Best Free Keyword Research Tools in 2024 (That Actually Work)
You don’t need to drop $99 a month on Ahrefs or SEMrush just to find decent keywords. Honestly, most beginners waste money way too early. I’ve been doing SEO for over a decade, and I still lean on free tools for half my keyword discovery.
The catch? Most “free” lists online are outdated or push freemium garbage that locks every useful feature behind a paywall. So I tested 15+ tools this month. Here are the ones that genuinely hold up in 2024, plus exactly how to use them like a pro.
Why Free Keyword Tools Are Enough (For Most People)
Let’s be real. If you’re running a local business, a niche blog, or an affiliate site, you don’t need enterprise-level data. You need:
- Search volume trends (even rough ones)
- Keyword difficulty hints
- Long-tail keyword ideas
- Questions people actually ask
Free tools nail all four. The only thing you lose is massive backlink databases and advanced SERP analysis. And guess what? You can work around that too.
The 7 Best Free Keyword Research Tools in 2024
1. Google Keyword Planner (Still King for Volume)
Yeah, it’s built for ads, but you can use it for free SEO research. The trick? Don’t look at the suggested bid. Look at the volume ranges and competition level.
How to use it properly: - Sign in with a Google Ads account (you don’t need to run ads) - Click “Discover new keywords” - Enter a seed keyword like “best running shoes” - Filter by “Long-tail” and set the competition to “Low”
The ranges (e.g., 1K–10K) are annoying, but they’re reliable for spotting trends. If a keyword jumps from 100–1K to 1K–10K in a month, that’s your signal.
Pro tip: Use the “Get volume and forecasts” tab and add your website. Then Google shows you which keywords you already rank for but could improve. That’s a goldmine you’re missing.
2. Ubersuggest (Generous Free Tier)
Neil Patel’s tool gives you 3 free searches per day, and that’s enough if you’re focused. Unlike some others, the free version shows actual search volumes, not ranges.
What I like: The “Keyword Ideas” tab clusters long-tail variations by topic. For example, searching “meal prep” gives you “meal prep for weight loss,” “meal prep containers,” and “meal prep on a budget.” That saves you 30 minutes of brainstorming.
Limit: You can’t export data on the free plan. So screenshot or copy-paste into a Google Sheet.
3. AnswerThePublic (Visual Question Goldmine)
This tool scrapes Google autocomplete and visualizes questions, prepositions, and comparisons. It’s not a volume tool—it’s a content idea tool.
- Type in “keto diet”
- You’ll see “keto diet for beginners,” “keto diet vs paleo,” “keto diet what can you eat”
Each one maps to a long-tail keyword with low competition. Perfect for blog posts, FAQs, or YouTube video scripts.
Update in 2024: The free version now limits you to 3 searches per day (used to be unlimited). Still worth it because the data is unique.
4. Google Search Console (Your Own Data, Free Forever)
This isn’t a traditional keyword tool, but it’s the most accurate one you’ll ever use. GSC shows you real queries people used to find your site—not estimates.
The 2024 trick: Go to Performance → Queries. Filter by position 5–15. Those are keywords you’re almost ranking for. Write better content or add internal links to push them to page one.
No other free tool gives you this level of intent data. Combine it with Keyword Planner for volume, and you’ve got a complete picture.
5. Keyword Surfer (Chrome Extension, Zero Limits)
I’m surprised more people don’t use this. It’s a free extension that overlays search volume, CPC, and related keywords directly on Google SERPs.
Why it’s better than most: No signup, no daily limits, no paywall. You just search Google and see the data appear next to each result.
It also shows you content briefs—like word count and headings of the top-ranking pages. That’s insane value for a free tool.
One flaw: The volume data is estimated and sometimes off by 20%. But for quick checks, it’s unbeatable.
6. Soovle (The Ultimate Brainstormer)
Soovle aggregates autocomplete from Google, YouTube, Amazon, Bing, and Wikipedia—all in one screen. It’s not for volume data, but it’s perfect for finding niche angles.
Example: You’re writing about “home workouts.” Soovle shows you what people type on Amazon (like “home workout equipment”) vs. YouTube (like “home workout for women over 50”). That’s different intent, and you can target each separately.
Free forever, no login. Just don’t expect pretty UI.
7. Google Trends (For Seasonal Spikes)
Ride the wave, don’t chase it. Google Trends shows you seasonality and rising interest for any term.
- Compare “Christmas gifts” vs. “summer gifts” to plan content calendars
- Use the “Breakdown by subregion” to find local keywords
2024 update: Google Trends now includes a “Related queries” section that updates in real-time. Check it weekly for emerging terms before they get competitive.
How to Combine These Tools Into a Killer Workflow
Don’t use just one. Here’s my 20-minute routine:
- Start with Keyword Surfer (1 min) – Scan your seed keyword’s SERP for volume and difficulty
- Open AnswerThePublic (3 min) – Grab 10 questions for long-tail angles
- Punch those into Google Keyword Planner (5 min) – Check actual volume ranges and filter by low competition
- Cross-reference with Google Trends (2 min) – Ensure the topic isn’t dying out
- Check your GSC queries (5 min) – Find your own near-miss keywords to target
That gives you 20–30 solid keywords, all backed by data, all free.
Common Mistakes to Avoid (Even With Free Tools)
Mistake #1: Obsessing over exact search volume. Estimates vary wildly. Focus on trend direction instead.
Mistake #2: Ignoring keyword difficulty. A keyword with 50K searches but 90% difficulty is useless for a new site. Use the free difficulty scores in Ubersuggest or Keyword Surfer.
Mistake #3: Only targeting head terms. “SEO tools” is impossible. “SEO tools for small business owners” is winnable. Always go long-tail first.
Mistake #4: Not checking the SERP. If the top 10 results are all Reddit and Quora, that’s a sign the search intent is informational, not transactional. Don’t try to sell there.
When You Should Finally Upgrade to Paid Tools
Free tools work until they don’t. Upgrade when:
- You’re doing client SEO (need white-label reports)
- You’re targeting highly competitive niches (like finance or health)
- You need historical data (free tools only show current snapshots)
But until then, the seven tools above will cover 90% of your needs. Save the $99/month for content or outreach instead.
Final Thought (No Fluff)
Keyword research isn’t about finding the “perfect” tool. It’s about finding the right keyword with the tools you have. The ones above are battle-tested, updated for 2024, and completely free.
