I used to work for one.  I now generally spend about 90% of my day generating SEO traffic through various tactics, so in retrospect, I wish I did some of the following.  In reality, I tried, but got shot down by folks who wanted to see ROI a day later.

1.  Create a blog and put it on your domain.  Heck, build five.  Its easy, and you don’t even need to touch your hosting account if you don’t want to.  Services like blogger let you point it at your primary domain, meaning visitors and Google crawlers see it as yourblog.yoursite.com  .

What’s the benefit?  Content, links, networking, access to new directories - did I mention links?  Its a lot easier to submit a blog to a directory than it is to submit a business site.

2.  Build 5 Blogspot blogs.  Why not?  They take about 5 minutes to set up and it takes a bout 30 seconds to post something.  Note:  you don’t have to post stuff that actually makes sense.  Just put some words on there, and create a few deep links to your product pages.

3.  Write an article for Hubpages

4.  Write an article for Squidoo

5.  Write an article for EzineArticles

6.  Do a Google search for blog directories in your subject matter.  Chances are, you’ll find at least five that are free.

7.  Create a swicki, and put it on one of your subdomains.  Again, more content.

8.  Build a resource site or information center using Wordpress software, and host it on a new domain.  Tailor this resource site to target specific long-tail strings of words that will convert.   Then direct this traffic to relevant product pages.
