Search engine optimization (SEO) is a set of methodologies aimed at improving the visibility of a website in search engine listings. The term also refers to an industry of consultants that carry out optimization projects on behalf of client sites.
To obtain maximum search engine visibility, it is essential to understand how the target audience is searching for actual information on a web site. When the target audience uses a search engine to find products and services, they type a set of words or phrases into the search box. This set of words is commonly called targeted keywords or phrases.
For the target audience to find a site on the search engines, the page must contain keyword phrases that match the phrases the target audience is typing into search queries.
When a search engine spider analyzes a web page, it determines keyword relevancy based on an algorithm, which is a formula that calculates how web pages are ranked. The most important text for a search engine is the most important text for the target audience - the text your target audience is going to read when they arrive at your web site.
