Many of the older posts that ranked in the top 3 (1st page) on Google are either on the second page or at best floating around the last result on the first page. The results on Yahoo are even worse. According to information on Market Samurai, Yahoo hasn't re-indexed my blog with the new (original) permalink structure and most of the posts that used to rank 1 to 3 are not even found. Traffic has more than halved and I feel that my work for the past 2 years have gone to waste.
I guess what I'm trying to ask is, will my blog ever regain the ranking in the serp? I changed the permalink structure to the original setting again because of the backlinks pointing to the inner pages, but now I'm wondering if I should have just left it as it was changed. Has anyone experienced something similar or know what I should expect after a mistake like this? Thank you for taking the time to read this and please share any opinion you may have on this.
