The API allows users to comprehensively analyze any URL, providing detailed information about its status, redirects, and indexability. When a URL is submitted, the API follows all redirects and returns the final URL along with the corresponding HTTP status code, indicating whether the page responds correctly, has been moved permanently or temporarily, or cannot be found. Each redirect is documented with details of the source URL, status code, and number of hops, providing a complete map of the redirect chain.
In addition to status codes, the API performs multiple checks related to indexability and SEO. These include soft 404 detection, which identifies pages that appear not to exist despite returning a 200 code; reading X-Robots-Tag and meta robots tags to determine if the page allows indexing; checking robots.txt to ensure that bots can crawl the page; and checking for immediate meta refreshes that could affect user experience and indexing. With all this information, the API generates a comprehensive report, clearly indicating whether the page is indexable or not, and pointing out potential issues that could affect its visibility in search engines.
This tool is essential for users who need to automate the analysis of large volumes of URLs, optimize websites, and ensure that content is properly crawled and indexed by search engines. Thanks to its clear structure and detailed information on redirects and indexability checks, the API allows you to make informed decisions about redirects, robot adjustments, meta tags, and other critical technical SEO elements, improving the efficiency and effectiveness of website management.
