Free Keyword Research: A Simple Workflow That Works

---

By Justin Zwick for Free Micro Apps · Published September 20, 2026

Free keyword research is mostly about understanding how real people describe their problem, and you can do a lot of it without paid tools.

Keyword research sounds like something that needs expensive software and a spreadsheet the size of a city. For most small sites, it doesn't. A simple, repeatable workflow with free tools will get you most of the value. This article walks through one, using tools on Free Micro Apps.

Why keyword research never runs out of new ideas

Search behavior keeps changing, which is why keyword lists go stale. Google said in a 2017 post on its official blog that 15% of the searches it sees every day are ones it has never seen before. That's a good reason to revisit your keyword research regularly rather than treating it as a one-off job.

Step 1: Start with your customer, not with tools

Before opening any tool, write down:

• What you offer. Products, services or topics you cover.
• Who it's for. Their situation, not their demographics. "People who just bought their first home and need a reliable electrician" is more useful than "adults aged 30–45".
• What they'd type into a search box. Brainstorm ten to twenty phrases. Include questions ("how do I…", "what is…", "best way to…") and problems ("faucet dripping at night").

This list is your seed list. Tools will expand it, but they can't replace your understanding of your customers.

Step 2: Expand your list with suggestions

Take each seed phrase and run it through the Keyword Suggestion Tool. It returns related searches, which often reveal how people actually phrase things.

As you go, note phrases that:

• Clearly match something you offer
• Describe a specific need or question
• Use words your customers use, which aren't always the words you'd use

Ignore phrases that are only loosely related. A long list of irrelevant keywords is worse than a short list of good ones.

If you work on video content, the YouTube Keyword Extractor shows the tags used on a given video, which can spark more ideas.

Step 3: Group keywords into topics

This is the step most people skip, and it's the one that makes everything else easier. Group similar phrases together. Each group usually becomes one page.

For example, "how to fix a dripping faucet", "faucet dripping when turned off" and "stop a leaky tap" all belong on one page about fixing a dripping faucet. You don't need a separate page for each phrase.

The AI Keyword Cluster Ideas tool can help by suggesting groupings and related subtopics. Review its suggestions with your own judgment; you know your audience better than any tool.

Step 4: Think about intent

For each group, ask what the searcher wants:

• To learn something (informational): a guide or explanation fits.
• To compare options (commercial): a comparison or buying guide fits.
• To buy or book (transactional): a product or service page fits.
• To find a specific site (navigational): usually your homepage or a key page.

Matching the type of page to the intent matters as much as the words themselves. A product page rarely ranks for "how does X work", and a long guide rarely ranks for "buy X near me".

A quick way to check intent is to search the phrase yourself and look at what's already ranking. If the results are all guides, write a guide.

Step 5: Map each group to a page

Create a simple table:

Topic group	Main phrase	Intent	Page
Dripping faucet	how to fix a dripping faucet	Informational	New guide
Emergency plumber	emergency plumber [city]	Transactional	Service page

Each group gets one page. If two groups point to the same page, consider whether they're really one group. If one group has no page, that's a content gap you can fill.

Step 6: Write for people, then check the page

Write the page to genuinely answer the need. Use the main phrase naturally in the title, the main heading and the opening paragraph, and use related phrases where they fit.

Then check how the finished page uses its terms with the Keyword Density Checker. The goal isn't to hit a particular percentage. There's no magic number. Instead, use it to spot problems:

• If your main topic barely appears, the page may not be clear about what it covers.
• If one phrase is repeated constantly, the text probably reads awkwardly and should be rewritten.

The Meta Tags Analyzer shows whether your title and description reflect the topic, and the AI Meta Title Generator and AI Meta Description Generator can give you drafts to edit.

Step 7: Track where you rank

After publishing, give search engines some time, usually weeks, then check where your page appears for its main phrases with the Keyword Position Checker. Record the results and check again monthly.

If a page ranks on page two or three, it often just needs improving: answer the question more completely, add examples, improve the title, or link to it from related pages on your site.

A note on search volume and difficulty

Paid tools estimate how many people search each phrase and how hard it would be to rank. Those numbers can be helpful but they're estimates, and they're often unreliable for small, specific phrases. For a small site, it's usually smarter to target specific phrases that clearly match your offer, even if they're searched less often. They tend to bring visitors who actually want what you have.

The Keyword CPC and Volume Checker can give you a rough sense of interest for a phrase when you want one.
