In any case, I've noticed a heartening trend lately. Ever since I've been sharing my Weebly blog posts on Google Plus they seem to end up in search results much quicker than before.
This might not be the actual cause, of course. Perhaps it's because I've been posting more frequently and have "trained" the search engine spiders to be quicker off the mark! Or perhaps this is a general phenomenon related to all Weebly blogs ...
Still, I think my hunch is correct. If it is then it's yet another good reason to join Google Plus and share blog posts, particularly if they are topical in nature and benefit from quick indexing.
