Google KNOWS when you are trying to SEO for a certain keyword! you have to be careful how you check your ranks and monitor your site or else google will derank you. So I have been ranking for keywords with a few of my websites all in one niche. And there is one keyword that i have been checking on a daily basis on my computer. So i type the keyword in, see that i'm ranked no.1 or no.2 and then sometimes click on the link. However, i change my IP on a daily basis because I have DSL, but it still keeps the first two blocks in my IP the same every time. for example: 97.171.XX.XXX It seems google has something in it's algo that recognizes when IPs on a network do a google search for a keyword often (in my case on a daily basis at the very least), and when that user click on a particular result (my site). Because my site is no longer ranking on any IPs unless they are one my DSL IPs. i.e.- 97.171.XX.XXX I've gotten many new ones from my dsl and it still ranks but only on those IPS. But when i use a proxy or when i use my neighbors cable internet or my cell phone or hidemyass it is not ranked at all. i've cleared my flash cookies, my cache, temp internet files everything, and it still ranks on my network of DSL ips but nowhere else. I have been tracking my results for days and i've been in the top 3 for weeks now and i've checked from proxies all sorts of IPs and i've always ranked until today and now i only rank when i'm on a certain range of IPs. Has anyone else experienced this? perhaps i'll be checking my ranks in the future with different ips on different networks as often as possible. I'm convinced google is showing me my site ranking only on my network because they know i'm trying to rank for this keyword. NOTE: I HAVE CLEARED MY CACHE, TEMP FILES, NOT BEEN LOGGED INTO GMAIL THE ENTIRE TIME I'VE BEEN TRACKING MY RANKINGS. GOOGLE EFFECTED ANOTHER ONE MY KEYWORDS TOO THAT I'D BE TRACKING A SIMILAR WAY.
