Often times you hear people refer to “keyword density” when talking about search engine optimization.
Keyword density refers to how often a phrase is mentioned throughout the content of a web page in contrast to the total number or words within the page.
Search engine optimization specialists who offer professional SEO services generally concede that a density of between 2% and 5% is optimal when completing the on-page optimization of a website. What that means is that your targeted keyword phrase for that web page should make up between 2% to 5% of the total page text content.
However with the changes that Google has made over recent years with regards to Latent Semantic Indexing, keyword density for targeted keyword phrases has become more difficult to incorporate successfully.
Latent Semantic Indexing
Latent Semantic Indexing (also referred to as LSI) was introduced into Google’s algorithm a few years ago.
Similar to synonyms, Google created their own database of “key” word phrases that are synonymous or related to one another. Google based their list on the search queries of internet users and the phrases that website owners used within their websites to describe the same “key” word phrase.
When synonymous keyword phrases (also called “related” or “stem” phrases) are used within a web page they are considered to be the same as using the targeted keyword phrase and changes the dynamics of “keyword density” within a web page.
Most keyword density tools however, are not equipped to determine successfully what phrases Google considers synonymous or related to other phrases; therefore these tools cannot actually determine the keyword density accurately.
The result can leave a website owner either with an under-optimized (low keyword density) web page or an over-optimized (high keyword density) web page; either way the page is not likely to obtain high natural rankings in the search engine listing results.
Identifying Google’s Synonymous Phrases
One easy way to determine which phrases Google finds synonymous is to use Google’s advanced search operators when completing a search query. Below is an easy example to help get you started.
Google’s Synonymous Phrases for “Car”
To find the synonymous phrases for the word car, simply go to Google.com and in the search box type in the tilde (~) and then the word “car”. It should look like this:
Press the search button.
When the results are returned, you will see various words that are bolded within the various search engine results. These bolded words are the phrases that Google has indicated as being synonymous or related to the word “car”.
Some of the phrases that you will see are:
- California Association of Realtors
Synonymous Phrases, Related Phrases & Acronyms
As you can see there are some phrases that are not truly “synonymous” with the word car, but are more or less related. You can also see that “CAR” is the acronym for California Association of Realtors, not a synonym for the phrase car.
To utilize keyword density effectively in your search engine optimization efforts, it is important that:
- You review these related phrases and ensure that any phrases that are semantically related to the phrase you are targeting from your keyword research will also be utilized in your text content.
- It is equally important to ensure that you do not add in any phrases that are not related to your text content, just because they show up within your LSI research
