Keyword distribution histogram displays the distribution of a keyword on a page. The histogram from the left to the right displays columns, signifying the number of times the keyword is used from the beginning of the page to the end. The higher the column - the more keywords are used in the current section of the page.
For example, let's analyze Microsoft's start page by the word "Microsoft".
We know that at the moment, when this snapshot was taken, the word "Microsoft" was used 77 times on the page. Among them:
- 3 times in the <HEAD> of the page:
- 1 time in the page <TITLE>
- 2 times in the <META DES> tag
- 74 times in the body of the page, among them:
- 1 time in the tag <H4>
- 5 times in the link text
- 64 times in the HREF parameter of the <A> tag
- 1 time in the <TITLE> parameter of the <A> tag
- 1 time in the SRC parameter of the <IMG> tag
As we can see the beginning of the page contains the keyword three times: 1 time in <TITLE> + 2 times in <META DESCRIPTION> tag. In the keyword distribution histogram these words are rendered by the first small column and the second bigger column. After that goes a big menu, where the word "Misrosoft" occurs 30 times in the link URLs, one time in the LINK text and one time in the visible text. These words are rendered by the third tall column - this is the most dense part of the page in terms of keywords.
Closer to the end of the page there are no occurrences of the keyword - if you open the page source you will see the JavaScript code there.
