Check the site's noindex/nofollow
Tan Phat Digital's free online robots meta tag checker tool helps detect important directives that affect SEO: noindex (block page indexing), nofollow (block follow links), noarchive (block cache), nosnippet (block snippet), noimageindex (block image index). Fetch and parse the HTML of any URL. Displays the raw content of the meta robots tag. Intuitive status with green/red icons for each directive. Explain the meaning of each directive in Vietnamese. Warning when robots meta tag is not found. Useful for SEO specialists, web developers, and content managers to audit and debug indexing issues.
Robots meta tag is one of the most important factors that determine whether a website is indexed by Google or not. A small mistake can have serious consequences: Accidentally adding noindex causes the page to completely disappear from Google. nofollow on internal links loses link equity and affects rankings. nosnippet makes the page appear less attractive in search results. noarchive prevents users from viewing the cached version when the site is down. Situations to check: After website migration or redesign. When important pages don't appear on Google. Debug indexing issues in Google Search Console. Audit technical SEO for clients or competitors. Check the staging site before going live (staging usually has noindex). Verify after removing noindex to re-index. This tool helps check quickly and accurately, without needing to manually view the source.
