Short answer: paid search shows your ad to people who are already looking for something like what you sell. Paid social shows your ad to people who match an audience you define but weren't looking. Search tends to suit businesses whose customers search when they need you; social tends to suit businesses that need to be discovered. Many small businesses are better off with one, done properly, than both done thinly.
What each one is
Paid search. Google describes a Search campaign as a way to reach people on the Google Search Network, where "your ads can appear" near search results when people search for terms that match your keywords. The person has typed what they want.
Paid social. Meta describes its approach as letting advertisers "decide who sees your ad and where," narrowing an audience by location, age, gender and interests. The person was scrolling, and your ad interrupted that.
That difference, intent versus interruption, drives everything else.
What it means in practice
| Paid search | Paid social | |
|---|---|---|
| Who sees it | People who searched for terms matching your keywords | People matching the audience you set, whatever they were doing |
| Best for | Needs people already have: "emergency plumber", "wedding venue near me" | Things people didn't know they wanted, visual products, building awareness |
| Strength | Catches existing demand at the moment of need | Creates demand and reaches people who'd never search for you |
| Common weakness | You can only reach people who search; volume may be small in a small market | Many viewers aren't ready to act, so enquiries can cost more |
| What needs most care | Keywords, negative keywords, landing page match | Creative, audience, the offer |
On the search side, negative keywords matter: Google says they let you "exclude search terms from your campaigns," but note they "won't match to close variants or other expansions," so they need maintenance. On the social side, Meta's own guidance is to start broad, and it says that once an ad runs, "our system will learn who is engaging with it." Both platforms reward patience and clean tracking.
How to choose
Ask three questions.
1. Do your customers search for you when they need you?
If someone with a burst pipe or a legal problem goes straight to Google, search catches them at the right moment. If your product is something people only buy when they see it, such as a boutique gift, social reaches them where search can't.
2. Is your goal an enquiry now, or to be known?
Short-term enquiries lean toward search. Familiarity in a market with long decision cycles leans toward social, with retargeting and email to follow up.
3. Is the search volume big enough?
If few people in your area search for what you sell, a search campaign can't spend its budget usefully. Social can work harder there, but expect it to take more testing.
Common small-business patterns
- Urgent local services (plumbing, locksmith, clinic): search first.
- Visual, considered or impulse purchases (jewellery, food, events): social first, with search for branded and "near me" terms once demand exists.
- High-value B2B services: often search plus a small social budget for retargeting, with LinkedIn considered separately.
- A new brand nobody searches for yet: social and organic content build the demand search will later catch.
When to use neither yet
If your website doesn't load quickly or doesn't make the next step obvious, or you can't count enquiries, fix those first. Paying to send people to a page that doesn't convert is the most expensive way to find out.

What this doesn't tell you
We can't tell you your cost per enquiry on either channel; it varies by market, offer and competition, and that's why a test beats an assumption. Run one channel for long enough to learn, measure by enquiries rather than clicks, and add the second only when the first is predictable.
Common questions
Can I run both?
Yes, once one is working and you can measure both. Splitting a small budget across two channels from the start often means neither gets enough data.
Which is cheaper?
There's no universal answer. Cost depends on your market, competition, offer and page. Compare by cost per enquiry, not cost per click.
Do I need a website for either?
In practice, yes. Both send people somewhere, and that place determines whether the click becomes an enquiry.
