Google LSA vs Google Search Ads: Which Channel Wins for Home Services?

Most home-services operators pick LSA or Search Ads based on whichever rep called them last. Both channels work. They just win in different conditions. Here is how we decide.

The 30-second model

• LSA wins on raw cost-per-lead in mature markets where you already have reviews.
• Search Ads win on control: keywords, landing pages, audience, geography, ad copy.
• LSA owns the top of mobile SERPs. Search Ads own the long tail of intent.

Unit economics that actually matter

Forget cost-per-click. Track these four numbers per channel, every week:

1. 01Cost per qualified lead (not raw lead).
2. 02Booked-call rate from qualified lead.
3. 03Closed-deal rate from booked call.
4. 04Revenue per closed deal, net of refunds and chargebacks.

Multiply across and you get true revenue per dollar of ad spend. That is the only number that lets you compare channels honestly.

When LSA wins

• You have 40+ Google reviews at 4.7+ stars.
• You service emergency calls (drain backup, no heat, leak).
• Your closers can answer the phone live during ad hours.
• Your service area is dense enough that you do not waste impressions on out-of-zone leads.

When Search Ads win

• You sell higher-ticket installs (HVAC replacement, roof, windows, remodel).
• You want to control the landing experience and capture form leads.
• You are testing new service lines that LSA categories do not map to cleanly.
• You need geographic precision LSA cannot give you.

Running both without overlap

The mistake is bidding against yourself. Use LSA for emergency and high-frequency repair searches. Use Search Ads for replacement, install, brand, and competitor terms. Negative-match LSA categories out of your Search Ads campaigns so impressions do not collide.
