This is just an iteration/continuation of my research here. I was reading earlier today about a software on the forum that uses proxies to send fake traffic. First of all, most headless browsers are 100% EASILY DETECTABLE. I've programmed enough with headless Selenium browsers in the second half of 2014 and couldn't find a way that actually generated SERP movements through proxies. Getting fake traffic and navigating wasn't hard but it never proved anything positive. My fellow engineers, read more here for example: http://engineering.shapesecurity.com/2015/01/detecting-phantomjs-based-visitors.html Secondly, this all depends on the proxies you have. If you're some proxy server genius, you may know exactly what you're doing. I'm not an expert with this, I've only sat in on about a dozen lectures on the OSI model and that's about my extent of knowledge in networking. I ripped this reference sheet from another forum, to play a bit of catchup on the basics of proxies: Transparent Proxy Server: Advantage: very high speed Disadvantage: low privacy Particular purpose: bypass firewall restrictions, fake website hit counter, download files from filehosts (rapidshare, megaupload and others) Anonymous Proxy Server: Advantage: average speed, average privacy Possible disadvantage: proxy usage fact is presented General purpose: most suitable for 99% of tasks Elite Proxy Server: Advantage: high privacy, proxy usage fact is hidden Disadvantage: low speed Particular purpose: just very few cases when the fact of proxy usage should be hidden So lets just assume, you are full anonymous. Now, are you using private proxies, as in, are you just using a class of IPs, say 18.104.22.168 to 22.214.171.124? I'm pretty sure Google knows enough to spot an abnormal amount of traffic from a specific ISP. So now it comes down to public proxies as your only hope. How did you find these proxies? There's a 99% chance that they're indexed in Google, and Google already knows they are proxies. So now Google knows that this 75% increase in traffic is entirely from proxies. Do you really think you'll ever see a SERP movements?
