According to the Media Post, July 20th 2007.
1. Don’t reply to the SEO spam you get via e-mail. You don’t need to submit to 1,000 search engines or 500 directories. You can’t buy 2,000 quality links for $50. And no reputable SEO can guarantee a number one ranking on any search engine for keywords that matter. The kind of SEO company you want to hire doesn’t send out spam.
2. Don’t wait too long to implement SEO. Whether you’re launching a new Web site or upgrading your current site, SEO considerations should be part of the discussion from day one.
3. Don’t take your decision to hire an SEO company too lightly. Hiring an SEO company is not like choosing a company to service your copy machine. Online marketing can make or break your company, so choosing a vendor should involve a lot of research and questions with the companies you’re considering.
4. Don’t hire an SEO company and then divorce yourself from the process. It’s your job to know and understand as much as possible about the strategies and tactics your SEO company will be using. If your SEO company uses high-risk tactics and your site gets caught, you’ll be the one paying the price.
5. Don’t spread your content over several domains. There are times when sub-domains or an additional domain might make sense, but those occasions should be dominated by user and content considerations, not an attempt to get multiple domains/sites listed in the SERPs. Know the pros and cons of using sub-domains and additional domains.
6. Don’t waste your time submitting your URL to search engines. The crawler-based search engines will find your site more quickly as soon as you get a link from another web site already being crawled. Search engine submission died a few years ago.
7. Don’t make your web site uncrawlable. This can result from an incorrect robots.txt file, having session IDs or too many variables in your URLs, using a convoluted navigation menu that spiders can’t (or won’t) follow, or developing an all-Flash, all-graphic, or all-AJAX site.
8. Don’t target overly general keywords. A real estate agency in Wichita has no shot at ranking for the phrase “real estate;” a lawyer in Fresno has no shot at ranking for the word “lawyer.” Optimize for relevant, specific keywords that will bring targeted traffic.
9. Don’t stuff keywords in your meta tags, image alt tags, etc. That is so 1996-97. Today, it’s called spam.
10. Don’t stuff keywords in your page footer with lightly-colored or hidden text. That is so 1998-99. Today, it’s also called spam.
