How to Do Keyword Research for Free – Step-by-Step Guide

Published: 6 Sep 2026

You can do keyword research for free. Just use four tools: Google autocomplete, the “People Also Ask” box, Google Trends, and Google Keyword Planner. These tools show you real words people search for. They also show how many people search each word. Best part? You pay nothing.

Do you want more people to find your website? Then keyword research is your first step. It is not hard. It just takes a little time. Let’s walk through the full process, one step at a time.

What Is Keyword Research?

Keyword research means finding the exact words people type into Google. You use these words in your content. This helps more people find your website. It also helps you pick topics that are not too hard to rank for.

Think of it like this. A shop owner picks a good location before opening a store. Keyword research is the same idea. You pick the right words before you write. This way, your content lands in front of the right readers.

Why Free Tools Work Well for Beginners

Many beginners think they need paid tools to succeed. This is not true. Free tools give you real data straight from Google. This is the same company that runs the search engine. So the data is accurate and useful.

Paid tools do offer extra features. But they are not needed when you are just starting out. Save your money. Use free tools first. You can upgrade later, once your site grows.

Step 1: Use Google Autocomplete

Open Google. Type your topic. Do not press Enter. Google will show you suggestions right away. These suggestions are real searches from real people.

Example: Type “how to start freelancing.” Google may suggest “how to start freelancing with no experience” or “how to start freelancing in Pakistan.” Both are free keyword ideas. You just found them in ten seconds.

Try this with five or six topics. Write down every suggestion you see. Within a few minutes, you will have a long list of keyword ideas, all for free.

Step 2: Check “People Also Ask”

Search your keyword on Google. Scroll down. You will see a box called “People Also Ask.” You will also see “Related searches” at the bottom. Both boxes give you free keyword ideas.

Quick tip: Click on any question in “People Also Ask.” More questions will pop up below it. Keep clicking. You will get even more ideas, all for free.

These questions are gold for your content. They tell you exactly what your readers want to know. Use them as your article headings. This makes your content match real search intent.

Step 3: Try Google Keyword Planner

Google Keyword Planner is free. You only need a Google Ads account. You do not need to run any ads. This tool shows you:

How many people search a keyword each month
How hard it is to rank (Low, Medium, or High)
New keyword ideas you did not think of

Paste your keyword list into this tool. It will show you which words are worth writing about. Look for keywords with decent searches and low competition. These are your best options as a beginner.

Step 4: Check Google Trends

Google Trends shows you if a topic is growing or fading. This helps you decide if a topic is still worth your time.

For example, a topic like “AI tools for writing” is growing fast right now. A topic like an old app that nobody uses anymore may be fading. Google Trends helps you spot this difference in seconds.

Free Tools at a Glance

Tool	Best For	Cost
Google Autocomplete	Quick keyword ideas	Free
People Also Ask	Real reader questions	Free
Keyword Planner	Search volume and competition	Free
Google Trends	Rising vs fading topics	Free

Use all four tools together. Each one fills a gap the others miss. This gives you a full picture before you write a single word.

How to Organize Your Keywords

Do not just collect keywords and forget them. Put them in one place. A simple spreadsheet works best. Add these columns:

Keyword
Search volume
Competition level
Status (written, pending, published)

This keeps your work organized. You will always know what to write next. You will also avoid writing about the same topic twice.

My Real Experience With This Method

I always start with my main keyword. I type it into the Google search bar first. Then I check the “People Also Ask” box. This box shows me questions real people ask about that topic.

I also use the Ahrefs browser extension. It shows me keywords that are closely related to my topic. Between Google’s own suggestions and this free extension, I get a solid list of keyword ideas. I do this before writing every article, and it always saves me time.

Mistakes Beginners Make

Looking only at search numbers. A high number does not help if the competition is too tough for a new site.
Picking keywords that are too broad. “SEO tips” is hard. “SEO tips for small shops in Faisalabad” is easier.
Ignoring what the reader wants. If someone searches “how to,” give them steps. Don’t give them a sales pitch.
Never checking Google Trends. Writing about a fading topic wastes your time and effort.
Not organizing keywords. Without a list, you forget good ideas and repeat old topics.
