What is this all about? I found out by googling an innocuous word. Is it algorithm stuff rather than any human agency?

Sounds like paranoia to me, but maybe it’s something real.  I’ll be curious to see if anybody knows.

It may be just repeated content, not any animus against the Online Slang Dictionary. There are lots of spam/SEO cites that attempt to regurgitate content from high-scoring sites in an attempt to gain more traffic. It may be that the Google algorithm has some criteria for a ratio of original to quoted content.

Dave’s exactly right.

The site is poorly structured from an SEO point of view. The polls are simply pictures as far as Google is concerned, the ads eat up a lot of space, the “tweets that contain” plugin is auto-generated content (something Google particularly dislikes) and frankly, unless you have definitions that no one else has, then you’re simply in a battle of the PageRank to see who gets the better SERPs.

Bottom line: the guy’s in a tough market and he needs to compete more effectively.

People love to whine about Panda. It happened, it’s the new order, get over it. Build a better site.
