Keyword research is the foundation of any successful SEO strategy. It tells you what your potential customers are actually searching for — and gives you a roadmap for the content you should be creating.
The good news is you don’t need an expensive subscription to get started. This guide walks you through how to do effective keyword research using free tools and a bit of strategic thinking.
What Is Keyword Research and Why Does It Matter?
Keyword research is the process of finding the words and phrases people type into search engines when looking for products, services, or information related to your business.
When you know what your audience is searching for, you can create content that matches those searches — which means Google is more likely to show your pages to the right people at the right time.
Without keyword research, you’re essentially guessing what to write about. With it, every piece of content you create has a purpose and a real chance of bringing in traffic.
Step 1: Start With What You Know
Begin by listing the topics that are most relevant to your business. Think about:
– What services or products do you offer?
– What problems do your customers come to you with?
– What questions do you get asked most often?
For example, if you run a digital marketing agency, your seed topics might include: SEO, social media management, content marketing, Google Ads, website design.
These broad topics are your starting point. From here, you’ll go deeper.
Step 2: Use Google’s Free Tools
Google itself is one of the best free keyword research tools available.
Google Autocomplete: Start typing a topic into Google’s search bar and watch the suggestions that appear. These are real searches people are making. Try variations like “how to,” “best,” “what is,” and “for small business.”
People Also Ask: When you search for something, Google often shows a “People Also Ask” box with related questions. Each of these is a potential keyword and blog topic.
Related Searches: Scroll to the bottom of any Google results page. The “Related searches” section shows you additional keyword variations people use.
All of this data is free, real-time, and based on actual user behavior.
Step 3: Use Free Keyword Tools
A few free tools give you search volume estimates and competition data:
– Google Keyword Planner — Free with a Google Ads account. Shows monthly search volume and competition level. Use it in “Discover new keywords” mode.
– Ubersuggest (free tier) — Enter a seed keyword and get related keyword ideas with volume, difficulty scores, and content suggestions.
– AnswerThePublic — Visualizes questions, comparisons, and prepositions people search around any topic. Great for finding long-tail angles.
– Ahrefs Webmaster Tools (free) — If you verify your own site, you get access to keyword data for the pages you already rank for.
Step 4: Focus on Long-Tail Keywords
Long-tail keywords are longer, more specific phrases — usually three words or more. They have lower search volume than broad keywords, but they’re far easier to rank for and attract higher-intent visitors.
Compare these two:
– Broad: “SEO” (extremely competitive, millions of searches)
– Long-tail: “how to do SEO for a small business website” (lower competition, very specific intent)
For a small business or a newer website, long-tail keywords are where you should focus 80% of your effort. You’re not competing with Moz or HubSpot — you’re targeting the specific queries your ideal customer types.
Step 5: Evaluate Keyword Difficulty
Not all keywords are worth going after, even with good search volume. You also need to assess how hard it will be to rank.
When reviewing a keyword, look at the top 10 results on Google:
– Are the results dominated by large, authoritative brands?
– Are any of the ranking pages from smaller or newer sites?
– Is the content quality on those pages actually high?
If smaller sites are already ranking, that’s a green light. If every result is from a major publication or well-established brand, move on and find a more specific angle.
Step 6: Map Keywords to Content
Once you have a list of viable keywords, assign each one to a specific page or blog post. The goal is one primary keyword per page, supported by related secondary keywords throughout the content.
Keep a simple tracking spreadsheet with columns for:
– Keyword
– Monthly search volume
– Difficulty estimate
– Assigned page or post
– Status (planned / in progress / published)
This keeps your content strategy organized and ensures you’re not accidentally targeting the same keyword with multiple pages (a problem called keyword cannibalization).
How Often Should You Do Keyword Research?
For most small businesses, a keyword audit every three to six months is sufficient. However, you should be continuously adding new keywords as you publish new content and as your business evolves.
