How to Do Basic Keyword Research for Free in 2025?

Let’s talk about keyword research — the not-so-secret ingredient behind every solid SEO or content plan. It’s basically how you figure out what people are typing into Google before they land on your website. Without it, you’re just guessing what your audience cares about… which usually means writing great content that no one actually sees.

Now, a lot of folks assume you need fancy tools like Ahrefs or SEMrush to do keyword research properly. Nope. Totally not true. You can do it for free — yes, even in 2025. You just have to know where to look and how to use what’s already out there.

So, grab your metaphorical shovel — we’re digging for keywords.

Why Bother With Keyword Research Anyway?

Imagine opening a restaurant and not knowing what people in your neighborhood like to eat. You might serve sushi when everyone’s craving pizza. Keyword research fixes that problem for your website.

Here’s why it matters:

• You understand what your audience actually wants (and stop writing random stuff).
• You discover where the traffic is hiding — those juicy search terms that can bring visitors your way.
• You learn how to optimize your content so Google actually shows it to people.
• You can plan smarter — knowing which blog posts, FAQs, or landing pages are worth your time.

Without this groundwork, even the most beautifully written post will just sit there… lonely… on page six of Google.

Step 1: Start With Seed Keywords

Think of seed keywords as your starting ingredients — basic words related to your topic, product, or service. They’re simple, broad, and usually obvious.

How do you find them? Easy:

• Write down a few main things your business or blog is about (5–10 ideas max).
• Peek through your own website — what words keep showing up in your content?
• Head to Google and start typing something in — those autocomplete suggestions? Goldmine.

Example:
Say you’ve got a fitness blog. Your seed keywords might be:

• “home workouts”
• “healthy meal plans”
• “weight loss tips”

Nothing fancy yet — just a starting point.

Step 2: Use Free Keyword Research Tools (Yes, Free)

Alright, now let’s expand those ideas. You’ve got your seeds — now plant them into these free tools:

• Google Keyword Planner: You’ll need a Google Ads account, but it’s free. It shows search volume, keyword suggestions, and competition level.
• Google Search Console: A hidden gem that shows what keywords your site already ranks for and how often people click on them.
• Ubersuggest (Free Version): Neil Patel’s tool gives you related keywords, search volume, and difficulty scores — enough to get started.
• AnswerThePublic: Type in a keyword and it’ll show all the questions people ask about it — great for blog ideas and long-tail phrases.
• Google’s “People Also Ask” box: Seriously underrated. Type your keyword into Google and scroll down — those expandable questions? Copy them. Real searches from real users.

Step 3: Analyze What You Find

Now you’ve got a long list of keywords, but not all of them are worth chasing. Some are too competitive, some don’t get enough searches, and some might just be irrelevant.

Here’s what you want to look at:

• Search Volume: How many people are searching that word or phrase every month?
• Competition: If you’re just starting out, aim for low-to-medium competition keywords.
• User Intent: Why are people searching it? Are they looking for info, trying to buy, or just browsing?
• Relevance: Does it actually fit your content and business goals?

And yeah — free tools give rough estimates, but that’s fine. You’re not running NASA’s SEO program; you just need direction.

Step 4: Go Long (as in Long-Tail Keywords)

Long-tail keywords are more specific, less competitive search phrases. They don’t bring massive traffic, but they bring the right traffic — people closer to taking action.

Examples:

• “yoga” → “morning yoga routine for beginners”
• “laptop” → “best budget laptop for students 2025”

How to find them:

• Use Google autocomplete — keep typing and see what pops up.
• Check the “related searches” section at the bottom of results.
• Explore tools like AnswerThePublic, Reddit, Quora, or niche forums.

These longer phrases often have lower competition and higher conversion potential — they’re like hidden gems most people ignore.

Step 5: Organize Your Keywords Like a Pro

You’ve got a list now — maybe even a long one. Time to organize it before your brain explodes.

Here’s a simple way:

• Create a spreadsheet.
• Make columns for keyword, search volume, competition, and intent (informational, commercial, transactional).
• Group similar ones together under themes.

This helps you plan content efficiently — blog posts, landing pages, FAQs — all aligned with your SEO goals. Plus, it keeps you from accidentally targeting the same keyword on multiple pages (a sneaky mistake called keyword cannibalization).

Step 6: Keep an Eye on Things

Keyword trends don’t stay still. What people searched last year might be old news now. So every few months, do a quick refresh:

• Check Google Search Console for new queries bringing traffic.
• Hop on Google Trends to spot rising topics.
• Update your content with fresh keywords when needed.

Think of SEO like a garden — if you don’t water it, it stops growing.

Wrapping It Up

Keyword research doesn’t have to cost you a fortune or give you a headache. You just need curiosity, patience, and a few free tools. Start with your seed keywords, expand with Google and friends, find long-tail phrases that actually match what people want, and keep things organized.

Do this consistently, and you’ll not only bring more people to your site — you’ll bring the right people. And that’s what SEO’s really about.
