When doing keyword research, you should ensure you have the right tool. The best keyword research tool will streamline and simplify your workflow.

However, with so many keyword research tools out there, all claiming to be the best, it can be hard to choose the right one for you. To help you make the right choice, we have reviewed the top 5 tools to provide the best keyword research results. But before we dive into this, let’s see how we made our options.

How To Choose The Right Keyword Research Tool

There are several factors to consider when choosing a keyword research tool. These include:

Key Data

The only reason why you are using a keyword research tool is because you need important data. If a tool does not have data, such as the search volume, it will add no value to you. This is why you should only work with tools with data, such as:

  • Search volume
  • Traffic
  • Keyword difficulty
  • Competitor analysis

Source of Data

Where a tool gets its data from will determine its legitimacy. If it’s getting data from the wrong source, it will likely provide results with errors. The best keyword research tool should get its data from Google Search Console.

Ease of Use

SEO analysis can be complicated, especially for beginners. Understanding the data produced by these tools can be hard. This is why you should go for a tool that is easy to use and has simple functionalities.

Cost of The Tool

Keyword research tools are available at a wide range of prices, from free to hundreds of dollars. Others are paid but have a free trial period. From our review of the functionality of these tools, we realized that the best tools don’t come cheap. While the free tools may do basic keyword research, their features are limited.

Range of SEO Features

While it’s called a keyword research tool, it doesn’t mean that the only thing you should be able to do with it is keyword research. Some of the best tools have a wide range of features, making them a one-stop tool for your SEO analysis.
