My sites, like everyone’s nowadays gets allot of referral spam, usually I just ignore it, but recently I've been getting organic traffic spam where they use their website URL as the search phrase. The issue with this is that its skewing my bounce rate and thus effecting site ranking.
To get around this I've been reading up on the best ways to block referral and organic spam and most people tend to suggest setting up a filter of known spam URLs, but i recently came across THIS ARTICLE which talks about setting 'bot filtering' to true (bot filtering automatically runs refers against a IAB list of known spam and malicious bots). Ive implemented this in another Google Analytics view so i can see the difference before and after I made this change.
If it 'bot filtering' does what it says it does why isn't it turned on by default? Is there some downside to it?
