One captures demand that already exists. The other creates demand that does not.
That single distinction answers most of this question, and it is more useful than any feature comparison.
Search puts you in front of someone who has already decided they want something and is looking for who provides it. The intent is pre-existing; you are competing for a decision already in motion.
Social puts you in front of someone who was not thinking about you at all. You have to create the want, which is harder — and it is the only way to reach people who do not yet know your category solves their problem.
Start with search when...
- People actively search for what you do. Emergency plumbing, lawyers, dentists, "restaurant near me," "med spa Brickell." If there is a query, capture it first.
- The purchase is urgent or scheduled. Someone with a broken air conditioner is not being persuaded; they are choosing.
- You are local with a clear service. Local search intent is the highest-converting traffic most small businesses will ever buy.
- Budgets are small. A modest search budget against high-intent queries usually beats the same money spent trying to create demand.
Start with social when...
- Nobody is searching for it. New categories, impulse products, things people did not know existed.
- The product is visual. Food, fashion, interiors, aesthetics, venues, travel.
- Search is prohibitively expensive. In some categories a single click costs more than the customer is worth.
- You need volume and scale. Search is capped by how many people are looking. Social is capped by budget.
- You have good creative. This is the prerequisite, not a bonus.
The honest cost comparison
Search costs more per click and converts at a higher rate, because the intent is already there. Social costs less per click and converts lower, because you are interrupting rather than answering.
What matters is not the click price but the cost per actual customer, and that varies enormously by category. In competitive professional services, a search click can run to tens of dollars and still be the cheapest customer available. For a visual consumer product, social will usually win outright.
The practical answer: for a first $5,000, most local service businesses should put roughly $3,500 into search and $1,500 into social retargeting. Most visual consumer brands should invert it.
Once you can afford both
They work considerably better together than either does alone:
- Social creates awareness. People encounter the brand.
- Search captures the resulting intent. When they later search your name or category, you are there.
- Retargeting closes. Across both, at low cost, against people who already engaged.
A reliable signal that social is working: branded search volume rises. People saw the ad, remembered the name, and searched it later. That conversion will be attributed to search, which is one of several reasons to distrust attribution as truth.
Do not skip these
- Branded search. Cheap, high-converting, and protects against competitors bidding on your name. Some businesses resist paying for traffic they think they would get free — usually until a competitor takes it.
- Google Business Profile. Free, and for local businesses it frequently outperforms paid search. Fix it before you spend anything.
- Landing pages that match the ad. The cheapest performance improvement available in either channel. Detail here.
- Conversion tracking. Without it you are optimising on guesses in both platforms.
A sane first ninety days
- Month one: tracking installed and verified, Google Business Profile fixed, branded search live, one high-intent search campaign, one retargeting campaign.
- Month two: add non-branded search on your best two or three query groups; begin social prospecting with three to four creative variations.
- Month three: cut what is not working, double what is, and start the creative testing loop properly — framework here.
The bottom line
If people are already searching for what you do, buy that first. If they are not, you have to create the want, and social is where that happens. Then run both, expect the attribution to be messy, and judge on total revenue against total spend.
