Web Design Tips for Search Engine Optimization [con't]
A very important step after you finish coding your website is to run a test to check whether your code has been written according to the W3C norms. Several search engines are quite finicky about code that doesn't adhere to W3C standards. Submit your website to validator.w3.org and see what it says. I recommend fixing any errors it throws and repeating the test until your website is fully compatible with W3C standards.
Broken code can hamper a search engine's ability to crawl your site. For example, check to make sure that you have closed all tags and basic things like that. Small mistakes like unclosed tags can confuse spiders and result in your pages not being indexed correctly.
Content Is King
Whatever you do to optimize the code and design, at the end of it all it's the content in your website that will have the biggest impact on its ability to be search engine friendly. I've read in several places that it is a good idea to have about four to five paragraphs of content on each page of your website but not to exceed 2500 words. In my experience, having 1000 to 1500 words per page split into about five paragraphs is optimal. However, there is no hard and fast rule here. Just make sure you concentrate on getting good, original content on your pages.
