Top Free Keyword Research Tools in 2024: Find Hidden Gems Without Spending a Dime
You know the drill. You’ve got a blog post or a product page to optimize, and the first thing everyone tells you is “do keyword research.” But when you look up keyword research tools, the big names like Ahrefs or Semrush cost a small fortune each month.
Good news: 2024 is stacked with solid free keyword research tools that actually work. You don’t need to drop $100+ to find terms that drive traffic. I’ve tested a dozen free options this year, and these are the ones that deliver real results.
Why Free Tools Still Matter for SEO
Most people assume free means useless. That’s wrong. Free tools have limitations—lower data caps, fewer filters, sometimes less accuracy. But they’re perfect for:
- Validating ideas before you commit budget
- Quick research for small sites or side projects
- Learning the ropes if you’re new to SEO
- Finding long-tail keywords that big tools overlook
The trick is knowing which tools to use and how to combine them. Let’s dive into the best free keyword research tools available in 2024.
1. Google Keyword Planner (Still the King)
You probably already have a Google Ads account. If not, create one (it’s free). Keyword Planner remains the most reliable free keyword research tool for search volume data.
What it does well: - Gives you monthly search volume ranges (not exact numbers, but close enough) - Shows competition level (low, medium, high) - Suggests related keywords based on your seed term - Lets you filter by location and language
Pro tip: Don’t just look at the suggested keywords. Enter a competitor’s URL or a landing page you admire. The tool will show you what keywords that page ranks for. That’s pure gold.
Limitation: You need an active Google Ads campaign to see exact search volumes. Without it, you get ranges like “1K–10K” which is vague but still usable.
2. Ubersuggest (Neil Patel’s Free Tier)
Ubersuggest has been around for years, and its free plan in 2024 is surprisingly generous. You get 150 free searches per day (up from 100 last year). That’s enough for most small projects.
Standout features: - Content ideas tab shows top-performing pages for any keyword - Keyword difficulty score (0–100) helps you spot low-competition terms - SERP analysis shows who ranks and their backlink profile - Filter by country (supports 30+ countries)
How I use it: I start with a broad term like “best hiking boots.” Ubersuggest shows me related long-tail keywords like “best hiking boots for wide feet” or “waterproof hiking boots under $100.” Then I check the difficulty score—anything under 40 is a green light.
Limitation: Data accuracy drops for low-volume keywords (under 100 searches/month). Cross-check with Google Keyword Planner for those.
3. AnswerThePublic (Visual Keyword Discovery)
This tool is a goldmine for content creators. Type in a seed keyword, and it generates questions, prepositions, comparisons, and alphabetical lists based on autocomplete data from Google and Bing.
Why it’s unique: - Visual wheel format makes idea generation fast - Question-based keywords (what, why, how, when) are perfect for blog posts - Free tier gives you 3 searches per day (enough for regular use) - Export to CSV for easy organization
Example: Search “keto diet.” AnswerThePublic shows questions like “Is keto diet safe for women over 50?” or “How to start keto diet without keto flu.” Those are exact search queries people type into Google—and they’re low competition.
Limitation: The free version shows results in a single format (wheel). The paid version unlocks more views. But the wheel is fine for most needs.
4. Keyword Sheeter (The Data Dump)
If you want raw volume—thousands of keyword ideas in one shot—Keyword Sheeter is your tool. It scrapes Google Autocomplete and other sources to generate massive lists.
What sets it apart: - No daily limit on the free plan (unusual for free tools) - Export to CSV with search volume estimates (from Google Ads API) - Filter by word count (find 3-word, 4-word long-tail terms easily) - Competitor analysis (enter a URL and get their keywords)
Pro tip: Use the “Negative Keywords” filter to exclude terms you don’t want. For example, if you sell premium products, exclude “cheap” or “free.” This cleans up your list fast.
Limitation: The UI is cluttered with ads. Also, the search volume estimates are rough—treat them as directional, not exact.
5. Soovle (Multi-Engine Autocomplete)
Soovle is a lightweight tool that shows autocomplete suggestions from Google, Bing, YouTube, Amazon, and Wikipedia all at once. It’s not for volume data, but it’s fantastic for brainstorming.
Best use cases: - E-commerce keywords (Amazon suggestions show what people actually buy) - Video content ideas (YouTube suggestions are gold for video SEO) - Local SEO (Google suggestions with “near me” or city names)
How to use it: Type “best budget laptop” and watch suggestions pop from every platform. Amazon might show “best budget laptop for college,” while YouTube shows “best budget laptop 2024 review.” Combine those into a single content piece.
Limitation: No search volume or difficulty data. Use it as a starting point, then validate with another tool.
6. Google Trends (Seasonal & Trending Keywords)
Google Trends isn’t a traditional keyword tool, but it’s essential for timing your content. It shows you if a keyword is rising, falling, or seasonal.
Key features: - Compare up to 5 keywords to see which has more interest - Filter by region (country, city, or metro area) - Related queries and topics (often reveal hidden long-tail terms) - Real-time data for breaking trends
Example: In early 2024, “AI writing tools” spiked. But “AI content detector” also rose. That second term was a great opportunity for comparison posts.
Limitation: No search volume numbers. Use it alongside other tools for context.
7. Keyword Surfer (Browser Extension)
This Chrome extension integrates directly into Google search results. When you search a term, it shows search volume, keyword ideas, and related terms in the sidebar.
Why it’s a must-have: - Instant volume data without leaving Google - Related keywords appear based on your actual search - Content length suggestions (shows average word count for top-ranking pages) - Free and lightweight (no signup required)
Pro tip: Use it to audit your own rankings. Search your target keyword, and the extension shows you where your site ranks (if indexed). That’s a quick sanity check.
Limitation: Data is limited to Google’s top 10 results. Not good for deep analysis.
8. LowFruits (Free Tier for Long-Tail Keywords)
LowFruits specializes in finding “low-hanging fruit” keywords—terms with low competition but decent search volume. The free tier gives you 25 keywords per project.
What it does: - Scans the first 100 Google results for each seed keyword - Ranks keywords by “fruit score” (combination of volume and competition) - Filters for “easy” keywords (pages with few backlinks and low authority) - Shows page title and URL of current ranking pages
Example: I used it for a site about “indoor plants.” It found “low light indoor plants bathroom” with 800 monthly searches and a fruit score of 85 (very easy). I wrote a quick post and ranked in 3 weeks.
Limitation: The free tier is limited to 25 keywords per project. Upgrade for more.
9. Google Search Console (Your Own Data)
You already own this tool if you have a Google Search Console account. It shows you exactly what keywords your site ranks for, plus click-through rates and impressions.
How to use it for keyword research: - Go to Performance > Search Results - Filter by Average Position (look for keywords ranking at positions 10–20—those are easy wins) - Sort by Impressions (high impressions + low clicks = opportunity to improve) - Export the data and find patterns
Pro tip: Look for keywords where your click-through rate is below 2%. That means your title or meta description isn’t compelling. Rewrite it and watch traffic grow without adding new content.
Limitation: Only shows keywords you already rank for. Not useful for brand-new topics.
10. Keyworddit (Reddit Keyword Discovery)
Reddit is a treasure trove of real user questions. Keyworddit extracts keywords from subreddits related to your niche.
Why it works: - Real human queries (not algorithmic suggestions) - Niche-specific (find subreddits r/woodworking, r/digitalnomad, etc.) - Free and simple (enter a subreddit, get a keyword list)
Example: For a site about “fishing gear,” I searched r/fishing. Keyworddit returned terms like “best fishing rod for beginners saltwater” and “how to tie a palomar knot.” Those are exact search queries people use.
Limitation: No volume data. Use it for ideas, then validate.
How to Combine Free Tools for Maximum Results
One tool alone isn’t enough. Here’s a workflow I use:
- Brainstorm with AnswerThePublic or Soovle for 5–10 seed ideas
- Validate with Google Keyword Planner for search volume
- Check competition with Ubersuggest (difficulty score under 40)
- Find long-tail variations with Keyword Sheeter (filter for 3–5 word terms)
- Verify seasonality with Google Trends
- Audit your current rankings with Google Search Console
Common Mistakes to Avoid
- Ignoring search intent. A keyword with high volume but wrong intent (e.g., “buy running shoes” when you write a review) won’t convert.
- Over-relying on one tool. Free tools have gaps. Cross-check with at least two.
- Forgetting mobile. 60%+ of searches happen on mobile. Use Google Trends to filter by device.
- Chasing high-volume terms. A term with 100 searches and low competition beats one with 10,000 and high competition.
Final Thoughts
The best free keyword research tools in 2024 aren’t about replacing paid software—they’re about being smarter with what’s available. You don’t need a $200/month subscription to find profitable keywords. Combine Google Keyword Planner, Ubersuggest, AnswerThePublic, and Google Search Console, and you’ve got a solid setup.
Start small. Pick one tool from this list, run a search for your niche, and write down 10 keyword ideas. Then validate them. That’s how you build a keyword library without spending a cent.
