Keyword Phrase

When you string 2 or more descriptive words (known in SEO as "keywords") together, this is known as a keyword phrase. Computer users on the world wide web surf the Internet using keywords and keyword phrases. Keyword phrases are also critical to the way a search engine works. Keyword phrases make it easy to access information and websites on Internet without consulting some gigantic "Internet URL directory" every time we're looking for a hotel in San Francisco.

We use keywords every time we use a search engine, when we enter in words or phrases into the search box. Online advertising (such as Google AdWords and AdSense) generally revolves around keywords. Internet advertisers are able to display relevant ads to a targeted audience thanks to the concept of keywords and keyword phrases. If an advertiser is selling vintage baby cribs, they won't display ads to everyone on the world wide web; this would be inefficient and costly. Instead, advertisers will pay to have ads displayed to people who are searching for or reading articles about parenting and antique furniture, or related goods and services.

Since the invention of hypertext (which allows you to click on a highlighted, keyword phrase link in the middle of a sentence and be taken to further information about that subject) and the creation of the world wide web (the most popular example of hypertext), keywords and keyword phrases have become so common that they're often taken for granted. Being able to pinpoint succinct keyword phrases is now a common part of our culture and psyche.

Advertisers agree to pay a certain amount to websites if their ads are displayed on websites containing certain keywords or keyword phrases that are related to their ad or product (this is know as pay per impression). Other advertisers pay the website only for the ad impressions that are clicked (this is known as pay per click). Either way, there is generally much more competition for popular keyword phrases, so the advertiser agrees to pay more to the website displaying their ad.  Some top paying keyword phrases may earn websites as much as $50 per click.
