Technical SEO

JavaScript SEO Dependency Audit Inspect which important SEO signals exist in server HTML and identify structures that are likely to depend on JavaScript, without an external browser service. Redirect Chain and HTTP Status Checker Trace every allowed HTTP redirect step and identify loops, long chains, temporary redirects and an unexpected final destination. Faceted Navigation Analyzer Inspect a local URL sample for reordered parameters, tracking or session fields and transparent evidence of combinatorial crawl growth. URL Migration Map Validator Validate a local old-to-new URL map for duplicates, conflicts, self redirects, chains, cycles and host or scheme migration risks. XML Sitemap Validator Check an XML sitemap or sitemap index for structure, absolute locations, duplicates, host scope and valid lastmod values. XML Sitemap Generator Crawl a limited sample of public same-origin pages and create a valid XML sitemap without inventing lastmod dates or promising indexing. Robots.txt Generator Create a robots.txt file with current crawler presets, Allow and Disallow rules and sitemap locations, with an explanation of each directive. URL Rewrite Rule Generator Prepare reviewable rewrite examples for clean URL paths, together with redirect and canonical checks to complete before deployment. Content Freshness and Indexability Checker Review Last-Modified, ETag, robots directives, canonical, sitemap lastmod and page dates after the retirement of Google Cache. IndexNow Package Preparation Validate up to 100 same-host URLs and prepare a redacted JSON package with clear manual submission steps, without an automatic request to IndexNow. Search Crawler View Inspect the metadata, headings, visible text and links available in server-rendered HTML without claiming to reproduce a specific search engine. HTML Source Viewer Inspect an escaped, size-limited HTML response from a public page, together with its status, content type and final URL. WWW Redirect Checker Trace the HTTP path between www and non-www variants and confirm that it reaches the chosen final HTTPS address without an unnecessary chain. Indexability and Discoverability Check Inspect HTTP, robots.txt, meta and X-Robots-Tag directives, canonical and sitemap evidence, then open a separate manual search. Technical and On-Page SEO Audit Run an explainable page audit across HTTP, indexability, metadata, headings, links, images, structured data and security signals. Semantic and Agent Navigation Audit Inspect server HTML landmarks, genuine links and buttons, form labels, accessible action names and stable navigation content with concrete evidence. Robots.txt and Indexability Tester Check robots.txt, meta robots, X-Robots-Tag, HTTP status and canonical signals together for a specific public URL.
