Link farms

[mini_0]

Link exchange is another area that needs to be carefully assessed before any placement. It has been a trend for most Webmasters to set up a link page just to exchange links. This is certainly not recommended especially when the page becomes a Link Farm when it contains too many outgoing links.
Not all link exchanges are bad, links that lead to relevant and quality content is excellent both in attracting traffic and gaining page importance. For example, a link labeled as 'Webmasters Guidelines' is totally relevant when it appears in a website review post.

A websites’ popularity is judged by the number of inbound (incoming) links from other sites, as earlier it was considered that more the links a site had, the more popular it was.

So, to garner more inbound links, sites joined linking programs whose method was ”we give you ‘number’ of inbound links if you can provide us ‘number’ of outbound links”. This is a link farm which is “linking of multiple sites whether relevant or not” and uninteresting sites had higher ranking than better ones.

For example: A school website having links from educational sites (tuitions, courses etc.) is acceptable, but if have links from unrelated sites (political etc.), becomes a “Link farm”, which is spamming and unacceptable.
