Ecommerce Experts agree, that Google pays attention to the word saturation when it runs the website ranking. It is assessing each page based on the words that are being used the most [that is, as we know, one of many factors of seo marketing, yet very important one].
If your page contains 10 words ‘coffee’, Google is assured this particular page relates to the topic of coffee. It will also be sending the traffic from the relevant search results towards your page. The semantic keywords [all other smaller words contained within your page] will give Google more clues about the particular topic around the coffee: is about brewing techniques, baking a coffee cake, or maybe removing a coffee stain from your table cloth?
Knowing if your page is optimized with the right words, will help you attract the most relevant traffic from the search results. Hence the word cloud for the support!
