How To Guide: Prevent Google Proxy Hacking |
|||||
One day your traffic comes to a grinding halt. What happened? Check the index. Google may have found all your reciprocal links from i-hump-sheep.info and white-castle-coupons.biz. But it's also possible that you have been "proxy hacked." That's the term being tossed around by a few people who have been mum on it for awhile — Alan Perkins, Danny Sullivan, Bill Atchison, Brad Fallon, and a few other people that are actually exploiting this hole right now (and whom we don't know). And it's likely the reason Google (http://googlewebmastercentral.blogspot.com/2006/09/how-to-verify-googlebot.html So what's going on? Dan Thies has a summary up about it, and he'll probably do a much better job explaining it since he's not a programmer at heart like me. I'll end up speaking in pseudocode … so read Dan's summary over here. Here's a tidbit that explains a lot of it away: With the introduction of "Big Daddy," Google crawls from many different data centers; they also changed the algorithm substantially at the same time. According to Dan "It appears that the changes include moving some of the duplicate content detection down to the crawlers. [This is problematic. In short:] 1. The original page exists in at least some of the data centers. Oops!How To Fight Back — Code implementationsWell that's where I come in. I have 2 implementations in beta (read: they work according to my tests, but I'm going to be testing more) that address the problem based on the methods the search engines cite. Then, essentially, we're using a benign form of cloaking (yes, cloaking!) to make it more difficult for bad bots, proxies, etc. to exploit us. The code is located hereI'll expand the explanation in that documentation to make it easier to comprehend/install. But if you know PHP, dive right in. The code and concepts were primarily based off on the book I coauthored, "Search Engine Optimization with PHP." It is my sentiment that most SEOs have to be aware of technology more so than they think — hence the book authored by me and co-author Cristian Darie. This is just one example.

Its a very interesting article. When you think of the whole proxy thing, it kind of makes sense that it could cause content to be duplicated. Google really needs to get this sorted out ASAP. Lets hope that bringing this proxy problem out in the open doesn't cause too much damage. Anyway, great site ! Your book is currently in the mail heading my way !
I dont understand this really does someonebody could explain me plz i am not a english speaker thats why
Very interesting article. I'm going to have to do some more research into this. Google says there's no duplicate content penalty, but they also say landing in the supplementals isn't a bad thing. I would hate for that to happen purely because two bots crawl the same page and naturally see the same thing…!
Hi Jamie, Dan Thies pointed me in your direction as I have several website that all run on a Windows server and primarily use HTM, with some pages being asp. However one of my websites is built in ASP entirely. Dan mentions in his blog that you may have been working on a fix for those of us dirty enough to use ASP and windows servers. I just wanted to see if this was still the case and if you have any updates on this yet. Thanks for your efforts so far. As someone who isn't all that savvy in web development and manages to just get by, this is a real help. Kirk

I'm with Kirk,
I wrote a small article and some scripts that might come in handy when fighting this including a small explanation. Dedicated to the PHP coders!
