2M+ websites
Every time you read a blog, check the news, or scroll through an app, you see them — banner ads, image ads, video thumbnails — all powered by the Google Display Network (GDN). With access to over 2 million websites, 650,000+ apps, and 90% of global internet users, Display Ads are one of the most powerful tools for reaching people before they even search for your product.
Unlike Search Ads (which target people actively searching), Display Ads put your brand in front of people while they browse. Think of it as a digital billboard that follows your ideal customer across the internet — but one that is targeted, measurable, and affordable.
Who Should Use Google Display Ads?
Display Ads are not for everyone. They shine brightest in specific scenarios. Here is who benefits the most:
B
Brand Awareness Campaigns
When your goal is visibility, not immediate clicks. Display Ads generate millions of impressions cheaply, putting your logo and message in front of your target audience repeatedly.
R
Remarketing / Retargeting
The #1 use case. Show ads to people who already visited your site but did not convert. Remarketing display ads have 10x higher CTR than standard display ads.
P
Product Launches
Launching something new? Display Ads let you blanket your target audience with visual creative before they even know to search for your product.
E
E-commerce Stores
Dynamic remarketing shows the exact products people viewed on your site. "That jacket you looked at? It is 20% off today." Incredibly effective.
A
App Promotion
Display Ads can run as app install ads across the Play Store, YouTube, and millions of apps. Google optimizes for installs automatically.
How the Google Display Network Works
The Google Display Network (GDN) is a collection of over 2 million websites, apps, and Google-owned properties (YouTube, Gmail) that have agreed to show Google ads. When you create a Display campaign, Google matches your ads to relevant websites based on your targeting settings.
Google Display Network Reach
90%
of internet users reached worldwide
Here is the process: You create a campaign in Google Ads, set your targeting (who should see your ads), upload your creative (images, headlines), and set a budget. Google then uses its algorithm to show your ads to the right people on the right websites at the right time. You only pay when someone clicks your ad (CPC) or per thousand impressions (CPM), depending on your bidding strategy.
Key insight: The GDN reaches approximately 90% of all internet users worldwide. No other single ad network comes close to this kind of reach. Whether your customer is reading the New York Times, checking Gmail, watching YouTube, or playing a mobile game — GDN can put your ad there.
Ad Formats & Sizes
Google Display Ads come in multiple formats and sizes. Understanding which sizes matter (and which you can skip) saves time and improves performance.
Common Display Ad Sizes (proportional)
Recommended: Responsive Display Ads
Google auto-adjusts your ad to fit any size and format. One ad, all placements.
The five most important sizes to know:
300 x 250
Medium Rectangle
Most common. Fits in sidebars and in-content.
728 x 90
Leaderboard
Top of page. High visibility, desktop-focused.
160 x 600
Wide Skyscraper
Tall sidebar ad. Good for brand messaging.
320 x 50
Mobile Leaderboard
Standard mobile banner. Huge volume.
300 x 600
Half Page
Premium placement. Higher engagement rates.
Pro tip: Skip uploading individual banner sizes. Use Responsive Display Ads instead. You provide images, logos, headlines, and descriptions — Google automatically assembles and resizes them to fit any ad slot. Responsive Display Ads get 50% more conversions on average compared to static banners, and they can appear in every size and format.
Targeting Options Deep Dive
Targeting is where Display Ads become powerful. Without proper targeting, you are showing banner ads to random people and burning money. With proper targeting, you are showing ads to people who are likely to care. Here is every targeting method available:
How Targeting Narrows Your Audience
All Internet Users (4.9B+)
Demographics (Age, Gender, Income)
Interests & Affinity Audiences
In-Market (Actively Researching)
Contextual + Placement Targeting
Your Ideal Customer
IM
Audience: In-Market
People actively researching and comparing products in your category. Google detects this through search behavior and site visits. Example: "In-market for running shoes" targets people who have been Googling running shoes, reading reviews, and visiting shoe sites in the past 7 days.
AF
Audience: Affinity
People with long-term interests and lifestyle patterns. Broader than in-market. Example: "Fitness Enthusiasts" targets people who regularly visit gym sites, read fitness blogs, and watch workout videos. Good for brand awareness at the top of the funnel.
CS
Audience: Custom Segments
Build your own audience by entering keywords, URLs, or apps your ideal customer uses. Example: Target people who search for "best CRM software" or visit competitor websites. This is incredibly powerful for niche targeting.
CK
Contextual: Topics & Keywords
Show ads on pages about specific topics or containing specific keywords. Example: Target pages about "home renovation" to show ads for power tools. Google scans page content in real-time and matches your ads to relevant pages.
PT
Placement Targeting
Handpick the exact websites, YouTube channels, or apps where you want your ads to appear. Maximum control but limited scale. Example: Only show ads on techcrunch.com, wired.com, and theverge.com.
RM
Remarketing Lists
Target people based on their past interactions with your business: site visitors, cart abandoners, past buyers, app users, YouTube viewers, or customer email lists. The highest-converting targeting method by far.
Strategy tip: Layer targeting methods for precision. Combine in-market audiences (people ready to buy) with contextual targeting (relevant page content) to reach the right person in the right context. This layering can reduce your cost per conversion by 30-50%.
Remarketing — The Secret Weapon
If you only run one type of Display campaign, make it remarketing. Here is why: on average, 97% of people who visit your website leave without taking action. They browsed, compared, got distracted, and left. Remarketing puts your ad back in front of those people as they browse other websites.
The Remarketing Loop
1
User Visits Your Site
Browses products, reads content
2
Leaves Without Buying
97% of visitors don't convert on first visit
3
Sees Your Ad on Other Sites
Display ads follow them across the web
4
Returns & Converts
Remarketing visitors are 70% more likely to convert
Repeat until conversion
Remarketing works because of the mere exposure effect — the psychological phenomenon where people develop a preference for things they see repeatedly. After seeing your ad 5-7 times across different websites, your brand feels familiar and trustworthy.
Standard Remarketing
Show generic ads to past site visitors. Simple and effective.
Dynamic Remarketing
Show the exact products or services a user viewed on your site. Personalized and high-converting.
Video Remarketing
Target people who interacted with your YouTube videos or channel.
Customer List Remarketing
Upload your email list and show ads to existing customers on Gmail, YouTube, and Search.
Important: Set a frequency cap (3-5 impressions per user per day) to avoid ad fatigue. Nobody wants to see the same ad 50 times. Overexposure annoys people and tanks your brand perception. Also set a membership duration — 30 days for most products, 90 days for high-consideration purchases like cars or enterprise software.
Creating Responsive Display Ads (Step-by-Step)
Responsive Display Ads (RDAs) are Google's recommended format. You provide the building blocks, and Google's machine learning assembles the best combination for each viewer and placement. Here is exactly how to create one:
How Responsive Display Ads Work
Banner Ad
Square Ad
Native Ad
Auto-fitted to any placement
1
Go to Google Ads > Campaigns > + New Campaign
Choose your campaign goal (Sales, Leads, Website Traffic, or Brand Awareness). Select "Display" as the campaign type. Set your daily budget and bidding strategy (Target CPA for conversions, Target CPM for impressions).
2
Set Your Targeting
Choose audience segments, topics, placements, or demographics. Start with in-market audiences for your product category. Add contextual keywords related to your offering. Exclude irrelevant placements (kids games, low-quality sites).
3
Upload Your Assets
Images: Upload up to 15 marketing images (1200x628 landscape + 1200x1200 square required). Logos: Up to 5 logos (1200x1200 square recommended). Headlines: Up to 5 short headlines (30 characters max). Long headline: 1 (90 characters). Descriptions: Up to 5 (90 characters each).
4
Add Final URL and Business Name
Enter your landing page URL. Make sure it matches your ad content (Google checks relevance). Add your business name exactly as you want it displayed. Optional: Add a call-to-action text like "Shop Now" or "Learn More".
5
Preview, Review, and Launch
Google shows you preview combinations across different formats and sizes. Check each preview carefully — text gets truncated if too long. Review your targeting one more time. Hit "Create Campaign" and wait 24-48 hours for approval and initial learning.
Key Metrics to Track
Display Ads have different KPIs than Search Ads. Do not judge Display performance by Search standards — a 0.35% CTR is normal for Display and does not mean your ads are failing. Here are the metrics that matter:
Impressions
10K-1M+
per day depending on budget
How many times your ad was shown. Display campaigns generate massive impressions because of the GDN's scale.
Reach
Unique users
who saw your ad
Unlike impressions, reach counts unique people. If one person sees your ad 5 times, that is 5 impressions but 1 reach.
CPM
$2-$10
cost per 1,000 impressions
The standard pricing model for awareness campaigns. Display CPMs are significantly cheaper than video or social CPMs.
View-Through Conv.
1-7 day
attribution window
Someone saw your ad, did not click, but later came to your site and converted. This is the "hidden value" of Display. Many advertisers miss this metric entirely.
CTR
0.35%
average across industries
Display CTR is much lower than Search (3.17%). This is normal. Display is about awareness, not clicks. Judge by conversions, not clicks.
Frequency
3-5x
ideal per user per day
How many times each person sees your ad. Too low and they forget you. Too high and they get annoyed. The sweet spot is 3-5.
Display Ads vs Search Ads — When to Use Which
This is the most common question advertisers ask. The answer is not "one is better" — they serve different purposes at different stages of the customer journey.
Display Ads vs Search Ads
AwarenessIntent
Display AdsSearch Ads
Display Ads
Great for brand awareness Use Display Ads when: You want to build brand awareness, reach people who do not know your product exists yet, retarget past website visitors, launch a new product or brand, or drive app installs. Display is a "push" channel — you push your message to potential customers.
Use Search Ads when: People are actively searching for what you sell, you need immediate conversions and leads, you have a limited budget (Search converts better per dollar), or your product solves a specific, searchable problem. Search is a "pull" channel — you capture existing demand.
Best strategy: Use both together. Run Search campaigns to capture high-intent traffic, and Display remarketing to bring back the 97% who leave without converting. This combination can increase your overall conversion rate by 30-50%. Search catches people ready to buy; Display brings back everyone else.
5 Common Display Ad Mistakes (and How to Fix Them)
Most Display campaigns fail not because Display does not work, but because advertisers make avoidable mistakes. Here are the five most common ones:
1
Not Excluding Irrelevant Placements
The Problem
Your ads appear on kids' game apps, parked domains, and low-quality sites that generate accidental clicks. You burn budget on bots and toddlers.
The Fix
Regularly check your "Where ads showed" report. Add irrelevant sites and apps to your placement exclusion list. Exclude the entire "Games" app category if you are targeting professionals. Exclude "anonymous" placements from the start.
2
Judging Display by Search Metrics
The Problem
You see a 0.3% CTR and think the campaign is failing. You pause it and miss the brand awareness and view-through conversions it was generating.
The Fix
Evaluate Display by impressions, reach, frequency, view-through conversions, and brand lift — not just CTR and direct conversions. Add view-through conversion columns to your Google Ads dashboard.
The Problem
One person sees your ad 87 times in a week. They go from not knowing you to actively hating your brand. Your budget is wasted showing ads to the same people over and over.
The Fix
Set a frequency cap of 3-5 impressions per user per day. In your campaign settings, go to "Additional Settings" > "Frequency Capping." Also set a maximum per week (15-20) and per month (45-60).
4
Using Only Static Banners
The Problem
You upload a single 300x250 image and wonder why your reach is low. You miss 90% of available ad placements because you do not have the right sizes.
The Fix
Always use Responsive Display Ads as your primary format. They automatically resize and reformat to fit any placement. Add static banners only as a supplement for placements where you want more creative control.
The Problem
You target "all ages, all genders, all interests" and wonder why your CPM is low but conversion rate is near zero. You are reaching millions of people who will never buy from you.
The Fix
Start narrow and expand. Begin with remarketing (warm audiences). Then add in-market audiences. Then layer in contextual targeting. Only go broad once you have conversion data to guide Google's algorithm.
Ready to Reach 90% of the Internet?
Google Display Ads are not about getting clicks — they are about building a brand that people recognize, trust, and eventually buy from. Start with remarketing, master your targeting, and watch your brand become the one people remember when they are ready to purchase.
Start with remarketing
