Per-Page SEO Checks

Critical Priority (High Impact on SEO)

1. Title Tag Check

  • How it checks: Looks for missing or empty title tags in the HTML <title> element, or checks SEO plugin meta data
  • Priority: High
  • Why important: The title tag is one of the most important on-page SEO factors. It appears in search results and helps search engines understand what the page is about. Missing or poorly optimized titles significantly hurt rankings.

lkoudal / search_templates
Created October 7, 2021 20:31 — forked from bobpoekert/search_templates
A machine readable list of search engines. Each line is a query template, where all occurrences of {searchTerms} should be replaced with the search query. These were scraped off mycroft.mozdev.org, and tested that they at least respond with a page that contains the input query (to remove pages that lie behind login walls).
