A homeowner with water coming through the ceiling is not going to read your landing page. They are going to call the first plausible number. Google's call ads exist for exactly that moment: the ad shows on a phone, the click places a call, and there is no website between the search and the conversation.
They are not a replacement for search ads. They are a specific tool for a specific kind of search. Here is how to decide.
What a call ad is
A call ad is a search ad format that shows only on devices that can make calls. Instead of sending the click to a URL, the ad's main action is to dial your number. You are charged for the click that initiates the call, whether or not the call connects, though Google does report call duration so you can see what happened.
A verification URL is required, and the ad can optionally include a "visit website" link, but the design intent is call-first.
When call ads win
Emergency and urgent services. Water damage, lockouts, no heat in January, no AC in July, a tree on the driveway. The searcher wants a human now.
Simple services with a phone-based booking process. If most of your bookings happen on the phone anyway, and the website's job is just to make the call happen, the call ad skips the step.
After-hours searches, when your site's form would sit until morning but a person or a voice agent can answer now.
Mobile-heavy queries where the landing page underperforms. If your search campaign shows strong mobile impressions and weak mobile conversions, some of that traffic wanted to call and got a page instead.
When search ads win
Considered purchases. A new roof, a kitchen remodel, a whole-home repipe. The searcher wants to see work, read reviews, and understand the process before they talk to anyone. Sending them straight to a phone call is premature.
Commercial and B2B services, where the buyer is on a desktop and wants to qualify you first.
Anything where the form is the better conversion. If your process depends on collecting details up front (photos, addresses, scope), the landing page is doing work the phone cannot.
Businesses that cannot answer the phone reliably. A call ad that rings to voicemail is the most expensive click in the account. If nobody answers, do not run them.
Running both
Most service businesses end up with both, split by intent. The urgent, phone-natural terms ("emergency plumber," "24 hour," "same day," "near me now") go in a call-ad campaign scheduled for the hours the phone is answered. The considered terms go in a standard search campaign with a landing page.
Keep the campaigns separate so the bidding optimizes each for its own outcome, and use negative keywords to stop the two from bidding on the same query.
Setting up a call ad campaign
Use a tracking number, either Google's forwarding number or your call tracking platform's, so every call is recorded with its source and duration. Without it, you know clicks and nothing else.
Set a minimum call duration as the conversion. A ten-second call is a hang-up or a wrong number. A sixty-second call is a conversation. Define the conversion as a call over a threshold that reflects a real inquiry for your business, so the bidding learns from real calls.
Schedule to your answered hours. Call ads outside them waste money and generate the voicemail that the caller does not leave.
Write for the phone. The headline should say what you do and that you answer. "Emergency Plumber, Answering Now" beats a clever line. Include the service area. Skip anything that requires a click to a page.
Watch the call reports. Duration distribution, time of day, and, if your tracking records calls, the actual content. A high share of short calls means the ad is attracting the wrong searches or the phone is not being answered well.
Tracking beyond the call
The call is the lead, not the job. Connect the call tracking to the CRM so each call becomes a contact with a source, and mark which ones booked. Then, ideally, import the booked jobs back so the campaign optimizes for calls that became revenue rather than calls that merely connected. The call tracking setup for this is the same as for any paid channel.
Call-ad campaigns are part of the paid search work we manage, and the call tracking feeds the CRM so each call becomes a contact.
Frequently asked questions
Do call ads show on desktop?
No. They appear only on devices that can place calls, which is the point.
Are call ads cheaper than search ads?
Not inherently. The cost per click is set by the same auction. What changes is what the click becomes: a call rather than a page view, which for the right service converts far better.
Can I use call ads for Local Services Ads?
LSA is a separate product with its own phone-first design. Many businesses run LSA and a call-ad campaign together, since they appear in different places on the results page.
What if I get a lot of spam calls?
Review the search terms and add negatives, tighten the schedule, and use the call recordings to identify patterns. Some spam is unavoidable; a rising share is a targeting problem.
