| When you search for a topic using a search engine, such as Google, you will almost instantly sort through the millions of pages in the engine's database and receive the ones that best match your search topic. The best match for your search will be listed first.
However, search engines do not always get it right. Sometimes pages that don't relate to your search make it through, and sometimes it may take a little work to find what want.
Search engines follow a set of rules to determine which pages best match your search. The main rules are related to the location and frequency of keywords on a specific Web page.
Search engines will also check to see if your search words appear near the top of a Web page, such as the headline or the first few paragraphs of text. The assumption is that any relevant pages will mention those words in the beginning.
How often a keyword or key phrase appears in the Web page is another factor in how search engines determine relevancy. A search engine analyzes how often keywords appear in relation to other words in a Web page. Those pages with a higher frequency of keywords are often considered more relevant.
