Paid search or paid social: which should you start with?

Paid search and paid social are both advertising, and otherwise almost opposites. Getting the choice right matters most when the budget is small, because splitting a modest budget across both usually means neither gets enough to work.

The difference in one sentence each

Paid search captures demand. Someone searches “emergency plumber near me” and your ad appears. They’ve already decided they need the thing; the only question is who provides it. The main platforms are Google Ads and Microsoft Advertising.

Paid social creates demand. Someone is scrolling and your ad interrupts them with something they weren’t looking for. Nobody opens Instagram to buy industrial flooring. The main platforms are Meta (Facebook and Instagram), TikTok, LinkedIn and Pinterest.

Everything else follows. Search needs little persuasion but is limited by how many people search. Social can reach almost anyone but has to do all the persuading itself.

Start with search when

• People search for what you sell. Established categories with named demand: plumbers, accountants, CRM software, replacement windows.
• The need is urgent. A broken boiler, a locked door, a legal deadline.
• You sell locally. Local searches show strong intent.
• Your product is hard to show. Professional services are difficult to make visually striking, and on search they don’t need to be.
• You need a quick answer. Search shows within weeks whether people will enquire.

The limits are volume and price. If only a few dozen people a month search for your service, a bigger budget can’t buy more searches. And competitive commercial terms are expensive because every bidder wants them. How much Google Ads costs shows how to check both before you commit.

Start with social when

• Nobody is searching yet. New categories, new products, anything people don’t know exists.
• The product is visual. Food, clothing, interiors, travel — anything with an obvious before and after.
• You can describe the buyer precisely. An interest, a job title, a life stage.
• The purchase is impulsive or low risk. Lower prices survive being sold to someone who wasn’t looking.
• You can make ads. This is the real gate.

On social, the ad is the campaign

In paid search, the choice of searches, the bids and the landing page do most of the work, and the ad is a few lines of text. In paid social, the creative — the image or video and its message — does most of the work. The same audience and budget can produce very different results depending on what people see.

People tire of an ad quickly, so paid social needs a steady supply of new creative. If you have no photos or video and no way to make any, paid social will struggle whoever manages it. Fix that first, or start with search.

What each needs before you spend

Paid search needs:

• Real search demand for terms that signal buying intent
• A landing page that answers the search, not just your homepage
• Conversion tracking that works, including phone calls if customers ring
• Enough budget to appear consistently for your main searches

Paid social needs:

• Several versions of the ad, and a way to keep making more
• A clear idea of who the buyer is
• An offer strong enough to interrupt someone
• Patience through a testing phase that will look like waste

Both need working measurement before the first click. What to measure in your marketing explains how to set it up.

Measurement is harder than it used to be

Both channels are measured less completely than a few years ago. Visitors who decline cookies may not be tracked, browsers limit tracking across sites, and platforms increasingly estimate what they can’t see. If you advertise to people in the UK, Ireland or elsewhere in Europe, Google requires consent signals for its measurement and personalisation features — its consent mode requirements (opens in a new tab) explain how. Rules elsewhere differ by country and, in the US, by state.

In practice, platform-reported results and your own analytics will disagree, and neither is simply wrong. Paid social tends to look worse than it is in click-based reports, because people often see an ad, then buy days later without clicking it.

Don’t settle it by trusting whichever number is highest. Watch total enquiries and sales against total spend over a meaningful period, and treat channel-level figures as a guide.

If the budget is small

Pick one. Split across two channels, a small budget often gives neither enough data to show what’s working, and you end up with two inconclusive experiments.

The default: if people search for what you sell, start with search, because it’s the quicker way to find out whether paid advertising works for you at all. If they don’t, start with social, and budget for creative as part of the cost. Move to the second channel once the first is clearly working or clearly not.
