A few days ago I linked to a local site that I own with a few high PR blog posts. Nothing excessive. The posts were readable and I also linked to a few authorities in the posts too. A few of these posts are actually showing on page 1-3 and have live links to my site's page. My site stayed around position #3 for a few days and then dropped way down into the 400's. I've been doing SEO for awhile now and this is a little strange for a few reasons: A) New content on my site isn't being indexed. I posted an original article on my site when I saw this happen and it hasn't indexed in over 48 hours. After posting it, I social bookmarked it with imautomator to help it index. B) 400+ for my site is really weird. I've had sites dance down to 100-200+, but never as far as 400. C) The page indexed for that keyword at position 400+ is my root domain. It's the non-www version even though I have wordpress set to www. So is this some type of penalty? Or is this a different type of Google dance that I've never seen before? PS: This is a biggie that I was stupid not to add above. A day or so after I noticed that might site jumped to pos #3, I changed my meta description slightly. I included an lsi keyword. So now that I remember doing that, it could have potentially forced Google to reanalyze my site and decide to reindex it.
