How to Do Keyword Research in 5 Simple Steps (Using Free Tools)

Finding the right keywords isn’t just about chasing high search volumes; it is about understanding your audience’s language. If you are building a new blog or an e-commerce site, the foundation of your SEO strategy rests on how well you identify the phrases people type into Google.

In this keyword research tutorial, we are stripping away the complexity. You don’t need a $100/month subscription to find winning search terms. We will show you how to uncover profitable opportunities using entirely free tools in just five actionable steps.

Why Keyword Research Still Matters in the Age of AI

With Google’s Search Generative Experience (SGE) and AI-driven results, some claim keyword research is dead. They are wrong. While Google has become better at understanding “entities” and topics, keywords remain the primary signal of user intent.

Keywords tell you:

What your customers are looking for.
How competitive a specific niche is.
Which topics are trending right now.

Step 1: Brainstorm Seed Keywords and Topics

Before opening any tool, start with what you know. Seed keywords are the broad foundations of your niche. If you sell “vegan soap,” your seed keywords might be:

Organic skincare
Handmade soap
Cruelty-free beauty

Think about the “buckets” of topics your business falls into. Ask yourself: what questions do my customers ask during a sales call? What problems does my product solve?

Step 2: Use Google Suggest and “People Also Ask”

Google itself is the most powerful free keyword tool. It literally tells you what people are searching for in real-time.

Google Autocomplete

Type your seed keyword into the search bar but don’t hit enter. Google will suggest variations based on popular searches. These are gold for finding long-tail keywords.

Step 3: Leverage Free Keyword Research Tools

While paid tools like Ahrefs or Semrush are powerful, free tools can get you 90% of the way there. Here is a comparison of the best free options available today:

Tool	Best For	Key Feature
Google Keyword Planner	Commercial Intent	Provides accurate monthly search volume
AnswerThePublic	Question Keywords	Visualizes “Who, What, Why” queries
Ubersuggest (Free Version)	Competitor Analysis	Shows what keywords your competitors rank for
WordStream	Fast Suggestions	Simple list of related terms and competition levels
Google Trends	Seasonality	Shows if a keyword is growing or dying

Using Google Keyword Planner

To use this for free, you need a Google Ads account. You don’t have to run an active campaign—just skip the ad setup. Use the “Discover new keywords” feature to get specific search volume data and competition levels.

Step 4: Analyze Search Intent

This is where most beginners fail. If you target a keyword without matching the intent, you will never rank on page one. Google categorizes intent into four main types:

1. Informational: The user wants to learn something (e.g., “how to make soap”).
2. Navigational: The user wants to find a specific site (e.g., “Lush soap login”).
3. Commercial: The user is researching before buying (e.g., “best vegan soaps 2024”).
4. Transactional: The user is ready to buy (e.g., “buy lavender soap online”).

Pro Tip: Look at the top 3 results for your keyword. Are they blog posts? Product pages? Videos? You must create the same type of content that Google is already rewarding.

Step 5: Filter for Low-Competition “Long-Tail” Keywords

If you have a new website, you won’t rank for “shoes” or “marketing.” You need to find long-tail keywords—phrases that are 3-5 words long and more specific.

Instead of “SEO,” try “SEO tips for small local bakeries.” These have lower search volume but much higher conversion rates because the user knows exactly what they want.

How to judge competition for free:

Check the MOZ Bar: A free Chrome extension that shows the Domain Authority (DA) of sites in the search results.
Look for Forum Results: If Reddit or Quora threads are in the top 5 positions, it’s a sign that a well-optimized blog post can easily take that spot.

Putting it All Together: Your Keyword Map

Once you have your list, don’t just dump them on one page. Create a “Keyword Map.” Assign one primary keyword to each page of your site and 2-3 supporting LSI (Latent Semantic Indexing) keywords. This prevents “keyword cannibalization,” where your own pages compete against each other.

Final Checklist for Success:

[ ] Does the keyword have at least some search volume?
[ ] Do I have a realistic chance of outranking the current top 10?
[ ] Can I create content that is better or more current than what exists?
[ ] Does this keyword align with my business goals?

Keyword research is an ongoing process. Trends change, and new competitors emerge. By following this keyword research tutorial monthly, you’ll stay ahead of the curve and keep your organic traffic growing.

FAQs

What is the best free tool for keyword research?

Google Keyword Planner is generally the best for volume data, while AnswerThePublic is superior for finding question-based keywords.

How many keywords should I target per post?

Focus on one primary keyword and 3–5 related sub-topics or LSI keywords to maintain topical relevance.

What are long-tail keywords?

They are specific, longer phrases that users search for. They usually have lower volume but higher conversion rates and less competition.

Is keyword density still important for SEO?

No, “stuffing” keywords is penalized. Focus on natural placement in the H1, first paragraph, and subheadings.

How long does it take to rank for a keyword?

For new sites, it can take 3–6 months. For established sites with high authority, it can happen in days or weeks.

Should I target high-volume keywords only?

No. High-volume terms are often too competitive. A mix of low-volume, high-intent keywords usually yields better ROI.

Can I do keyword research without tools?

Yes, by using Google’s autocomplete, the “Related Searches” section at the bottom of results, and the “People Also Ask” boxes.
