Google up to date their Search Central Documentation to on verifying Googlebot, including documentation about user-triggered bot visits, info that was lacking from earlier Googlebot documentation, which has created confusion for a few years, with some publishers blocking the IP ranges of the professional visits.
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 count on.
These are the three classes of Google Bots:
- Googlebot – Search crawler
- Particular-case crawlers
- Consumer-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:
Instruments and product features the place the top person triggers a fetch.
For instance, Google Website Verifier acts on the request of a person.
As a result of the fetch was requested by a person, these fetchers ignore robots.txt guidelines.”
The documentation states that the reverse DNS masks will present the next area:
Previously, what I used to be advised by some within the search engine optimization neighborhood, is that bot exercise from IP addresses related to GoogleUserContent.com was triggered when a person seen a web site by way of a translate operate that was 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 GoogleUserContent.com will be triggered by the Google Website Verifier instrument.
However Google doesn’t say what else would possibly set off a bot from the GoogleUserContent.com IP addresses.
The opposite change within the documentation is a reference to googleusercontent.com within the context of IP addresses which can be assigned to the area identify, GoogleUserContent.com.
That is the brand new textual content:
“Confirm that the area identify is both googlebot.com, google.com, or googleusercontent.com.”
One other new addition is the next textual content which was expanded from the previous web page:
“Alternatively, you possibly can establish Googlebot by IP deal with by matching the crawler’s IP deal with to the lists of Google crawlers’ and fetchers’ IP ranges:
Particular crawlers like AdsBot
Consumer 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 have been confused by these IP addresses and assumed that these bots have been spam.
A Google Search Console Assist dialogue from 2020 exhibits how confused individuals have 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 person posted:
“The behaviour I see coming from these addresses may be very shut (if not an identical) to professional Googlebot behaviour, and it hits a number of websites of ours.
…If it isn’t – then this appears to point there’s widespread malicious bot exercise by somebody making an attempt fairly arduous to appear like Google on our websites which is regarding.”
After a number of responses the one who began the dialogue concludes that the GoogleUserContent exercise was spam.
“…The Googlebots in query do mimic the official Consumer-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.
