When done right, the best từ khóa research tools simplify and streamline your workflow—they make it easier lớn find the right từ khoá to target & give you the data you need khổng lồ actually rank for them. But they shouldn't require you khổng lồ empty out your bank account and sell your first-born child in order khổng lồ access that data.
After years of working with multiple clients who use all different tools for keywords research & SEO nội dung optimization, I've seen the best (and the worst) of them—and I know how important it is to lớn choose the right keyword planner tool. Khổng lồ help, I considered over 70 tools with a free option for keyword research. After in-depth testing, here are the four best không lấy phí keyword research tools, including the all-around greats và apps built for more specific use cases.
The best không tính phí keyword research tools
What makes the best keywords research tool?
How we evaluate & test apps
Our best apps roundups are written by humans who've spent much of their careers using, testing, và writing about software. Unless explicitly stated, we spend dozens of hours researching & testing apps, using each app as it's intended to lớn be used và evaluating it against the criteria we set for the category. We're never paid for placement in our articles from any phầm mềm or for liên kết to any site—we value the trust readers put in us to offer authentic evaluations of the categories và apps we review. For more details on our process, read the full rundown of how we select apps to feature on the Zapier blog.
The features that make for a great từ khoá research tool are pretty straightforward: you tìm kiếm for a given keyword, và the tool tells you about it. But there are so many different ways khổng lồ use từ khóa data, so I wanted khổng lồ find tools that could handle a variety of use cases, along with a few designed for some of the most popular uses for keyword research.
During testing, I looked primarily at the factors below lớn determine which apps made our initial list.
Data sources. You should be able lớn trust that your keywords data is không tính tiền of errors & biases, so considering where the data in each từ khoá research tool comes from was an important step for us. Every tool we included pulls data in from google analytics or Google tìm kiếm Console at a minimum.
Keyword optimization guidance. You shouldn't have khổng lồ be a 10-year SEO industry veteran lớn use keywords research tools—the best tools offer simple, straightforward suggestions to optimize for your keywords. There are tools (like Ahrefs, Semrush, & Moz) that vì complete SEO analysis on your site, checking for everything from site speed and technical details to domain name authority và topic clusters. That's not what we're looking for here. We're looking for tools that any business owner or marketer can use to lớn quickly understand their target keyword & optimize their site to lớn rank for it.
Free plan allowances and upgrades. Some tools include super limited results for không tính phí and gọi it a "free plan." Or they put time limits on the miễn phí plan, effectively making it more of a trial. I only included tools with evergreen không tính tiền plans generous enough to lớn actually be useful—and they won't break the bank when it's time to upgrade, either.
Standalone functionality. Since you're looking for something free, your từ khoá tool should be a one-stop shop—without requiring any additional tools or extensions to work for you, especially not ones you'd have to lớn pay for.
To find the best of the best, I put each tool that checked those boxes lớn the chạy thử by running through an in-depth protocol. Here's what my testing workflow looked like:
If needed, I created an account và went through any provided onboarding or guided tutorials (many of these không tính tiền apps don't require tài khoản creation or provide any onboarding).
I checked which related keywords, metrics, and other data were offered. I also made cảnh báo of the source, whether information was pulled from Google, included non-search engine websites (like social truyền thông media or forums), or was drawn from the tool's own native data.
I verified allowances for the không tính tiền plan—whether limited by time, number of results, metrics included, searches per day or month, or something else—and the cost lớn upgrade khổng lồ a paid plan if needed.
Where available, I tested out additional keywords research tools like competitive gap analysis, nội dung optimization features, & more.
After spending over a dozen hours with these apps this year, I landed on the four best từ khóa research tools—each with a manageable không lấy phí version—below.
The best free keyword research tools at a glance
Moz từ khóa Explorer | An all-around solution | "Priority" score for determining valuable keywords | 10 queries per tool per month, with 1,000 keyword suggestions và 10 SERP analyses per query |
Google từ khóa Planner | Researching paid keywords | Forecasting features and budget planning | Completely không tính phí (but you get more out of it if you use Google Ads) |
Ahrefs không tính tiền SEO Tools | Breadth | Includes từ khoá research for You | Free keyword Generator with up lớn 150 từ khoá suggestions; keyword Difficulty Checker with difficulty score and SERP analysis for the top 10 results |
Semrush | Advanced SEO professionals | Granular keywords data | 10 Analytics reports per day, 10 tracked keywords |
Moz pros:
More approachable data presentation than many other tools
"Priority" score makes it easy khổng lồ find the keywords worth chasing
Broad mix of tools available for free
Moz cons:
Less data than more robust tools
Free plan only includes 10 queries per tool per month
Moz's SEO platform offers several different tools designed for từ khoá research. While Moz doesn't include as many data points as some of the other full-featured SEO tools (like SERP position history or the total number of keyword a competing result ranks for), I'd consider that a benefit. It makes for a less overwhelming user experience for those who aren't professional search marketers, without skimping on the metrics you really want.
With the keywords Explorer tool, you can tìm kiếm any từ khóa you choose and see its monthly volume, difficulty, & organic clickthrough rate (CTR). Scroll down from there khổng lồ see an analysis of current results ranking for it and suggestions for similar keywords.
My favorite feature: Moz includes a "Priority" score that simplifies keyword research by giving you the bottom line on whether a keyword is worth chasing for you. Moz automatically calculates the score based on the keyword's volume, organic CTR, & difficulty, along with your "My Score"—a metric you set yourself, designating how important a given từ khoá is to lớn your business, based on your own expertise và knowledge of your business and industry.
Plus, with the keywords Gap feature (part of the Competitive Research tool), you can find all the từ khoá your competitors rank for that you don't.
Moz pricing: keywords research features are available for không lấy phí for up to lớn 10 queries per tool per month with up to lớn 1,000 từ khóa suggestions and 10 SERP analyses per query; Moz Pro plans start at $99/month for 150 từ khóa queries per month
Google từ khóa Planner pros:
Completely không tính tiền forever, even if you don't use Google Ads
Helpful forecasting features for budgeting if you do use Google Ads
Can pull keyword suggestions from just your website
Google từ khoá Planner cons:
Not helpful for organic keywords research
When it comes to PPC từ khoá research, Google từ khoá Planner is one of the best tools out there. It's completely miễn phí (even if you don't buy Google Ads), so you never have to lớn worry about running into limits or expensive upgrades.
Google keywords Planner includes two main features: one for exploratory keyword research & discovery & another for more in-depth research on search volume and forecasting.
The "Keyword ideas" feature is similar to lớn many of the tools on this list: you search for a seed term, and it generates other từ khóa ideas, along with details on monthly search volume, change over time, competition, ad impression share, and bid ranges. You can refine your keyword menu by brand or non-brand keywords, source website, & more. If you're also using Google Ads, the "Forecast" feature makes it easier to lớn plan ahead for your paid ads & budget in advance.
Keyword Planner can inform your organic strategy, too, by showing you where ranking organically may help you save on PPC costs.
Google keyword Planner pricing: Free
Ahrefs pros:
Free tools cover a broad array of SEO use cases
Super simple lớn use
Includes keyword research for non-search engines (You
Tube, Amazon, Bing)
Ahrefs cons:
Limited amount of data available for free
While you can't access the full Ahrefs suite for free, the company offers a surprisingly robust phối of miễn phí SEO tools that are perfect for doing simple từ khoá research. The free suite includes a free Keyword Generator, keyword Difficulty Checker, keyword Rank Checker, and keyword research for You
Tube, Amazon, and Bing, among other tools.
The keyword generator includes up khổng lồ 150 keywords ideas for miễn phí (100 phrase match keywords and 50 question-based keywords), along with data on monthly tìm kiếm volume for each và keyword difficulty for the vị trí cao nhất 10 results. The từ khoá difficulty tool includes a difficulty score, estimated number of liên kết needed to lớn rank, and SERP analysis for the top 10 results.
None of these tools will give you the depth of data you'd get from a paid account, but the suite's breadth is a strength. Taken together, Ahrefs free tools can handle just about anything a basic SEO operation needs—keyword research, yes, but also liên kết building, trang web audits, ranking và traffic monitoring, and more. And if your budget changes, you can upgrade khổng lồ a tool that rivals the best of the best.
Ahrefs pricing: không tính tiền Keyword Generator includes up khổng lồ 150 từ khoá suggestions with limited data, and Keyword Difficulty Checker includes difficulty score, link estimate, and basic SERP overview; paid plans start at $99/month for 500 tìm kiếm credits per month, additional data, & up to 5 từ khóa lists.
Semrush pros:
Tons of granular keywords data
Wide range of specialized keyword research tools
Pretty generous không tính phí plan
Semrush cons:
Can be overwhelming for those less experienced with keyword research
Most expensive upgrade
If you're looking for something more advanced, Semrush shares a ton of từ khoá data and makes it easy to dig into the details, like SERP features (featured snippet, reviews, site links, image pack, and so on) and granular analysis of current results. Semrush offers a broad range of từ khoá research tools, too, from the standard traffic and tìm kiếm volume data to content-driven từ khoá research và competitive từ khoá gap analysis.

That range is what really sets Semrush apart, including the standard keywords Overview, the keywords Magic Tool for exploratory từ khóa research, a từ khóa Manager và position tracking, competitive keyword Gap analysis, và Organic Traffic Insights, which—when connected with your web analytics or search Console account—can uncover those famously tricky "not provided" keywords.
As an added bonus, the SEO nội dung Template tool lets you automatically create a content brief and optimize content as you write by grading your nội dung in real-time for readability, originality, tone of voice, & SEO: it uses a handy bullseye graphic lớn help you strike the right balance. Plus, the tool visually checks off SEO recommendations (like using your target and related keywords & adding relevant links and images) as you go.
All of this means that upgrading will cost you a pretty penny—but you can use it for không lấy phí at low volumes lớn start.
You can bởi more with Semrush by connecting with Zapier to keep track of SEO tasks across Semrush & your project management tool, automate site audits and re-crawls, connect with google analytics goals, & more. Here are some examples:
