Keyword Density Analysis Tool
Keywords are the words that users type into a search engine, to define the nature of what they are looking for. Keyword Density is a representation of the number of times that a specific phrase of words, or keyword phrase, occurs on your site in proportion to the number of other words on the site.
Here is an example:
Let's assume that the previous paragraph of text represents our entire webpage, and the keyword phrase we're
searching for is simply "keyword" (it is worth noting, however, that a keyword phrase may be many
words instead of just one). In the previous paragraph, there were:
- • 3 occurances of the word "keyword" (including plurals)
- • 55 total words in the paragraph
- • An overall density of roughly 5.5% (3/55, times 100 to get the %)
Feel free to utilize this tool, provided by SEOChat.com, to check the density of common word phrases on the web page that you are trying to optimize for the search engines. Though it's a fairly rudimentary algorithm for determining keyword density, it should meet your needs until we finish our new suite of free SEO tools.
UPDATE!
In response to requests from several of our users, we'd like to elaborate on the differences between the
SEOChat.com Keyword Density Analyzer and our own upcoming one, still in development. Their tool,
featured below, merely collects the number of instances of a word (or any string of two or three words in
a row, if you choose that option), and returns a response. The Service SEO Keyword Phrase Saliency Calculator,
codenamed "Keepsake™" in reference to its acronym (KPSC), is a bit more complex.
Service SEO's Keepsake™ tool starts with strings of between three and five words from a document, utilizing a process not entirely unlike that employed by the tool below. However, before making a determination as to what words are relevant in context to each other as a phrase, all of the "stop words" are culled from the body of text. Stop words are words that are useful to human beings, grammatically, but that have no real relevance to the subject matter of the document: definite and indefinite articles, pronouns, prepositions, conjunctions, etc.
After collecting these more selective keyword phrases that do not include any stop words (or any words less than five characters in length at all, to minimize the inclusion of acronyms), the phrases are then weighted against all other pages crawled on the website to determine their level of "keyword phrase saliency" against the corpus of documents as a whole. This means two things: first, that the more content there is on a website, the more accurate the tool will be; second, that the terms most unique to any given page-- the ones most relevant to its specific application in context to the website at large-- will float to the top of the list.
This is a very exciting project for all of us, and it fits into a much larger framework that we believe will help usher in the coming era of the Semantic Web with its contributions to our overall ontologically-oriented goals. A simple for-instance: one of the tools we'll be offering in conjunction with the rollout of the free version of Keepsake™ will be a commercial counterpart that generates these salient terms automagically, and places them in relevant locations on the pages of your website: in the title, heading, and meta tags; in the alt and title attributes of images and links, respectively; in URLs, fashioned as search-engine-friendly "URL slugs", etc.
