## About

## What it does
SEO Toolkit gives you a small set of endpoints for generating and checking common on-page SEO assets. Send page content, site details, or target keywords, and get back the tags, markup, or text statistics you need to wire into your product.

Use SEO Toolkit to generate meta tags from a page title and description, build schema.org JSON-LD for an article, FAQ, or organization, and create robots.txt plus sitemap.xml from a domain and a list of paths. It also includes a keyword density checker that returns total word count, keyword count, density percentage, and the positions where the keyword appears.

If you need social or content workflows, you can extract or generate hashtags from text or keywords. The meta tags endpoint returns ready-to-paste HTML plus the same tags as key-value pairs, so you can drop the output directly into a page head or preview it before publishing.

This is a good fit for CMS integrations, publishing pipelines, internal SEO tools, and automated site audits where you want structured output without hand-crafting every file or tag.
