Welcome to WebmasterWorld Guest from 184.108.40.206
Many unethical webmasters and site owners are already creating thousands of TEMPLATED (ready to go) SKYSCRAPER sites fed by affiliate companies immense databases. These companies that have your website info within their databases feed your page snippets, without your permission, to vast numbers of the skyscraper sites. A carefully adjusted variant php based redirection script that causes a 302 redirect to your site, and included in the script an affiliate click checker, goes to work. What is very sneaky is the randomly generated meta refresh page that can only be detected via the use of a good header interrogation tool.
Googlebot and MSMBOT follow these php scripts to either an internal sub-domain containing the 302 redirect or serverside and “BANG” down goes your site if it has a pagerank below the offending site. Your index page is crippled because googlebot and msnbot now consider your home page at best a supplemental page of the offending site. The offending sites URL that contains your URL is indexed as belonging to the offending site. The offending site knows that google does not reveal all links pointing to your site, takes a couple of months to update, and thus an INURL:YOURSITE.COM will not be of much help to trace for a long time. Note that these scripts apply your URL mostly stripped or without the WWW. Making detection harder. This also causes googlebot to generate another URL listing for your site that can be seen as duplicate content. A 301 redirect resolves at least the short URL problem so aleviating google from deciding which of the two URL's of your site to index higher, more often the higher linked pagerank.
Your only hope is that your pagerank is higher than the offending site. This alone is no guarantee because the offending site would have targeted many higher pagerank sites within its system on the off chance that it strips at least one of the targets. This is further applied by hundreds of other hidden 301 permanent redirects to pagerank 7 or above sites, again in the hope of stripping a high pagerank site. This would then empower their scripts to highjack more efficiently. Sadly supposedly ethical big name affiliates are involved in this scam, they know it is going on and google adwords is probably the main target of revenue. Though I am sure only google do not approve of their adsense program to be used in such manner.
Many such offending sites have no e-mail contact and hidden WHOIS and no telephone number. Even if you were to contact them, you will find in most cases that the owner or webmaster cannot remove your links at their site because the feeds are by affiliate databases.
There is no point in contacting GOOGLE or MSN because this problem has been around for at least 9 months, only now it is escalating at an alarming rate. All pagerank sites of 5 or below are susceptible, if your site is 3 or 4 then be very alarmed. A skyscraper site only need create child page linking to get pagerank 4 or 5 without the need to strip other sites.
Caution, trying to exclude via robots text will not help because these scripts are nearly able to convert daily.
Trying to remove a link through google that looks like
new.searc**verywhere.co.uk/goto.php?path=yoursite.com%2F will result in your entire website being removed from google’s index for an indefinite period time, at least 90 days and you cannot get re-indexed within this timeline.
I am working on an automated 302 REBOUND SCRIPT to trace and counteract an offending site. This script will spider and detect all pages including sub-domains within an offending site and blast all of its pages, including dynamic pages with a 302 or 301 redirect. Hopefully it will detect the feeding database and blast it with as many 302 redirects as it contains URLS. So in essence a programme in perpetual motion creating millions of 302 redirects so long as it stays on. As every page is a unique URL, the script will hopefully continue to create and bombard a site that generates dynamically generated pages that possesses php, asp, cigi redirecting scripts. A SKYSCRAPER site that is fed can have its server totally occupied by a single efficient spider that continually requests pages in split seconds continually throughout the day and week.
If the repeatedly spidered site is depleted of its bandwidth, it may then be possible to remove it via googles URL removal tool. You only need a few seconds of 404 or a 403 regarding the offending site for google’s url console to detect what it needs. Either the site or the damaging link.
I hope I have been informative and to help anybody that has a hijacked site who’s natural revenue has been unfairly treated. Also note that your site may never gain its rank even after the removal of the offending links. Talking to offending site owners often result in their denial that they are causing problems and say that they are only counting outbound clicks. And they seam reluctant to remove your links....Yeah, pull the other one.

I will lay down the blueprint.
Clause will endorse it with a few modifications.
""""BANG"""" WE DO IT.
I can see it now, just like a hail of bullets leaving a trail of speeding neon lights in the night sky. Thousands of them, maybe millions. Depends on how big the target is.
Googlebot has no referrer. Stargeek made a brilliant suggestion that, should googlebot carry a referrer, then it would be easy to block it.
The idea can possibly work, if googlebot is forced to notify all 302 referrers, then we know when the danger is coming from.
Referrer only when the bot is on its way to you via a 302.
Simple and effective.
[quote]A Google representative, speaking unofficially, suggested that only one "concrete" example of a domain being hijacked in this manner had been proven to Google engineers. However, he urged the wider webmaster community to post any examples of "domain jacking" that they find to webmaster [at] google.com, with the keyword "canonicalpage" in the e-mail title, so that Google engineers can properly investigate whether there Google feels there is a real charge to answer.[\quote]
the article also mentions a big name "SEO expert" who agrees that this is an issue, perhaps we could get his approval on a campaign.
I'm not talking about blocking goglebot referrals I'm talking about screening referrals from known problem links and blocking them.
sorry if i was snappy in that post this is causing me headaches (google, not you).
the only way to know where a hit came from is to check the http variable "referrer" normal web browsers "carry referrers" meaning they provide a value that is the last page they were on.
if a normal web browser goes clicks a link from example.com to your site and your site checked the referrer string it would see example.com.
problem with this is that google does not follow links in this way and therefore there is no referrer value to check.
googlebot's traffic from the offending site to your site is the traffic you'd want to block, but it is impossible to tell if google is coming from a redirection or just indexing your site.
I also found googleguys post in another forum that the article refers to.
(i.e. "site A appears to have duplicate pages from, or is doing a 301/302/whatever to site B, and Google is wrongly picking site A as canonical", with actual values for A and B), I'd be happy to hear them. Drop an email to webmaster [at] google.com with the keyword "canonicalpage" (all as one word) and I'll ask someone to collect the feedback and pass it on to an engineer.
anyone who has been hijacked start sending then e-mails of known examples.
all the emails to them in the world won't make it worth it to them to fix it, every time a webmaster looses free traffic google gets an adwords customer.
we have to take it a step further, google won't fix this on thier own.
Big dot com engineer decides to modify htaccess so that non-www redirects to with-www but does not specify 301, default is 302.
Google spiders big dot com twice, once with www and once without so there are 2 copies of every page in googles index.
Googles duplicate content filter bans big dot com.
Big dot com freaks, fires engineer and freaks on google.
Google does rollback on index to restore big dot coms SERP's immediately.
