Google is a cranky sob
 

I have like 3 sites running separately from one domain (domain.com, domain.com/site, domain.com/othersite, etc) with different trades and all.

On one of the sites I decided to push the majority of the traffic to the trade sending the most sales instead of the one sending the most productivity back. Google didn't like that and decided to yank 98% of search engine traffic to all three sites LOL.

Hopefully changing it back will fix things, usually does..

Yikes! SEO can be tricky, that's for sure.

Google is like a woman - with the power to bring great pleasure or make your life miserable, with no regard for logic whatsoever.
