Google Local Services Ads vs Thumbtack (2026): Cost & Leads

Google Local Services Ads: you are paying to compete in Google’s local-services auction when people search for relevant services on Google Search and Maps. Legacy Local Services accounts set an average weekly budget and a bidding mode (Maximize Leads, target cost per lead, or max per lead). Some US accounts have migrated in phases into specialized Performance Max pay-per-lead campaigns in Google Ads (daily average budget, Maximize Conversions; Google says manual max-per-lead and vertical-level tCPA are not supported). Ads are ranked by an auction that Google documents as bid plus overall profile quality—not “pay more, always appear first.” Current screening uses the Google Verified badge (Google Help: a single badge replacing the older Google Guarantee / Google Screened split). The Google Money Back Guarantee associated with Google Guarantee was discontinued for services booked after December 7, 2025.

Thumbtack: you are paying for customer contacts generated inside Thumbtack’s marketplace. Customers search or submit a job on Thumbtack, see professionals, and choose whom to contact. You control services, job preferences, area, hours, an exact lead price per service, and a weekly budget. Thumbtack says customers choose pros directly, competition per lead is limited (it does not publish a headcount), and you communicate with the customer on the platform.

Typical LSA path: Google search → LSA results → customer evaluates the profile (reviews, photos, verification callouts) → call, message, or booking → Google assesses whether that contact is a valid lead → you pay if it is charged. Typical Thumbtack path: customer uses Thumbtack → describes the project → matches/sees professionals from targeting → customer contacts you (direct lead, auto-charge) or you contact an Opportunity (charge if they respond) → you compete to close the job.

What you control before a charge: On LSA, services, service area, hours, lead types (message and booking opt-in), bidding, and budget (legacy weekly or migrated daily average). You do not inspect each searcher before paying. On Thumbtack, targeting and exact lead prices are the pre-charge filter for direct leads; Opportunities let you see a price before you reach out. Neither model is Bark-style “skip this card without paying” for every contact.

Legacy Local Services accounts list three bid modes. Maximize Leads lets Google set bids to get the most leads for your budget (Help recommends a budget sized for about 10 leads per week and notes about two weeks for the model to learn). Target cost per lead (tCPL) is automated bidding around an average you or Google set. Max per lead is a manual ceiling—the most you would pay; Google says you may pay less. Weekly budget is a target: some weeks underspend, some overspend, but you do not exceed monthly max (weekly × 30.4 ÷ 7). After monthly max, the ad does not show unless you raise budget. Migrated specialized Performance Max pay-per-lead accounts in Google Ads use a daily average budget and Maximize Conversions; Google says manual max-per-lead and vertical-level tCPA are not supported. Message leads are typically priced lower than the matching phone lead. Google does not publish a US average plumber or HVAC CPL—do not use a blog’s number as yours.

Thumbtack Help: exact lead prices mean the price you set is what you pay unless a discount or promotion applies. You set a price per service; as you move the slider, Thumbtack shows an estimate of how many leads that service might produce. Weekly budget is the most you will spend across all services that week. Example Thumbtack publishes: $10 lead price and $90 weekly budget → 9 leads, then leads stop until next week unless you raise the budget. Minimum prices can change; prices near the minimum may increase automatically. There is still no public national CPL table.

To compare equivalent scope, do not match “$50 Google vs $50 Thumbtack” in the abstract. Match a calendar window, a spend cap, and the same CRM stages. Ask Google’s reports for charged vs credited leads by call/message/booking. Ask Thumbtack’s payment history for lead vs Opportunity charges and credits. Then compute booked-job CAC on both.

Vendor fact: neither Google nor Thumbtack publishes your close rate. BeltStack illustrative model—replace every number with your invoices.

Channel scorecard (run separately): spend, leads, qualified leads, booked estimates, booked jobs, revenue, gross profit, credits/refunds, cost per lead, cost per qualified lead, cost per booked job, CAC, revenue/spend, gross profit/spend. Cost per booked job = lead spend ÷ booked jobs. A channel with fewer, more expensive leads can win if it books more work.

Illustrative only: Channel A (LSA-shaped) 20 charged leads × $45 = $900 spend, 5 booked jobs → $180 per booked job. Channel B (Thumbtack-shaped) 12 leads × $35 = $420 spend, 3 booked jobs → $140 per booked job. If Channel A’s five jobs are $4,000 replacements and Channel B’s three are $180 diagnostics, A can still be the better business. Invert the tickets and B wins. Do not crown a winner from CPL.

Maximum affordable lead cost (illustrative framework, not a Google or Thumbtack bid): gross profit per completed job × lead-to-job close rate × the share of that contribution you will spend on acquisition. Example: $600 gross profit × 25% close × 30% acquisition share = $45. That $45 is not a recommended LSA bid or Thumbtack lead price. Substitute your average job, margin, close rate, and repeat-customer value. If your close rate is 10%, the same $600 and 30% share only supports $18.

These channels can run together. Tag source in CRM. Deduplicate the same customer who Googles you and also sends a Thumbtack request. Google Help notes about two weeks of bidding-model learning on Maximize Leads/tCPL—do not call a two-day sample a test. Use a window long enough to cover your sales cycle and at least a handful of booked jobs, not a generic 30-day slogan.
