Keywords also dominate our search intent and interaction with the
engines
For example, a common search query pattern might go
something like this

When a search is performed, the engine knows which pages to
retrieve based on the words entered into the search box
Other data,
spelling, punctuation, and capitalization of those terms provide
additional information that the engines can use to help retrieve the
right pages and rank them

For obvious reasons, search engines measure the ways keywords are
rankings is, therefore, to ensure that keywords are prominently used
in titles, text, and meta data

The map graphic to the left shows the relevance of the broad term
books to the specific title, Tale of Two Cities
Notice that while there
are a lot of results (size of country) for the broad term, there is a lot
less results and thus competition for the specific result


Whenever the topic of keyword usage and search engines come
This is tragic
Keyword density is, without question, NOT a part of
modern web search engine ranking algorithms for the simple reason
that it provides far worse results than many other, more advanced
methods of keyword analysis
Rather than cover this logical fallacy in
The Keyword Density of Non-Sense

The notion of keyword density value predates all commercial search
engines and the Internet and can hardly be considered an
information retrieval concept
What is worse, keyword density plays
no role on how commercial search engines process text, index
documents, or assign weights to terms
Why then do many
optimizers still believe in keyword density values? The answer is
simple: misinformation

mathematical proofs should debunk any notion that keyword density
this same document illustrates the unfortunate truth about keyword
collected documents (to help build a semantic library), we have little
chance to create formulas that would be helpful for true optimization

That said, keyword usage and targeting are only a small part of the
testing and get to see a huge number of search results and shifts
based on keyword usage tactics
When working with one of your own
sites, this is the process we recommend:
Use the keyword in the title tag at least once, and possibly twice
(or as a variation) if it makes sense and sounds good (this is
subjective, but necessary)
Try to keep the keyword as close to
the beginning of the title tag as possible
More detail on title tags

Keyword Density Myth
Example
If two documents, D1 and D2, consist of 1000 terms (l =
1000) and repeat a term 20 times (tf = 20), then a
keyword density analyzer will tell you that for both
documents Keyword Density (KD) KD = 20/1000 =
0
020 (or 2%) for that term
Identical values are
obtained when tf = 10 and l = 500
Evidently, a keyword
density analyzer does not establish which document is
more relevant
A density analysis or keyword density
ratio tells us nothing about:
The Conclusion:
Keyword density is divorced from content, quality,
semantics, and relevancy

The relative distance between keywords in documents
(proximity)
Where in a document the terms occur (distribution)
The co-citation frequency between terms (co-
occurance)
The main theme, topic, and sub-topics (on-topic issues)
of the documents
What should optimal page density look like then? An optimal page
