Is there any way to discover which of our keywords rank, say, within the top 50 in Google SERPs. Right now, we're using Rank Checker with a save keyword list of about 80 keywords which I manually entered. We need this to prepare a Ranking Report, so we would like to know all the keywords we rank for and their appropriate position. Is there any tool out there, free or paid, that can offer this comprehensive analysis?? We've used SEODigger.com, but our site is not listed yet.
Yes there is, but you need a Google soap API if you want to research more than 125 search terms. If you have a soap API go to cleverstat.com and download "Free Monitor for Google" A paid version researches all major SE. The results are not 100% correct but very close to (as with any other tool) If you don't have an API we can talk about a research, I could do for you.
IBP is what you are looking for. It provides accurate results of keywords that are ranking in different search engines. But IBP is not free! You have to pay for their software and services.
