I have a doctors medical site 13 years old but never SEO until last 3 months. Last month and a half hit bottom or top of page 1 or top of page 2 for 2 highly competitive keywords and a few other keywords hit page 2 or 3 , not bad for 1 1/2 months of SEO. Now in the last week all have gone or have fallen a lot. I mostly used linkpush and MR ME blog network, both which had wonderful results while it lasted. Ive done some bookmarking and used , forgot the name of the service, to scrapebox and bookmark all the backlinks. Now I believe most keywords had already dropped before I scrapboxed the backlinks. since this site had very little backlinks but very aged, and I just started doing SEO recently could this drop in keyword rank be most likely due to google dance ?
