Be wary of link exchanges, only swap links with relevant businesses
This morning I participated in a forum discussion on a recurring subject: Should you exchange links with other businesses?
It’s a well known fact that a large number of inbound links to your site can improve your search engine ranking. Google views a high number of links as a "vote of confidence" in your site. What is less well known is that Google also looks at the relevance of the links to your site. e.g. If you are a construction company, it may be helpful for you to have inbound links from an architect and surveyor. But it won’t make much difference if the link is from an online jeweller.
