5 digital advertising formats worth testing as a small business

Digital advertising means paying to place your message in front of a defined audience across online channels — including search engines, social platforms, display networks and video platforms. For small businesses, the five formats most worth testing are: Google Search Ads, Meta social ads, display advertising, video ads and retargeting campaigns. Each suits a different stage of the buying journey.

Key takeaways

• Google Search Ads capture demand that already exists — people actively searching for what you sell — making them one of the most commercially direct formats available.

• Meta Ads (Facebook and Instagram) let you build audiences by interest, behaviour and demographics, which is useful when demand for your product needs to be created rather than captured.

• Retargeting typically converts at a higher rate than cold audience advertising because it reaches people who have already shown interest in your business.

• Display advertising builds brand familiarity at low cost per impression, but should not be judged on direct response alone.

• Small businesses rarely need all five formats at once — starting with one or two and measuring properly will tell you more than spreading budget thinly across every channel.

What actually counts as digital advertising?

Digital advertising is any paid placement delivered through an internet-connected channel. That distinguishes it from organic digital marketing (SEO, social posts, content) where you earn visibility rather than buy it. The formats below all operate on an auction model: you bid for placement, set targeting criteria, and pay when users click, view or take another defined action.

The phrase "digital advertising" covers an enormous range of formats, costs and technical requirements. The five formats here are the ones a small business with a modest budget can realistically test, measure and optimise without a large in-house team. Revolve works with small and mid-sized UK businesses across all five, and the right starting point almost always depends on whether demand for your product already exists or needs to be built.

Which digital advertising formats are worth testing?

1. Google Search Ads

Search Ads appear at the top of Google results when someone types a query that matches your keywords. You pay per click. Because the user has signalled intent by searching, these ads sit at the bottom of the buying funnel — close to purchase.

Search Ads are the most sensible starting point for most small businesses selling a product or service people already know to search for. A plumber, an accountant or a software tool with an established category will find Search Ads commercially direct. If your product is genuinely new and nobody is searching for it yet, this format will not perform.

2. Meta Ads (Facebook and Instagram)

Meta's advertising platform lets you target by age, location, interests, job title and past behaviour. Ads appear in feeds, Stories and Reels. You can run image ads, carousel ads or short video formats, and pay per click or per thousand impressions.

Meta Ads work best for creating demand — reaching people who match the profile of your customer before they have started searching. They are particularly effective for consumer products, local businesses and any offer that benefits from visual presentation. The tracking setup matters enormously here: without accurate conversion events, you cannot tell which ads are generating real business outcomes rather than clicks.

3. Display advertising

Display ads are banner or image ads served across websites in Google's Display Network and other ad networks. You can target by topic, audience profile or specific websites. Cost per thousand impressions is typically low, but click-through rates are also low.

Display advertising earns its place as a brand-building format, not a direct-response one. It keeps your brand visible to a defined audience over time, which matters when your sales cycle is long or your category is competitive. Judging display purely on clicks will make it look like it's failing when it is doing a different job entirely.

4. Video advertising

Video ads run on YouTube, Meta and increasingly in programmatic networks. YouTube's skippable in-stream ads charge only when a viewer watches for at least 30 seconds or interacts — meaning you pay for genuine attention rather than passive impressions.

Video is the format with the highest persuasive ceiling because it can demonstrate a product, tell a story or build trust in a way static images cannot. The barrier for small businesses used to be production cost, but straightforward face-to-camera or screen-recorded formats perform well and cost little to produce. The stronger the first five seconds, the better the completion rate.

5. Retargeting campaigns

Retargeting shows ads to people who have already visited your website, engaged with your social profiles or interacted with previous ads. It works across Google, Meta and most programmatic platforms.

Because this audience has already expressed some interest, conversion rates are structurally higher than cold prospecting. A small business can run retargeting on a modest budget — even £5 to £10 per day — and see a measurable return, provided the website has enough traffic to build a meaningful retargeting pool.

How should a small business decide which format to start with?

Start with the format that matches where your customers are in their buying journey. If they are already searching, start with Search. If they don't know you exist yet, start with Meta.

What are the common mistakes small businesses make with digital advertising?

The most frequent problem is spreading a limited budget across too many formats at once. A £500 monthly budget split five ways produces data too thin to optimise from. Running one or two formats properly, with conversion tracking in place, will generate insight that a fragmented approach cannot.

The second common mistake is judging every format by the same metric. Display ads are not meant to drive clicks at the same rate as Search Ads. Setting the right success metric per format — impressions and brand recall for display, leads or purchases for Search — is what separates a fair test from a premature cancellation. A digital marketing agency can help set those baselines before you spend a pound.

Frequently asked questions

How much should a small business spend on digital advertising to see results? There is no universal minimum, but splitting budget below roughly £300 to £500 per month per channel usually produces data too sparse to draw conclusions from. A tighter budget spent on one channel will outperform the same budget spread across four.

Do small businesses need a landing page or can they send paid traffic to their homepage? A dedicated landing page nearly always outperforms a homepage for paid traffic because it removes distractions and matches the specific message of the ad. Sending paid clicks to a generic homepage increases the chance of a visitor leaving without taking action.

What is a good click-through rate for Google Search Ads? Click-through rates vary significantly by industry and keyword type. Branded keywords (your own business name) consistently produce the highest rates. For non-branded commercial keywords, a rate between 3% and 6% is a reasonable reference point, though this varies by sector and ad quality.

Can digital advertising work for a B2B small business, or is it only for consumer brands? Digital advertising works for B2B, but the formats and approach differ. LinkedIn Ads and Google Search Ads tend to perform better for B2B than Meta's consumer-oriented targeting. You can find a more detailed breakdown of this in Revolve's guide to paid advertising for B2B small businesses.

How long does it take for a digital advertising campaign to show reliable results? Search campaigns can produce data within days. Social and display campaigns typically need four to six weeks to exit the platform's learning phase and stabilise. Judging a campaign in its first two weeks is almost always premature.
