Google up to date its Search Central documentation to confirm Googlebot and added documentation about user-driven bot visits, data that was lacking from earlier Googlebot documentation, which triggered confusion for a few years as some publishers used the IP -Blocked areas of reliable visits.

Newly up to date bot documentation

Google added new documentation categorizing the three several types of bots publishers ought to count on.

These are the three classes of Google Bots:

• Googlebot – search crawler
• Particular case crawler
• Person-triggered retrieval packages (GoogleUserContent)

The latter, GoogleUserContent, has lengthy confused publishers as a result of Google did not have documentation about it.

That is what Google says about GoogleUserContent:

“Person-triggered polling packages

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

For instance, Google Web site Verifier acts on a consumer’s request.

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

The documentation states that the reverse DNS masks reveals the next area:

“***-***-***-***.gae.googleusercontent.com”

Prior to now, I have been informed by some within the search engine optimisation neighborhood that when a consumer seen a website via a translation function that was included in search outcomes, bot exercise was triggered from IP addresses related to GoogleUserContent.com was, a function that not exists in Google’s SERPs.

I do not know if that is 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 may be triggered by the Google Web site Verifier device.

However Google does not say what else may set off a bot from GoogleUserContent.com’s IP addresses.

The opposite change in documentation is a reference to googleusercontent.com within the context of IP addresses related to the area title GoogleUserContent.com.

That is the brand new textual content:

“Make sure that the area title is both googlebot.com, google.com, or googleusercontent.com.”

The next textual content has additionally been added, which has been expanded in comparison with the outdated web page:

“Alternatively, you’ll be able to determine Googlebot by IP handle by matching the crawler’s IP handle to Google’s lists of crawler and fetcher IP ranges:

Googlebot

Particular crawlers like AdsBot

Person-triggered fetches”

Documentation for figuring out Google bots

The brand new documentation lastly has one thing about bots utilizing IP addresses related to GoogleUserContent.

Search engine entrepreneurs had been confused by these IP addresses and assumed these bots had been spam.

A 2020 Google Search Console Assist dialogue reveals how confused individuals had been about Google UserContent-related exercise.

Many on this dialogue appropriately concluded that it wasn’t a Googlebot, however then incorrectly concluded that it was a faux bot pretending to be Google.

A consumer posted:

“The habits I am seeing from these addresses could be very shut (if not similar) to reliable Googlebot habits and impacts a number of of our web sites.

…If not, then this appears to point that there’s widespread malicious bot exercise by somebody attempting very exhausting to appear like Google on our web sites, which is worrying.”

After a number of replies, the one who began the dialogue concludes that the GoogleUserContent exercise was spam.

They write:

“…The Googlebots in query mimic the official user-agents, however because it stands the proof appears to point that they’re faux.

I am going to block them for now.”

Now we all know that bot exercise from IPs related to GoogleUserContent usually are not spamming or hacking bots.

They are surely from Google. Publishers at the moment blocking IP addresses related to GoogleUserContent ought to in all probability unblock them.

The present listing of consumer triggered fetch IP addresses is obtainable right here.
