How to use this tool
1. Paste HTML or URL
Enter a live web page URL or paste your HTML `<head>` markup for instant evaluation.
2. Inspect Directives
Verify the presence and combination of index/noindex, follow/nofollow, and snippet controls.
3. Check Robots.txt Conflicts
Confirm that noindexed pages are not blocked in robots.txt (which prevents Google from seeing the noindex tag).
4. Generate Clean Meta Tags
Copy validated `<meta name="robots">` code ready to insert into your Next.js or WordPress template.
Formula or logic used
Robots Directives Precedence & Evaluation Rules
Search engines evaluate robots directives using strict precedence rules: the most restrictive directive always wins.
Negative Precedence: If one tag specifies `index` and another specifies `noindex`, `noindex` wins.X-Robots-Tag vs Meta Tag: Both are equally respected; conflicting directives resolve to the most restrictive.Crawl Prerequisite: A page blocked by robots.txt CANNOT have its `<meta name="robots" content="noindex">` tag read by Google.Modern Directives: `max-snippet:-1`, `max-image-preview:large`, `max-video-preview:-1` enable rich snippets and Google Discover eligibility.
Examples
Example 1: Standard Modern Indexable Page
The recommended meta robots tag for high-ranking marketing, blog, and product pages.
Example 2: Contradictory Staging Bug
Common developer error where a staging noindex tag leaked into the production build.
Common use cases
Post-Launch Staging De-indexing Audit
Verify that all production pages had their staging `noindex` tags removed before launch.
Google Discover Optimization
Ensure `max-image-preview:large` is active so high-resolution cards appear in mobile feeds.
Private PDF & Document Protection
Deploy `X-Robots-Tag: noindex` HTTP headers to prevent non-HTML files from ranking in search.
Affiliate & Paid Link Hygiene
Verify that sponsored or untrusted outbound links include appropriate `rel="nofollow"` or `rel="sponsored"`.

Frequently asked questions
What happens if a page has both index and noindex tags?
The most restrictive directive always takes precedence. In this scenario, Google will treat the page as `noindex` and remove it from search results.
Why can't I block a noindexed page in robots.txt?
If you block a page in robots.txt, search engine crawlers will never fetch the page HTML. Therefore, they will never see the `<meta name="robots" content="noindex">` tag, and the page may still appear in search results if other sites link to it.
What does max-image-preview:large do for SEO?
The `max-image-preview:large` directive explicitly grants Google permission to display large, high-resolution thumbnail images in search results and Google Discover, dramatically increasing click-through rates (CTR).
What is the difference between meta robots and X-Robots-Tag?
The `<meta name="robots">` tag is an HTML element placed inside the `<head>` of a web page. The `X-Robots-Tag` is an HTTP header sent by the web server, which can be applied to non-HTML assets like PDFs, images, and video files.
