since some members ask about it, the one I use is proxyrack
i don't like mobile IP or VPN
the keyword is rotating. Do you want the IP to be static or not, think hard as the price difference is huuuuuuge. Rotating is usually more expensive.
and whether you want a data centre IP or residential?
now if you use mobile IP google can still track your real IP using triangulation wifi, other mobile device in your home, your ISP connection node, i don't like it. They will not know 100% per se your exact location, but it's close enough. It could or could be not a problem depending on what you are doing, whether it's black hat or white hat, whether you are trying to monetizing the CTR using google adsense with clickthrough or impression (probably the later), and whether you are doing GMB CTR, etc ...
if you use vpn, google will NOT see your "real" IP, but all the traffic will be ALL coming from the EXACT IP of the VPN. If you are doing scraping it's A-okay, if you are doing CTR, I don't know man. Let say you send 300 interactions per hour, all with the same IP, you do the math ....
