How to Do Keyword Research for Free
Keyword research is the process of finding the words and phrases people type into search engines, so you can create pages that match what they want. Many beginners believe it requires an expensive subscription. It does not. With a few free sources and a little patience, you can build a solid keyword list for any topic. This guide walks you through a practical method step by step.
What is a keyword, really?
A keyword is any word or phrase someone searches for. "Shoes" is a keyword, but so is "best running shoes for flat feet". The longer, more specific phrases are called long-tail keywords. They get fewer searches each, but the people searching are usually clearer about what they want, and there is less competition. For a new website, long-tail keywords are the best place to start.
Step 1: Brainstorm seed topics
Write down five to ten broad topics related to your site. If you run a cooking blog, they might be "meal prep", "vegetarian dinners" or "air fryer recipes". Think about the questions a beginner would ask and the problems you can solve. These seed topics are the starting points for everything else.
Step 2: Use Google's own suggestions
Google shows you what people really search for, and it is completely free.
- Autocomplete. Type a seed topic into the search box and note the suggestions that appear. Add a letter after your topic, such as "meal prep a", to see more.
- People also ask. This box lists related questions. Each one is a possible article or section heading.
- Related searches. At the bottom of the results page, Google lists similar queries worth noting.
Step 3: Check Google Search Console
If your site already has some pages, Google Search Console is the most valuable free source. Its performance report shows the queries that already bring impressions and clicks. Look for queries where you appear on page two or three. Improving those existing pages is often faster than writing a new one.
Step 4: Use Google Trends and Keyword Planner
Google Trends shows whether interest in a topic is rising, falling or seasonal, and lets you compare two phrases side by side. Google Keyword Planner is free with a Google Ads account and gives search volume ranges and related ideas. You do not need to run any ads to use it. Treat the numbers as rough guides rather than exact figures.
Step 5: Understand search intent
For each keyword, search for it and look at the top results. Are they guides, product pages, videos or lists? This tells you the intent behind the search. Choose keywords where you can realistically create the type of page that Google already shows. If every result is a big brand store and you are writing a blog post, pick a different keyword.
Step 6: Judge the competition
You do not need a paid difficulty score. Look at the first page and ask a few simple questions. Are the results from huge, well-known websites, or do small sites appear too? Are the pages thorough, or thin and outdated? If you can see weak or old pages ranking, that is an opportunity. If every page is excellent and recent, you may want a more specific angle.
Step 7: Organize your list in a spreadsheet
Create a simple sheet with these columns: keyword, intent, rough popularity, competition notes, and the page you plan to write. Group similar keywords together. Many variations of the same question can be answered by a single page, so avoid creating several pages for nearly identical searches.
Step 8: Put keywords to work
Place your main keyword naturally in the page title, the main heading, the opening paragraph and the URL. Use related phrases in subheadings and the body. Our Meta Tag Generator helps you write a title and description, and the Keyword Density Checker shows which words your draft uses most so you can spot gaps or overuse.
Common mistakes to avoid
- Chasing only high-volume keywords that you cannot realistically rank for.
- Ignoring intent and writing the wrong type of page.
- Repeating the same keyword unnaturally.
- Never revisiting old research. Interests and search habits change, so refresh your list every few months.
Conclusion
Free keyword research is about listening to your audience. Start with seed topics, collect real phrases from Google and Search Console, check intent and competition, and organize everything in a simple sheet. Then write helpful pages built around the questions people are actually asking. With consistent practice, you will find opportunities that bigger sites overlook.
