Facebook Ads vs Google Ads: Which Is Right for Your Business?

Google Ads is usually the better choice when people already search for what you sell, because you reach them at the moment they are looking. Facebook Ads (and Meta’s wider network, including Instagram) is usually better for creating demand, by putting a product or offer in front of people who fit your customer profile but are not searching yet. Plenty of businesses end up using both. Where you start depends on whether people are already looking for what you offer.

Below we cover how each platform works, where each tends to fit, and how to decide where a limited budget should go first. We have avoided generic cost benchmarks, because they rarely hold for a specific market.

Intent versus interruption

The easiest way to tell the two platforms apart is to think about what the person is doing when they see your ad.

On Google Search, someone has typed a query. They have told you, in their own words, what they want. “Emergency plumber Cardiff”, “accountant for limited company”, “buy oak dining table”. Your ad answers a request. This is often called intent-based or demand-capture advertising.

On Facebook and Instagram, someone is scrolling through updates from friends, creators and brands. They were not looking for you. Your ad has to earn attention and create interest. This is interruption-based or demand-generation advertising, and it depends on reaching the right people with something worth stopping for.

Neither approach is better in general, because they do different jobs. The first question is which of those jobs your business actually needs doing.

How Google Ads works

Google Ads covers several campaign types. For most small businesses, four matter.

• Search campaigns. Text ads shown on Google results pages for the keywords you choose. Most service businesses start here.
• Shopping campaigns. Product listings with images and prices, fed from a product feed in Google Merchant Center. Central for many ecommerce businesses.
• Performance Max. An automated campaign type that runs across Google’s inventory, including Search, Shopping, YouTube, Display, Gmail and Maps, using your assets and goals.
• Display and YouTube. Image and video ads across websites, apps and YouTube, mostly used for awareness and remarketing.

Search ads are sold through an auction. You set bids or a bidding strategy, and Google decides which ads appear based on bid and on ad quality and relevance. You usually pay when someone clicks. A well-built account groups closely related keywords with ads and landing pages written for them, which tends to raise quality scores and bring click costs down.

Where Google Ads tends to work well

• Urgent or needs-based services, such as trades, repairs, legal, medical and emergency work.
• Products people search for by name or type.
• Local businesses whose customers search with a location or “near me”.
• B2B services where buyers research specific solutions.

Where it can struggle

• New product categories nobody searches for yet.
• Very competitive keywords where larger advertisers push up click costs.
• Impulse or visual products that sell on looks rather than search.

How Facebook Ads works

Facebook Ads are managed in Meta Ads Manager, and campaigns can run across Facebook, Instagram, Messenger and Meta’s Audience Network. You choose a campaign objective, such as awareness, traffic, engagement, leads, app promotion or sales, and Meta optimises delivery towards that outcome.

Targeting is built around people rather than queries. You can define audiences by location, age, interests and behaviours, upload customer lists to create custom audiences, retarget website visitors through the Meta Pixel and Conversions API, and create lookalike audiences similar to your existing customers. Increasingly, Meta encourages broad targeting and lets its algorithm find the right people based on your creative and conversion data.

Because nobody is searching, creative does most of the work. The image or video, the first line of copy and the offer decide whether someone stops scrolling. On Meta, testing new creative usually moves results more than any targeting change.

Where Facebook Ads tends to work well

• Visual products such as fashion, homeware, food, beauty and gifts.
• Offers with broad appeal to a definable audience.
• Events, local promotions and openings.
• Lead generation where a simple form and a strong incentive make sense.
• Retargeting people who have visited your site but not converted.

Where it can struggle

• Urgent needs, where people go straight to search.
• Highly specialist B2B services with a small audience.
• Businesses without the capacity to produce fresh creative regularly.
• Regulated categories. Ads about housing, employment, credit, and social issues, elections or politics fall under Meta’s Special Ad Categories, which restrict targeting options.

Side-by-side comparison

How to decide where to start

If budget only allows one platform at first, work through these steps.

1. Check whether people search for what you sell. Use Google Keyword Planner (free inside a Google Ads account) to see whether there is meaningful search volume for your core services or products in your area. If there is, Google Search is a natural starting point.
2. Consider urgency. If customers usually need you now (a burst pipe, a broken boiler, a legal deadline), they will search. Prioritise Google.
3. Consider how visual and impulse-driven the purchase is. If your product sells on looks or lifestyle, Meta’s image and video formats suit it well.
4. Define your audience. If you can describe your ideal customer by demographics, interests or life stage but they do not search for your solution by name, Meta may reach them more efficiently.
5. Check your creative capacity. If nobody on the team can produce new images and short videos every few weeks, Meta will be harder to keep going. Search ads need copy and landing pages but far less ongoing creative.
6. Look at your sales cycle. Bigger, slower purchases often need both, with Meta building awareness and Google catching people when they are ready.
7. Start with a test. Run a focused campaign with one goal and a fixed budget for long enough to gather useful data, then decide.

Before spending anything, decide what success means for you in numbers. That might be a cost per enquiry, a cost per sale or a return on ad spend you can afford. Our guide on how to set marketing goals covers this in more detail.

Setting a sensible test budget

There is no single right amount to spend, and anyone quoting a fixed figure without knowing your market is guessing. Work backwards from your own numbers instead.

Start from what a customer is worth

Work out the average value of a sale or a new client, and how much of that you could afford to spend acquiring them while still making a profit. If a typical job is worth a modest amount and margins are thin, you need an efficient channel. If a client is worth a lot over several years, you can afford to pay more per enquiry.

Allow enough budget to learn

A budget so small that it produces only a handful of clicks a week will not tell you much. Both platforms need a reasonable volume of activity before their automated bidding settles. If budget is tight, narrow the scope rather than spreading it thin. Pick one service in one location, or one offer to one audience.

Separate testing from scaling

Treat the first few weeks as a paid experiment. The goal is to learn which keywords, audiences, creative and landing pages produce enquiries at a cost you can live with. Only increase spend once you have something that works, and increase it gradually so you can see whether results hold.

Examples by business type

These are illustrations rather than client results, showing how the reasoning above usually plays out.

A local electrician

Customers search when they have a problem or a project. Google Search campaigns built around keywords like “electrician Bristol” or “fuse board replacement”, backed by a well-kept Google Business Profile, are the obvious first step. Meta can help with local awareness but rarely brings in the bulk of the work.

An independent homeware shop selling online

Products are visual and often discovered rather than searched for. Meta campaigns with good product photography and short videos, plus retargeting of site visitors, are often a good start. Google Shopping becomes important as people start searching for the brand or specific product types.

A B2B software or consultancy firm

Search ads can capture buyers researching specific solutions, though keywords may be competitive. Meta can work for retargeting and for reaching some audiences. If your buyers are defined by job title and seniority, LinkedIn deserves a place in the comparison too.

A restaurant or venue

Meta suits promoting events, menus and atmosphere to local audiences. Google helps capture people searching for places to eat or book nearby, particularly through local search and Maps.

Using both platforms together

For many businesses the best setup gives each platform the job it is good at, and the four steps below tend to feed each other.

• Meta builds awareness among people who fit your customer profile but do not know you yet.
• Those people later search, sometimes for your brand name, sometimes for the category.
• Google captures that demand through search and shopping ads, alongside your organic listings.
• Retargeting on both reminds people who visited but did not buy.

A useful sign the combination is working is growth in searches for your business name. In Google Search Console, filter queries containing your brand and watch the trend after you start awareness activity on Meta. It is not proof on its own, but alongside enquiry numbers it gives a useful indication that people who saw your social ads are coming back to look for you.

The awkward part is attribution. Each platform tends to claim credit generously for conversions it touched, so platform-reported figures will often add up to more than your actual sales. Compare platform data with your own records and with GA4, and look at overall business results when you change spend. Our guide on measuring marketing ROI goes into how to handle this.

What matters more than the platform

Picking the platform is only part of it. The four things below affect performance on either one, and they are often where a struggling campaign is really going wrong.

Your landing page

Paid traffic sent to a slow or generic page wastes money on any platform. A landing page that matches what the ad promised, loads quickly on mobile and makes the next step obvious will usually do more for results than switching platforms. See our guide on what makes a good conversion rate for context.

Conversion tracking

Both platforms optimise towards the conversions you track. Set up Google Ads conversion tracking (or import from GA4) and the Meta Pixel with the Conversions API. Without accurate tracking, automated bidding is guessing.

Your offer

A clear offer beats clever targeting. “Free survey and fixed quote within 48 hours” gives people a reason to act now in a way that “quality service at great prices” never will.

Patience and enough data

Both platforms’ algorithms need conversion data to optimise. Changing campaigns every few days resets learning and makes it hard to judge results. Agree a test period and stick to it unless something is clearly broken.

Common mistakes to avoid

• Choosing a platform because a competitor uses it. Their business model, margins and audience may be different.
• Running Google Search with broad keywords and no negatives. Add negative keywords to exclude irrelevant searches and review the search terms report regularly.
• Using one tired creative on Meta for months. Performance usually declines as audiences see the same ad repeatedly.
• Sending all traffic to the homepage. Match the landing page to the ad.
• Accepting automated recommendations without review. Platform suggestions are designed to increase spend. Some help and some do not.
• Judging success by clicks or likes. Measure enquiries, sales and profit.

Picking your first platform

Google Ads and Facebook Ads are not really competitors. Google catches people who are already looking, and Meta reaches people who have not started looking yet. Start with the one that fits how your customers buy, track enquiries and sales rather than clicks, and add the other once the first is paying for itself.
