Search engine optimization has become a very large field for many different consultants all over the internet.
1. Think Small
The smaller your Web pages are, the faster they load. A single page should be less than 15K (unless absolutely necessary) and the entire page including graphics should be less than 50K (unless absolutely necessary). Remember, not everyone is on a high-speed Internet connection; there are still people without a 56K modem.
Use hyphens ( – ) and not underscores ( _ ) to separate words in directory and file names. Most search engines parse a hyphen like a reader would parse a space. Using underscores makes what_would_you_do look like whatwouldyoudo to most search engines. You should definitely separate words in your URLs.
3. Navigation on Every Page
You should place consistent navigation on every page of your Web site. Your navigation should link to the major sections of your Web site. It would also make sense for every page on your Web site to link back to the home page.
The title of the page should be used in the TITLE tag and at the top of every page. The title should be keyword rich (containing a max of 7 to 10 words) and descriptive.
5. Description META Tag
Some people say META tags are dead but some search engines will actually use them underneath a pages title on search engine result pages (SERPs). Use no more than 150 characters including spaces and punctuation. Your description should be a keyword rich, complete sentence.
