# keyword weight

Document Sample

```					Keyword weight is the percentage or concentration of keywords on your
page in relation to all other words on the page. A "keyword" can be
either a single word, or a short phrase.

Keyword weight refers to the number of keywords appearing in the page
area divided by the total number of words appearing in that area. Weight
also depends on whether the keyword is a single word or a multi-word
phrase.

Weight formula:

(number of words in the keyword phrase * frequency) / total words in area

Therefore, you're weight will logically increase when the number of
keywords on the page increases or the number of words on the page
decreases.

Some search engines consider keyword weight when determining the rank of
your page for a particular keyword search. In general, the higher the
weight the better, but only to a point. If your weight becomes too high,
you may be penalized.

WARNING: Simply dividing the frequency by the total words on the Page
Analysis table will not yield the correct weight when the keyword is a
multi-word phrase.

For example, if the area had only three words in it:

My Blue Widgets

And the keyword phrase was "Blue Widgets," then the following statistics
would be displayed:

Frequency: 1

Total Words: 3

Weight: 66%

The reason weight is not 1 divided by 3 in this case, or 33.3%, is that
the keyword occupies two of the three "word slots" in the title,
commanding a 66% weight. If we didn't compute it this way when doing an
exact search, then a title of:

Blue Widgets

would yield a frequency of one, and a word count of two. However, it's
obvious in this example that simply dividing 1 frequency by 2 words is
not correct since it would yield a 50% weight rather than a 100%. The
weight must logically be 100% because there's no way a title called Blue
Widgets with a keyword phrase of Blue Widgets could have a higher weight.
100% of the words in the area are already keywords, thus yielding a 100%
weight.
Ultimately, it doesn't matter much how weight is calculated exactly so
long as it is consistently applied for each page analyzed. If top ranking
pages tend to have a 3% weight as computed by the Page Critic, then 3% is
what you want to shoot for regardless of how the 3% if computed. The goal
is to emulate the statistics of top ranking pages. If you focus on
emulating the frequency and word count of top ranking pages, your weight
will generally fall in line.

The starting point column in the Page Critic tells you how far down the
page a particular area begins. The Starting Point column is displayed
only when you turn the detail lines on by de-checking the "Summarize"
checkbox on the Page Critic screen. This number is in terms of the number
of words down the page it starts at.

This statistic is useful in determining how prominent a heading tag,
hyper link, or other area appears in relation to the top of the page. In
general, the closer to the top of the page a keyword/area appears, the
higher it will be scored.
