Short answer: yes, Google Keyword Planner is free. You need a Google Ads account to open it, but you don’t have to run a single ad or spend a penny to use it.
That makes it one of the best free keyword tools going, because the data comes straight from Google itself. No third party estimating volumes — this is the source. But there’s a catch almost nobody mentions up front, and it changes how useful the tool actually is. Let’s get you in, then I’ll be straight about the limitation.
How to use Keyword Planner without running ads
The bit that trips people up is the sign-up. Google really wants you to create a live ad campaign, and the flow nudges you towards it hard. You don’t have to.
Create a Google Ads account with your normal Google login. When it pushes you to set up a campaign, look for the option to switch to “Expert Mode” or to create an account without a campaign — the wording moves around, but there’s always a way to skip past the campaign setup. Once you’re in, you’ll find Keyword Planner under the Tools menu. No ad, no spend, full access to the planner.
From there you can do two things: discover new keywords (type a word or your website and get related ideas) and get search volumes for a list of keywords you already have.
The catch: you get ranges, not real numbers
Here’s the part the “it’s completely free!” guides skip.
If you’re not spending money on ads, Google shows you search volume as broad ranges rather than exact figures. Instead of “2,400 searches a month,” you’ll see “1K–10K”. That’s a huge band. A keyword getting 1,100 searches and one getting 9,500 look identical.
For a rough sanity-check — is this a busy topic or a dead one? — that’s fine. For deciding which of two similar keywords is worth your time, it’s frustratingly vague. The exact numbers only unlock once you’ve got an active ad budget running, which rather defeats the point if you’re here to avoid spending.
The bigger gap: it says nothing about difficulty
Even setting the ranges aside, Keyword Planner has the same blind spot every free tool has. It’ll happily tell you a keyword gets plenty of searches. It won’t tell you whether you can rank for it.
You could find a keyword with 10,000 monthly searches and have no idea whether page one is wide open or locked up by sites you’ll never outrank. Volume without difficulty is half the picture — arguably the less important half, because a keyword you can’t rank for is worth nothing no matter how many people search it.
Where Keyword Planner fits, honestly
Use it for what it’s genuinely good at: generating keyword ideas at scale and getting a rough read on whether a topic has any search demand at all. Paired with the other free options in my free keyword research tools roundup, it’s a solid, no-cost starting point.
When you want the two things it can’t give you — exact volumes and a difficulty score — that’s when a cheap paid tool earns its place. I use Mangools’ KWFinder: precise search volumes, plus a difficulty score from 0 to 100 that tells you at a glance whether a keyword’s worth chasing. It’s a fraction of the price of Ahrefs or Semrush, and there’s a 10-day free trial with no card required if you want to see the difference on your own keywords first.
Keyword Planner gets you the ideas for free. A difficulty score tells you which of them to actually write. Between those two, you’ve got proper keyword research without a big monthly bill.
Frequently asked questions
Is Google Keyword Planner really free?
Yes. You need a Google Ads account to access it, but you don’t have to run ads or spend anything. The tool itself costs nothing.
Why does Keyword Planner show ranges instead of exact search volumes?
Because you don’t have an active ad spend. Without a live campaign, Google displays volume as broad bands like “1K–10K”. Exact figures only appear once you’re spending on ads.
Does Google Keyword Planner show keyword difficulty?
No. It shows search volume and competition for advertisers (how many people bid on the keyword), which is not the same as how hard it is to rank organically. For that you need a dedicated keyword difficulty score.
