Google has extended the Reserve with Google Book button beyond Local Services Ads and Maps into standard Search campaigns and Performance Max. Any merchant whose Business Profile carries a working appointment link is now eligible for the feature by default. Nobody had to request it, configure it, or add tracking code for it to switch on.
Local search consultant Michel van Luijtelaar first documented the rollout in a LinkedIn post and on the GMBapi blog, including a screenshot of a live Book button sitting on a Search ad. As Search Engine Roundtable’s Barry Schwartz relayed it, van Luijtelaar summarized the shift this way: the booking flow “has moved from organic Local Search and Maps onto paid surfaces.”
Van Luijtelaar laid out several operational wrinkles that agencies running paid local campaigns will need to track:
- Eligibility is automatic, but influence on bidding is not. An advertiser must separately add the appointment conversion action inside campaign settings before Google’s systems start optimizing toward it.
- Clinics and other healthcare advertisers are excluded by policy. Google Ads still bars booking conversion goals in that vertical, so those accounts keep only the organic version of the button.
- Turning the feature off requires access to the advertising account itself. A Business Profile manager without Google Ads permissions has no way to disable it, which separates who controls the local listing from who controls whether it converts to paid.
The bigger risk here is financial rather than reputational, and it is the piece the source coverage underplays: agencies that treat appointment links as a one-time setup task, rather than an asset requiring the same audit discipline as a landing page, are the ones most exposed. A chain with dozens of locations typically accumulates appointment links added over years by different staff, and more than a few of them tend to point at a generic homepage instead of a location page. Under the old, organic-only Book button, a stray link like that cost a store a handful of missed clicks. Once Performance Max can route paid spend against the same link, a bad destination becomes a recurring line item, not a one-time missed opportunity.
Google widened the pool of Local Services Ads booking partners just days before this change surfaced, which suggests the company is deliberately pushing more Reserve with Google volume through paid inventory rather than leaving it confined to organic local results.
Any team managing Performance Max for a multi-location client should pull the full list of appointment action links this week, confirm each one resolves to a bookable page rather than a homepage, and check whether the appointment conversion action has actually been added to campaign settings. Left unchecked, a mismatched link no longer just underperforms; it now draws paid budget toward a page that cannot convert.
Search Engine Roundtable’s Barry Schwartz reported the expansion, citing analysis from local search consultant Michel van Luijtelaar.
