Campaign Types & Objectives

Search vs Display Campaigns: Intent vs Reach

In short: Search campaigns answer demand: someone types a query and you pay for the click. Display campaigns interrupt, appearing on publisher sites and apps to audiences you choose, bought cheaply on impressions or clicks. Search converts at a far higher rate; Display costs far less per impression and earns its place in retargeting and reach.

Display Campaigns

Image and responsive ads served across the Google Display Network's publisher sites and apps, bought mostly on impressions or inexpensive clicks.

You pick audiences, topics, or placements, upload images or let responsive display ads assemble them, and Google buys inventory across millions of sites. Advertisers use it for cheap reach and retargeting rather than demand capture. The frequent error is leaving optimized targeting and mobile app inventory unchecked, so budget drains into low-quality placements, then judging the whole channel on last-click conversions.

Search Campaigns

Text ads matched to the words a person types into Google, billed per click and shown at the moment of stated intent.

You build ad groups around keyword themes, write responsive search ads, and set a bidding strategy; Google matches queries to your keywords and runs an auction on each search. Advertisers use them to capture existing demand rather than create it. The usual mistake is ignoring the search terms report, so broad match quietly spends budget on queries you would never have bought.

What actually separates them.

01

A Search ad is served because of what someone wrote, while a Display ad is served because of who Google thinks they are or what page they are on.

02

Display inventory is effectively unlimited, so a Display campaign will spend whatever budget you give it, whereas Search spend is capped by real query volume.

03

Display carries placement risk from mobile apps and low-quality sites that Search does not, so exclusions are ongoing maintenance rather than a one-time setup.

04

Last-click reporting flatters Search and understates Display, because most of Display's contribution shows up as view-through or assisted.

Which one should you use?

Use Display Campaigns when

  • You are retargeting people who already visited, where the ad works as a reminder rather than a pitch.
  • You need cheap incremental reach around a launch, an event, or a seasonal window.
  • Search volume in your category is small because people do not yet know the product exists.
  • You have image creative strong enough to carry a message without a query for context.

Use Search Campaigns when

  • People already search for the problem or the product by name.
  • Budget is limited and every dollar should go to the highest-intent traffic available.
  • The offer needs qualification, and the click should land on a page that answers a specific query.
  • You need results that are legible in last-click reporting, for instance to prove paid media works internally.

Common questions.

Should I turn on Display expansion inside a Search campaign?

Usually not. It blends two very different inventories under one budget and one report, and cheap Display clicks can absorb the budget while appearing in Search performance. Run Display as its own campaign with its own budget, targeting, and exclusions, so each channel can be judged and managed on its own terms.

Why is my Display conversion rate so much lower?

Because nobody on Display asked for your product. They were reading an article or using an app when the ad appeared, so conversion rate is expected to be a fraction of Search. Judge Display on cost per incremental outcome, on assisted and view-through contribution, or on a holdout test, rather than on last-click conversion rate.

Or stop choosing between them.
