ChatGPT, an AI tool that supports keyword research

With the right prompts, ChatGPT can generate seed keywords, expand long-tail keywords, group keywords by topic and analyze search intent in a short time.

When you combine ChatGPT with dedicated SEO tools to check search volume and competition, an SEO specialist can cut keyword research time considerably while keeping the content strategy on track.

Advantages of ChatGPT as an AI tool for keyword research

ChatGPT is one of the AI helpers that make keyword research faster and easier. Instead of depending entirely on complex SEO software, ChatGPT shortens analysis time and helps shape your content direction from the very first step.

• Saves research time, especially for people new to SEO or content writing

• Its data is not real time, so it can miss the latest search trends
• It does not give key metrics such as search volume, competition or actual CPC
• It cannot judge SEO difficulty from real SERP data
• You need to pair it with a dedicated tool such as Ahrefs or SEMrush to verify results and make accurate decisions

ChatGPT is inexpensive to use for keyword research. The free version covers the basics, such as generating keyword ideas and analyzing search intent. For heavier use, ChatGPT Plus costs about 20 USD per month, which suits a professional working on SEO alone. Companies can choose the Team or Enterprise plans for large-scale keyword research and smoother teamwork.

How to use ChatGPT to find keywords

To research keywords well with ChatGPT, start from your main seed keyword, then write prompts in the Role – Task – Context – Format structure. A clear prompt tells ChatGPT its role, its goal and the output format you want, so it can suggest related keywords, LSI terms and long-tail keywords, or group them by search intent, in an organized way. 

For example, say the seed keyword is "ắc quy ô tô" (car battery). You could use a prompt like: "You are an SEO expert. Create a list of long-tail keywords and sort them by intent for the topic car battery, in a table with keyword and intent columns."

ChatGPT will return keyword groups such as: buy a car battery, which car battery is good, car battery prices by brand, and so on.

Keywords Everywhere is a Google keyword research tool built into your browser. It shows search volume, CPC and competition right next to the Google results. That way you can analyze keywords without switching tools, which saves time and keeps you close to search trends.

• It is easy to install and use, and suits beginners and professional marketers who want to analyze keywords quickly while browsing.

Disadvantages

Keywords Everywhere also has some limits to note:

• It is not completely free; you need to buy credits to access search volume and CPC data.
• Some data may be out of date or not fully accurate, so you need to verify it with other tools.
• Heavy use burns through the credits you bought quite fast, which gets expensive if you do not keep an eye on it.

Cost

Keywords Everywhere is a browser extension that shows keyword search volume, CPC and competition. The paid version works on credits, at about 10 USD for 100,000 credits, and each keyword lookup uses one credit. It supports many platforms and lets you export data flexibly.
