About Signal Index
Signal Index is the only free and no sign-up tool which scans your entire website by just its root domain like www.yoursite.com. Unlike other tools, it does not take one or bulk page and post URLs which is extremely time consuming for one to copy and paste and then analyze. At there, this tool stands out.
Just put your website's URL, and within a few seconds, in front of your eyes, live scanning happens. It
scans the whole website, its pages and posts URLs, and sees if there is any no-index signal coming. It
automatically probes header meta tags, HTTP headers (like X-Robots-Tag), general
bot-specific metatags, and robots.txt directives. A comprehensive list arrives with
detailed analysis and reports, which include the URL, its status whether indexable or not, source of
no-index if found (whether from meta tags or robots.txt), and the exact blocked directive.
When scanning is complete, this report can be seamlessly copied to your clipboard or right away saved as a CSV/Excel file for your team or personal auditing records. No hidden limits, no paywalls.
Who Is This Tool For?
