Google Ads Search vs Performance Max for service brands

Every Google rep we’ve ever spoken to wants you to move budget into Performance Max. Some of that is genuine — PMax has gotten better. Most of it is because PMax is opaque, sticky, and protects Google’s margin. For founder-led service businesses in India, the answer almost always sits between the two, and the split matters more than the campaign type.

Search still owns high-intent keywords

If someone in Bandra types "interior designer for 2 BHK", that is the most valuable click you will ever buy. Search lets you bid on it directly, write the exact headline, and send the click to the exact landing page. PMax can technically serve a search ad to that query, but you get no control over which queries you show on, what creative shows up, or what the bid was. For services with a narrow keyword universe, Search is still where you start.

PMax shines when your asset library is deep

PMax feeds on creative. If you have 10 product photos, two videos, a logo, and three headlines, it’s starving. If you have 60 images, 8 videos, 15 headlines and 30 descriptions, it cooks. Founder-led service brands rarely have that asset depth on day one, which is why PMax disappoints when it’s switched on too early.

• Minimum to launch. 5 videos, 20 images, 15 headlines, 4 descriptions.
• Refresh cadence. 30% of assets swapped every six weeks.
• Audience signals. Customer match list, website visitors, purchase intent.

The hidden Search-cannibal problem

PMax loves to serve on your brand keyword and steal credit from Search. We’ve seen accounts where 40% of PMax conversions were people who searched the brand name. The fix is a brand exclusion list at the account level — a feature Google finally rolled out properly — plus a dedicated Brand Search campaign that bids low and protects the SERP. Without this, PMax will look like a hero while doing nothing for new demand.

For service brands, lead quality beats lead volume

PMax optimises towards the conversion event you give it. If that event is "form submitted", you will get 200 form submits a month, 70% of which are junk. The fix is offline conversion import — push qualified leads back from your CRM into Google with a value attached. Within four weeks PMax pivots and starts finding people who look like your closed-won deals, not your form-fillers. This is the single highest-leverage thing most service businesses ignore.

Our default split for an Indian service brand

Branded Search at 10% of budget, non-branded Search at 50%, PMax at 30%, YouTube or Demand Gen at 10%. We start there and adjust based on the lead-quality data after week six. For brands with zero asset library, we push PMax to 0% and run pure Search until we’ve shot enough creative to feed the beast. That usually takes a month and saves 1-2L of wasted spend.

The reporting trap

PMax reports look great because Google attributes conversions generously. We pull the actual data through a GA4 + CRM join, compare last-non-direct attribution to PMax’s claimed conversions, and almost always find a 25-40% gap. Founders who only look at the Google Ads UI think PMax is their best channel. It usually isn’t. It’s the channel with the most favourable reporting.

How we help at The Nerdish Mic

We build and run Google Ads accounts for founder-led service businesses across India — real estate, interior design, clinics, B2B SaaS, professional services. We’ll audit what’s running today, rebuild the structure where needed, and wire up the offline conversion loop so PMax actually finds you customers, not form-fillers. If your Search and PMax split was decided by a Google rep, it’s probably worth a second opinion.
