Documentation

Vantage SEO is an SEO plugin for the Instatic static-HTML CMS. These pages tell you how to install it, how to set it up, and how to check what it writes into your site.

What Vantage SEO does

Vantage SEO writes titles, meta descriptions, Open Graph tags, schema.org JSON-LD and site verification tags into your pages. It does this when Instatic publishes a page, so the tags are part of the static HTML file. No SEO code runs on the server when a visitor opens a page.

The plugin also serves an XML sitemap and an llms.txt file, and it tells search engines about changed pages through IndexNow. In the page editor, an SEO panel shows a search result preview and a content analysis while you write.

The free edition is open source under the MIT license. The Pro edition adds an MCP server for AI agents, a redirect manager, a scheduled site audit, Google Search Console data, a schema builder and an AI assistant that uses your own API key. Both editions use the plugin id monkeywebs.seo, so an upgrade keeps your data.
