Page Layout
Arrange the keyword layout of each page efficiently so that they will be spidered better by the major search engines. Search engine reads HTML source codes from left to right and from top to bottom. Put important phrases or search engine optimized paragraphs before images and other multimedia effects.

Cascading Style Sheets
Search engine spiders cannot read CSS style commands. Because cascading style sheets can be long (more than 50 lines), don’t include them within the actual web pages. A separate CSS file should be kept and invoked within web page source codes.

JavaScript and Unspiderable Code
JavaScript on your web pages is not a best friend of the search engines. Search engine spiders don’t recognize JavaScript and making it worse, they may get hung up on it if there are a lot. If you really need to use it, put the JavaScript code into a separate JS file and call it within the head tags.

Font Sizes
The major search engines regard font size as an important element to analyze content. Phrases are considered to have more relevancy to the whole content if they are put between h1 tags. Put the title or key phrases on the top of the pages using h1 through h3 tags. Also don’t use a font size smaller than size 2 unless it’s for copyright.

If you haven’t started to design your site yet been thinking about using frames (also known as framesets), don’t. Frame sets make it hard for search engine spiders to index you and to find sub-pages.

Eventually, web sites began to give more focus to attracting visitors and getting these visitors to take action. With a lack of detailed tracking, these marketing efforts were difficult to measure and adjust. The booming market in search advertising helped fuel the creation of modern analytics software which gave web sites the ability to segment their audience and truly evaluate their marketing campaigns. This not only gave advertisers a level of tracking unavailable in any other form of advertising, it also furthered the science of creating web sites by giving designers a better understanding of how to build sites for maximum effectiveness.
