There are two parts to SEO. Content and Links. The more content the better. You need to keep adding content as it does two things for you. It grows your site and keeps it fresh. The major search engines look at both of these when determining importance of your site. It's also important to structure your content correctly. You want a pyramid structure. One of our sites is GamblingMethods.com. You can go look at the view source and get an idea of how this is structured. The menu system allows the google bot to go through it fast and easy so all of the pages are indexed. Some of the pages link to other pages within the site. This further allows google to find all the pages with ease.
The next part is linking. That's what we are here for. Although the major search engines place importance on relevant links it does not discount non-relevant links. That means that links to your site will help you. Also one way links will help you more than reciprocal links. It is not known how much one way links help more than the other. All we know is that it does help enough for people to want to pay to get them. Another important fact about links is that they come from multiple sites..i.e. not links farms. Links farms are sites that are electronically generated for the sole purpose of generating links. We do not do that here. All of our links come from people that want the free subscription and therefore choose to reciprocate.
