These tools analyze and provide data on keyword usage across the internet, helping you understand the search volume, competition, and even seasonal trends of specific keywords. They are instrumental in finding out which keywords are widely used in your industry or niche and how you can rank higher for those keywords. 

A keyword research tool is a compass guiding your SEO and content marketing strategies, pointing you toward the keywords that have the potential to increase your visibility on search engines and attract more traffic to your website.

How to choose the right keyword research tools

Choosing the best keyword research tools requires careful consideration of your specific needs and resources. Here are a few aspects that you should consider. 

  • Your goals: What are you trying to accomplish? Are you looking to boost organic traffic, target specific geographic regions, or are you after long-tail keywords that have low competition? Different tools have different strengths, so you’ll want a tool that aligns with your objectives.

  • Precision: The accuracy of the data the tool provides is vital. You don’t want to base your strategy on incorrect information. Look for tools that offer up-to-date and comprehensive data.

  • Usability: The tool should be user-friendly and intuitive. If it’s too complicated, you might end up wasting time figuring out how to use it instead of doing your keyword research.

  • Price: Consider your budget. Some keyword research tools can be quite pricey, but there are also affordable options that offer good value for money. Remember, the most expensive tool isn’t necessarily the best one for your needs.

  • Features: Look at the additional keyword research features the tool offers. Some tools provide keyword suggestions, SERP analysis, rank tracking, and more. These extra features can significantly enhance your SEO strategy.

  • Customer Support: Good customer service can be crucial, especially if you’re new to SEO. Look for tools that offer robust support, whether it’s through tutorials, webinars, or direct assistance.

Remember, choosing a keyword research tool depends on your unique circumstances. So, don’t rush your decision. Take the time to try out different tools—most offer free trials—until you find the one that fits your needs perfectly.

Can you use AI for keyword research?

AI is a powerful tool for keyword research. The advancement in artificial intelligence, especially ChatGPT, has brought an evolution in SEO. 

AI algorithms can efficiently analyze massive amounts of data, uncovering patterns and insights that may be difficult for humans to discern. This data can include search trends, user behavior, and semantic analysis—all critical factors in identifying high-performing keywords. 

However, keep in mind that while AI can provide valuable insights, the strategic application of this information still requires human judgment and expertise.

One of the most powerful AI tools for keyword research is ChatGPT. It’s a great way to build a topical authority around your niche. Here’s a simple way to use this tool. 

Let’s say you want to rank for the keyword “Best Gym Exercises”. You can type in a prompt like this:

Then ChatGPT will spit out a ton of keywords that you can put in your content calendar.
