Newly Up to date Bot Documentation

Google added a brand new documentation that categorizes the three totally different sorts of bots that publishers ought to anticipate.

These are the three classes of Google Bots:

  • Googlebot – Search crawler
  • Particular-case crawlers
  • Person-triggered fetchers (GoogleUserContent)

That final one, GoogleUserContent is one which’s confused publishers for a very long time as a result of Google didn’t have any documentation about it.

That is what Google says about GoogleUserContent:

“Person-triggered fetchers

Instruments and product features the place the tip consumer triggers a fetch.

For instance, Google Website Verifier acts on the request of a consumer.

As a result of the fetch was requested by a consumer, these fetchers ignore robots.txt guidelines.”

The documentation states that the reverse DNS masks will present the next area:


Up to now, what I used to be informed by some within the search engine marketing group, is that bot exercise from IP addresses related to was triggered when a consumer considered a web site by a translate perform that was once within the search outcomes, a function that not exists in Google’s SERPs.

I don’t know if that’s true or not. It was sufficient to know that it was a go to from Google, triggered by customers.

Google’s new documentation explains that bot exercise from IP addresses related to will be triggered by the Google Website Verifier instrument.

However Google doesn’t say what else may set off a bot from the IP addresses.

The opposite change within the documentation is a reference to within the context of IP addresses which can be assigned to the area title,

That is the brand new textual content:

“Confirm that the area title is both,, or”

One other new addition is the next textual content which was expanded from the previous web page:

Particular crawlers like AdsBot

Person triggered fetches”

Google Bot Identification Documentation

The brand new documentation lastly has one thing about bots that use IP addresses which can be related to GoogleUserContent.

Search Entrepreneurs had been confused by these IP addresses and assumed that these bots had been spam.

A Google Search Console Assist dialogue from 2020 exhibits how confused individuals had been about exercise related to GoogleUserContent.

Many in that dialogue rightly concluded that it was not Googlebot however then mistakenly concluded that it was a faux bot pretending to be Google.

A consumer posted:

“The behaviour I see coming from these addresses may be very shut (if not similar) to authentic Googlebot behaviour, and it hits a number of websites of ours.

…If it isn’t – then this appears to point there may be widespread malicious bot exercise by somebody making an attempt fairly exhausting to appear like Google on our websites which is regarding.”

After a number of responses the one that began the dialogue concludes that the GoogleUserContent exercise was spam.

They wrote:

“…The Googlebots in query do mimic the official Person-Brokers, however because it stands the proof appears to level to them being faux.

I’ll block them for now.”

Now we all know that bot exercise from IPs related to GoogleUserContent will not be spam or hacker bots.

They are surely from Google. Publishers who’re presently blocking IP addresses related to GoogleUserContent ought to in all probability unblock them.
