SEO: Making Your Page Work

So how do you harness this incredible tool to make your own page's ROI higher? By understanding the search engines and how they work, and by taking steps to ensure your page is optimized for best usability by these engines.

First, search engines use text-based algorithms. They send out miniprograms regularly called search engine spiders, robots, or web crawlers that catalog the data contained in web pages – data in the form of text – and use that to determine where to place a page in search engine returns on keywords.

So when your potential customer types in "butterfly handkerchief," the placement and frequency of your keyword phrase "butterfly handkerchief" is one of the main things a search engine pays attention to when deciding where to rank your page. If you are the only "butterfly handkerchief" site that is clearly demonstrating you offer these by placing the keyword phrase in the header, metatags, and text of your page, then you'll get first ranking. If Billy Bob's Hankies does a better job of this, he will get top ranking, bumping you down.

But that's not all the search engines look for.

SEs will also see the relevancy when the keyword is repeated. Simply stuffing the keywords in the text won't help your site and it may instead be penalized for keyword stuffing.
