Step-by-Step Guide: How to Use Free AI Tools for Keyword Research in 2025

Step 1: Define Your Niche and Goals

Before diving into tools, ask:

What’s your target audience?
What problems do they want solved?
Are you optimizing for traffic, conversions, or brand awareness?

Example: If you run a fitness blog, focus on keywords like “home workout routines for beginners” or “low-carb meal plans.”

Step 2: Leverage Google Keyword Planner (Free)

How to use:

Go to Google Keyword Planner (free with a Google Ads account).
Enter a seed keyword (e.g., “yoga for flexibility”).
Filter results by location, device, and average monthly searches.

Pro tip: Use the “Discover new keywords” tab to find long-tail variations like “yoga poses for tight hamstrings.”

Step 3: Try Ubersuggest’s Free Tier

How to use:

Visit Ubersuggest and enter a keyword.
Check the “Keyword Overview” for SEO difficulty, search volume, and content ideas.
Explore the “Top Pages” section to see what competitors rank for.

Example: Searching “vegan protein sources” might reveal related keywords like “plant-based protein powders” or “high-protein vegan meals.”

Step 4: Use ChatGPT for Creative Keyword Ideas

How to use:

Ask ChatGPT prompts like:
- “What questions do beginners ask about [your niche]?”
- “List 10 long-tail keywords for [product/service].”

Refine the output by adding location-based modifiers (e.g., “best hiking trails in Colorado”).

Note: While ChatGPT isn’t a dedicated keyword tool, it excels at generating content-aligned keyword ideas.
