  • The “Links” report is inaccurate. Thanks to years of experience, I now combine third-party tools with Search Console to find everything backlinks.
  • Your site only. Analyzing a competitor’s site requires external (paid) tools.

Google text cache is the easiest way to know how Google interprets a page. The cache displays the text version of a page. Images appear as alt text only. JavaScript and CSS are completely removed. The result is a clutter-free preview of any page, revealing:

  • JavaScript-powered elements inaccessible to Google,
  • Alt text image descriptions that don’t make sense.

Check Google’s cache for any page, yours or a competitor’s, provided the site hasn’t blocked Google’s caching.
