# SEO for SaaS

> SEO for SaaS researches, writes, and cites SEO articles for SaaS products and delivers them to your site as typed JSON blocks over a read-only API, with a webhook when an article changes.

Every page below is Markdown. The example article (one of every block type) needs no key:
https://api.seoforsaas.dev/public/v1/fixtures/article · block schema: https://api.seoforsaas.dev/public/v1/schema/blocks.json
