Why choosing the right platform matters
Picking the best online advertising for small business is not about following trends or copying competitors. It is about understanding where your customers spend their time and what stage of the buying journey you want to intercept them at. Each platform has distinct strengths, cost structures, and audience profiles. Choosing the wrong one wastes budget. Choosing the right one generates profitable growth.
This comparison covers the five major platforms available to UK small businesses: Google Ads, Facebook, Instagram, LinkedIn, and Microsoft (Bing) Ads. For each, we cover who it suits best, typical costs, and the strengths and weaknesses you should know about before committing your budget.
Google Ads: capturing active demand
Google Ads remains the best online advertising for small business when your goal is to capture people who are actively searching for what you sell. Search campaigns place your ad at the top of Google results for specific keywords. The intent behind these clicks is high, which is why conversion rates from Google Search ads typically outperform other platforms.
Beyond Search, the platform offers Shopping campaigns for ecommerce, Display campaigns for brand awareness across partner websites, YouTube video ads, and Performance Max campaigns that use machine learning to place ads across all Google properties. This range makes Google Ads the most versatile advertising platform available.
Typical costs for UK small businesses range from one to five pounds per click for most industries, though competitive sectors like legal, finance, and insurance can see clicks above ten pounds. Monthly management is essential because the platform rewards well-optimised accounts with lower costs and better ad positions.
Best for: Service businesses, local businesses, ecommerce, lead generation. Any business where customers start their journey with a Google search.
Facebook ads: reaching your ideal audience
Facebook advertising lets you target people based on demographics, interests, behaviours, and location rather than search intent. This makes it a powerful tool for generating demand rather than just capturing it. You can put your business in front of people who match your ideal customer profile, even if they were not actively looking for you.
The platform excels at visual storytelling. Carousel ads, video ads, and lead generation forms all perform well for businesses with compelling creative assets. Lookalike audiences allow you to find new customers who resemble your best existing ones, which is remarkably effective when you have enough customer data to work with.
Cost per click on Facebook is generally lower than Google Ads, often between thirty pence and two pounds for UK businesses. However, the intent behind those clicks is typically lower, so conversion rates can be lower too. The best Facebook advertisers understand this and build campaigns around lead nurturing rather than expecting immediate sales.
Best for: Consumer products, local services, event promotion, lead generation for businesses with a strong visual story to tell.
Instagram ads: visual-first advertising
Instagram advertising runs through the same platform as Facebook (Meta Ads Manager) but reaches a distinct audience. The platform skews younger and is heavily visual. If your product or service photographs well, Instagram can deliver excellent results at reasonable costs.
Stories ads, Reels ads, and feed posts all offer different creative formats. For businesses in fashion, food, fitness, home interiors, beauty, and similar visual sectors, Instagram often outperforms Facebook in engagement and cost per lead. The platform’s shopping features also make it increasingly valuable for ecommerce businesses.
The key limitation is creative demand. Instagram users expect high-quality visuals. Stock photos and text-heavy images perform poorly. Businesses that invest in authentic, professional-quality content see the strongest returns.
Best for: Visually appealing products, lifestyle brands, hospitality, food and drink, fitness, and any business targeting audiences under 45.
LinkedIn ads: B2B targeting precision
LinkedIn is the best online advertising platform for B2B businesses targeting professionals and decision-makers. No other platform lets you target by job title, seniority, company size, industry, and specific companies with the same precision. If you sell to other businesses, LinkedIn puts your message in front of the exact people who sign off on purchases.
The trade-off is cost. LinkedIn advertising is significantly more expensive than other platforms, with clicks typically costing five to fifteen pounds in the UK. However, if you are selling high-value B2B services where a single client is worth thousands, the maths can work very well. The leads are higher quality because the targeting is so precise.
Sponsored Content (feed ads), Message Ads (InMail), and Lead Gen Forms are the most popular formats. Lead Gen Forms are particularly effective because they pre-fill with the user’s LinkedIn profile data, reducing friction and increasing conversion rates.
Best for: B2B service providers, consultancies, recruitment, SaaS companies, professional services targeting senior decision-makers.
Microsoft (Bing) ads: the overlooked opportunity
Microsoft Advertising (formerly Bing Ads) is consistently overlooked by small businesses, which creates an opportunity. Bing powers search results on Microsoft Edge, Yahoo, and various partner sites. It reaches roughly 15-20% of UK desktop search traffic, and its users tend to skew slightly older and more affluent.
The biggest advantage is competition. Fewer advertisers means lower cost per click, often 20-40% less than equivalent Google Ads campaigns. For businesses already running profitable Google Ads campaigns, importing those campaigns into Bing is straightforward and typically generates additional leads at a lower cost per acquisition.
The platform offers Search, Shopping, and Audience campaigns that mirror Google’s functionality. While the reach is smaller, the efficiency often makes up for it. If your target audience includes professionals who use Microsoft products at work, Bing is particularly worthwhile.
Best for: Any business running Google Ads that wants incremental volume at lower cost. Particularly effective for B2B and professional services.
How to decide which platform to use
Start by answering two questions. First, are your customers actively searching for what you offer? If yes, Google Ads should be your priority. Second, can you clearly define your ideal customer by demographics and interests? If yes, social media advertising deserves a place in your strategy.
Most small businesses should start with one platform, prove profitability, and then expand. Trying to run campaigns across every platform simultaneously with a limited budget spreads your resources too thin and makes optimisation nearly impossible.
A sensible starting sequence for most UK small businesses is: Google Ads Search first, then remarketing, then Facebook or Instagram depending on your audience, then Bing Ads to capture additional search volume. LinkedIn enters the picture when you have a clear B2B proposition and the budget to support higher click costs.
