I have loads of traffic from SEO analysis bots (which are crawling for link analysis purpose only, rather than indexing for search engines) such as
AhrefsBot/7.0; +http://ahrefs.com/robot/
SemrushBot/7~bl; +http://www.semrush.com/bot.html
Neevabot/1.0; +https://neeva.com/neevabot
I don't use their services, and thus, it has no use for me to be included in their system.
Does crawling by those bots have any benefit to my website popularity or should I block them to save unnecessary traffic?
