Content
Your content must be original, relevant, and useful. Well written and unique content is mandatory

Titles and Meta Tags
Meta-tags were the primary way to attract search engine traffic in the past. Meta-tags help describe the content of your website. Today’s search engines not only look at meta-tags, but also validate your site content and link popularity. Relevant meta-tags can be a tie-breaker in your site’s rankings today.

Keyword Market Analysis
Keyword Market is the total number of unique searches relevant to your website. A Keyword Market is the top-level keyword that is most relevant to your site. Many vertical keywords may be contained in a Keyword Market.  In order to drive traffic to your website, you must select and build your website to target specific Keyword Markets.

Link Popularity
This is the number of websites that contain links to your website.  These links determine the relevancy of your site for a search term. Links from popular sites with high PageRank have more weight in the search engines.

Link Quality
Link Quality is determined by the popularity of websites containing your links and the relevancy of sites linking to your site.

Relevancy
Relevancy is also determined by the actual text that other sites use when linking to you. The search engines determine the relevancy of a specific term, if this term is used to link to your site, rather than simply linking by your website’s URL.

Link Architecture
Search engines use the links within your website to crawl and index your website. Flash entry pages may prevent “finding” your content.  Also, a good practice is to link the pages on your site to your index page using your target keyword, e.g., instead of ‘home’, use ‘Internet Marketing’

Updates
Google checks the update frequency and the size of each update to your site. Updating your blog weekly is critical to building your PageRank.

Dynamic Sites and URLs
Dynamic sites are a powerful way to have frequently changing content.  Using database technology, a web page isn’t built until it is requested from a user, guaranteeing that the content is up to date.

Search Engine Submission Links: Free Submissions
Once you’ve changed your content, you can use the free submission features of the Search Engines to “list” your site.  You must be careful, however not to submit your website unnecessarily or excessively.
