I wonder, what the different beetwen link popularity and backlink. . . maybe anyone can answer it for help me. . .
Everything is not so complex. Let's understand the difference between these two definitions. Backlinks are just incoming links to a website, and link popularity is "a measure of the quantity and quality of other web sites that link to a specific site on the World Wide Web", according to wikipedia. So, as you can see, backlinks are just incoming links, and link popularity can be a charateristic of various links, including backlinks.
I'm still not understand. . . when I check my link on backlinkwatch.com, their tell me the same link with link popularity, "my link popularity is 4000++", and "link to your website is 4000++". . . what mean it??
