SEO Tools API

A NestJS API that collects SEO tools for webmasters, developers and SEO professionals into separate modules. Modules include a backlink checker, a rank checker that checks search engine rankings for specified keywords, an SEO audit, a sitemap generator, competitor analysis with insights into backlinks, keywords and rankings, a page speed analyzer that reports page size, load time and requests with recommendations, content optimization that analyzes page content and gives suggestions, and internal linking analysis. Endpoints such as /backlink-checker and /rank-checker are served locally, and interactive documentation is available through Swagger. Installation uses npm and a development start command. It suits developers who want to embed SEO checks in their own tools through HTTP. Each module sits behind its own route, so a developer can call only the pieces needed.
