Google Ads Campaign Types: What Each One Is For — Picking the Right Inventory Before You Set Up or Audit an Account

Google Ads offers a fixed roster of campaign types, each tied to a different pool of inventory and a different amount of automation. Picking the wrong one wastes budget before a single auction runs. This page maps each type to what it accesses, how much control it leaves the advertiser, and which business goal it is meant to serve.

The Current Roster

- Search — text ads on Google search results, for people actively searching for what you offer — support.google.com/google-ads/answer/2567043 - Performance Max (PMax) — a goal-based type giving access to all Google Ads inventory (YouTube, Display, Search, Discover, Gmail, Maps) from a single campaign — support.google.com/google-ads/answer/10724817 - Shopping — product listings pulled from a Merchant Center feed, for retail sales — support.google.com/google-ads/answer/2567043 - Display — image/visual ads across millions of partner websites — support.google.com/google-ads/answer/2567043 - Demand Gen — captures engagement across YouTube (including Shorts), Discover, Gmail, Maps, and the Display Network, reaching up to 3 billion monthly active users — support.google.com/google-ads/answer/13695777 - Video — video ads on YouTube and other websites; objectives span awareness, consideration, and conversion — support.google.com/google-ads/answer/10197127 - App — finds new app users / drives in-app sales across Search, Play, YouTube, Discover, and 3+ million sites and apps — support.google.com/google-ads/answer/2567043

Not a campaign type — AI Max for Search

despite appearing alongside the others in some outlines, AI Max for Search is a *feature* (optimization layer) applied inside existing Search campaigns, not a standalone type. It adds improved search-term matching, text-customization of headlines/descriptions, and final-URL expansion, and it applies across all Search-campaign objectives — support.google.com/google-ads/answer/15910366. Google's 2025 internal data (non-Retail advertisers) reports advertisers who activate it typically see 14% more conversions or conversion value at similar CPA/ROAS — same source. Treat it as a setting to enable on Search, not a ninth type to choose between.

Intent-Based vs Discovery/Interest-Based

- Intent-based: Search and Shopping target people actively searching or with matched purchase intent — support.google.com/google-ads/answer/2567043. - Discovery/interest-based: Display reaches people while they browse partner sites; Demand Gen captures engagement on entertainment/discovery surfaces rather than search intent; Video reaches people during passive viewing — support.google.com/google-ads/answer/2567043, support.google.com/google-ads/answer/13695777, support.google.com/google-ads/answer/10197127.

This split is the first filter: if the goal is to catch demand that already exists, start from Search/Shopping; if the goal is to create demand or build reach, start from Demand Gen/Display/Video.

Performance Max: What It Subsumes and What It Doesn't

PMax pulls in YouTube, Display, Search, Discover, Gmail, and Maps inventory, uses Google AI across bidding, budget optimization, audiences, creatives, and attribution, and organizes creative into asset groups rather than ad groups — support.google.com/google-ads/answer/10724817.

It is explicitly a complement, not a replacement

Google states PMax is "designed to complement your keyword-based Search campaigns," does not eliminate existing campaign types, and does not replace Display, Video, or Shopping as distinct inventory access points — same source. Local campaigns also remain available and unchanged: Google's guidance is that advertisers who formerly used Local campaigns *can* continue optimizing to offline goals using PMax instead, as an alternative path — not that PMax formally replaces or retires Local campaigns — same source.

Prerequisites before turning it on

accurate conversion tracking and minimum historical conversion volume — same source. Each asset group needs high-quality text, image, and video assets so Google's AI has enough creative material to assemble ads from — same source; Google does not publish fixed numeric minimums for these assets, so treat "more high-quality variety per asset group" as the operating rule rather than a specific count. See What Does NOT Work: Performance Max Failure Modes for what happens when these prerequisites are skipped, and How to Launch Performance Max Without Cannibalizing Brand or Wasting Spend for the launch sequence that avoids eating your own Search brand traffic.

Funnel stage

awareness/top-of-funnel → Demand Gen, Video (reach objectives), or Display; consideration/mid-funnel → Display or Demand Gen with view-through/engagement goals; conversion/bottom-of-funnel → Search, Shopping, or PMax with conversion goals — support.google.com/google-ads/answer/15414676.

Creative assets required

Search needs minimal assets (text + optional sitelinks/extensions); PMax needs a wide variety of high-quality text, image, and video assets per asset group (no fixed numeric minimum published by Google — see note above); Video needs video; Demand Gen needs image and video, with carousel/interactive formats supported — support.google.com/google-ads/answer/2567043, support.google.com/google-ads/answer/10724817, support.google.com/google-ads/answer/10197127, support.google.com/google-ads/answer/13695777.

Control vs automation

Search offers the most manual control (keyword/negative-keyword selection, manual bidding entry point with low historical data); PMax is highly automated with AI-optimized bidding, placement, and creative combination; Demand Gen is automated on audience/creative but still lets you pick surfaces (YouTube vs Discover, etc.) — see Audience Signals: Why They're Hints Google Can Override, Not a Targeting Filter for how "signals" differ from hard targeting there; Display/Video sit in between via audience segments, placement exclusions, and bid adjustments — support.google.com/google-ads/answer/2567043, support.google.com/google-ads/answer/10724817, support.google.com/google-ads/answer/13695777.

Minimum data/budget

Google recommends a daily budget at least 10× the target CPA bid for Demand Gen — support.google.com/google-ads/answer/16797388. Smart Bidding strategies more broadly need enough conversion volume to exit the learning period without repeated resets — support.google.com/google-ads/answer/2472725; see Bidding Strategies: Manual, Smart Bidding, and When Each Applies — matching the strategy to the conversion data you actually have for the mechanics.

Campaign Type by Business Goal

Per Google's objective mapping (support.google.com/google-ads/answer/7450050):

- Sales → Search, Shopping, Performance Max - Leads → Search, Performance Max, Demand Gen - Website Traffic → Search, Display, Demand Gen, Video - App Promotion → App (exclusive to this type) - Awareness/Reach/YouTube Views → Display, Demand Gen, Video - Store Visits/Local → Performance Max, Display, Demand Gen, Video - AI Max for Search supports all Search objectives, since it is a layer on Search rather than a separate goal path.

Objective selection also drives which settings and feature recommendations Google Ads surfaces for the campaign — same source. Multiple goals rule: if a business has more than one goal (e.g., both leads and sales), Google's guidance is to build a separate campaign per goal rather than mixing objectives in one campaign — support.google.com/google-ads/answer/6238033.

Why this matters for the wiki's objective

setting up or auditing an account without burning budget starts with matching campaign type to goal and funnel stage correctly — the wrong type (e.g., PMax with no conversion history, or Display where Search intent was needed) is the single fastest way to spend without the signal to optimize against.
