Most lists of the most expensive keywords on Google rank single terms with no method attached. We went to Google’s own source instead. On 8 November 2026 we pulled 7,012 US keywords from Keyword Planner across nine high-value verticals. The answer is not close: legal keywords have a median top-of-page bid (high range) of $286.03. Education, the next vertical, sits at $65.78, so legal is more than four times higher. And 137 of the 480 legal keywords carry a high-range bid of $500 or more.
The Short Answer: Legal Owns the Top of the List
In our sample, 27 of the 30 most expensive Google keywords are legal searches, and nearly all of them are about accidents: car wrecks, collisions, crashes, construction accidents and injury attorneys “near me”. The three exceptions are a marketing query that is really about law firms (“law firm digital marketing agency”), and two brand terms, one insurance and one business lender.
Legal is expensive all the way down, too. Of 480 legal keywords, 405 have a high-range bid of $100 or more. In Healthcare, which we seeded with terms like drug rehab, hair transplant and dental implants, only 24 of 950 keywords clear $100. Across all nine verticals, 149 keywords reached $500 or more, and 137 of those are legal.
What the Number Actually Measures
Every figure in this study is Keyword Planner’s top of page bid, not a cost per click, and the difference matters. Google’s Keyword Planner help page defines the high range as “an approximation of the 80th percentile” of what advertisers have historically paid to show at the top of the page, and the low range as an approximation of the 20th percentile. The same page says bid range statistics show bid information from the last 30 days, for the location and network you choose, and that reaching the top of the page depends on “a combination of bid, quality score, and other factors.”
So a $785.43 high-range bid on “accident attorney” means roughly one in five top-of-page bids on that term in the last 30 days was at or above that level. It does not mean anyone paid $785.43 for a click. Google’s own actual CPC definition notes advertisers are “often charged less — sometimes much less” than their maximum bid. We rank by the high range and show the low range for the spread.
Third-party CPC columns in Ahrefs or Semrush are their own estimates, a different metric from a different method, so expect them not to match. More in Keyword Planner vs Ahrefs vs Semrush.
The 15 Most Expensive Keywords in Our Sample
The chart below ranks the top 15 by high-range bid, after removing seven keywords that share an identical capped figure (explained in the Methodology section).
| Keyword | Vertical | Monthly searches | Low range | High range | Competition |
|---|---|---|---|---|---|
| road rage lawyer | Legal | 110 | $74.52 | $1,137.03 | Low |
| local accident attorneys | Legal | 110 | $167.70 | $1,076.79 | High |
| law firm digital marketing agency | Marketing & SEO | 320 | $48.15 | $1,069.41 | Low |
| vouch insurance | Insurance | 1,900 | $17.49 | $1,033.22 | Medium |
| good lawyer for car accident | Legal | 140 | $230.83 | $981.67 | Medium |
| lawyer car wreck | Legal | 2,900 | $179.54 | $922.21 | Low |
| collision lawyer | Legal | 590 | $192.36 | $885.47 | High |
| accident and injury attorney near me | Legal | 2,400 | $198.12 | $868.97 | Medium |
| best accident lawyers | Legal | 480 | $172.20 | $833.56 | Medium |

| i need a car accident lawyer | Legal | 170 | $167.15 | $811.50 | Medium |
| traffic collision lawyer | Legal | 2,400 | $135.29 | $808.28 | Medium |
| auto wreck lawyers | Legal | 390 | $119.57 | $802.39 | Low |
| collision lawyer near me | Legal | 390 | $171.64 | $786.05 | High |
| accident attorney | Legal | 14,800 | $170.15 | $785.43 | Medium |
Most are small keywords: seven of the 15 have fewer than 400 monthly searches. In this sample the top bids sit on narrow, high-intent phrasings, not head terms. The low range matters too. On the legal terms it sits between $74.52 and $230.83, a fraction of the high figure. On “vouch insurance” it is $17.49 against a high of $1,033.22. A spread that wide suggests a few aggressive bidders set the top of the range while the typical click is far cheaper.
Expensive Keywords by Industry
The chart below shows the median high-range bid for each of the nine verticals.
| Vertical | Keywords | Median low | Median high | 90th percentile high | Keywords at $100+ (high) |
|---|---|---|---|---|---|
| Legal | 480 | $41.84 | $286.03 | $638.66 | 405 |
| Education | 783 | $13.56 | $65.78 | $116.90 | 126 |
| Software & SaaS | 699 | $10.97 | $64.24 | $166.16 | 174 |
| Insurance | 941 | $13.60 | $54.76 | $147.94 | 252 |
| Marketing & SEO | 645 | $10.80 | $47.38 | $105.56 | 78 |
| Finance | 932 | $9.06 | $41.41 | $110.54 | 129 |
| Home services | 913 | $6.58 | $40.76 | $135.37 | 212 |
| Real estate | 669 | $6.80 | $30.30 | $159.04 | 142 |
| Healthcare | 950 | $5.08 | $26.47 | $84.96 | 24 |
Legal’s median low-range bid ($41.84) is higher than the median high-range bid of four other verticals. Healthcare finishes last; a plausible reason, which this data can’t confirm, is that seeds like “dental implants” and “plastic surgery” return many informational and cost-research queries that pull the median down.
Medians Hide the Tail: Where the Ranking Flips
Sort the same table by the 90th percentile instead of the median and the order changes, which is the part most lists of expensive keywords by industry miss. Education is second by median but only sixth by 90th percentile ($116.90). Real estate is eighth by median ($30.30) but third by 90th percentile ($159.04). Software & SaaS ($166.16) moves into second.
Education is uniformly pricey: most degree and course terms cost something, but few cost a fortune. Real estate is mostly cheap with an expensive tail: our data shows the tail exists, not which queries form it, so pull your own local terms to find it. SEO Rocket’s competitor gap analysis then shows which of those terms rivals already rank for. Home services looks similar: a $40.76 median, but 212 keywords at $100 or more. In a skewed vertical, the average is close to useless. Find the pocket.
High-Volume Keywords That Still Cost $500 or More
Expensive and high-volume rarely overlap, but in legal they do. Among keywords with 10,000 or more monthly searches, the 12 most expensive are all legal.
- accident attorney: 14,800 searches, $785.43 high range
- accident lawyer: 18,100 searches, $729.48
- car accident attorney: 40,500 searches, $634.79
- lawyer for auto accident: 246,000 searches, $622.54
- auto accident attorneys near me: 60,500 searches, $570.16
- car accident lawyers near me: 165,000 searches, $530.91
“Mesothelioma lawyer” was one of our legal seeds, and “mesothelioma attorneys” (12,100 searches) came in at $376.23, below every accident term on that list. The only non-legal entries in the high-volume top 15 are two finance terms, “business term loan” ($323.98) and “business line of credit” ($303.84). Law firms should read SEO for personal injury lawyers.
Google’s “Competition” Label Does Not Mean “Expensive”
“Lawyer car wreck” has a $922.21 high-range bid, and Keyword Planner rates its competition as Low. Google defines competition as “the number of advertisers that showed on each keyword relative to all keywords across Google.” It counts how many advertisers show up, not how much they bid.
Among our top 30 keywords, 10 are rated Low, 16 Medium and only 4 High. A handful of law firms bidding heavily can produce an enormous bid range with Low competition. Filter a Keyword Planner export by “High competition” to find valuable terms and, in our top 30, you would keep only 4. Sort by the bid columns instead.
What a $700 Click Means for SEO
Bid data is ad data, but its best use is organic. A high bid means advertisers have found the visitor worth that much, which makes it the best free signal of commercial value you can get. It also tells you the top of that results page will be crowded with ads, because those bids pay to appear above organic results.
A worked example, with a made-up traffic figure to show the method. Suppose a page earns 500 organic clicks a month from “accident lawyer”. At that keyword’s low-range bid of $149.41, those 500 visits represent about $74,700 a month in bids. That is not revenue, and actual CPCs are often lower. But it explains why law firms fund content that would look absurdly expensive in a lower-value niche. Our guide to calculating SEO ROI walks through turning that into a defensible number, and the free SEO ROI Calculator does the arithmetic. For the paid-versus-organic trade-off itself, see SEO vs PPC.
How to Use Bid Data to Prioritise Keywords
Bid data is one input, never the whole decision. The rules we use in client work:
- Use the low range for value, the high range for pressure. The low range is the safer estimate of what a click is worth. The high range tells you how hard the top bidders are fighting.
- Compare clusters, not single keywords. One keyword can carry a freak bid, like the $1,282.40 figures we excluded. A same-intent cluster’s median is far more stable.
- Weigh value against difficulty. A $600 legal term you cannot rank for in two years is worth less to you than a $40 home-services term you can win this quarter. Our keyword prioritization framework puts value, difficulty and intent on one sheet.
- Check intent before you chase the price. Nearly every term in our top 30 is a hiring or buying search, many of them local. An informational article will not convert that searcher. See commercial intent keywords.
- Re-pull before you decide. Google’s bid ranges cover the last 30 days and move with the market, so last year’s export is a weak basis for this year’s plan.
SEO Rocket’s keyword research does this in one chat: ideas from real Ahrefs data with volume, keyword difficulty and a CPC estimate side by side, so you can rank a cluster by value and winnability. That CPC is Ahrefs’ estimate, so use it to compare keywords and check bid ranges in Google Keyword Planner before a budget decision. Once the money pages are live, SEO Rocket’s rank tracking and client dashboard show whether the expensive terms are moving, the same loop behind a playbook proven across 1,000,000+ ranking pages.
Methodology and Limitations
Source. Google Ads API Keyword Planner, keyword ideas endpoint, set to the United States, English and the Google Search network, pulled on 8 November 2026. Average monthly searches are Google’s 12-month average.
Sample. Five seed keywords per vertical across nine verticals (for example “personal injury lawyer”, “crm software”, “online mba”, “sell my house fast”) returned 9,000 ideas. We kept unique keywords with at least 100 monthly searches and a bid estimate: 7,012 keywords. Each keyword was assigned to the first vertical whose seeds returned it. That is why “law firm digital marketing agency” counts as Marketing & SEO, not Legal.
Excluded figures. Seven keywords shared an identical high-range bid of $1,282.40 across unrelated verticals: two truck-accident legal terms, two Allstate home insurance terms and three Sage ERP terms. Identical values on unrelated keywords look like a ceiling in the estimate rather than real bidding, so we left them out of the ranked lists. They remain in the vertical totals above.
Limits. This is a seed-driven sample, not Google’s whole index; other seeds would surface other keywords. It covers one country and one language, and bid ranges shift month to month. Brand terms, like the Vouch and OnDeck entries, can carry bids that say more about brand competition than about the category.
FAQ
What is the most expensive keyword on Google?
In our 7,012-keyword US sample, it was “road rage lawyer”, with a top-of-page bid (high range) of $1,137.03. Our sample does not cover every keyword Google sells, so any “number one” depends on the sample and the date it was pulled.
Which industry has the most expensive keywords?
Legal, by a wide margin: a median high-range bid of $286.03, against $65.78 for Education, the next highest of the nine verticals we tested.
Is top-of-page bid the same as CPC?
No. It is Google’s estimate of the 20th and 80th percentile of bids to appear above organic results. Your actual cost per click is often lower than your bid.
Should I target the most expensive keywords for SEO?
Only if you can serve the intent and realistically rank. High bids signal valuable visitors but also crowded results pages and strong competitors, so pair bid data with difficulty and intent.
