LINK SPAM

Link spamming is having links purely to boost the websites page ranking. This is because of the search engines link based ranking algorithms such as Google’s PageRank algorithm which gives a higher ranking to a website with more other highly ranked websites linking to it.

Link spamming includes:

• Link farms

Involves creating tightly-knit communities of pages referencing each other, also known humorously as mutual admiration societies

• Hidden links

Putting links where visitors will not see them in order to increase link popularity. Highlighted link text can help rank a webpage higher for matching that phrase.

• Sybil attack

A spammer may create multiple web sites at different domain names that all link to each other, such as fake blogs known as spam blogs.

• Spam blogs

Also known as splogs, a spam blog, is complete fake blog created exclusively with the intent of spamming. They are similar in nature to link farms.

• Page hijacking

This is achieved by creating a rogue copy of a popular website which shows contents similar to the original to a web crawler, but redirects web surfers to unrelated or malicious websites.

• Buying expired domains

Some link spammers monitor DNS records for domains that will expire soon, then buy them when they expire and replace the pages with links to their pages.
