Meta-Data Optimization/Titles and Meta Tags
Meta Tags (keywords and description) and Title Tags are pieces of HTML code that helps describe and classify the content on a web page. Having a uniquely optimized title on each page is critical for obtaining the best possible placement within search engine results.
When the titles and meta tags properly support the content on each web page the potential placement of that page increases when being searched for on the internet.

Keyword Market Intelligence
Your keywords are your life. You absolutely need to understand your online keyword market intimately and begin speaking to it. Your keyword market is the natural "search language" your customers are using to try and find you online. It’s the quirky combination of terms that someone comes up with while trying to accurately describe something very specific to them. There are plenty of excellent keyword research tools on the market. Yet there are a few that are considerably better than the others.

Dynamic Sites and URL's
A dynamic web page is a template that displays specific information in response to queries. Most of the page content comes from the database connected to the website. Visitors love them since they get quick access to the information they want. Search engine spiders have a much tougher time with dynamic sites. Some get stuck because they can't supply the information the site needs to generate the page. Other spiders deliberately stay away from dynamic pages to avoid getting trapped in the site.
A dynamic URL is the address of a dynamic web page.
Dynamic URLs often contain the following characters: ?, &, %, +, =, $, cgi-bin, .cgi.
