Two Very Different Channels Wearing the Same Google Ads Label
When clients tell me their “Google Ads are not working,” the first thing I check is whether they are running search campaigns or display campaigns — or both mixed together. These are fundamentally different advertising channels with different targeting logic, different CTR expectations, different conversion rates, and different best-use cases. Confusing them leads to bad decisions.
Search Ads: High Intent, Higher Cost, Higher Conversion
Google Search Ads appear when someone types a query into Google. The user is actively looking for something. This is called pull advertising — the user has signaled intent and you are presenting a solution. The CTR is higher (5-10% is normal), the CPC is higher, but so is the conversion rate. For service businesses, legal, medical, and high-ticket B2B, search ads are almost always the primary channel.
Search Ads Work Best When:
- Users actively search for your product or service by name or category
- Purchase or conversion intent is clear from the keyword
- Your market is local (search + location targeting is extremely efficient)
- You need trackable leads or sales on a defined budget
Display Ads: Low Intent, Low Cost, Low Direct Conversion
Google Display Network (GDN) reaches users on millions of third-party websites, apps, and YouTube. These users are not searching for anything — your banner ad interrupts whatever they are doing. This is push advertising. CTR is low (0.1-0.5% is typical and expected), conversion rate is much lower than search, but CPM (cost per thousand impressions) is cheap. Display ads buy awareness and retargeting at scale.
Display Ads Work Best When:
- You want to retarget past website visitors (this is where display ROI is highest)
- You are building brand awareness in a new market
- You have a strong visual brand and product (e-commerce, consumer goods)
- Your sales cycle is long and you need multiple touchpoints before conversion
The Retargeting Sweet Spot: Display That Actually Converts
The best use of display advertising for most small businesses is retargeting: showing ads to people who visited your website but did not convert. Retargeting audiences have already demonstrated intent by visiting your site. Display retargeting CTR (0.5-1.5%) and conversion rate are significantly higher than cold display audiences. If your site gets 500+ visitors per month, retargeting should be active.
Performance Max: The Hybrid Both Channels Live In Now
Google pushed Performance Max (PMax) campaigns heavily from 2022 onward. PMax runs across search, display, YouTube, Gmail, and Maps from a single campaign. It can work well for e-commerce and businesses with solid conversion tracking. For most local service businesses, I still recommend dedicated search campaigns over PMax for control and transparency.

How to Run Both Without Confusing the Data
- Keep search and display in completely separate campaigns — never mix them
- Use different bid strategies: Target CPA or Max Conversions for search, Target CPM or Maximize Clicks for awareness display
- Judge display campaigns on brand lift and retargeting volume, not direct conversion rate
- Set frequency caps on display to prevent ad fatigue (3-5 impressions per user per day is a reasonable starting point)
Frequently Asked Questions
What is the difference between display ads and search ads?
Search ads appear on Google results pages when users actively search for keywords. Display ads appear on websites and apps as banner or image ads.
Which has a higher conversion rate: display or search ads?
Search ads typically have higher conversion rates because they reach users with active purchase intent.
Are display ads worth running for small businesses?
Display ads are worth running for retargeting and awareness. As a standalone lead-gen strategy on small budgets, search ads generally outperform.
What is a good CTR for display ads?
A good CTR for display ads is 0.1-0.5%. Display CTR is much lower than search CTR by design.
Can I run display and search ads at the same time?
Yes. Running both in separate campaigns is recommended to track performance independently and apply different bid strategies.
What budget do I need to start Google Display Ads?
You can start with as little as $10-15/day. Retargeting campaigns need at least 500 website visitors per month to build a meaningful audience.
