Approx. 10-15 should just be fine. One best way to understand whats best, is search websites with high PR and check their the number of Meta tags in the page source.

Along with using "link:yourdomain.com " in google and yahoo, you can also check Yahoo site explorer. It will diplay the backlinks to your website.

Thanks a lot for that. I was searching for this.
