In Google search console I see a number of searches by Google bot. In below article, the author makes an argument for using robots.txt to block certain Googlebot searches
The bulk of that article deals with faceted searches. That’s not my issue, I just have Googlebot using onsite search. Should I block that type of behavior by Googlebot?
Googlebot is the web crawler used by Google to discover and index web pages, including search pages. Allowing Googlebot to crawl your search page can help ensure that your content gets properly indexed and appears in relevant search results.
