Links from other sites
If you have access to your web server logs the referrer information can be extremely useful in determining what sites link to yours. Many of the referrers will be search engines which we’ll discuss next time, but there will also be links from other sites.
For this part of our discussion, we’re going to look at 4 different types of links; directories, paid links, reciprocal links, and natural links; plus a few miscellaneous types at the end.
