6. Write an accessible site (HIGH PRIORITY) Accessible HTML is accessible to both search engine spiders and screen readers. The more accessible you make your pages, the easier it will be for search engines to read and rank your pages. 7. Use the keyword phrase in your title tag (HIGH PRIORITY) The title tag is one of the most important tags on your Web page. And placing your keyword phrase in the title tag, preferably at the beginning, is very important to get that phrase into the search engines. Plus, that puts your keyword phrase as the link in the search engine index. 8. Get a domain with your keyword phrase (HIGH PRIORITY) Putting your keyword phrase in your domain name is a great way to optimize for that phrase. 9. Use the keyword phrase in your URL (HIGH PRIORITY) Even if you can't get your keywords into your domain name, you can put them into your URLs. Search engines read the URLs and assign value to the text they find there. 10. Use your keyword phrase a lot, but not too much (HIGH PRIORITY) The ratio of your keywords to the rest of the text on your page is called the keyword density. It's important to repeat your keywords in your document, but not too much. Keyword density should be between 3 and 7% for your primary keyword phrase and 1-2% for any secondary keywords or keyword phrases.
