What are links?  What are the best links to have to my website?

There are two types of links or linking: one-way linking and reciprocal linking. The best links you can have are relevant, one-way links to your website. While the value is not as significant, there is still value to trade links with other websites - called reciprocal linking.  Your goal in finding links, one-way or reciprocal, should be always be relevancy.
