my niche is changing drastically from the #5 position on down. was in the #11 spot for months...this weekend shot up to 6th then to 12 now at #16. trying to analyize what is going on...what it seems is that sites that have fresh content are getting hammered, while those that have not been updated recently (one hasn't added pages or content since 1998) are holding position. Very strange...something is in the works for sure. My niche never changes, even thru allegra and florida.
the way this is going i will probably post tommorrow that i have fallen out of the G serps.
1/2 of my pages went url-only over the last couple of days. Few pages have any content in common except for nav bars. This morning 20% of pages completely missing from index. All pages are paragraph-style with 300-1000 words per page.
