Hi @massimod for Related Content to work, Shareaholic needs to index your content so the recommendation engine knows what to recommend. This actually increases performance, as all the processing (complex math) then happens on our servers vs. bogging down yours and your databases.
How does Shareaholicbot access sites?
We do very aggressive caching so you shouldn’t see Shareaholicbot in your logs more than once every few weeks for any one URL. Our goal is to crawl as many pages from your site as we can on each visit without overwhelming your server’s bandwidth. We don’t like waste either, and are clever at not wasting bandwidth – yours or ours. However, if you experience technical issues, please contact us at [email protected]. We recommend attaching any relevant server logs that may help.
