What happens if there is no banner

The honest answer is that nothing happens for a while, and then several things happen at once. It is worth knowing the order, because the first consequence for most small sites is not a fine.

What usually comes first

Complaints. A visitor who notices trackers before any question was asked can complain to the supervisory authority — the National Centre in Moldova, ANSPDCP in Romania — and it costs them nothing to do so. The authority then asks you to explain. Answering means describing what your site loads and showing what your visitors agreed to; without consent records there is nothing to show, and the conversation gets longer.

Competitors and clients are the other common route. In agency work especially, a compliance questionnaire from a corporate client is a far more frequent trigger than a regulator, and a missing banner can hold up a contract.

Fines, realistically

The headline GDPR figures — up to 20 million euro or 4% of worldwide turnover — are the ceiling for the worst cases, and they are not what a small site is looking at. National cookie-related penalties across Europe have typically landed in the hundreds to low tens of thousands of euro, scaled to the size of the business and to whether the operator fixed the problem when asked.

What raises a penalty is not the missing banner itself so much as what surrounds it: ignoring the authority's first letter, continuing after being told to stop, or a banner that pretends to ask while loading everything anyway. That last one — a purely decorative notice — is treated worse than no banner at all, because it misleads the visitor.

The consequence that arrives soonest

For most sites it is Google, not a regulator. Since March 2024, advertisers serving EEA traffic have needed Consent Mode v2 signals for remarketing and audience features to keep working. Without them, remarketing lists stop filling and conversion data degrades. There is no letter and no fine — the numbers simply get worse, and the cause is not obvious unless you know to look.

What it costs to fix versus to ignore

Putting a banner in place is a ten-minute job and, on a small site, free. The cost of ignoring it is mostly measured in time: answering an authority's questions without records, reconstructing what your tags have been doing, explaining the gap to a client mid-contract. The financial risk is real but secondary to the disruption.

If you have been running without one

• Do not panic and do not backdate anything. Fabricated consent records are a far worse problem than none.
• Find out what your site actually loads today.
• Install a banner that genuinely blocks, and start recording answers from that point on.
• Write down when you fixed it. Acting promptly once you knew is exactly what regulators weigh in your favour.
