Google has launched a serious revamp of its Crawler documentation, shrinking the primary overview web page and splitting content material into three new, extra targeted pages. Though the changelog downplays the modifications there’s a completely new part and mainly a rewrite of the whole crawler overview web page. The extra pages permits Google to extend the data density of all of the crawler pages and improves topical protection.
What Modified?
Google’s documentation changelog notes two modifications however there’s truly much more.
Listed below are a few of the modifications:
- Added an up to date consumer agent string for the GoogleProducer crawler
- Added content material encoding info
- Added a brand new part about technical properties
The technical properties part incorporates completely new info that didn’t beforehand exist. There aren’t any modifications to the crawler habits, however by creating three topically particular pages Google is ready to add extra info to the crawler overview web page whereas concurrently making it smaller.
That is the brand new details about content material encoding (compression):
“Google’s crawlers and fetchers help the next content material encodings (compressions): gzip, deflate, and Brotli (br). The content material encodings supported by every Google consumer agent is marketed within the Settle for-Encoding header of every request they make. For instance, Settle for-Encoding: gzip, deflate, br.”
There may be further details about crawling over HTTP/1.1 and HTTP/2, plus a press release about their objective being to crawl as many pages as potential with out impacting the web site server.
What Is The Aim Of The Revamp?
The change to the documentation was as a consequence of the truth that the overview web page had turn into giant. Further crawler info would make the overview web page even bigger. A choice was made to interrupt the web page into three subtopics in order that the precise crawler content material might proceed to develop and making room for extra normal info on the overviews web page. Spinning off subtopics into their very own pages is an excellent resolution to the issue of how greatest to serve customers.
That is how the documentation changelog explains the change:
“The documentation grew very lengthy which restricted our potential to increase the content material about our crawlers and user-triggered fetchers.
…Reorganized the documentation for Google’s crawlers and user-triggered fetchers. We additionally added specific notes about what product every crawler impacts, and added a robots.txt snippet for every crawler to display how you can use the consumer agent tokens. There have been no significant modifications to the content material in any other case.”
The changelog downplays the modifications by describing them as a reorganization as a result of the crawler overview is considerably rewritten, along with the creation of three model new pages.
Whereas the content material stays considerably the identical, the division of it into sub-topics makes it simpler for Google so as to add extra content material to the brand new pages with out persevering with to develop the unique web page. The unique web page, known as Overview of Google crawlers and fetchers (consumer brokers), is now actually an outline with extra granular content material moved to standalone pages.
Google revealed three new pages:
- Frequent crawlers
- Particular-case crawlers
- Consumer-triggered fetchers
1. Frequent Crawlers
Because it says on the title, these are widespread crawlers, a few of that are related to GoogleBot, together with the Google-InspectionTool, which makes use of the GoogleBot consumer agent. The entire bots listed on this web page obey the robots.txt guidelines.
These are the documented Google crawlers:

- GoogleOther-Video
- Google-CloudVertexBot
- Google-Prolonged
3. Particular-Case Crawlers
These are crawlers which can be related to particular merchandise and are crawled by settlement with customers of these merchandise and function from IP addresses which can be distinct from the GoogleBot crawler IP addresses.

3. Consumer-Triggered Fetchers
The Consumer-triggered Fetchers web page covers bots which can be activated by consumer request, defined like this:
“Consumer-triggered fetchers are initiated by customers to carry out a fetching operate inside a Google product. For instance, Google Website Verifier acts on a consumer’s request, or a web site hosted on Google Cloud (GCP) has a function that permits the location’s customers to retrieve an exterior RSS feed. As a result of the fetch was requested by a consumer, these fetchers typically ignore robots.txt guidelines. The final technical properties of Google’s crawlers additionally apply to the user-triggered fetchers.”
The documentation covers the next bots:
- Feedfetcher
- Google Writer Middle
- Google Learn Aloud
- Google Website Verifier
Takeaway:
Google’s crawler overview web page grew to become overly complete and presumably much less helpful as a result of individuals don’t all the time want a complete web page, they’re simply enthusiastic about particular info. The overview web page is much less particular but additionally simpler to grasp. It now serves as an entry level the place customers can drill all the way down to extra particular subtopics associated to the three sorts of crawlers.
This variation provides insights into how you can clean up a web page that could be underperforming as a result of it has turn into too complete. Breaking out a complete web page into standalone pages permits the subtopics to deal with particular customers wants and presumably make them extra helpful ought to they rank within the search outcomes.
I’d not say that the change displays something in Google’s algorithm, it solely displays how Google up to date their documentation to make it extra helpful and set it up for including much more info.
