I managed to rank one of my pages from 40-50th position on SERP to 10-11th however I don't see ANY traffic increase. In fact I was getting more traffic when the page was sitting on 40-50. The page ranks for 1 primary keyword, singular has G estimated volume 40,000 and plural 6,000. I have other pages ranking like 15, 17, 20 that are getting way more traffic with lower estimated volume than the one on 11th. I keep asking myself if this is normal or am I missing something. Has any of you had similar experience ? P.S. I checked the ranking using 3 different services so they are accurate.
