The seo4ajax bot is used by a service that helps make single-page applications (SPAs) crawlable by search engines. It pre-renders JavaScript-heavy pages into static HTML so they can be indexed.

How Centinel checks it

User agent: The request calls itself this crawler. Anyone can send the same string.

seo4ajax publishes nothing Centinel can check a source against, so a match reports the name and leaves the source unconfirmed. The match tokens, verification domains, and address feeds are not published here.

Allowing or blocking it

The crawler object in the /validate response sets access_allowed to true only for a verified source that your tenant allowlists. A policy rule can allow or block this crawler by its category, SEO Tool.
