Patience is a virtue
Remember that you are competing with hundreds of millions of other websites on the search engines, and patience will prevail! Remember that when you over-submit, you run the risk of being banned from search engines.
Website Content should be your #1 priority!
It is important to have a lot of text describing what you do. Use your keywords in the content, but don't repeat them over and over. Many search engines rate sites based on 'keyword density'. This is usually a formula that looks at META Keywords, words in your TITLE, words in paragraph text, words in links to other pages, and even words in the 'ALT' text on your images. They will even look at different forms of your keywords. For example, if an important keyword for you is 'FISH', the word 'FISHING' in the body of your document will raise the confidence in the word 'FISH' on some engines.
Links to Other Pages
Make your links meaningful. Make sure they relate to what you do (and keywords that are important to you). You can't have too many links on your pages.
Links from other websites
Some search engines place a very heavy rating of importance on how many other sites in their index have links to your website.
Don't use frames
Most search engine simply cannot index a frames page.
Don't try to fool the engines
Search engines catch on and write routines that penalize sites that use this practice. Examples of this include, but are not limited to: repeating keywords over and over; using invisible text (white text on white background); using very small text to jam the keywords in a small area;.
Keep the most important content near the top of your pages.
Some engines will place a higher rating of importance based on where they find the text in your page. Closer to the top is usually better.
Don't stuff the top of your pages with data the engines can't read.
HTML formatting, images, scripts, etc. toward the top of your page can result in lower ratings.
Don't go Image Crazy
We have all seen pages that are almost all images. Usually they are the most beautiful sites. However, the search engines don't have eyes. All they see is 'yourimage.jpg', and 'yourimage.jpg' doesn't go far in terms of content and relevancy.
Look at the competition
Consider everything you have read so far and have a look at the people that have the top 20 positions with the keywords that are important to you. Look at what they are doing and what they are not doing.
