“Should I advertise on Google or on Instagram?” It’s one of the first questions any business asks when it wants to sell more through advertising. The short answer is that they don’t compete with each other: they serve different moments in the customer journey. The long answer is this guide, where we compare Google Ads and Meta Ads so you know which suits your business, where to start and when it makes sense to use both.
The core difference: demand versus discovery
Google Ads captures demand that already exists. Someone types what they need (“blind repair Andorra”, “buy Jordan trainers size 9”) and your ad appears at exactly that moment. The intent is clear, which is why it tends to convert well.
Meta Ads creates demand. On Facebook and Instagram nobody is looking for your product: they are scrolling through photos, videos and messages. Your ad interrupts that moment and has to spark interest. In return, you can reach many people who don’t yet know they need you, with very powerful targeting by interests and behaviour.
Google answers “I need it”. Meta triggers “I didn’t know I wanted it”.
How Google Ads works
Google Ads groups several campaign types. The most common for a small business are:
- Search: text ads in Google results when someone searches for your keywords. It is the heart of Google Ads.
- Shopping: product listings with photo and price on Google. Essential for many online stores.
- Performance Max: automated campaigns that spread your ads across Search, Shopping, YouTube, Gmail, Display and Maps.
- YouTube and Display: videos and banners, more focused on brand awareness.
You usually pay per click. The price of each click depends on the competition for that keyword: sectors such as lawyers, insurance or home renovation have far more expensive clicks than others.
When Google Ads is the better fit
- Services people search for when they have a problem: garages, clinics, renovations, accountants, locksmiths…
- Local businesses that want to appear when people search nearby (combined with local SEO).
- Online stores with products people search for by name, brand or model.
- B2B sales where the client researches before asking for a quote.
How Meta Ads works
Meta Ads lets you advertise on Facebook, Instagram, Messenger and its partner app network from a single dashboard. Its strengths are:
- Visual formats: image, video, carousel, reels and stories. Ideal for products that sell through the eyes.
- Targeting: by location, age, interests and behaviour, plus lookalike audiences based on your customers.
- Retargeting: reaching people again after they visited your website, watched your videos or engaged with your profile.
- Volume: you can reach a lot of people on moderate budgets.
You pay per impression or per result, depending on the objective. The cost depends on competition for your audience, the time of year (everything goes up at Christmas) and, above all, how good your ads are.
When Meta Ads is the better fit
- Visual or impulse-purchase products: fashion, footwear, cosmetics, home décor, collectibles…
- Launches and new products nobody is searching for yet.
- Businesses whose audience is clearly defined by interests.
- Winning back visitors who didn’t buy the first time.
We have seen it in our own projects: for a sneaker e-commerce store, Meta Ads campaigns in peak season pushed December net sales 137% above October’s. At Throne of Cards, a trading card store, we run campaigns for every new collection launch, and every revenue peak matches one of them.
Quick comparison
- Intent: Google, high (the customer is searching). Meta, medium or low (you have to spark it).
- Format: Google, mainly text and product listings. Meta, image and video.
- Speed: both can deliver results within days if the setup and the website are right.
- Creative: on Google, keywords and copy matter most; on Meta, the quality of the video or image is decisive.
- Scale: Google is limited by how many people search for what you offer; Meta lets you reach broader audiences.
- Best for: Google, services and specific searches; Meta, visual products, launches and retargeting.
What if my budget is small?
With a tight budget, it is better to focus on one platform and do it well than to spread a little money across several. As a general rule:
- If your customers already search for you, start with Google Ads (Search or Shopping).
- If you sell something visual or new, start with Meta Ads.
- If you’re not sure, look at how customers find you today: if they arrive through Google, or through word of mouth and social media, that is your clue.
Before investing in either, make sure your website is ready to convert and your tracking works. Paying for ads that send people to a slow or confusing website is the quickest way to waste your budget. We explain it in why an online store doesn’t sell.
When to combine both
The best strategies usually use both platforms, each in its own role:
- Meta Ads introduces the brand and product to new people.
- Google Ads captures those who later search for your name or your product.
- Retargeting on both brings back those who were about to buy.
Combining them makes sense when one of them already works and you want to grow, or when your product needs both stages: discovery and search.
Frequently asked questions
Which is cheaper, Google Ads or Meta Ads?
It depends on the sector. On Meta, clicks and impressions are usually cheaper, but purchase intent is lower. On Google, clicks can be more expensive, but the people who click are usually closer to buying. What matters is not the price of a click but the cost per sale.
How much should I invest to start?
Enough for the platform to have data to learn from and for you to draw conclusions. A budget that is too small and spread across many campaigns almost never works. It is better to start with one well-focused campaign and scale up when the numbers justify it.
Can I manage the campaigns myself?
Yes, both platforms let you do it. The difference lies in time and experience: campaign structure, tracking, creatives and continuous optimisation. Many businesses start on their own and look for help when spending grows and every mistake becomes expensive.
Does Meta Ads work for B2B businesses?
It can, especially for brand awareness and retargeting, but in B2B Google Ads, LinkedIn and a good website with real case studies usually work better. It depends on how well defined your ideal customer is.
In short
Google Ads is the best option when your customers already search for what you sell; Meta Ads, when you need to show it to them before they search. With a limited budget, pick one and measure it well; once it works, combine them. If you want to see what your campaigns could deliver, try the AVAR LAB simulator or ask us for a proposal.
