Google Local Service Ads (LSA) are the most powerful lead generation tool available to local service businesses — and they're still underused by most businesses that qualify for them. This guide explains exactly what LSAs are, how the Google Guaranteed badge works, which businesses can use them, and what results to realistically expect.
Google Local Service Ads are a pay-per-lead advertising format that appears at the very top of Google search results — above standard PPC ads, above the map pack, above organic results. They display your business name, star rating, years in business, and a green Google Guaranteed or Google Screened badge. When a customer clicks, they see your profile and can call or message you directly. You only pay when a verified customer contacts you through the ad — not per click, per impression, or per view.
Google Guaranteed is for home service businesses — HVAC, plumbing, electrical, roofing, general contractors, locksmiths, and similar trades. It requires a background check and license verification. Google's satisfaction guarantee backs jobs booked through the ad — if a customer is unsatisfied, Google may refund up to the job amount. Google Screened is for professional services — lawyers, financial advisors, real estate agents, and others. It requires license verification and background check but does not include the satisfaction guarantee.
Home services: HVAC, plumbing, electrical, roofing, general contracting, cleaning services, pest control, landscaping, locksmithing, moving, appliance repair, and more. Professional services: law firms, financial advisors, real estate agents, tax preparation, and others. Healthcare: dentists, chiropractors, optometrists, and others. Availability varies by service category and location — not all categories are available in all markets. YelloPost verifies LSA eligibility for every client during onboarding.
To run LSA you must complete Google's verification process: business license verification (upload current license), insurance verification (certificate of insurance), background check for business owners and employees who work in customers' homes, and Google Business Profile verification. The process typically takes 1–3 weeks. While it feels like a hurdle, completion gives you the Google Guaranteed badge — a significant trust signal that non-verified competitors cannot display.
LSA uses a pay-per-lead model. You set a weekly budget and a maximum lead price. Google charges per verified lead — a phone call or message through the ad. Lead prices vary by category and market: HVAC leads typically cost $15–$60, legal leads $50–$150, dental leads $20–$80. You can dispute leads that are clearly wrong-category calls, duplicates, or spam — disputed leads are credited back if Google agrees. LSA leads are consistently the highest-quality leads in our client portfolio.
Your LSA profile determines your ranking within the LSA section and your conversion rate. Optimization priorities: maintain a high response rate (answer calls and respond to messages quickly), maintain a high review count and rating (LSA pulls from your Google Business Profile reviews), set accurate service areas and hours, complete all profile fields, and resolve disputes promptly. Businesses with response rates above 90% and 50+ reviews consistently outrank and outconvert competitors with lower engagement.
LSAs and standard Google Ads serve different roles and work best together. LSA captures the highest-intent searches at the top of the page on a pay-per-lead basis. Standard Google Ads capture a broader range of relevant searches across more keywords on a pay-per-click basis. Running both simultaneously creates comprehensive coverage — LSA wins the pay-per-lead inventory, Google Ads captures everything else. Businesses running both typically see 30–50% more total leads than those running only one.
