Meta shows your ad to people who look like your buyers. ChatGPT shows it under an answer to a question about what you sell. Here is how the 2 compare.
Meta is cheaper per click, has years of public benchmarks and the most complete tracking. ChatGPT puts your ad under an answer to a question about what you sell, needs very little creative, and is still in beta with no official benchmarks. If Meta already works for you, keep it running and test ChatGPT beside it.
| Facebook and Instagram | ChatGPT | |
|---|---|---|
| Who can see your ad | 3.6 billion people use a Meta app every day (June 2026) | 1.2 billion people use ChatGPT every week. Ads reach only adults on the Free and Go plans |
| How you choose who sees it | Location, age, customer lists, site visitors and interests. Advantage+ audience is on by default and can go past your settings | Context hints that describe your offer, plus countries, regions, devices and customer lists of 25,000 or more |
| What the ad looks like | Images, video, Reels, Stories, carousels, product catalog ads, lead forms and chat ads | A square image, a title of 16 to 24 characters and a description of 32 to 48, plus product cards from a feed |
| What you pay for | Views or clicks, never per sale | Views or clicks, never per sale |
| Minimum budget | No fixed minimum. With a cost per result goal, Meta asks for a daily budget of at least 5 times that goal | $25 a day, €15 or £15 |
| Most it can spend in a day | 75% over your daily budget, and no more than 7 times it in a week | 2 times your daily budget, and no more than 7 times it in a week |
| Price per click (US median) | $0.60 on traffic campaigns and $1.80 on lead campaigns | OpenAI suggests starting bids of $3 to $5. 15 public campaigns had a median of $4.41 |
| Published benchmarks | Many, from large samples | None from OpenAI yet |
| Learning rules | An ad set leaves learning after about 50 results in a week | No published number. OpenAI asks for fewer, better funded campaigns |
| Who creates the ad account | You, or your agency on your behalf | You. Your agency can join only after you create it |
| Ad review | Most ads within 24 hours | No published time. Business verification can take up to 7 business days |
On Facebook and Instagram your ad follows people. Meta looks at who they are and what they do on its apps and on your site, and finds more people like your buyers. In April 2025 Meta told advertisers that "the focus has shifted from niche targeting to creative diversification as the best lever." Your ads now do most of the targeting, because each different ad finds a different group of people.
On ChatGPT your ad follows the conversation. There are no interests and no lookalike audiences. You describe what you sell, who it helps and when it is useful, and OpenAI shows your ad below answers where that description fits. Graphite and Similarweb found that 51% of ChatGPT ad views happen in the first 3 messages of a chat, and that when someone names a brand in a question, ads from its competitors often appear.
That changes what you are buying. On Meta you catch someone who was scrolling. On ChatGPT you show up while someone is asking about the problem you solve.
Meta clicks are cheaper. WordStream's 2026 study of 1,829 US campaigns found a median of $0.60 per click on traffic campaigns, $1.80 on lead campaigns and $27.39 per lead. Triple Whale puts the median Meta cost per 1,000 views for online stores at $15.06, for August 2025 to July 2026.
ChatGPT clicks cost more. OpenAI suggests starting at $3 to $5 a click, and 15 public campaigns billed in dollars had a median of $4.41. When we tested the bid meter in a euro account, bids from €2.00 up were rated likely to deliver.
The price of a click is only half the story. The numbers that decide it are your cost per sale and how many of the buyers are new to you. OpenAI's measurement partners published the first figures in October 2026. Fospha found that ChatGPT ads brought 83% more revenue per 1,000 views than the paid social average for the same advertisers. Triple Whale found that 93% of the visitors ChatGPT ads sent to Portland Leather Goods were new to the store. OpenAI published both, and both partners sell measurement, so treat them as early signals. Nobody has yet published a test that spends the same budget on both platforms and compares the cost per sale.
Meta runs on volume. Its guidance asks for many ads with different themes, messages and visuals, and video for Reels and Stories. One brand Meta quoted went from 3 or 4 new ads a week to almost 50. Adding a new ad also restarts the learning phase of its ad set.
A ChatGPT ad is a square image, a title of up to 24 characters and a description of up to 48. Variety still helps. OpenAI says a varied set of ads lets the system find more conversations where one of them fits, and Graphite found that the 50 biggest ChatGPT advertisers run a median of 191 different ads each.
One setting needs your attention. From October 29, 2026, OpenAI turns on creative enhancements for every campaign. OpenAI can then rewrite your titles and descriptions, resize your images, change the page your ad links to and translate the ad, and these versions can run without you seeing them first. You can switch it off in Ads Manager. If your offer has compliance rules, or your landing page carries its own tracking, decide before that date.
Meta has the deeper toolkit: its pixel, the Conversions API, lift tests, and attribution of 1 or 7 days after a click and 1 day after a view. It also changed twice in 2026. The 7 day and 28 day view windows left Meta's reporting API in January, and since late March only link clicks count as clicks for website sales.
ChatGPT has its own pixel and Conversions API, attribution of 7, 14 or 30 days after a click and 0 or 1 day after a view, and 10 attribution partners, including Triple Whale and Northbeam. Reporting is slower. Clicks show within about 15 minutes, spend runs about 7 to 8 hours behind, and conversions take 24 to 48 hours. Agencies told Digiday in October 2026 that gaps in conversion tracking are keeping their ChatGPT budgets at test level.
Meta allows more categories but limits how you target and track some of them. Since January 2025, US ads for financial products sit in a special category: no zip code targeting, a 15 mile minimum radius around a city, and age and gender left open. Housing and jobs follow the same rules. Websites that Meta files under health and wellness can lose the right to optimize for purchases.
ChatGPT closes some categories completely. OpenAI bans supplements sold outside major retail channels, health coaching, credit repair, debt relief, payday loans, job listings and individual home rentals or sales. Health, finance and legal ads are mostly limited to the US, with extra review.
Keep it running. Test ChatGPT with money you can afford to spend on finding out. At the $25 daily minimum, one week can cost up to $175. Set up conversion tracking before the first ad goes live, send each ad to the page about that one offer, and judge the test on what each sale cost you.
Based on each platform's own help pages and on the studies named below, as we read them on October 20, 2026. Prices and rules change often, so check the current numbers before you spend.
