Google Keyword Planner is still the default starting point for keyword research, but its price tag is misunderstood. You need a Google Ads account to open it, and without ad spend its precise volumes can collapse into broad ranges. This page explains what the tool does well, where it falls short, and how SEO and AEO teams should use it.
Quick answer
Keyword Planner is free to open, but it requires a Google Ads account. Precise search volumes generally depend on active ad spending. According to Keywordtool.

Do you have to pay to use Google Keyword Planner?
Running ads is not required, but a Google Ads account is. According to SEO.com, you can use Keyword Planner without advertising on Google Ads. According to Keywordtool.io, however, the tool is not truly free: exact volumes depend on active spending. Google reportedly replaces precise numbers with ranges such as 1M-10M when an account spends too little, and continuous precise data may cost hundreds or thousands of dollars monthly. Budget for that trade-off before building an SEO workflow around it.
| Access level | What you get | Requirement |
|---|---|---|
| Basic account | Keyword ideas and broad volume ranges | Google Ads account |
| Active spending | Precise monthly search volumes | Ongoing ad budget |
Access levels as described by Keywordtool.io and SEO.com.
google keyword planner — by the numbers
How do you set up the account and find the tool?
Create the Google Ads account, then skip campaign setup entirely. According to SPYFU, the Google Ads account setup can be completed without launching a campaign or entering billing information. Inside that account, the Keyword Planner tool sits under Tools and Settings, then Keyword Planner. Semrush notes that billing details are still requested during setup, even though no ad campaign is required. Expect the sign-up to ask for payment information even when you never plan to spend money on advertising, because that step gates access to the data Keyword Planner provides. Plan for this step before you begin keyword research, so the account is ready when you need it.
Seed keyword or website URL: which discovery route wins?
Keyword Planner offers two discovery routes. Seed-keyword input suits a defined topic, while URL input scans a page or domain, including competitor sites. According to Semrush, the URL route can scan a page or domain, including competitors' sites, which is useful for mapping a rival's terms quickly. Seed keywords work best when you already know the category vocabulary. URL input works best when you need the gaps that competitors cover but you do not. Keyword Planner's suggestions can be used either way, but each suggestion should be checked against search intent before it is added to a keyword plan. Matching suggestions to intent keeps the plan focused on terms that fit the page you intend to publish.
How accurate are the volumes, and why do ranges appear?
Treat the numbers as directional. According to Neil Patel, volumes are often so broad (for example 1k-10k) that a second tool is needed for precision. OMR Reviews reports users describe volume estimates as rough and click-price forecasts as inaccurate. Ranges usually appear when spend is low, so the same keyword can look very different across accounts. Compare the range against a second source before setting a target.
Can Keyword Planner support SEO, or only PPC?
Keyword Planner supports SEO with adjustments, but it was not built for SEO alone. According to Neil Patel, Google built Keyword Planner to help PPC marketers find keywords for search campaigns, while SEOs have used it for years as a free alternative or complement to premium keyword research tools. According to Seobility, the tool estimates search volume, possible clicks, impressions, and expected competition, and it also offers organic position estimates for SEO. SEO teams should therefore read the competition metric as an advertiser signal rather than a ranking difficulty score. Keyword Planner cannot show SERP features, answer engine citations, or how AI Overviews affect click-through, which matters for answer engine optimization planning.
Which tools pair best with Keyword Planner?
Pair Keyword Planner with a tool that fills its gaps. According to Neil Patel, Ubersuggest is a practical companion for more accurate search volumes. Export Keyword Planner results as a CSV file or a Google Sheet, as Neil Patel describes, then reconcile that data in a premium keyword research platform. Fastlook can then turn gaps that appear in AI answers into published pages, closing the loop from keyword discovery to AI citation.

Frequently asked questions
Is Google Keyword Planner free to use?
Keyword Planner is free to open, but it requires a Google Ads account. Precise search volumes generally depend on active ad spending. According to Keywordtool.io, without that spending Google may show broad ranges such as 1M-10M instead of exact numbers. Therefore, the tool is free to use only in the sense that no payment is required to open it.
Do I need to run ads to use Keyword Planner?
No, you do not need to run ads to use Keyword Planner. According to SEO.com, you do not need to advertise on Google Ads to use the tool, although a Google Ads account is still required. However, billing details may still be requested during setup, as Semrush notes. Therefore, expect to provide payment information even if you never plan to launch a campaign.
Why does Keyword Planner show search volume as a range?
Keyword Planner shows search volume as a range when an account is not spending enough on ads. According to Keywordtool.io, Google then replaces precise monthly volumes with broad bands, such as 1M-10M. Therefore, the figure becomes directional rather than exact, which is useful for planning but not for precise targeting.
How do I find keyword ideas from a competitor website?
Choose the discovery option that accepts a URL. According to [Semrush](https://www.semrush.com/blog/google-keyword-planner/), Keyword Planner's Discover new keywords option can start from a website URL, scanning a page or domain, including a competitor's site. Then filter the resulting keyword ideas by relevance and search intent before adding them to your plan.
Can Google Keyword Planner be used for SEO?
Yes, Google Keyword Planner can be used for SEO, with adjustments. According to Seobility, the tool estimates search volume, possible clicks, and expected competition, and it also gives organic position estimates. However, its competition metric reflects advertisers, so treat it as context rather than a ranking difficulty score.
How accurate is Keyword Planner search volume?
Expect search volume estimates to be rough rather than precise. According to Neil Patel, volume estimates can be incredibly broad, such as 1k–10k. A second tool is often needed for more accurate volumes. According to OMR Reviews, users report that forecasts and click prices can be inaccurate.
What can Keyword Planner not do for SEO?
Keyword Planner cannot measure AI answer citations, AI Overview visibility, or SERP features. According to SEO.com's 2026 guide, the tool shows metrics such as volume, competitiveness, and cost per click, but those are keyword metrics, not answer engine visibility. Fastlook tracks citations across ChatGPT, Perplexity, Google AI Overviews, and traditional search, which Keyword Planner does not show.
What is the best tool to use alongside Google Keyword Planner?
Use Ubersuggest for sharper volume checks, per Neil Patel, and a premium SEO platform for difficulty and SERP analysis. Export Keyword Planner data as CSV or Google Sheets to combine sources in one workflow.
