4. Noindex Meta Tag – Accidental use of <meta name=”robots” content=”noindex”> can prevent indexing of your website in google.
5. Blocked in Robots.txt – A misconfigured robots.txt file can stop Google from crawling your site.
6. Frequent Server Downtime – If your website is frequently down, Google may assume it’s inactive.
7. Domain Expired or Removed – If your domain is not renewed or your website is deleted, it will be deindexed.
8. Too Many Redirects – Excessive or incorrect 301/302 redirects can cause Google to drop your pages.
