Hi I manage 5 sites. For each one I should tracking the rank for about 50 kw per site. I use RankTracker and would like to know how many proxies should I use. I run reports everyday, so I should track about 250 keyword per day. I have scheduled report on different hours. So for example I run a report at 3:00 (50 kw) another at 6:00(50 kw) and goes on.... Could you give me an opinion?
