Keyword prominence - measures how close the keyword appears of the beginning of the sentence. The closer to the beginning your targeted keyword appears, the higher the prominence will be, with a higher keyword prominence being favorable. Prominence applies to word in the title, web page body, META tags, Heading tags, and the alt-tags.
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.
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%.
Keyword proximity measures the closeness between two keywords.

Detta är ju inte raketforskning direkt, utan endast rent sunt förnuft.
Tänk på det så här.
Du skriver en artikel om VOLVO och första ggn. man hittar ordet VOLVO i din 500-ords artikel är i näst sista meningen av artikeln.
Det kan ju aldrig va bra om man ska övertyga läsaren (eller sökmoterers robotar) om att artikeln handlar om just VOLVO.
