The search engines use a number of factors when ranking a page within their index. They use a series of on-page and off-page factors. Of the on-page factors, Keyword Density becomes a key component.

A well optimized page will benefit both the user and the search engine spiders. Keyword density is one of the main contributors as to how users and search engines use your website. Keyword density is measured by taking key phrases and measuring the ratio of the phrases to the total number of search engine indexable words in a page. This includes the “invisible” content such as meta tags and image alt tags. Ideally pages should be between 400 and 600 words and have at least one important phrase on the page, repeated throughout, while keeping the page intelligible to readers.

When writing copy for your website, there are a number of ways to ensure that you utilize proper keyword density throughout your web pages.

Seven Ways to Improve Keyword Density
  1. Insert Keywords Into Page Titles – this pertains to the title tag that is commonly associated with the meta data of your site pages. You page titles should include keywords preferably near the beginning of the title for optimal effect. This helps communicate the subject matter of the page to the search engines and more importantly your users. The title also appears in the results pages of the search engines and is often bolded depending on the user’s search query.

  2. Insert Keywords into Headings – Include keywords in the heading of the page copy itself. Ensure that the main heading of your page uses heading tags with the "h1" heading tag considered to be the most important.

  3. Place Keywords in ALT Text – if you have images on your web pages, ensure that you place descriptive alt text on the image that is key word rich. Do not spam your ALT Tags.
