How about;

1) SEO 2006 = certain keyword density and placement to bring you right up to but not over the line. Maybe even linking / architecture strategies too.

2) Google thinks "Hmmmm, certain areas are full of SEO's.

3) Google moves the line for some search terms in 2007.

I am pretty sure it is keyword density / architecture not site (domain) though. I have one site, two main parts (in two competitive search areas known to attract Google's attention). One part I decide to change the format a little to bring certain pages closer to the section root (I would say index but the index page of both my domain and section are not as highly ranked as a certain page on each which people naturally link to); I did this to overcome a problem with Google last year! Now search term 2 shows section 1 (it looks kind of odd in the search returns so I had to change section 1's page a little and put a link "Click here for Section 2" right at the top of the main page for section 1. BTW, section 1 also ranks #1 for search term 1. Section 2 used to rank at #1 for search term 2, but now section 1 does and section 2 is not even shown!

It is like I have a widgets site with two sections, ship widgets and house widgets (I used this differentiation as I think blue and red widgets does not show the huge gap between the two sections well enough). Now someone searching for "house widgets" gets "Don't let your boat sink, get your boat widgets here" in the Google SERPs.

I thought putting the link to section 2 at the top of main page section 1 might actually hold the key to having the more logical and prefered search results return in Google, but it did not. Shortly I will have to redo the site architevcture for section 2 again as clearly this is the issue. BTW, it is actually a non-profit site.
