How do the popular cloud SERP rank trackers gather their data? Do they use a proxy to do a google search each and every time it updates the rank? Or do they use some other method I am unaware of. If they search on google.com.au using an overseas IP, are these still tallied as local searches? I run a few niche offline businesses. Market research, and proper keyword research is vital to targeting my SEO efforts. Some keywords may only have 1 or 2 daily searches, but bring in thousands of dollars of revenue a week. My concern with the cloud rank trackers, is if they are updating every hour, and I am tracking my rank and my competitors rank, and he is doing the same, that is over 100 extra daily searches for the keyword. This has the potential to drastically over-inflate the value of a keyword, and waste a lot of peoples money chasing phantom searches. Is this a valid concern or am I just being mental?
