- Get new domains for new sites
- Participate in link exchanges
- Wordpress is good because it is free
- Post to high Page Rank directories
- Target keywords with low competition
- One way links beat reciprocal ones
- Perform directory submissions manually
- Link to your web site from your articles
- Target two keywords per web page
- Use descriptive anchor text in home page link
I found these tips very interesting. The only one I would hesitate to use would be the link exchange. Recently there has been a lot of talk in the SEO community about Google penalizing sites that sell links. And it might be the case that you would get penalized with link exchanges as well.
My plan is to create some new sites, and see how link exchange participation affects then. This is good practice for any SEO technique. Ideas are great. But testing them out gives you the hard evidence you need to make crucial decisions. Due to the ever changing rules of the search engines, you may need to continually retest your assumptions as well.
