Search vs Social Media Advertising: Where Should Your First Dollar Go?

The short answer

Search captures demand. Social creates it. Someone typing "emergency plumber near me" has already decided to buy — search ads simply determine who gets the call. Nobody on Facebook is looking for a plumber; social ads have to make them want something.

That difference is the whole comparison. If people are already searching for what you sell, fund search first — it is the closest thing in advertising to picking up money that is already on the table. If nobody knows they need you yet, or nobody knows you exist, search will not save you, because you cannot capture demand that was never created.

The cost data, honestly presented

Here is where the conventional wisdom — "search is expensive, social is cheap" — turns out to be only half true.

Two things jump out.

First, the conversion rates are nearly identical — 8.18% against 7.72%. That surprises almost everyone. The advantage search enjoys is not that its clicks convert dramatically better; it is that its clicks cost much more, because those clicks are worth more.

Second, social leads are less than half the price. On a pure cost-per-lead basis, social wins outright and it is not close.

An important honesty note before anyone builds a budget on that table: these two figures come from different WordStream reports covering different periods (the search data runs April 2025 to March 2026; the Facebook data is the 2025 report). The gap is directional, not precise — and we say so on the references page rather than pretending to a false decimal. Where WordStream compares the two inside one report, it puts Facebook's lead-campaign click at $1.92 against Google's at $5.26.

So why would anyone pay more for a search lead?

Because a lead is not a customer, and not all leads are equal.

The person who searched told you what they want, when they want it. The person who filled in a Facebook form was scrolling, saw something appealing, and gave you an email address. Both are "leads." They close at very different rates, and the search lead is very often worth the extra $39.

This is the trap in optimising for cost per lead: the cheapest lead is not the cheapest customer. A $27 social lead that closes at 5% costs $540 per customer. A $67 search lead that closes at 25% costs $268. Neither of those numbers is in any benchmark table — they depend on your business, and you can only learn them by tracking what happens after the lead. If you are not tracking closes by source, you are not really comparing channels; you are comparing form fills.

What search is genuinely better at

• Intent. You are the answer to a question someone is already asking.
• Speed to revenue. Turn it on today, get calls tomorrow. No other channel does that.
• Lead quality, which usually justifies its price.
• Buying demand your brand has not earned. You can appear for "roof repair" without anyone having heard of you.

What search is genuinely worse at

• It is capped by demand. If only 200 people a month search for what you sell in your market, no budget can get you a 201st. This is the wall most successful search advertisers eventually hit — and the moment awareness channels stop being optional.
• Price. Cost per click is more than double what it was ten years ago ($5.42 against $2.32), driven by competition, not inflation alone.
• It cannot create want. For a new category, a new product, or an impulse purchase, there is nothing to capture.

What social is genuinely better at

• Creating demand in people who were not looking.
• Cheap volume and cheap learning — $0.70 clicks mean you can test five messages for the price of a handful of search clicks.
• Retargeting, which is where much of social's real return actually lives.
• Visual persuasion. Some things have to be shown, not searched for.

What social is genuinely worse at

• Intent, and therefore quality. You are interrupting.
• Creative fatigue. Performance decays and demands a constant supply of new assets. Search keywords do not fatigue.
• Volatility. Costs and targeting rules move under you.
• Taking credit it did not earn. Social measures itself well — well enough that it will happily claim conversions from people who already intended to buy.

The order to fund them in

For most local businesses, this is the sequence:

1. Capture existing demand first. Search, plus a Google Business Profile. If people are already looking for you and finding a competitor, nothing else you buy matters.
2. Add retargeting. The cheapest conversions on the internet are the people who already visited your site — display retargeting converts at about 1.42% against 0.34% for cold prospecting.
3. Then create demand. Once you have captured everyone who was already searching, growth must come from people who are not yet looking — social, and then the awareness channels above it.

The single most common budgeting mistake is doing this backwards: spending on awareness before there is anything set up to catch the response. The second most common is stopping at step one, plateauing, and concluding that "advertising stopped working" — when what actually happened is that you ran out of existing demand.

The right ratio depends on your goal, industry, market, and budget — a $2,000 plan and a $20,000 plan are not the same plan scaled.
