Hygiene factors are the 12-point checklist that must pass before any Meta optimisation begins.
Hygiene factors are Meta Catalyst IQ's 12-point account-hygiene checklist. Pixel plus CAPI dual firing, ad-set naming taxonomy, event dedup, exclusion audiences, geo-negatives, age caps, single interest cluster per ad-set, CBO off for testing, dynamic creative isolated, LTV events server-side, WhatsApp click mapped, DPDP consent gated. Every check must pass before optimisation starts.
How it works.
Most Meta accounts are optimised before they are measured. A creative test looks like a win, spend is scaled, and then CPL doubles the following month. Nearly every time the cause is upstream — a duplicate event, a mis-mapped audience, a CBO setting that hides ad-set truth, or a broken consent gate that silently loses form submissions. Hygiene factors exist to stop that pattern. It is a preflight, not a philosophy. Every check is binary. Every failed check gets a specific ticket with a specific owner and a specific fix window.
- Pixel plus CAPI dual firing. Client and server events for every conversion, dedup on event_id.
- Ad-set naming taxonomy. SLC format on every ad-set — see the SLC Framework.
- Exclusion audiences and geo-negatives. Existing patients, staff, off-service cities and PIN codes suppressed from every prospecting ad-set.
- Interest cluster and age caps. One interest cluster per ad-set. Age and gender caps aligned to the specialty's real patient profile.
- CBO off during testing, dynamic creative isolated. So ad-set-level truth is not laundered by budget shifting or creative combination noise.
- LTV, WhatsApp and DPDP wiring. Server-side qualified-lead event, WhatsApp click event mapped as a lead surface, and a DPDP-compliant consent gate on every form.
Why it matters for
Indian healthcare.
Hygiene is not just a performance concern for healthcare accounts — it is a compliance concern. Meta's healthcare category restrictions prohibit personal-attribute targeting, so age and gender caps must be tightened deliberately rather than left at defaults that Meta will later reject. ASCI's rules on unsubstantiable claims mean creative copy has to be reviewed inside the hygiene pass. NMC's Code of Ethics restricts what a treating doctor can say in an ad, so any physician-branded creative needs a compliance review before it fires. DPDP Act 2023 Section 5 requires an explicit consent gate on every lead form, and Section 8 governs how the resulting PII sits in the CRM. ART Act 2021 adds further restrictions for IVF accounts. Hygiene is the layer where legal, media, and analytics agree on the same account state.
How ICG uses this.
Meta Catalyst IQ runs the 12-point hygiene sweep as the first module on any onboarded account. Across the 23+ Meta accounts ICG manages — Rs 9.1 Cr per month in aggregate spend, portfolio median CPL Rs 1,581 — the sweep is re-run weekly, and any regression fires a Slack alert against the account owner. The long-term comparison view (below) tracks pre- versus post-hygiene performance so the recovered spend is auditable. Full workflow lives at Meta Catalyst IQ.
| Hygiene check | What breaks if it fails | Typical fix window |
|---|---|---|
| Pixel + CAPI dual fire | Attribution loss of 20-45% | 2-4 days |
| SLC naming taxonomy | Cannot slice spend by dimension | 1-2 days |
| Exclusion audiences | Spend hits existing patients | Same day |
| Geo negatives + PIN caps | Leads from out-of-service PINs | Same day |
| CBO off during testing | Ad-set truth gets laundered | Same day |
| DPDP consent gate on form | Legal exposure + Meta form risk | Same day |
Frequently asked questions.
Why run a hygiene check before optimising?
Because every optimisation lever assumes the account is measuring the right thing. If the pixel double-fires or CAPI is missing, CPL is wrong. If ad-sets are misnamed, spend cannot be sliced. If exclusion audiences are missing, spend overlaps. Fixing hygiene first turns a noisy account into a signal-rich one, so every subsequent test actually teaches you something.
How long does a hygiene fix take?
On the 23+ Meta accounts ICG manages inside Meta Catalyst IQ, the first hygiene pass takes about a week — pixel plus CAPI plumbing, event dedup, naming taxonomy migration, and DPDP consent-gate audit. After that, hygiene is monitored continuously, and any regression fires a Slack alert. The one-week upfront investment usually recovers 15-30% of wasted spend.
What breaks first without CAPI?
Attribution. Since iOS 14.5 and steadily tightening browser tracking, pixel-only setups miss 20-45% of conversions. Meta then optimises against a partial signal and pushes spend toward the audiences that look cheap. Server-side CAPI closes the gap and lets Meta learn from qualified leads posted from your CRM, not just from browser events.
Does DPDP Act consent belong in hygiene?
Yes. DPDP Act 2023 Section 5 requires explicit consent before collecting personal data through a lead form. A missing or ambiguous consent checkbox is not only a legal exposure — it is also the fastest way to lose Meta form access if a complaint is filed. Meta Catalyst IQ audits the consent copy, the checkbox default, and the privacy-policy link on every live form.
