An Intro to SEO - Chapter 6 - Measuring a site's success
There are lies, damned lies and statistics
Its useful to know how your site is progressing and to be able to compare it to other similar sites. There are a few metrics that are often used, they are listed below in order of relevance.
Link Popularity. This is the number of sites linking back to your site. This is good metric, the more the better.
Page hits. Not to be confused with file hits. This is the number of times each page has been requested. It might be tempting to think that more hits = more popular but it could just be users getting lost on your site.
File Hits. This is the number of files that have been requested. This includes all types of files like pages, images and scripts. This is a poor metric and was often used to artificially inflate a sites popularity.
