Two different mechanisms
Paid advertising is a rental. You are bidding for a position, you get it the moment the campaign goes live, and it disappears the moment the budget stops. Local SEO is closer to ownership: the pages, the profile and the reviews you build keep working after any given month's effort ends, but building them takes real time before they produce anything.
Local Services Ads, specifically
For a service business, the relevant paid product is usually Local Services Ads rather than standard search ads. Google's own help pages describe it as pay-per-lead, not pay-per-click: you set an average weekly budget, and you are only charged for a lead Google determines is valid, such as a text, email, voicemail or call from a real customer, an answered call, a returned missed call, or a booking request. Leads later found to be low quality can be credited back automatically.

Running Local Services Ads also requires passing a screening and verification process first, marked with a single "Google Verified" badge once you clear it. Depending on category and location, that process can include license checks, a certificate of insurance, and background checks on the business, the owner and field staff, so it is not a specific quote you can get without qualifying.

What each actually costs
Standard Google Search ads for the home services category averaged 8.33 US dollars per click in 2026 industry benchmark data, and that is a cost per click, not a cost per booked job; a home-service cost per lead typically runs several times higher once you account for clicks that do not convert. Local SEO has no per-click charge at all, but it is not free: it is either staff time or a monthly service fee, the same shape as the flat plan described on this site.

A plain decision table
- Need the phone to ring this week: paid ads, most likely Local Services Ads for a service business, since it is built for exactly that.
- Running a short seasonal push, like the first cold snap or right after a storm: ads, since SEO cannot be switched on fast enough to catch a two-week spike.
- Have a few months and want the ongoing cost to come down over time: local SEO, since a ranking you earn keeps paying without a per-lead charge.
- Building the business for the next three to five years, not just this quarter: SEO, since a paid position disappears the day the budget stops and an earned one mostly does not.
- Have the budget for both: run ads for the calls this month while SEO is still climbing, then let more of the budget lean on SEO once it starts producing.
