The point on this is that the math's are different so you will never get your website in the first 10th all over the web and that will give some balance to promote others, I built a 100% seo website and also W3C compliant and after four months from birth hit the 4th page competing with a more than a million other sites having the same tag string or keyword string and 1st on unique keywords both on google and Yahoo! (different keywords) and all this without exchanging links or affiliate or whatever kind of recip. links you can come out off, let say it outloud... I  vote against any kind of link usage for promotion unless you want to add someone else on your site, as I did,  in good will.      

My formula :

1) Build a website for costumers not for search engines.

2) Try to give some addon for the visitor like articles with non-tech words.

3) Check for validation of your pages (individually) and the CSS at www.W3C.org and add the validity icon to your site.

4) Check for Meta Tag and such till you get 100% (green) at www.seocentro.com.

5) Check 100% at www.whois.sc + their SEO checker.

6) Use free "addurl" websites.

7) Write good articles and find a top PR articles website to publish your work.

8) Participate in forums and blogs and share your knowledge on your field.

9) Make (as I did) a funny video and a serious one about your business and publish it to the web.

HOPE I HELPED, (this is another way to promote your site... by helping others with reliable or valuable info)
