Local service businesses -- HVAC, plumbing, roofing, electrical -- have relied on Dynamic Search Ads more heavily than almost any other vertical. DSA's crawl-based targeting was uniquely suited to catching "near me" and emergency-intent queries that manual keyword lists never fully covered. With DSA retiring in February 2027, this vertical faces a harder migration than most advertisers realize.
Why Home Services Leaned So Hard on DSA
A plumbing company's website has dozens of service-area pages: "emergency plumber [city]," "water heater repair [neighborhood]," "drain cleaning [zip code]." Building manual keyword lists for every geographic and service combination is impractical at any real scale. DSA solved this by crawling those pages and matching queries automatically -- no one had to enumerate the combinations by hand.
AI Max for Search replaces crawl-based matching with search themes: intent categories you define rather than pages you point the system at. For home services, this means the targeting logic that worked passively for years now needs active definition before the account can perform the same way.
The Negative Keyword Problem Gets Worse Before It Gets Better
Home services accounts have always fought a specific kind of query pollution: DIY searches ("how to fix a leaking faucet"), job-seeker searches ("plumber jobs near me"), and manufacturer-support searches ("Rheem water heater troubleshooting"). DSA's broad crawl-based matching occasionally served ads against these near-miss queries, quietly wasting spend.
AI Max's negative keyword handling is more reliable than DSA's ever was -- but only if the exclusion list is built deliberately before launch. Account-level negatives for "DIY," "jobs," "careers," "troubleshooting," "manual," and "how to" catch most of the pollution before it costs a click.

Migration Sequence for Multi-Location Service Businesses
Export your DSA auto-target performance report, sorted by conversions per service-area group. Home services accounts commonly run 10 to 40 auto-targets across service pages; a handful usually drive most of the conversions.
Convert each high-performing auto-target into a search theme built around service plus intent, not just service plus location. "Emergency water heater repair" performs differently as a theme than a flat "water heater repair."
Build the negative keyword list before launch, not after the first bad week of spend on DIY and job-seeker traffic.
Run AI Max in parallel with DSA for a full billing cycle in each service area before cutting DSA spend. Coverage varies more by geography than aggregate account numbers suggest, and a citywide average can hide a service area that is quietly losing volume.
Timing Around Seasonal Demand
Home services businesses that depend on Q4 and winter demand -- HVAC heating emergencies, roof damage from winter storms, frozen pipe repairs -- should not be mid-migration during their peak season. The AI Max learning period runs 2 to 4 weeks after launch, and a service business cannot afford degraded matching during a cold snap.

Budget Context for Smaller Local Operators
Many home services businesses run lean marketing budgets and outsource PPC management. Before adding AI Max migration work to an existing retainer, it is worth knowing what local SEO and PPC management should actually cost in 2026 -- and what red flags to watch for in pricing structures: https://yositeup.com/en-us/blog/local-seo-pricing-guide-2026
The Practical Bottom Line
DSA quietly did a lot of targeting work that home services businesses never had to think about. AI Max requires that thinking to happen upfront: search themes need explicit definition, negative keywords need deliberate exclusion, and auto-target performance needs auditing before the retirement date, not after it forces an automatic and unplanned migration.
