For typical websites, are there any disadvantages to my clients to blocking spiders like Semrush, Maxmind and the plethora of other "non search-engine" bots?
Wouldn't blocking these significantly reduce competitive analysis and provide a cheap net-benefit for my clients? Any ideas why this kind of thing is not a fairly standard service offered by web hosting providers?
Or, put another way, what benefits do Semrush, AHRef and the like give to my clients (assuming they are not clients of Semrush or AHRef)? Do "generic links" created by these sites really help SEO?
(FWIW, this is not a bandwidth thing, and Will blocking bots other than those from the major search engines affect SEO? does not really seem to be quite on point enough)
