However I didn't expect this.
One of my sites - usually gets around 15-20 uniques/day, has been completed knocked out for all it's keywords. It's still indexed, there are still around 140 pages indexed, but it doesn't rank. At all. I WAS getting loads of longtail traffic from indexed tags on my posts, but not any more.
This blog was set up to drip feed content daily (at different times). The content was always about a paragraph of text, plus an image, and link to Amazon. the copy was always original and well written, plus there are 3 other static pages on the site which consists of around 2000 original words.
It really bugs me that Google has probably deemed this an "auto blog" because it drip feeds small amounts of content which links to an affiliate page on a daily basis.
What am I going to do about this? for a start I'm going to keep adding content, I might expand my words a little, and I'm also going to steadily backlink to the sites inner pages. Hoping this makes Google turn around and wake up, and stop giving me such a hard time.
