What is WebSpam actually? according to techweb, WebSpam is “Web pages comprised of advertisements and links to other Web sites that contain mostly ads. The pages may pretend to provide assistance or facts about a particular subject, but the help is often meaningless and the information shallow …”
Now, we know WebSpam could be annoying and even sometimes endanger your PC (maybe it’ll force you to download malicious softwares or any others). There are many ways for webmasters (in this case, we call them as spammers) to trick search engine robot to get traffics for their site. Such as:
- Keyword stuffing + Hidden Text or Hidden Links
Keyword stuffing is the excessive use of keywords on a page. It can be done by spammers by hiding out some text, using javascript to hide it, or maybe by putting it into area that visitor doesn’t realize (For example, in the corner of the page, or using very tiny text that is difficult to see, etc). - Use of 100% frame pages
See the URL of the frame, is it the correct site? If it isn’t, it could be considered as a spam page. - Sneaky redirects
Spammers sometimes redirect users to a different domain. You will notice that the URL you click, is different from URL you want to open. Watch the address bar carefully. Try to disable and enable JavaScript on your browser, and see the differences. - Pages with PPC (Pay-per-click) Ads only
