Hi, I am Navneet Singh, and I have been in the SEO industry for the past 12+ years. After working with numerous companies and multiple clients for keyword research and content optimization, I have gained complete knowledge of how important it is to choose the right keyword research tool.

After conducting in-depth testing combined with my personal experience, I have listed 21 keyword research tools (free+paid) to help you excel in your campaigns.

What are Keywords?

The majority of people use their laptops or phones to look for services, products, or simply general facts. The words users put into Google, Bing, or other search engines to find the information are called keywords.

For example, when you want to search for a nice coffee place, and you put “best coffee places in Chicago” or “most instagrammable cafes near me” on Google, in that case, you are putting keywords to find the information you want.

Your keywords are what landed you on this article as well!

We use keywords in our daily life, for every little search, yet completely unaware of the importance of it.

What is Keyword Research and Why is it Important?

Keyword research is the process of hunting down valuable and relevant search queries that users type into Google, Bing, or other search engines to look for products, services, and general information. No matter how hard you try, you won’t receive any traffic from Google if no one is looking for what you’re writing.

Therefore, keyword research is essential if you want to be seen, found, build brand recognition, and boost website traffic.

You can use various keyword research tools to explore relevant and popular target keywords that can help your website rank better on Google.

Let’s explore the different types of keyword research tools (free+paid) available in the following sections.

Before jumping into the article, I would briefly explain some important terms you must know to understand keyword research metrics.

  1. Seed Keywords: Seed keywords, main keywords, or head keywords are the starting point or building blocks of a keyword research process. For example, coffee, Seo, etc.
  2. Long-tail Keywords: These are the extended versions of the seed keywords—for example, types of coffee, what is Seo, etc.
  3. Search Intent: The main goal of the user while searching a particular query.
  4. Search Volume: It signifies the average number of monthly keyword searches.
  5. Keyword Difficulty: An estimation of how difficult it would be to organically rank on Google’s first page for the keyword.
  6. Cost-per-click (CPC): The money advertisers are willing to pay per every click on their website.
  7. PPC or Pay-per-click Competition: It signifies how competitive the keyword is for advertisers to promote products and services.
  8. SERP Analysis: Analyzing top-ranking web pages.
