Keyword Strategy

Performing comprehensive keyword research is one of the most important steps for optimizing your website and content for search engines. By understanding what audiences search for and optimizing correctly for relevant keywords, you can improve organic visibility and drive more qualified traffic to your site.

In this post, we’ll explore various techniques for conducting keyword research, including leveraging ChatGPT to expand your keyword list. We’ll also discuss how to evaluate keywords and incorporate the winners into your content and site structure.

Generate Seed Keywords

To kick off your research, brainstorm a list of broad “seed keywords” related to your business, products, or services. These can include things your target customers might search for when interested in your niche.

AI SEO: ChatGPT for Keyword Research

Providing your seed keywords to ChatGPT allows the model to suggest related longtail keywords based on its vast database of search trends and questions. The AI can help uncover keyword opportunities you may have otherwise missed.

Evaluate Keywords Effectively

Once you’ve generated a list, identify the true potentials by checking search volume and competitiveness using free tools like Google Keyword Planner. Aim for keywords with decent monthly search numbers and lower difficulty.

Optimize Structures and Content

Incorporate your highest-potential keywords naturally throughout your site, especially in:

  • Page titles
  • H1 and H2 headers
  • Opening and closing paragraphs
  • Image alt text

Ensure each page covers the common topics and questions related to your targeted keywords as seen on top-ranking pages.

Prioritize Long Tail Keywords

Specific, lower-competition keywords tend to be easier to rank for while still drawing good organic traffic. Consider their balance of relevance, volume and difficulty when building your strategy.

Monitor Performance and Refine

Track key metrics like traffic, rankings and bounce rates over time. Be willing to refine your keyword list as needed based on what is or isn’t performing well for your users. Optimization is an ongoing process.

With the right keyword research approach, your content can rank for the questions most relevant to your target audience. ChatGPT and diligent tracking make the process more effective.

Keywords vs Entities

Entities and keywords are both important concepts in SEO, but they serve different purposes and have distinct characteristics:

What is an Entity

An entity is a more comprehensive and broad concept. It can refer to a wide range of things, such as people, places, organizations, products, and more.

Entities are typically real-world objects or concepts.

In SEO, entities often include specific brands, companies, products, and well-known figures.

Search engines like Google use entities to understand the relationships between different elements on the web, helping to provide more accurate and relevant search results.

What is a Keyword

A keyword is a specific word or phrase that users enter into search engines to find information on a particular topic.

Keywords are more focused on the language and terms that people use in their search queries.

In SEO, keywords are crucial for optimizing content and making it discoverable in search results.

Keyword research is the process of identifying the words and phrases that are relevant to your content and that people are likely to search for.

Keyword Research Tools

Free keyword research tools are essential resources for anyone looking to improve their website’s visibility in search engine results. These tools help you identify the most relevant and high-traffic keywords for your content.

Some of these free AI SEO tools for keyword research use Generative AI, and other use Machine Learning and Deep Learning directly or indirectly (by gathering data from Google). 

By using free keyword research tools, you can:

ChatGPT and the volume of keywords

ChatGPT and similar AI models, like GPT-3.5, are indeed trained on a large corpus of web data and can assist in keyword-related tasks. However, there are some important considerations:

Keyword Identification

ChatGPT can help identify keywords within a piece of content. It can understand the language and context of the text, which can be valuable in suggesting relevant keywords.

Keyword Summation

While ChatGPT can identify keywords, it may not be the most efficient tool for summing up keywords and providing keyword volume. Summing up keywords to determine their search volume typically involves aggregating data from search engines, which is better done using specialized keyword research tools.

Common Keywords

ChatGPT is trained on a diverse dataset, and it can suggest keywords that are commonly used on the web. However, it’s not guaranteed that the keywords it suggests are the ones with the highest search volume. The popularity of keywords can vary by topic, region, and over time, so using specialized SEO tools to access search volume data is recommended for accuracy.

In summary, ChatGPT can assist in identifying keywords within content and offer insights into common keywords, but for more accurate keyword volume data and keyword summation, it’s advisable to use dedicated SEO keyword research tools or services. These tools are designed to provide specific keyword metrics and can help inform your SEO strategy effectively.


AI, such as ChatGPT, has undoubtedly become a valuable asset in SEO and keyword research. While it can assist in identifying keywords and understanding user intent, specialized AI SEO tools remain essential for in-depth keyword analysis and tracking search volume. By combining the power of any of these Free AI SEO tools for keyword research, we can refine our content strategies and improve our online visibility effectively.
