SEOCore

An enterprise-grade, multi-threaded SEO crawler, rule engine and link graph analyzer built in TypeScript for site health audits. It combines a concurrent crawler, Cheerio-based scrapers and a declarative rule engine, and it computes authority scores in the style of PageRank across internal links. Audits cover on-page AI readiness, including content extractability, entity clarity and citation readiness, AI and LLM crawler access directives for GPTBot, ClaudeBot, PerplexityBot and Google-Extended, llms.txt rules, mobile usability, E-E-A-T pillars and readability scores such as Flesch Reading Ease. A backlink and Google rank checker reports referring domains and inbound links from your own sources: a Search Console export, server access logs or similar. Local checks include NAP consistency across citation sources. Single-aspect probes cover robots, sitemap, schema, hreflang and screenshots. Results export as JSON and HTML for CI/CD. MIT licensed.
