Google Ads or Facebook Ads: which is best for your business?

If you have a budget for online advertising, sooner or later you face the question: should you spend it on Google Ads or on Facebook and Instagram ads?
Both platforms can bring excellent results, and both can burn money quickly if they are used wrongly.
The right choice depends on what you sell, who your customers are and where they are in their buying journey.
In this guide we compare the two, explain when each one works best, and show how many businesses get the best results by combining them.

The basic difference: intent versus interest

The most important difference is how people find your ad.

Google Ads is mainly based on search intent.
People type what they are looking for, such as “accountant in Barcelona” or “buy running shoes”, and your ad appears in the results.
They already have a need, and you show up at the moment they are looking for a solution.

Facebook and Instagram ads, run through Meta, are based on interests, behaviour and demographics.
People are scrolling through their feed, not searching for anything.
Your ad has to catch their attention and create interest, sometimes before they even know they need your product.

In short, Google is great for capturing existing demand, while Meta is great for creating new demand.

Google Ads explained

Google Ads covers several types of campaigns.

• Search.
  Text ads on Google search results, based on keywords.
• Shopping.
  Product ads with image, price and shop name, based on a product feed from your webshop.
• Performance Max.
  Automated campaigns that show ads across Search, Shopping, YouTube, Display, Gmail and Maps.
• Display.
  Banner ads on websites in Google’s network.
• YouTube.
  Video ads before and during videos.

You usually pay per click, and the price depends on competition for each keyword.
In competitive industries such as legal services, insurance or finance, a single click can be expensive, while niche or local keywords can be much cheaper.

Strengths of Google Ads

• You reach people at the exact moment they are looking for what you offer.
• Leads and sales from search are often of high quality.
• Results can come quickly, sometimes within days.
• Shopping ads are very effective for webshops with good prices.
• Easy to target by location, language and device.

Weaknesses of Google Ads

• Clicks can be expensive in competitive markets.
• You can only reach people who are already searching, so it does not create new demand.
• Poor keyword choices and missing negative keywords can waste budget fast.
• Automated campaign types give you less control and insight.

Facebook and Instagram ads explained

Meta ads appear in the Facebook and Instagram feeds, stories, reels, Messenger and partner apps.
You choose an objective, such as awareness, traffic, leads or sales, and Meta shows your ad to people it expects to take that action.
You can target by location, age, interests and behaviour, or upload customer lists and create lookalike audiences of people similar to your best customers.

Strengths of Meta ads

• Huge reach at a relatively low cost per impression.
• Strong visual formats with images, video and carousels.
• Great for creating interest in new products, brands and offers.
• Very effective retargeting of people who visited your website.
• Lead forms let people sign up without leaving the app.

Weaknesses of Meta ads

• People are not actively looking for your product, so lead quality can be lower.
• Ads need fresh creative regularly, because people get tired of seeing the same image.
• Tracking has become harder because of privacy changes in browsers and phones.
• Some industries have special rules or restrictions on targeting.

Which one should you choose?

Choose Google Ads first if

• People already search for your product or service.
• You offer services that people need urgently, such as repairs, legal help or emergency services.
• You run a webshop with products people compare on price.
• You sell B2B services that buyers research on Google.
• You serve a local area, where “near me” searches matter.

Choose Facebook and Instagram first if

• Your product is new and people do not know to search for it yet.
• Your product is visual, emotional or an impulse buy, such as fashion, food, interiors, gifts or travel.
• You want to build a brand and an audience in a new market.
• You promote events, courses, launches or limited offers.
• You want to collect leads at a lower cost and nurture them over time.

Why the best answer is often both

Most customers do not buy the first time they see a brand.
They might see an Instagram ad, visit your website, leave, search on Google a week later and then buy.
That is why many businesses get the best results by using the two platforms together.

• Use Meta to create interest and reach new audiences.
• Use Google Search and Shopping to capture people when they are ready to buy.
• Use retargeting on both platforms to bring back visitors who did not buy.

Start with the platform that best fits your product, and add the other when the first one runs well.

How much should you spend?

There is no fixed answer, but there are some useful rules.
Start with a budget you can afford to test with for at least one to two months, because both platforms need time and data to learn.
Calculate how much a customer is worth to you, and how much you can pay to win one.
Then compare that with the cost per lead or sale you see in the first weeks.
Increase the budget step by step on campaigns that are profitable, instead of spreading a small budget across too many campaigns.

Tracking is essential on both platforms

Without proper tracking, both platforms are flying blind.
Install Google Analytics 4, Google Ads conversion tracking and the Meta Pixel on your website.
Where possible, add server-side tracking such as the Meta Conversions API, which is less affected by browsers and ad blockers.
Use a cookie banner with Google Consent Mode, so tracking respects your visitors’ choices under GDPR and still gives the platforms useful data.
Define clear conversions, such as purchases, form submissions and calls, and check that they are registered correctly before you spend real money.

The landing page decides the result

Even the best ad will fail if it sends people to a slow or confusing page.
The page should match the ad, load fast on mobile, and make the next step obvious.
For campaigns, a dedicated landing page often converts far better than your homepage.

Ad creative that works

On Google

Search ads are mostly text, so every word counts.
Put the main keyword in the headline, show a clear benefit, and add a reason to click now, such as free delivery, a fast reply or a free quote.
Use all the extra assets Google offers, such as sitelinks, callouts, phone numbers and location, because they make your ad larger and more useful.
For Shopping ads, the quality of your product feed is your creative, so use clear titles, good images and correct prices.

On Facebook and Instagram

Here the image or video does most of the work.
The first second must stop the scroll, so show the product, the result or a face, not just your logo.
Short vertical videos often perform best, especially in reels and stories.
Keep the text short, speak directly to the customer and make the offer clear.
Test at least three different creatives in each campaign, and replace the weakest ones every few weeks.

A simple test plan for your first month

1. Week 1.
   Set up tracking, create a landing page and launch one campaign on the platform that fits your product best.
2. Week 2.
   Check search terms or audiences, remove what does not work and add negative keywords.
3. Week 3.
   Test new headlines, images or videos against the best performers.
4. Week 4.
   Calculate cost per lead or sale, decide whether to scale up, and consider adding retargeting on the other platform.

Common mistakes

• Using broad keywords without negatives on Google.
  You end up paying for clicks from people looking for something else.
• Boosting random posts on Facebook.
  Boosting without a clear goal and audience rarely brings sales.
• Changing campaigns every day.
  Both platforms need time to learn, so give each change a few days.
• Not testing creative.
  Try several images, videos and headlines, and keep the winners.
• Ignoring mobile.
  Most ad clicks come from phones, so the whole experience must work on a small screen.
• Not measuring profit.
  Clicks and likes are not the goal, profitable customers are.

Advertising in several countries

Both Google and Meta make it easy to advertise across borders.
Create separate campaigns for each country and language, with ads and landing pages in the local language.
Prices per click and competition differ a lot between countries, so a keyword that is expensive in Germany might be cheap in Spain or Denmark, and the other way around.
Remember local holidays, currencies, shipping and payment methods, and adjust your offer to each market.
