A consolidated structure is a way of organising a Meta ads account with as few campaigns, ad sets and audiences as the business genuinely needs, so that each ad set collects enough conversions for Meta’s delivery system to learn from. It replaces the older habit of splitting one budget across dozens of narrow ad sets, which people now call the legacy structure.
How consolidated structure works
Meta’s delivery system decides who sees your ads by predicting who is likely to take the action you asked for. Those predictions improve as an ad set records more of that action. Meta’s long-standing guidance is that an ad set needs roughly 50 optimisation events in the week after its last significant edit to leave the learning phase. Meta adjusts that threshold for some campaign types, so check the delivery column, but whatever the figure it counts per ad set, not per account.
Imagine a Manchester furniture retailer spending £3,000 a month and getting about 60 online orders. Split across twelve ad sets (one per interest, age band and placement), each ad set sees five orders a month and never stabilises. Put the same spend into two or three ad sets and each one gets enough orders for the system to find patterns.
In practice a consolidated account usually has one prospecting campaign and, where the audience is big enough, one retargeting campaign. Targeting is broad or uses Advantage+ audience, placements are left open, and the testing happens in the ads rather than in the audience. Advantage campaign budget often moves money between the remaining ad sets automatically.
What still deserves its own campaign
Consolidation is not the same as putting everything in one place. Separate campaigns still make sense when the goal is different (leads versus sales), when the margin or the offer is very different, when a special ad category applies to some products, or when you need a fixed budget for a particular area such as a single store’s catchment.
Why it matters
When an account spends a few hundred to a few thousand pounds a month, as many UK small businesses do, fragmentation is one of the main reasons accounts look unstable: costs swing week to week, ad sets sit in learning limited, and nobody can tell what is working because each slice has too little data to judge.
A tidier structure also lowers the chance that your own ad sets bid against each other for the same people, a problem known as auction overlap. And it makes the account readable. When you need to explain why costs rose last week, the answer is easier to find in three ad sets than in thirty.
Common mistakes
- Consolidating without enough conversions anyway. If the whole account gets 10 sales a month, merging ad sets will not reach 50 a week. Optimising for an earlier, more frequent step such as add to basket may be the honest fix.
- Merging very different offers. A £15 accessory and a £1,500 sofa in one ad set will usually see spend pulled towards whatever converts most often, not what makes the most profit.
- Treating the structure as the strategy. Fewer ad sets only helps if the ads inside them give the system distinct messages to work with.
- Restructuring every fortnight. Each rebuild resets learning, so constant reshuffling recreates the instability consolidation was meant to remove.
How to act on it
Start by counting. Export the last 90 days by ad set and note how many optimisation events each one recorded per week. Any ad set well below the learning threshold is a candidate for merging.
Next, group ad sets by what they are trying to achieve rather than by who they target. Keep the splits that reflect real business differences, such as separate budgets for new customers and repeat buyers, and fold the rest together. Move the variety into the ads: different angles, formats and offers. Then leave the new structure alone for at least two weeks before judging it.
This kind of rebuild is a routine part of my Facebook ads management service, where the first month usually starts with an account audit of exactly this sort.
