Study exposes search spam

Everybody knows that during searching for "phentermine" you surely will find a great variety of one-page Web sites that will send you to other Web site instead of required. Thanks to that, will be generated click-through advertising revenue. It is very irritating and is not good for your profit.
Microsoft Corp. and University of California developed the way how to stop the practice of so- called "search spammers".
Prof. Baranovski’s ( project is supposed to support advertisers in order to examine those who have the profit from the spam traffic; moreover this project will give the long and health life to the Web.
This project is going to have review at the 16th International World Wide Web Conference in Banff, Alberta this May.
The main topic is so-called redirection spam; actually the problem is that when user clicks on uniform resource locator (URL) he gets automatic redirect to different URL and receives advertising from there.
Let’s look at one example: you go to, a popular travel services site, and there you find 5 layers which are located between lawful advertisers; it appears that advertising goes from a syndycator that have purchased space on aggregator’s high-traffic Web pages.
As a matter of fact, Web spammers sell traffic to aggregator and give them opportunity to go to the millions pages in order such products as ringtones or prescription drugs find costumers. There is also another mechanism that also distributes URLs – inserting on blog of a user as comment.
When some link is clicked you get redirection to other page, brining benefit back to its controller through pay-per-click advertising. Such company as Google Inc. offers that thanks to AdSense program.
But after appearing Web page analysis and new spam detection it is possible to reduce redirection chains.
Among four unique URLs that were found in the top 50 were spams. "Splog" – is the blog that made for marketing purposes.
According to other study, it was found out that domain is responsible for 22-25% of all the spam that were detected during the research.
The two blocks of Internet protocol (IP) addresses were narrowed down in order advertisements go to the pages of spamers. It is alike the bottleneck, the most convenient point where layer can attack searched spam.
It is obvious that advertisers should be more attentive to the places where their ads are.
It is also clear that advertisers' money play the main role in developing spam industry that in turn lower the quality of content and productivity of Web.
