So what is the real story here.
Do these sites particpate in link exchanges or not?
Or are we to believe that it all comes naturally?
The number 3 site listed is also a PR0?
But they always seem to come up a lot on search results.
If blog comments, forum sigs, articles and link directories are dead practises then whats left. The only seeming consensus is ‘good content’. Only one suggestion that comes off the top of my head is guest blogging.
