A client asked us a simple question last month.
"Should we move some of our Google Ads budget to ChatGPT?"
Fair question. ChatGPT ads went self-serve in May. There is no minimum spend anymore. Clicks start at $3 to $5, while the average Google Search click now costs $5.42. On paper, ChatGPT looks cheaper.
But a cheap click is not a cheap customer.
Google clicks still convert at 8.18% on average. Early ChatGPT data lands between 1% and 4%. So for most businesses, a Google lead still costs less. ChatGPT wins somewhere else. It reaches buyers while they are still comparing options, before they ever type a search.
We run Google Ads for clients every week and have tracked the ChatGPT numbers since launch. Here is what each platform really costs per lead, how buyer intent differs and how to run a fair test.
ChatGPT Ads vs Google Ads at a Glance
ChatGPT figures come from early third-party benchmarks. Google figures come from WordStream's 2026 study of more than 13,000 US search campaigns.
Two rows matter more than the rest. Look at CTR and conversion rate. That is where the cost story flips.
What ChatGPT Ads Actually Cost Right Now
ChatGPT ad pricing changed four times in its first eight months. That is why the numbers you find online disagree so much.
The pricing timeline
If an article still quotes a $200,000 minimum, it is out of date. Today you can start with $25 a day per campaign.
Prices dropped too. The $60 CPM from launch is now the default maximum bid, not the going rate. Most campaigns clear between $25 and $60, with an average around $45. CPC bids clear at $3 to $5, and Ads Manager suggests $3.00 as the starting bid.
Should you buy on CPM or CPC?
Pick CPM if you want reach. You pay for every thousand people who see your ad, whether they click or not.
Pick CPC if you want traffic. You only pay when someone lands on your site. For most businesses testing the channel for the first time, CPC is the safer bet.
What Google Ads Costs in 2026
Google is not cheap either. It just has twenty-five years of data behind the price.
WordStream studied more than 13,000 US search campaigns that ran between April 2025 and March 2026. Here is what the average advertiser paid.
The average click has more than doubled in ten years. It cost $2.32 in 2016. Conversion rates rose in most industries this year, and cost per lead fell for the first time since before 2020.
Your industry matters more than the average. Legal services pay $9.87 a click. Home improvement pays $8.33. At the other end, arts and entertainment pays $1.63 and restaurants pay $2.05.
From our accounts: One lead generation account we manage ran 57 campaigns and spent $18,300 at an average of $3.83 per click. It brought in 3,230 conversions at $5.68 each. A second account spent $117,000, held a 17.55% click-through rate and paid $29.90 per conversion. Both sit well below the WordStream cost per lead average. That is what a mature Google account looks like, and it is the bar any ChatGPT test has to clear.
Cost per Lead Is the Only Comparison That Matters
A click price on its own tells you nothing. You pay for clicks. You earn from leads. So we need both platforms in the same unit.
Turning a CPM into a click price
The average ChatGPT CTR sits at 0.68%, according to Similarweb. That means 1,000 impressions bring about 6.8 clicks. At a $45 CPM, each click costs you roughly $6.60.
That is more than the $3 to $5 CPC bid, and more than the average Google click. CPM only makes sense when your ad fits the conversation well enough to beat the average CTR.
Turning clicks into leads
At a $4 click, ChatGPT needs a conversion rate of about 6% just to match Google's average cost per lead. Some SaaS and B2B advertisers report numbers in that range. Most early data sits lower.
So the cheap click is real. The cheap lead is not, at least not yet.
Why "Google costs $38 CPM" gets it wrong
Several comparison articles say Google Search costs around $38 per thousand impressions. The math does not hold up.
Search advertisers pay per click, not per impression. Using the WordStream averages, 1,000 impressions at a 6.64% CTR bring 66 clicks. At $5.42 each, that is about $360 per thousand impressions. Google is the more expensive impression. It also converts far better.
How Google reads intent
On Google, the buyer tells you what they want. They type a keyword. You bid on it. Match types and negative keywords decide exactly which searches trigger your ad. Someone typing "hire WooCommerce developer Singapore" has already decided to buy. They are choosing who.
How ChatGPT reads intent
ChatGPT has no keyword targeting. You describe your ideal conversation with context hints, and OpenAI matches your ad to chats on that topic.
The difference is how much the user shares first. In a chat, people explain their problem, their budget and their requirements. By the time they click, they have done half the research.
The intent ladder
Commercial intent on ChatGPT is growing fast. First Page Sage found 6.1% of ChatGPT prompts carry transactional intent, against 0.69% on Google. Seer's tracking showed evaluation and comparison prompts made up more than half of the conversations where ads appeared.
That is ChatGPT's real edge. It sits in the comparison stage, where Google only sees the final search.
Measurement Is Where Google Still Wins
Google gives you conversion tracking, GA4, offline conversion imports, remarketing lists and Smart Bidding that learns from every sale.
ChatGPT is catching up. Conversion campaigns arrived in June 2026, and Conversion Optimization became generally available in September. But you still cannot see which prompt triggered your ad or what ChatGPT said before it.
Until that changes, track ChatGPT traffic yourself. Tag every ad with UTM parameters. Send it to a dedicated landing page so its numbers stay separate. Watch your branded Google searches too. When ChatGPT ads work, people often come back later and search for you by name.
Can You Run ChatGPT Ads Outside the US?
Yes, in a growing list of countries. On 24 September 2026, OpenAI opened ChatGPT Ads in Singapore, Malaysia, Indonesia, the Philippines, Thailand, Vietnam and Taiwan. Australia, New Zealand, Japan, South Korea and India came earlier. The platform now runs in more than 60 countries.
Eligible businesses can buy through the self-serve Ads Manager from day one. But almost every benchmark you read today comes from US campaigns. Local CPCs, local competition and local conversion rates are still unknown. The first advertisers in each market will set those numbers.
If your business sits in a country that is not on the list yet, check your eligibility inside Ads Manager before you plan a budget.
How to Split Your Budget Between the Two
Keep Google Search as your core. It is where buyers finish the journey, and it is where your cost per lead is proven.
Then test ChatGPT with 5% to 20% of your search budget. That is the range most practitioners recommend right now.
Here is what a minimum test looks like. $25 a day for 30 days is $750. At $4 a click, that buys about 187 clicks. At a 2.5% conversion rate, you get four or five leads. That is enough to read a signal. It is not enough to reach a verdict.
After four weeks, compare cost per lead. If ChatGPT lands within 1.5 times your Google cost per lead, keep going. Those leads came from the research stage, and some of your later Google conversions started there too. If it lands far above that, pause and rework your context hints.
ChatGPT fits best for SaaS, B2B services and products people research before they buy. It fits worst for impulse purchases and emergency local services. Nobody asks ChatGPT for a plumber while their kitchen floods.
Our Take
Right now, Google is the lead engine and ChatGPT is the research-stage test.
Prices will not stay this low. The businesses that test now will learn the channel while the auction is still quiet.
If you want help setting up both and reading the numbers honestly, our Google Ads team can run the test for you.
