Google Demand Gen Campaigns: What They're For and How to Run Them

Demand Gen is Google's bid for the social-ads budget: visually-led placements across YouTube (including Shorts), Discover, and Gmail, aimed at people matching your customers before they search. It's neither Search (no query intent) nor classic display (much richer surfaces) — and it works only when treated as what it is: creative-driven demand creation.

Here's where Demand Gen fits and the playbook for running it.

Where it fits in the stack

Search captures demand that exists; PMax chases conversions across everything with limited steering; Demand Gen deliberately builds upper-and-mid-funnel demand with social-style creative on feed surfaces. Use it when search volume caps your category, when launching products nobody queries yet, or when you need a Google-side answer to Meta prospecting. Feed it audiences worth cloning — customer lists, converters, high-value segments — and expect it to make Search and brand queries grow, which is exactly the effect last-click reporting hides.

Creative requirements

This is a creative platform wearing Google Ads clothing: vertical video for Shorts-style placements, landscape and square for in-stream and Discover, strong static imagery for Gmail and feed cards — all with the social grammar: hook in the first second, captions on, product demonstrated, human presence. Supply full asset coverage so the system can match format to surface, refresh on fatigue like you would on Meta, and test angles (problem-led, proof-led, offer-led) rather than colorways. Recycled 16:9 TV cuts and static banners are how advertisers prove to themselves Demand Gen 'doesn't work'.

Audiences and measurement

Start with lookalikes built from your best first-party seeds and layer custom segments (search-behavior-based) for intent flavor; keep remarketing separate so prospecting stays honest. Bid toward conversions or value where volume allows, but evaluate at the campaign's actual job: incremental new users, assisted conversions, view-through patterns checked against holdout logic, brand-search lift during flights. Give it learning time and creative iterations before verdicts — demand creation compounds over weeks, and the accounts that win treat Demand Gen as a standing creative program, not a toggled experiment.

Common mistakes that quietly kill results

These come straight from audits we run every week. If any of them stings, you’re in good company — and the fix is usually faster than you think.

Letting the algorithm pick placements blind. Advantage+ and PMax help, but audit the placement and channel breakdown monthly. We routinely find 15%+ of PMax budget on display junk that converts at 0.1%.

Set-and-forget audience exclusions. Recent purchasers seeing your acquisition ads is pure waste. Sync your customer list and exclude buyers from prospecting — most accounts find 5-12% of spend leaking here.

Ignoring landing page speed. A 1-second delay costs roughly 7% of conversions. You're paying for the click either way — make it land on something that loads in under 2.5 seconds.

Changing three things at once. New audience + new creative + new bid strategy = you learn nothing. One meaningful change per campaign per week. Boring, but it's how you build an account you actually understand.

Quick checklist before you ship

• Budget split sanity-checked: 60-80% prospecting for growth accounts
• Search terms / placements reviewed in the last 7 days
• At least 3 new creative concepts in testing right now
• Frequency under 4 on retargeting in the last 30 days
• Purchasers excluded from prospecting audiences
• Tracking verified: a test conversion fired and matched in-platform
• One clear change per campaign this week, logged with a date

Frequently asked questions

Demand Gen vs Performance Max — which should I run?

Different jobs: PMax harvests conversions wherever they hide; Demand Gen builds demand with audience and creative control on feed surfaces. Mature accounts often run both with clean separation.

What budget does Demand Gen need to work?

Enough for the system to learn and creative to get a fair test across surfaces — think consistent daily spend over several weeks per audience-creative combination, scaled by your conversion volume.

Why does Demand Gen look expensive on last-click?

Because its conversions land elsewhere — on later searches and direct visits. Read assisted metrics, new-user rates, and brand-query lift before judging.
