Keyword Prominence
Search Engine Optimisation
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. 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%.
