Resolve Google Crawl Errors Magento

During the past three weeks Google Search Console has shown a dramatic drop in crawl rate on my Magento 2 store. The coverage report lists roughly 35 % “not crawled” every single day.

I have already checked Google Search Console and reviewed the raw server logs, yet the root cause is still unclear. I need someone who has deep experience with Magento 2, server-side debugging (Apache/Nginx, PHP-FPM, MySQL) and Google Search Console diagnostics to uncover what is blocking Googlebot and correct it quickly.

What I expect from you
• Analyse server configuration, response codes, robots.txt, sitemap and crawl budget in relation to Magento 2.
• Identify why URLs trigger “High crawl errors” and produce the “not crawled / not called” pattern.
• Implement the necessary fixes—whether that involves rewriting rules, cache or Varnish settings, cron, canonical tags, or code patches—directly on the staging site and then push to production.
• Provide a concise report outlining the root cause, actions taken, and verification steps in Search Console.

Once the crawl rate returns to normal and errors clear in Search Console, the project is complete.
