The term “Free keyword research methods” is one of the most searched queries by content creators(bloggers and YouTubers), especially beginners. It is searched 110000 times per month according to Ahref.

So I’m excited to show you my simple but very effective keyword research method for grouping related keywords and identifying content ideas for your blog. The best part—it’s 100% free using Google’s own keyword tools.

If you already have a blog or planning to start one, finding the right keywords to target is neccessary for attracting organic traffic from search engines. Which makes it very necessary to have a solid methodology for grouping keywords into related topics.

This approach has become a key part of my blogging strategy.

I’ll walk you through exactly how to use Google Keyword Planner to generate keyword ideas and organize them into conceptual content clusters or “hubs.”

1. Use Google Keyword Planner to Discover New Keywords

Our keyword research starts in Google Ads Keyword Planner (formerly Google Keyword Tool). It is totally free, you don’t need to spend a dime to use this tool. As long as you have a free Google account, you can sign in and access its powerful keyword data.

To get started, go to and click on Tools > Keyword Planner in the top right. This will open the keyword research interface.

From here, choose the Discover New Keywords option, click on Start with a website and enter your competitor’s website URL or a relevant keyword related to your niche. For this example, let’s go with “window cleaning services Miami” to research keywords around a hypothetical window washing business.

Google will analyze the site and return a huge list of keyword ideas, along with monthly searches for each keyword. Let it run for a few minutes until it returns the results.

Already you can see tons of window cleaning-related keywords, along with their average monthly searches and competition data. This info helps gauge demand and how hard it might be to rank for each term.

But things get even more interesting when we export the keywords…

2. Export Keywords into a Spreadsheet

Next is to export the keyword list out of Keyword Planner for further analysis.

Simply check the box next to each keyword you want to export or click “Select All” to grab them all. Then click the Download button at the top and choose Google Sheets.

Give your sheet a name like “window-cleaning-keywords” and let the export run.

After a minute or two, you’ll have a spreadsheet with one keyword per row including monthly searches and other metrics pulled straight from Keyword Planner. This makes it easy to sort, filter and work with the keywords.

Already you could start picking keywords from this list to target in your content. But we can take things even further by clustering semantically related keywords together into logical content groups.

3. Use AI to Cluster Keywords by Topic

This is where the real magic happens!

With our freshly exported keywords, we can leverage AI to automatically group related keywords together around potential content themes. This makes it incredibly easy to see the different types of pages and topics you should be creating content around.

My recommended AI tool for this is the Googl’s Gemini. Gemini utilizes cutting-edge AI to cluster keywords by topic with shocking accuracy. And you can try it for free!

To see Gemini in action:

  1. Head to via the Chrome browser. If you have a gmail account you already have access to Gemini. No credit card needed either.
  2. Once signed in, copy your entire list of keywords from the Google Sheet into Gemini’s text box.
  3. Enter a prompt like: “I have a website for a window cleaning service. Can you group these keywords so I know which pages to create content around?
  4. Hit Submit and let Gemini work its magic!

In 1-2 minutes, Gemini will return your list of keywords neatly sorted into logical groups reflecting potential content themes.

Going by our “window cleaning service” example, as you scan through, you’ll notice Gemini picked up on key services like:

  • Core window cleaning
  • Pressure washing
  • Soft washing
  • Location pages like “window cleaning Miami”

This makes it blatantly obvious which pages you need on your site and the exact keywords that should go on each one.

Gemini even suggests:

Have one dedicated page for your core window cleaning services using the keywords in Group 1. Create another page for pressure washing services using Group 2 keywords…

I mean, it straight up tells you exactly what content to create and which keywords to optimize each page around. This perfectly sets up your site architecture before writing a single word!

And it’s all generated automatically by AI in seconds.

But we aren’t done yet…

4. Uncover Long-Tail Keywords

Now we can dig even deeper to uncover ultra-targeted long-tail keywords on each topic. These are more specific keywords with lower search volume but far less competition.

For example, something like:

  • window cleaning services for highrise apartments
  • how much does pressure washing a house cost

Since Gemini did such an awesome job clustering our main keywords, we can prompt it again to surface long-tail variants around each group:

Can you give me a list of long-tail keywords for each of these groups?

    And boom—it returns pages of fresh, untapped long-tail keywords that perfectly fit with each content cluster.

    I can literally see specific blog post ideas like:

    Benefits of Soft Washing for Delicate Surfaces” and “Pressure Washing Safety Tips” jump right off the page. It’s like being handed a list of winning titles I know will attract search traffic if I write posts around them.

    This saves SO much guesswork and lets you create crazy relevant, search-friendly content right from the start.

    So to quickly recap:

    1. Use Google Keyword Planner to export a big list of keywords
    2. Feed keywords into Gemini to automatically group them into content clusters
    3. Uncover targeted long-tail keywords for each cluster

    Rinse and repeat this for any niche, and you’ve got a formula to see the perfect content map for your entire site.

    From here, you can start writing posts, guides and services pages optimized around each keyword group. Ranking will get easier and easier over time as you nail search intent with laser targeted content.

    Obviously there’s more complexity when it comes to on-page optimization, backlinks, etc. But having the RIGHT keywords and content mapped out from the start makes the whole process 10X smoother.

    So if you’re struggling with keyword research or deciding what content to create, give my 4-step method a try. Gemini especially can work magic organizing your site structure in minutes.
