# FeedFetcher-Google

> Crawls RSS and Atom feeds for Google News and WebSub. It is a user-triggered fetcher, and Google documents that those generally ignore robots.txt because a person asked for the fetch. Google publishes fetcher addresses in two files — user-triggered-fetchers.json and user-triggered-fetchers-google.json — and does not say per fetcher which one applies, so verification means checking both; this index mirrors both.

## What blocking it costs you

Feed-driven Google products stop seeing your updates. A robots.txt rule will not stop it — block by user-agent at the edge if you mean it.
