Originally published July 2018. Fully rewritten March 2026 to reflect the current advertising landscape and how businesses are using both channels today.

Most businesses don’t need to choose between social media advertising and search advertising — they need to understand when each one earns its keep. The difference comes down to intent: search catches people who already want what you sell, while social introduces you to people who might. Getting the balance right between those two things is where the real gains happen.

The Core Difference Hasn’t Changed

Back in 2018, when I first wrote this post, the fundamental difference between search and social advertising was simple. It still is.

Search advertising connects you with people who are actively looking for what you offer. They’ve typed something into Google — “plumber Auckland” or “accounting software for small business” — and your ad appears because it matches their intent.

Social media advertising works the other way around. You define the type of person most likely to buy from you — their age, interests, location, job title, behaviours — and your ad appears in their feed. They weren’t looking for you. You found them.

That distinction matters because it determines everything else: what you say in your ads, how much you pay per click, and how quickly you can expect results.

What’s Changed Since 2018

While the core principle is the same, the landscape around it has shifted significantly.

The platforms have multiplied

In 2018, “social media advertising” mostly meant Facebook. Today, Meta (Facebook and Instagram) still dominates with roughly 38% of global social ad revenue, but TikTok has grown into a serious advertising platform with $23 billion in ad revenue projected for 2025. LinkedIn has become the go-to for B2B advertising. YouTube Shorts competes for the same short-form video attention. Pinterest drives purchase intent in ways that blur the line between search and social.

For search, Google still commands the lion’s share, but Microsoft Advertising (Bing) has gained ground — particularly since integrating AI features into search results.

The line between search and social has blurred

This is probably the biggest shift. In 2018, search ads and social ads were clearly different things. Now, the boundaries are fuzzier.

Meta’s algorithm has gotten remarkably good at finding buyers without you having to define detailed audience criteria. Google’s Performance Max campaigns use audience signals alongside search intent. Retargeting means someone who clicked a search ad might see your follow-up message on Instagram. And social platforms like TikTok and Pinterest now have their own search advertising features.

The channels still work differently at their core, but they increasingly talk to each other.

The costs have diverged further

The cost gap between the two channels has widened. The average cost per click on Google Ads in 2025 sits around $5.26 USD across all industries. On Meta, it’s closer to $0.70–$1.11 depending on the campaign type.

But — and this is important — a cheaper click doesn’t automatically mean better value. Search clicks carry higher intent, which typically means higher conversion rates. You pay more per click, but each click is more likely to turn into a customer.

How to Think About the Split

Here’s how I tend to frame it for clients.

Start with demand

If people are already searching for what you offer on Google — and in decent numbers — that’s where your first dollar should go. You’re fulfilling existing demand. The intent is there. Your job is to show up with a compelling message and a good landing page.

This is the core of what we do with our Google Ads management — capture the demand that already exists and make sure every click counts.

Then build awareness

If your product or service is new, niche, or not something people typically search for, social advertising is your way in. You’re not answering a question someone already has — you’re planting one.

Social ads are also where you build the top of your funnel. Not everyone is ready to buy today, but the people who see your brand on Instagram or Facebook this month might search for you on Google next month. That’s a measurable pattern we see in client accounts regularly.

Use both when you can

The research backs this up. Advertisers running coordinated campaigns across three or more platforms outperform single-platform strategies by 25–35%. That’s not a small margin.

The two channels are complementary, not competing. Social creates the awareness that eventually drives the searches. Search captures the intent that social helped generate. When you track both properly, you can see the connection.

Different Channels, Different Messages

One thing that hasn’t changed: you need to talk differently on each platform.

On search, people are close to a decision. They’ve already identified a need. Your ad copy should be direct, benefit-focused, and answer the question “why you?” This is where strong messaging and clear differentiation win.

On social, people aren’t in buying mode. They’re scrolling through photos of their friends’ kids and watching cooking videos. Your ad needs to earn attention, not assume it. That means visual creative, relatable hooks, and content that gives value before asking for anything.

The biggest mistake I see is businesses running the same message on both channels. A Google Ad headline that says “Auckland’s Most Trusted Plumber — Call Now” works in search. On Instagram, it gets scrolled past without a second thought.

Where to Start if You’re New to This

If you’re advertising online for the first time, here’s a simple framework:

If people search for what you do — start with Google Ads. Capture that demand. It’s the fastest path to measurable results.

If people don’t know they need you yet — start with social. Define your ideal customer, craft a message that resonates, and build awareness. Meta (Facebook and Instagram) is still the most cost-effective starting point for most businesses.

If you’ve been running one channel for a while — add the other. The compound effect of search and social working together is real and measurable.

We help businesses across New Zealand figure out the right mix through our social media advertising and Google Ads management. If you’re not sure where your next dollar should go, that’s a conversation worth having.
