Keyword prominence is how close to the start of the area that the keyword appears. In general, a keyword that appears closer to the top of the page or area will be more relevant. However, sometimes it helps to have a keyword in the middle of an area, or even toward the end of the area.

For example, an Infoseek search for keyword “Pre-Owned Electronics” returned the following match:

Pre-Owned Electronics, Inc - Refurbished and Used Apple Macintosh Systems, The independent source for new, remanufactured and used Apple Macintosh computer systems, parts, peripherals and accessories. We offer a full line of refurbished as well as used… 98% http://www.preowned.com/ (Size 3.1K)

Note that the queried keyword, “Pre-Owned Electronics,” is the first word of the site title and InfoSeek returned this site as the first match. Documents that are exactly the same, but with keywords as the second or third word in the Title will often score lower. Prominence also applies to the words within the body of the document, the headings, and other tags.

Prominence plays a critical role particularly in directory based engines such as Yahoo. Often having the keyword slightly more towards the beginning of the site description or site title will make a large difference in your ranking.

Examples of prominence:

If a keyword appears at the beginning of an area, its prominence will be 100%.

If a keyword appears in the middle of an area, its prominence will be 50%.

If the keyword appears at the beginning of the area, then another repetition appears at the end of the area, the prominence would be 50%.

If the keyword appears at the end of the area, prominence would be 0%.More>

Keyword prominence
the location (i.e. placement) of a given keyword in the HTML source code of a web page. The higher up in the page a particular word is, the more prominent it is and thus the more weight that word is assigned by the search engine when that word matches a keyword search done by a search engine user. Consequently, it’s best to have your first paragraph be chock full of important keywords rather than superfluous marketingspeak. This concept also applies to the location of important keywords within individual HTML tags, such as heading tags, title tags, or hyperlink text. So get in the habit of starting off your title tags with a good keyword rather than “Welcome to.” More>
