My server handles my visitors ok, but recently I found there are many search engine bots crawling my site and my server gets quite busy serving these bots.
My site generates over 1000 posts each day, so it might be normal for the bots crawling my site often.
However, is it possible to decrease the frequency for the bots crawling my site? Or just tell the bots to craw my new posts? It seems they are crawling my site more and more often and my server becomes slow when they visit my site.
