High-Volume Google Ads Keywords Cost 3% More per Click, Not Less

"zillow" is searched 20.4 million times a month and costs $0.08 a click on Google Ads. "truck accident lawyer" is searched 49,500 times and costs $509.15. One keyword is searched four hundred times as often as the other, and costs a tiny fraction as much, but neither price has anything to do with how often it is searched.

Many advertisers assume high-volume keywords are cheaper per click, because more searches spread out the bidding, or that small "long-tail" keywords are the cheap corner of the market. Both assumptions shape real budgets: which keywords get added, which get cut and how much each campaign is expected to cost.

The data says neither is true. Keywords searched 100,000 or more times a month cost $12.00 per click, 3% more than low-volume keywords, and the middle band is the cheapest. What sets the price of a click is the value of the customer behind the search, not the number of people searching.

In September 2026 we took 18,477 US keywords with a Google Ads Keyword Planner price above zero, each searched at least 2,900 times a month, and sorted them into three bands by monthly search volume: 2,900 to 9,999 searches, 10,000 to 99,999 and 100,000 or more. For each band we calculated the average and median cost per click and the share of keywords costing $10 and $50 or more, then measured the correlation between volume and price across all keywords.

Cost per click is what an advertiser pays each time someone clicks its ad. The median is the middle keyword in a band: half cost less, half cost more. A rank correlation runs from -1 to 1 and measures whether keywords with more searches tend to cost more (above 0) or less (below 0); 0 means no relationship. Search intent describes what the searcher wants: navigational searches look for a specific brand or site, and commercial searches compare options before buying.

That is 3% more than the $11.65 average for keywords searched under 10,000 times a month. The typical keyword tells the same story: the median high-volume keyword costs $4.64, 6% more than the $4.36 of the median low-volume keyword.

The cheapest band is the middle one, at $9.64 on average and $4.04 at the median. With the lowest prices in neither the smallest nor the largest keywords, there is no simple "more searches, lower price" rule, and no reverse rule either.

Across all 18,477 keywords, the rank correlation between monthly searches and cost per click is -0.02. Knowing how often a keyword is searched gives no useful hint about its price. The three bands land within about $2.40 of each other on average and within 60 cents at the median.

Prices are set by the advertisers in each auction, and they bid on what a customer is worth to them. A search for a truck accident lawyer can lead to a case worth a great deal, so law firms bid hundreds of dollars for it. A search for a brand name mostly leads to that brand's own site, so few advertisers bid at all. Volume changes how many clicks are available, not what each one costs.

The share of keywords costing $10 or more per click is 29% in the lowest band, 26% in the middle band and 28% in the top band. The share costing $50 or more is 4.2%, 2.9% and 3.7%. An expensive keyword is as likely to be a small one as a big one.

The biggest keywords include several brand searches, which are cheap: "zillow" at $0.08, "home depot near me" at $0.96 and "autozone auto parts" at $0.20. The top band has a slightly larger share of these brand searches, 13% of its keywords with an intent label against 8.4% in the lowest band. That tilt would pull its price down, but the top band also holds expensive comparison searches, 36% of its labeled keywords against 41% in the lowest band, and the two cancel out.

Do not pick keywords by volume and assume the price will follow. Check the estimated cost per click of every keyword you plan to add, because a keyword searched a few thousand times a month can cost as much as one searched a million times.

Long-tail keywords are not automatically cheaper either, at least down to 2,900 searches a month. Their advantage, where they have one, comes from intent: a precise search tends to come from someone closer to buying. Judge each keyword on cost per lead, which combines the click price with how often that click turns into a customer. A google ads agency such as Suff Digital builds keyword plans around cost per lead rather than volume alone.
