📌 Suitable for: Bloggers, marketers, SEO freelancers, affiliate site owners

1. Introduction

Keyword research is still the backbone of SEO—even in 2025.

Whether you're writing blog posts, optimizing an online store, or launching a YouTube channel, you need to know what your audience is searching for.

Enter: ChatGPT and Google Gemini—two powerful AI tools that can help you generate keyword ideas fast, validate trends, and save hours of manual work.

In this guide, you’ll learn step-by-step how to do keyword research using both tools. No fluff—just practical prompts, real examples, and actionable tips.

2. Tools You’ll Need

To get started, here’s your AI-powered SEO toolkit:

✅ ChatGPT (Free or Pro with web access)

✅ Google Gemini (via Search or Workspace)

✅ Google Trends or Keyword Planner (for validation)

✅ Optional: Ahrefs, SEMrush, or Ubersuggest

💡 Pro Tip: Use a Google Sheet or Notion doc to track your keyword ideas as you go.

3. Step 1: Start with a Seed Keyword

A seed keyword is your starting point—something broad like:

✅“home workouts”

✅“digital marketing tools”

✅“online casino Philippines”

These keywords help the AI generate longer, more specific variations.

Try this ChatGPT prompt:

"List 15 long-tail keyword ideas for 'home workouts' that are trending in 2025, preferably low competition."

4. Step 2: Use ChatGPT to Generate Variations

ChatGPT is amazing at spitting out keyword clusters and content angles. Just be clear with your intent.

💬 Sample Prompts:

✅“Generate 20 long-tail keywords for [topic] with informational intent.”

✅“List blog title ideas based on high-traffic keywords for [topic].”

✅“What keywords are relevant to [niche] in the Philippines?”

You can even ask it to create an FAQ list based on “People Also Ask” data.

5. Step 3: Use Google Gemini for Real-Time Search Trends

Gemini (formerly Bard) has access to live Google search data, so it’s perfect for surfacing trending queries.

Try asking Gemini:

“What are the top Google searches related to [keyword] in April 2025?”
“What are people asking about [topic] in the Philippines right now?”

You’ll get highly relevant, fresh keyword ideas—perfect for blog posts, shorts, or product pages.

6. Step 4: Validate Keywords Using Free Tools

Don’t just rely on AI suggestions—cross-check them.

Here’s how:

This helps you choose keywords with real demand and low competition.

7. Bonus Prompts for Keyword Gold 💰

Here are powerful ChatGPT/Gemini prompts you can swipe:

✅“Act like an SEO expert. List low-competition keywords in [niche] with high intent.”

✅“Generate question-based keywords for a blog about [topic].”

✅“Give me keywords that could rank for featured snippets.”

8. Expert Tips (from 17 Years of SEO Experience)

✅ Intent matters more than volume. A keyword with 100 monthly searches but high conversion is better than 10,000 clicks that bounce.

✅ Think like a human, not a bot. Keywords should match how people actually talk, especially with voice and AI search growing.

✅ Use AI for ideation, not validation. Always verify before building content around it.

9. Conclusion

AI tools like ChatGPT and Gemini have changed the game for keyword research—making it faster, easier, and more beginner-friendly than ever.

Whether you're building your first site or managing an SEO agency, these tools will help you uncover keyword gems and stay ahead of the competition.
