What is Keyword research?

Keyword research is the basic process of identifying the popular search terms that people use on search engines like Google or social media pages like Facebook and Instagram. The basic idea behind keyword research is to know what the customer is looking for and tweak your offerings correspondingly.

In simple terms, without knowing what your customer is looking for, how will you optimize your website, market products, and services, and create content effectively?

Keyword research tells you the below details.

  • What is your customer looking for?
  • How and where is the customer searching for it?
  • How best you can present them with your product or service?

Once you identify the right keywords, you can use them in the content you develop to make sure it is ranked higher on the results page of search engines. This is one of the fundamentals of Search Engine Optimization (SEO) and helps you stay on top of your game.

Keyword research is not a one-time process though! You will have to periodically revisit the top keywords searched for and keep changing your SEO strategy accordingly.

Here is where a keyword research tool comes to help. Such tools constantly discover new and popular keywords and list them on their databases. They can tell you how good a keyword is, what other keywords are used by your competitor, and give you a list of well-analyzed keywords that would serve your purpose.

Using a keyword research tool to identify popular and right keywords helps your website or your content reach the right audience and get a higher ranking on Search Engine Results Pages (SERP).

Below is a list of top keyword research tools in the market right now. Compare their features and perks and use the one that fits your SEO needs.
