Capture versus creation
Google Ads captures demand that already exists. Somebody has a problem, types it, and your ad appears. You are competing for a person who has already decided they need something.
Meta Ads creates or accelerates demand. Nobody opens Instagram looking for a pest control company. You are interrupting someone who matches a profile, which means the creative has to do the work that the search query does on Google.
Everything else — cost per click, lead quality, how fast you see results — follows from that one difference.
| Criterion | Google Ads | Meta Ads |
|---|---|---|
| How demand is reached | Captures people already searching | Interrupts people who fit the profile |
| Intent at the moment of the ad | High — they typed the need | Low to none — they were scrolling |
| Typical cost per click | Higher | Lower |
| Typical cost per lead | Often lower, because intent is higher | Varies more with creative quality |
| Lead quality | Usually stronger for services | More variable; needs qualification |
| What it depends on most | Keywords, negatives, landing page | Creative and audience |
| Speed to first results | Days | Days, but needs creative iteration |
| Works for demand that does not exist yet | No | Yes |
When Google should get the budget first
When people search for what you sell. Urgent services, professional services, anything with a clear problem-solution shape: a lawyer, a locksmith, a clinic, solar installation, pest control, car repair.
When the purchase is considered and researched, so the person is actively comparing options rather than discovering that the category exists.
When you have a small budget and need it to work quickly. Intent does a lot of the heavy lifting, which means less money spent teaching an audience who you are.
When Meta earns its place
When the product is visual, or when seeing it is what creates the want — property, interiors, aesthetics, hospitality, e-commerce.
When demand does not exist as a search. If your customers do not know your category exists, no amount of Google budget will find them, because they are not typing anything.
For retargeting, which is where Meta is at its most efficient regardless of sector. People who visited your site and did not convert are cheap to reach and far more likely to come back.
When you need volume at the top of the funnel and have the sales capacity to qualify it.
Running both without wasting either
Most lead-generation businesses here end up with Google carrying demand capture and Meta doing two jobs: reaching people before they search, and retargeting the ones Google already sent.
The mistake is running them as separate experiments and comparing cost per lead directly. They produce different leads at different stages, so a like-for-like comparison flatters Google and makes Meta look wasteful, which leads people to switch Meta off just as it starts feeding Google.
If you can only afford one, and people search for what you sell, start with Google. Intent is the cheapest advantage in paid media. Add Meta once Google is stable and you know what a lead is worth.
How to split the money
There is no universal ratio, but there is a sensible sequence. Put the budget on the channel that matches existing demand until it is capped — that is, until you are showing for the searches that matter and still converting profitably. Only then move money to the other channel.
If Google is capped and still profitable, more budget there is the easiest return available. If Google is running at full budget on terms that do not convert, the problem is the account, not the allocation, and moving money to Meta will not fix it.
Keep a retargeting budget on Meta almost regardless of size. It is usually the cheapest conversion in the account.

What is actually specific to Portugal
Two things genuinely change here, and both are about language rather than platform.
First, the variant. Ads and creative written in Brazilian Portuguese read as foreign to a Portuguese audience on both platforms, but the damage differs. On Google it costs you search volume, because the keywords are wrong. On Meta it costs you credibility, because the copy sounds off in a feed where everything else sounds local.
Second, the search terms report. Google gives you a full account of what people typed, and in Portuguese that report is where the waste is found. Meta has no equivalent, which means Meta waste shows up as poor results rather than as a list you can read and block. If you cannot read Portuguese, Google is the channel where the blind spot has the higher price — and also the one where it is fixable.
In short
Google for demand that exists, Meta for demand you have to create or recover. If people search for what you sell, start on Google, get it stable, then add Meta for reach and retargeting.
In Portugal, the deciding factor is rarely the platform. It is whether the Portuguese on your ads and landing pages was written by someone who speaks it, and whether anybody is reading what your traffic actually searched for.
