Google Display Network vs Search: Where Your Budget Actually Belongs

Let me tell you about an expensive mistake. Three years ago, I was managing ads for a fintech startup. They had $50K to spend on their first Google Ads campaign, and the previous agency had recommended going heavy on Display Network because "it's cheaper and you get more reach."

They spent $35K on Display, $15K on Search over three months. Results?

• Display: 2.8 million impressions, 8,400 clicks, 12 conversions. Cost per conversion: $2,917
• Search: 47,000 impressions, 1,230 clicks, 89 conversions. Cost per conversion: $168

The Display campaign looked amazing on paper - huge impression numbers, decent CTR for display standards. But it was absolutely hemorrhaging money on conversions that actually mattered.

This is the Display vs Search debate in a nutshell. Everyone wants the cheap clicks and massive reach of Display. But most businesses are way better off putting their money into Search first.

Let me break down when to use each, based on what I've actually seen work.

The Real Difference Between Display and Search

First, let's kill some myths.

Myth 1: "Display is for brand awareness, Search is for conversions."

Not quite. Display CAN drive conversions, and Search CAN build awareness. The real difference is intent.

Search ads show up when someone is actively looking for something. They type "best CRM for small business" into Google, and your ad appears. High intent. They're in shopping mode. Display ads show up while someone is doing something else - reading an article, checking Gmail, watching YouTube. You're interrupting them. Lower intent. They're in browsing mode.

This fundamental difference changes everything about how these campaigns perform and how you should use them.

Myth 2: "Display is always cheaper."

True, the CPC is lower. I typically see Display CPCs between $0.30-$1.50, while Search CPCs are $2-$15 depending on competition. But who cares about CPC if the conversion rate is terrible?

Here's real data from an e-commerce client I manage:

Display was "cheaper" on a per-click basis, but 3.7x more expensive on a per-conversion basis. This is what I see over and over again.

Myth 3: "You should split your budget 50/50."

No. For most businesses, Search should get 70-90% of your budget when you're starting out. Only after you've maxed out your profitable Search opportunities should you expand heavily into Display.

When Search Ads Destroy Display

Search campaigns perform better when:

1. You Have a Clear, Searchable Solution

If people are actively searching for what you sell, Search ads are a no-brainer.

Examples:

• Emergency services (plumber, locksmith, lawyer)
• Specific software categories (CRM, accounting software, email marketing tools)
• E-commerce products with search volume
• Local services

One of my clients runs a specialized B2B SaaS tool for construction project management. When we launched, I split $10K - $7K to Search, $3K to Display.

Search immediately crushed it: $198 cost per lead, 8.3% conversion rate. Display was a disaster: $847 cost per lead, 0.4% conversion rate.

Why? Because when a construction manager searches "construction project management software," they have INTENT. They're in the market. My Display ads showing up while they read industry news? Just noise.

2. You're Targeting Bottom-of-Funnel Keywords

Search lets you target specific buying intent. Keywords like:

• "buy [product]"
• "[product] pricing"
• "[your product] vs [competitor]"
• "best [solution] for [use case]"

These searches scream "I'm ready to buy." You can't target this level of intent with Display.

I ran a campaign for an AdsMAA push where we bid aggressively on terms like "Google Ads audit tool" and "PPC reporting software." Cost per signup was $43. Our Display remarketing for the same audience? $127 per signup.

Search captured people at the exact moment they were looking for a solution. That timing is worth paying for.

3. You Have Limited Budget

If you're working with under $5K/month, put it all in Search (with maybe 10% for Search remarketing). Don't spread yourself thin with Display.

Why? Search gives you immediate feedback. You can test keywords, ads, and landing pages quickly. You know within days what's working.

Display requires more volume and longer time horizons to optimize. You need to test audiences, creatives, placements. It's a slower learning curve, and when you only have $2K to work with, you can't afford slow learning.

When Display Network Wins

Okay, I've been hard on Display. But there ARE situations where it's the better choice:

1. Your Product Isn't Being Searched For Yet

Some products are so new or so niche that search volume doesn't exist yet.

I worked with a startup building an AI tool for podcast editing - super specific use case, barely any search volume for their exact solution. We tried Search, spent $4K, got 3 conversions.

Switched to Display targeting podcast creators based on website placements and YouTube channel interests. Spent $4K, got 41 conversions.

Display let us reach the RIGHT PEOPLE even though they weren't actively searching. We showed up on podcasting blogs, YouTube channels about content creation, Gmail for people subscribed to podcasting newsletters.

If you have a solution to a problem people don't know they have yet, Display can work better because you're creating awareness, not just capturing existing demand.

2. Remarketing Campaigns

This is where Display genuinely shines. Someone visits your site, doesn't convert, then sees your ads as they browse the web. This works.

I run remarketing for basically every client. Typical ROAS on Search remarketing: 300-500%. On Display remarketing: 250-400%. Still excellent.

Here's my standard remarketing setup:

Audience 1: Visited site, didn't convert (last 30 days)

• Bid: Medium
• Message: Remind them what they looked at, offer a nudge

Audience 2: Added to cart, didn't purchase (last 14 days)

• Bid: High
• Message: Show the exact product, maybe offer free shipping

Audience 3: Visited pricing page, didn't sign up (last 7 days)

• Bid: Highest
• Message: Address objections, show social proof

This sequence turned a 2.1% initial conversion rate into a 5.8% total conversion rate for an e-commerce client. The Display remarketing was responsible for that 3.7% lift.

3. Visual Products That Need to Be Seen

If your product is highly visual - fashion, home decor, food, travel - Display's image and video formats can outperform text-only Search ads.

An interior design client was spending $8K/month on Search with okay results. We shifted $3K to Display with gorgeous carousel ads showing before/after room transformations.

Display ROAS ended up 15% higher than Search for this particular client because the visual format let them show their work in a way that text ads couldn't compete with.

But note: this is the exception, not the rule. Most B2B and SaaS companies don't have this luxury.

The Hybrid Strategy That Actually Works

Here's what I recommend for most businesses with $10K+ monthly ad budget:

Phase 1: Search Foundation (Months 1-3)

Allocate 90% to Search, 10% to Search remarketing.

Focus on:

• High-intent keywords
• Branded terms
• Competitor terms (if conversion rate is acceptable)
• Remarketing to site visitors

Goal: Figure out your core profitable keywords and conversion funnel.

Phase 2: Expand and Remarket (Months 4-6)

Now you have data. Shift to 70% Search, 15% Search remarketing, 15% Display remarketing.

Add Display remarketing audiences based on your Search learner:

• People who clicked specific ad groups
• Visitors to high-intent landing pages
• Cart abandoners

Goal: Improve overall conversion rate by re-engaging warm traffic.

Phase 3: Scale with Display (Months 7+)

If you're maxing out profitable Search volume, shift to 60% Search, 20% Display remarketing, 20% Display prospecting.

Add Display prospecting:

• Similar audiences (to your converters)
• In-market audiences
• Custom intent audiences based on keywords

Goal: Find new customers who look like your existing ones.

This phased approach lets you build on what works rather than guessing with Display from day one.

How to Actually Set Up a Display Campaign That Doesn't Suck

If you do run Display, here's how to not waste money:

Step 1: Start with Remarketing Only

Seriously. Don't do cold Display prospecting until you've mastered Display remarketing. It's easier, cheaper, and converts better.

Set up audiences in Google Analytics for:

• All website visitors (last 30 days)
• Product/service page viewers
• Cart abandoners
• Pricing page viewers

Create separate ad groups for each. Different messages for different intent levels.

Step 2: Use Responsive Display Ads, But Give Them Good Assets

Google's responsive display ads use machine learning to auto-optimize. They work okay, but only if you give them quality inputs.

Upload:

• 5+ headlines (short and long)
• 3+ descriptions
• 5+ images (different formats: landscape, square, vertical)
• Your logo
• Videos if you have them

Don't just upload your Search ad copy. Display copy needs to be punchier and more visual-friendly.

Step 3: Exclude Placements Aggressively

This is where most Display budget gets wasted. Your ads show up on garbage websites with accidental clicks.

Go to Placements → Exclusions → Add excluded placements. I have a master list of 300+ excluded placements that I apply to every Display campaign.

Common ones to exclude:

• Mobile app placements (unless you specifically want them)
• Games and gaming sites (unless that's your audience)
• Parked domains
• Sites with suspicious traffic

Check your placements weekly. If a site is generating clicks but zero conversions, exclude it.

Step 4: Set Frequency Caps

Nobody wants to see your ad 47 times in one day. That's creepy and wasteful.

I typically set: 3 impressions per day, 10 impressions per week per user.

This spreads your budget across more people and reduces ad fatigue.

Step 5: Test Manual vs Automated Bidding

For Display, I've had mixed results with automated bidding. Sometimes Target CPA works great, sometimes it spirals out of control.

Start with manual CPC bidding (or Enhanced CPC) for the first few weeks until you have 30+ conversions. Then test automated bidding.

Watch it like a hawk for the first week. I've seen automated bidding increase CPCs by 200% with no improvement in conversion rate.

The Metrics That Actually Matter

Stop celebrating vanity metrics. Here's what to actually track:

For Search Campaigns:

Tier 1 Metrics (check daily):

• Cost per conversion
• Conversion rate
• ROAS (or ROI)

Tier 2 Metrics (check weekly):

• Quality Score
• Impression share
• Search terms (for negatives)

Don't care about:

• Impressions (unless impression share is low)
• Clicks (unless CTR is below 3-4%)

For Display Campaigns:

Tier 1 Metrics (check daily):

• Cost per conversion
• View-through conversions (but don't weight them equally to click conversions)
• ROAS

Tier 2 Metrics (check weekly):

• CTR (should be 0.3%+ for good campaigns)
• Placement performance
• Audience performance

Don't care about:

• Total impressions (meaningless without context)
• Reach (vanity metric)

I use AdsMAA to track all this automatically because manually pulling these reports for 15+ clients is impossible. The tool flags anomalies - like if Display CPA suddenly jumps 40% - so I can investigate fast. Check it out here if you're managing multiple accounts.

Budget Allocation: The Spreadsheet I Actually Use

Here's my exact framework for a $10K monthly budget:

Scenario 1: New Account, Proven Product Category

• Search (non-brand): $6,000
• Search (brand): $1,500
• Search remarketing: $1,500
• Display: $1,000 (testing only)

Scenario 2: Established Account, Search Maxed Out

• Search (non-brand): $4,000
• Search (brand): $1,000
• Search remarketing: $1,500
• Display remarketing: $2,000
• Display prospecting: $1,500

Scenario 3: Visual Product, Strong Brand

• Search (non-brand): $3,000
• Search (brand): $1,500
• Search remarketing: $1,000
• Display remarketing: $2,500
• Display prospecting: $2,000

The key is being flexible. If Search is crushing it and you haven't hit diminishing returns, keep feeding it budget. Don't force Display just because you think you "should" do it.

Common Display Mistakes That Burn Money

I've made all of these. Learn from my pain:

Mistake 1: Treating Display Like Search

Display needs different ad copy, different landing pages, different expectations. Don't just copy your Search ads into Display and wonder why performance sucks.

Display copy should be more emotional, more visual, more brand-focused. You're interrupting people, so you need to give them a reason to care.

Mistake 2: No Exclusions

Running Display with zero placement exclusions is like throwing cash into a fireplace. You WILL show up on junk sites with bot traffic.

Use AdsMAA or manually check placements weekly. Exclude anything with clicks but no conversions after spending $20+.

Mistake 3: Optimizing for Clicks

Display is optimized for conversions, not clicks. I don't care if an audience has a 1.8% CTR if it never converts.

I'd rather have 0.4% CTR with a 2% conversion rate than 1.5% CTR with a 0.1% conversion rate. Focus on cost per conversion, not cost per click.

Mistake 4: Ignoring View-Through Conversions

On the flip side, Display gets credit for view-through conversions - people who saw your ad, didn't click, but converted later.

These are real (though less valuable than click conversions). If you ignore them completely, you'll under-value Display.

I typically count view-through conversions at 30-40% of the value of a click conversion when evaluating Display performance.

The Verdict: Where Should YOUR Budget Go?

Here's my honest recommendation flowchart:

Start with Search if:

• You have under $5K/month budget
• People actively search for your solution
• You need immediate ROI
• You're in a competitive category with clear search volume

Add Display when:

• You've maxed out profitable Search volume
• You have 30+ conversions/month to optimize Display with
• You have strong visual assets
• You want to improve overall conversion rate with remarketing

Lead with Display if:

• Your product isn't being searched for yet
• You're in a highly visual category
• You have 6+ months to test and optimize
• You're focused on brand awareness first

For 80% of businesses reading this, the answer is: Put most of your money in Search. Use Display for remarketing. Only expand to Display prospecting once Search is humming.

Don't let anyone tell you that you NEED to run Display. You don't. I have clients spending $50K/month profitably on Search alone with zero Display.

Your Action Plan

If you're running both Search and Display right now:

Pull performance for the last 90 days

Calculate true cost per conversion for each (include view-through at a discount)

Calculate ROAS for each

If Display ROAS is under 200% and Search ROAS is over 300%, shift budget from Display to Search

Keep only Display remarketing running until you've maxed out Search

If you're starting fresh:

Launch with Search only, $7-8K if you have $10K budget

Build remarketing audiences for 30 days

Launch Search remarketing with $1-2K

After 60 days, if Search is profitable, test Display remarketing with $1-2K

Scale what works, cut what doesn't

Stop overthinking this. Search first, Display second. That's the playbook.

FAQ

Q: What about YouTube ads? Are those Display or different?

YouTube ads are technically part of the Display Network, but they behave differently. I consider them a third category. They work well for visual products, brand building, and remarketing. But they're even harder to convert cold traffic with than standard Display.

Q: Should I use Smart Display campaigns?

I've tested Smart Display extensively. Results are inconsistent. Sometimes they work great, sometimes they waste budget on junk traffic. If you use them, watch the first two weeks closely and be ready to kill them if CPA is 2x+ your target.

Q: Can Display work for B2B?

Yes, but it's tougher. B2B buying cycles are longer, so you need to be patient. Display remarketing works well for B2B. Cold Display prospecting is hit or miss. I've had better luck with LinkedIn ads for B2B prospecting than Google Display.

Q: What's a good Display CTR?

For remarketing: 0.5-1.5%. For prospecting: 0.2-0.6%. Anything under 0.15% consistently means your ads or targeting are off.

Bottom line: Search ads capture existing demand. Display ads create demand. Most businesses need to capture demand first before trying to create it. Don't skip steps.

Test this yourself. Run Search and Display in parallel for 90 days with equal budget. I bet Search crushes Display on cost per conversion for 9 out of 10 businesses reading this. And when it does, shift your budget accordingly.
