Your meta keyword field should be littered with significant and descriptive words about your business, page or product, preferably words that appear in the text of the site. Separate them with commas and string them together. (ie., web, web tech, web tech blog, web blog,...). Your meta description should be a sentence, (a long sentence), also full of those same keywords but in an easy to read description. This is how you'll be identified by the search engines.

Programs like Dreamweaver make it easy for anyone to build a website, but too often these budget priced websites, though they may look good, have forgotten the basics, making it far more difficult for customers to find you. If it's worth building, it's worth promoting.
