What each channel does
| Streaming TV (CTV) | Meta (Facebook and Instagram) | |
|---|---|---|
| Its job | Make the household remember your store and your offer | Turn a shopper's interest into a tap, a message, a lead or a call |
| Screen | The living-room TV, full screen, usually unskippable | The phone, in a feed, skippable in a second |
| Targeting | Households by ZIP code, city, county or DMA, plus audience data | People by location radius and Meta's own signals; ZIP codes only outside the financial category |
| Best creative | 15 and 30 second spots, sound on, one clear message | Vertical video and inventory ads, captions, the vehicle in the first second |
| What to measure | Households reached, frequency, and lift in calls, branded search, site visits and showroom traffic against a holdout | Leads, messages, calls and vehicle detail page views, read by ZIP code against the same holdout |
Neither channel replaces the other. A spot on the TV does not hand the viewer a button to press; a feed ad does not get thirty seconds of attention on a 65-inch screen. Together, the TV spot makes the Meta ad feel familiar when it shows up on the phone.
The rule that changes the plan: Meta's financial ad category
Since January 21, 2025, advertisers in the United States, or showing ads to people in the United States, must declare the Financial Products and Services special ad category for campaigns that promote financial offers. It replaced the old Credit category, and Meta's own list names auto loans, long-term financing and 0% APR installment payments.1 Ads can be rejected if the category is not chosen.1
Declaring the category changes the targeting:12
- No ZIP or postal code targeting, and no location exclusions.
- A minimum 15-mile radius around any city, address or pin in the US.
- Age fixed at 18 to 65+, all genders, and no lookalike audiences.
- Detailed targeting limited, while customer-list custom audiences can still be used if they come back eligible.
What it means for the plan. Streaming TV can still be aimed ZIP code by ZIP code; a Meta ad that mentions a payment, an APR or financing cannot. So keep the ZIP-precise Meta work for inventory, service, people and brand stories, run finance offers inside the category with a radius, and let the streaming flight carry the store's story into the exact ZIP codes you want. Finance terms in a TV spot carry their own disclosure rules, so they go through compliance review either way.
How the two feed each other
- The TV spot sends people to search and to your site. Most TV screens are not clickable, so the response shows up as branded searches, direct visits and calls in the households that saw it.
- The Meta Pixel catches the visit. Website visitors become a custom audience on Meta, so the household that saw the spot last night can see your inventory on the phone today.
- Inventory ads show the exact vehicle. Meta's automotive inventory ads build each ad from a vehicle catalog and the pixel, so a shopper who viewed a used truck on your site can see that truck, with its price, in their feed. They run under the Sales objective with Advantage+ catalog ads turned on and a catalog of type Auto, then Vehicles.3
- One story across both. The same people, the same offer and the same store appear in the 30-second spot and the 6-second vertical cut, so each one reminds the shopper of the other.
How to split a budget between CTV and Meta
Start from households, not from a percentage. Auto streaming campaigns are often quoted around a $30 CPM, the cost of a thousand impressions.4 The arithmetic for a streaming flight is simple:
Households you can reach = budget ÷ CPM × 1,000 ÷ weekly frequency × weeks, as long as the platform can find that many households in your ZIP codes.
Example: $6,000 over six weeks at a $30 CPM buys about 200,000 impressions. At four views per household per week, that reaches about 8,300 households every week for six weeks.
Then check the other side: Meta should already be running always-on for inventory and service, with enough budget to keep learning. Add the streaming flight on top, in flights of six to eight weeks, rather than cutting Meta to pay for it. If the store cannot afford both at a level that reaches enough households, it is usually better to run Meta well than to run both thinly.
These are planning numbers, not a quote. Each platform gives its own reach estimate for your ZIP codes before you spend anything. See what CTV costs for a dealership.
Measure them against the same holdout
Hold a few comparable ZIP codes out of the streaming flight. Then read both channels the same way, exposed ZIP codes against holdout ZIP codes, before and during the flight:
- Phone calls and their source.
- Branded Google searches and direct website visits.
- Meta leads, messages and calls by ZIP code.
- Vehicle detail page views and showroom visits.
If calls and branded searches rise in the exposed ZIP codes and not in the holdout, the TV flight is doing its job, and the Meta numbers in those ZIP codes should rise with them. The full method is in how to measure CTV for dealerships.
Creative: one story, cut for each screen
Streaming viewers are less patient with weak ads than you might think: in research published by Vibe, 80% of viewers said a bad ad is worse than no ad at all.5 Build one story and cut it three ways:
- 30 seconds for TV, when the story or the disclosures need the time.
- 15 seconds for TV, one message and the store, for frequency without fatigue.
- Vertical 6 to 15 seconds for Meta, captioned, with the vehicle or the person on screen in the first second, ending on a clear next step.
Rotate several spots across a flight rather than repeating one. Free, ad-supported apps are filling their breaks faster than they used to, which makes repetition wear thin sooner; see Free Streaming Means Fuller Breaks.
