What Are Keyword Research Tools & Why Do They Matter?
Keyword research tools are online platforms that assist you in finding out what your audience is looking for online.
They display to you items such as:
- Search volume → number of individuals searching for a keyword
- Keyword difficulty → how difficult it will be to rank for it
- Related keywords → that may be easier to aim for
They operate by drawing information from search engines (such as Google or Bing) and examining what users are entering in the search box. Many tools also provide information on trends, user questions, and even competitors’ keywords.
