Glimpse vs Google Keyword Planner in 2026: A free Google Trends overlay vs the only free source of Google search volume
Both tools are free to start. One fixes Google Trends' relative index and forecasts where a topic is heading. The other gives you real search volume and CPC from Google Ads, but only shows precise numbers once you are spending on ads.
Google Keyword Planner is completely free with no paid tier at all; Glimpse's free plan only unlocks limited absolute search volume data, and Pro and Enterprise pricing are both hidden behind a signup or sales call.
Google Keyword Planner's search volumes are shown as broad ranges unless the connected account has active Google Ads spend; Glimpse's free extension shows limited real numbers directly in Google Trends, with full absolute search volume unlocked on the Pro plan.
Glimpse forecasts a 12-month trend trajectory with a claimed 95%+ backtested accuracy; Google Keyword Planner's forecasting tool only projects clicks, impressions, and cost for a paid campaign at a given bid, not organic trend direction.
Google Keyword Planner's data is accessible via the Google Ads API using a developer token; Glimpse restricts API access to Enterprise customers who go through a sales conversation.
Glimpse shows channel breakdown across eight platforms, including TikTok, Reddit, and LinkedIn, for any tracked trend; Google Keyword Planner has no social or channel-level breakdown, its data is Google Search only.
Google Keyword Planner requires setting up a Google Ads billing profile even if you never spend on ads; Glimpse's Chrome extension requires no account or billing setup at all to see limited free data.
Google Keyword Planner includes CPC data for every keyword, a direct commercial-intent signal; Glimpse's core product does not surface CPC or paid-search cost data anywhere in its feature set.
Glimpse and Google Keyword Planner are both free to start, both come straight or one step removed from Google's own data, and both get recommended as a "check this first" tool. They are not solving the same problem, though. Google Keyword Planner exists inside Google Ads and answers a keyword-level question: how many people search this term, and what does a click cost. Glimpse exists as a Chrome extension layered on top of Google Trends and answers a trajectory question: is this topic growing, where is it gaining traction, and where is it likely headed next year. Keyword Planner requires a Google Ads account and shows ranges unless you are actively spending; Glimpse requires no account at all for its free tier but hides its paid pricing behind a sales conversation.
The tools at a glance
Glimpse
Google Trends supercharged with absolute search volume, trend forecasting, and channel breakdown
Glimpse starts from a specific complaint: Google Trends has genuinely useful data, but its 0-100 relative index makes it nearly impossible to act on. The free Chrome extension rewrites the Google Trends interface in place, adding real monthly search volume next to the index curve you already see, plus a "People Also Search" panel that expands a single lookup into related keyword ideas with their own volume and growth figures.
Past the free tier, Glimpse adds Trend Alerts, a channel breakdown across TikTok, Reddit, YouTube, LinkedIn, Instagram, Twitter, Facebook, and Pinterest, and a forecasting model that strips out seasonal noise and projects a topic's trajectory a year out with a claimed 95%+ backtested accuracy. The platform points to public calls on trends like pickleball, Substack, and Perplexity AI as evidence the forecasting model has real predictive value, not just retrospective curve-fitting.
The friction is pricing opacity and API access. Nothing past the Free tier is listed on the site; Pro and Enterprise both require a signup or sales conversation before you learn the cost, which is unusual for a tool whose entry point is otherwise zero-friction. API access is Enterprise-only, so a self-serve Pro subscriber gets forecasting and channel data but still cannot pull it programmatically.

Google Keyword Planner
Free keyword research and forecasting tool from Google, built into Google Ads with search volume data direct from the source
Google Keyword Planner is a free tool built into Google Ads, designed for advertisers planning paid search campaigns but used by SEOs for as long as it has existed because the data comes straight from Google rather than a third-party panel or crawler estimate. Enter a seed keyword, phrase, or landing page URL and it returns related suggestions with search volume ranges, competition level, and average CPC.
The catch that shapes almost every review of the tool is volume precision. Accounts without active Google Ads spend see search volumes as wide ranges, such as 1,000 to 10,000 monthly searches, rather than a specific number; only accounts with active ad spend get more precise monthly averages. That makes the tool most useful to teams already running paid and organic search together, and directional at best for a pure SEO team with no ad budget.
What Keyword Planner does have that Glimpse does not is CPC data on every keyword and a genuinely free, developer-accessible API through the Google Ads API with a developer token. There is no keyword difficulty score, no SERP analysis, and no trend-trajectory forecasting; its forecasting tool projects clicks, impressions, and cost for a paid campaign at a given bid, which is a different job than predicting where organic interest in a topic is headed.

Which should you choose?
If a team could only run one of these, Google Keyword Planner is the stronger default: it is unconditionally free with no upsell, gives CPC and volume data that Glimpse does not offer at all, and its API is available to any developer with a token rather than gated behind an Enterprise sales call. Glimpse earns its place as a second tool, not a replacement, because it answers a question Keyword Planner cannot: not how many people search a term today, but whether interest in it is accelerating and where that interest is showing up outside of Google Search.
Bottom line
Use Google Keyword Planner as the default free source for search volume and CPC on any keyword list, since it requires no evaluation period and its API is genuinely accessible to developers. Layer Glimpse's free Chrome extension on top of Google Trends specifically for topic-level trajectory and channel-breakdown work, and only escalate to a Pro or Enterprise conversation once the forecasting and alerting features prove worth paying for. Neither tool replaces a dedicated keyword research platform for SERP-level competition data or keyword difficulty scoring.
Frequently asked questions
Is Glimpse or Google Keyword Planner better for getting exact search volume numbers?
Google Keyword Planner gives more precise search volume, but only for accounts with active Google Ads spend; without spend, it shows ranges like 1,000 to 10,000 monthly searches. Glimpse's free tier shows limited real numbers directly inside Google Trends, and its Pro plan unlocks full absolute search volume, though Glimpse's Pro pricing is not published and requires a signup to see.
Do I need a Google Ads account to use Google Keyword Planner?
Yes, you need a Google Ads account and billing profile set up to access Keyword Planner, even if you never spend money on ads. Glimpse requires no account or billing setup at all for its free Chrome extension tier, which makes it the lower-friction option for someone who just wants to check a topic's trend data.
Can Glimpse tell me the CPC for a keyword the way Google Keyword Planner can?
No. Glimpse does not surface CPC or paid-search cost data anywhere in its feature set; its focus is search volume, growth rate, channel breakdown, and forecasting. Google Keyword Planner shows a low and high CPC range for every keyword, which makes it the better source if commercial intent pricing is what you need.
Which tool is better for forecasting where a trend is headed next year?
Glimpse is purpose-built for this: its forecasting model removes seasonality and noise from historical search data and projects a topic's trajectory 12 months out, with a claimed 95%+ backtested accuracy. Google Keyword Planner has a forecasting tool too, but it projects clicks, impressions, and cost for a paid campaign at a set bid, which answers a different question than organic trend direction.
Does either tool have an API I can build with for free?
Google Keyword Planner's data is accessible through the Google Ads API using a developer token, which is available to any developer without a sales conversation. Glimpse restricts API access to its Enterprise tier, which requires contacting sales, so self-serve Free and Pro users on Glimpse cannot pull data programmatically at all.
Is it worth using both Glimpse and Google Keyword Planner together?
Yes, for most content and SEO teams. Google Keyword Planner gives you Google-sourced volume and CPC for specific keywords you already know you care about, while Glimpse's free extension shows whether a topic is accelerating and where it is gaining traction across platforms Google Search alone will not reveal. They cover different stages of the same research process rather than competing for the same job.
