ChatGPT Ads for service businesses put your firm, practice or crew beside the ChatGPT conversations where buyers choose who to call, and WKND builds, tracks and manages those campaigns in OpenAI Ads Manager. You already convert demand from Google or Meta. ChatGPT Ads adds conversational, mid-decision intent to a funnel that is proven to close, judged on qualified calls, not clicks.

Why ChatGPT Ads fit service businesses
Service buyers explain their problem before they pick a provider. That conversation now happens in ChatGPT, and the ad sits below the answer while they compare.
The buyer is mid-decision: they have described the job, the deadline and the budget.
The offer is specific: each ad group matches one service, one market and one landing page.
The result is a conversation: a call, a consultation request or a booked appointment, not a page view.
ChatGPT Ads results for service businesses
A San Francisco law firm cut its cost per lead to $105.11, 58% below Google Search
$105.11cost per lead
58% lowerthan Google Search ($248)
114 leadsin 47 days
$2.62 CPCvs ~$43 implied on Google
Google Search leads cost this San Francisco firm $248 each. It needed a second channel that could add consultations without adding cost. WKND reviewed advertiser eligibility and the firm’s service area before launch, ran ChatGPT Ads next to Google Search for a same-period comparison, and judged the result on intake quality and retained clients, not lead cost alone. From June 15 to July 31, 2026, $11,982 in ChatGPT Ads spend produced 114 leads at $105.11 each. The same spend at Google Search’s $248 CPL buys about 48 leads, so ChatGPT Ads delivered about 66 more. Clicks averaged about $2.62, against an implied $43 on Google, about 16x cheaper. ChatGPT’s click-to-lead rate was lower (2.49% vs 17.43%), and the cheaper clicks more than covered it.
Industry example published by OpenAI: Angi lowered its cost per lead by 34%

OpenAI reports that Angi’s cost per lead fell 34% after introducing conversion-optimized campaigns. The same budget buys about 52% more leads. ROAS improved more than 38% from Q2 to Q3. The initial test covered about 20 home-service categories, including roofing and HVAC, before expanding.
How WKND applies this: Connect relevant project needs to service-specific landing pages, then measure qualified inquiries and booked work.

ChatGPT Ads vs Google Ads vs Meta
Not a replacement. It is a third surface. Each channel captures a different moment in the decision. We run all three; the mix is a budget decision, not a loyalty decision.

FAQ
Common questions
Do ChatGPT Ads work for service businesses?
Yes, when the offer, tracking and intake already work. For a San Francisco law firm, $11,982 in ChatGPT Ads spend produced 114 leads at $105.11 each, against $248 per lead on Google Search.
What counts as a conversion for a service business?
A call, form request or booked appointment your team can act on. WKND maps conversion events to what you actually sell and deduplicates Pixel and Conversions API events with shared event IDs.
How much do ChatGPT Ads cost?
Self-serve campaigns start at a $25/day minimum budget. You choose CPM, CPC or outcome-optimized (oCPC) objectives, set maximum bids at the ad-group level (OpenAI recommends starting CPC bids of $3–5) and pay through a relevance-weighted, second-price auction.
How much does a ChatGPT Ads agency cost?
WKND’s ChatGPT Ads Management Program is $7,800 per month with a 90-day initial commitment. It covers account build, campaign management, creative direction, measurement and reporting, with WKND’s supporting SEO services included. Ad spend is separate, and self-serve campaigns start at a $25/day minimum budget.
How are results measured?
Through the OpenAI Pixel and Conversions API: conversion events matched to your campaigns, deduplicated with shared event IDs, with click references connecting conversions back to the ad. Reporting covers impressions, clicks, spend, CTR, average CPC and CPM, and conversions, and UTM parameters persist into your own analytics.
Should we move budget from Google or Meta into this?
No. ChatGPT Ads is a third surface, not a replacement. We typically fund tests without cutting proven channels, then scale on evidence. Your winning campaigns stay winning while the new channel earns its budget.
Who runs the campaigns?
WKND builds and manages everything inside your own Ads Manager account. You keep the account, the pixel and the conversion history. WKND already manages live ChatGPT Ads campaigns for clients.
