What is GoogleProducer? Google's on-request crawler

GoogleProducer is Google Publisher Center's fetcher: it fetches and processes the feeds publishers supply for their Google News landing pages.

2%of 1662 major websites block GoogleProducer — 35 blocked, 1527 allowed, 100 with no matching rule

35 of the 1662 major websites we measure block GoogleProducer in robots.txt (2%). 2 of those sites name it directly in their robots.txt; the rest are covered by a wildcard rule.

What blocking GoogleProducer does

Google says user-triggered fetchers generally ignore robots.txt rules, because a person asked for the fetch. The figures below show what files state, not what this fetcher does.

How to allow or block GoogleProducer

Add one of these groups to the robots.txt file at the root of your domain. It is a stated preference that well-behaved crawlers read, not an enforcement mechanism.

BLOCK
User-agent: GoogleProducer
Disallow: /
ALLOW
User-agent: GoogleProducer
Allow: /

GoogleProducer user agent string

Google's page doesn't list a full string, so look for GoogleProducer in the user agent field of your logs.

How to verify a request is really GoogleProducer

Anyone can put a crawler's name in a user agent string, so the name alone proves nothing. We did not find a published IP list or reverse DNS rule from Google.

How to whitelist GoogleProducer in a firewall or CDN

robots.txt only states a preference. A firewall, CDN or bot protection service can still refuse the request, and the crawler then gets an error even though robots.txt allows it.

  1. Check that no group in your robots.txt blocks it, using the rule above.
  2. Add an allow rule in your firewall or CDN that matches the name in the user agent. Keep the rule narrow, because anyone can copy a name.
  3. Check your server logs for a 200 response from GoogleProducer afterwards.

On Cloudflare, also check AI Crawler and Agent access policies, which can block search, agent and training traffic across a site.

Why GoogleProducer gets a 403 or 405 error

A 403 means the server refused the request, which usually points to a firewall or bot rule. A 405 means the server refused the request's method, so check any rule that only permits certain methods. A crawler that obeys robots.txt won't request a page it is told to avoid, so an error in your logs points to your server's configuration. To stop it deliberately at the server, this nginx rule returns a 403:

NGINX
if ($http_user_agent ~* "GoogleProducer") {
    return 403;
}
