3. Alexa’s Keyword Difficulty Tool

Another keyword explorer within Alexa is the Keyword Difficulty tool. This tool allows you to search for keywords in two ways.

1. Enter a website to see keywords that are relevant to the existing site content. This helps you find terms that are relevant to your website’s content and products or services. The report includes a popularity score (that indicates how frequently the phrase is searched for) and a competition score (that shows how difficult it is to rank for the term).

Access this information via Site Overview by clicking “View all Keywords” on the easy-to-rank keyword report.

The report automatically adds filters to hide terms that are already driving traffic to your site and also those that exceed your ranking abilities.

To determine what keywords are within your ranking abilities, Alexa assigns a competitive power score to your site. If a keyword’s competition score is beyond your site’s competitive power, it will be difficult to rank for and therefore may not be the best keyword to target.

The report helps you find popular, low-competition keywords that would be relevant for your site, interesting to your intended audience, and within your ranking ability.

2. Another way to use the Keyword Difficulty tool is by searching for a target phrase (instead of a target website). When you enter a target phrase, the keyword finder provides a list of related keywords.

With the list of keywords, you can identify relevant terms to target on your site. To drill down into the information even more, add filters. Filters can set competition, relevance, and popularity ranges as well as filter out any keywords that already drive traffic to your site, allowing you to quickly find the best keywords to target in your content and SEO strategy.
