Thank you very much.

So if i have 2 domains & 100 keywords for each, and targeting 35 Goolge search engines. The total number of searches will be 7000, and i will be checking the rankings only once a month. How much it will cost me? Regards.

Thanks. I have one more question, i do not understand this payment system of yours. I want to buy 500 search queries, but i am confused with the interval part because the price difference is very high between all the intervals. Can you please gimme a little explanation on this? Thanks
