I noticed one thing while I was browsing through one to other page of google while searching for one of my keyword. On page 1 Google shown 362,000 competition, while on Page 3 It shown 2,213,000 competition. I could not understand what does that mean. In general for any keyword there should be only one competition figure, which we take in consideration and then work hard to get our site listed in top ranking but if there are varied competition figures on different pages, which one we consider is correct?
