After Google penguin update i found some of my website's keyword lost ranking. I checked all the inbound backlinks of my website and all anchor texts. I noted two or three keywords has been getting backlink from a particular blogspot.
Now I plan to remove those backlinks, but if I do that i would lose more than 1000 backlinks. Does decreasing backlink would affect all my keyword's ranking in Google? or would it affect only those two or three keywords? Overall backlink count according to GWT is 18,403 (it may varied on other SEO online tools).
