Just checking the stats of my site I'm getting a weird link from google to my site this is where someone is linking to my site I have 121 visits from this url rate-limited-proxy-72-14-199-13.google.com/ What is this?
Is it a permanent backlink or just a visitor? If it's the latter might be someone using a proxy server.
If the referrer come from someone under the hood of Google.com, then I would say they might be a human staff hired by Google to checking all websites on daily basis However, I have had found the similar but they are not actually from Google but just a garbage content scraped blog scraped my contents with backlink to my website. Should I say thank you to them? No for me and I do think the kind of backlinks won't do any good to me.
I think you can say thank you to them, at least I do. They come my site, steal my content, in return, give me backlinks (sort rubbish and nofollow) and traffic (junk traffic too). But, that's what suppose to happen on internet, the Google, and the other search engines basically doing the same thing, just they are doing really good.
if it come from google.. whether backlinks or traffic it not bad.. so i think you have to worry about it..
