Analyze Keywords for Search Engine Optimization

Keyword Density Analysis Example

Here is an example that explains normal keyword analysis versus weighted keyword analysis:

<html>
<head>
<title>ExampleWord1</title>
</head>
<body>
ExampleWord1 ExampleWord2
</body>
</html>

As we have set <title></title> to weigh 7 and normal body text to 1 we get result:

Understand the calculations and how:

Count of words is summed:
ExampleWord1 = 1 (title text) + 1 (normal text) = 2 in count.
ExampleWord2 = 1 (normal text) in count.
Weight of words is summed:
ExampleWord1 = 7.00 (title text) + 1.00 (normal text) = 8.00 in weight.
ExampleWord2 = 1.00 (normal text) in weight.

Percentage calculations are just using standard math converting those values into percentages.

Understanding "Merged" Score Stats

Calculating the true importance of a multiple word phrase has an additonal layer of possible calculations.

It is always relevant to calculate and check the:

Count of the phrase and Counted percentage
Weight of the phrase and Weighted percentage

However, above may not be enough to truly show the density and importance of a phrase. The reason for this is that a search engine will also take into account how often the individual words in a searched phrase occurs.

This is where the Merged scores come into play. It merges the results of all the possible individual and combined scores. (With the percentage being calculated against the total possible.)
