When you operate commercial sites at scale, bots are a real thing you spend real engineering hours thinking about and troubleshooting and coding to solve for.
And yes, that means google gets special treatment.
Think about the model for a site like stackoverflow. The longest of long tail questions on that site: what’s the actual lifecycle of that question?
- posted by a random user
- scraped by google, bing, et al
- visited by someone who clicked on a search result on google
- eventually, answered
- hopefully, reindexed by google, bing et al
- maybe never visited again because the answer now shows up on the google SERP
In the lifetime of that question how many times is it accessed by a human, compared to the number of times it’s requested and rerequested by an indexing bot?
What would be the impact on your site of three more bots as persistent as google bot? Why should you bother with their requests?
So yes, sites care about bot traffic and they care about google in particular.
