Ad Relevance Diagnostics: Fix Quality, Engagement, and Conversion Rankings
Audit all three relevance diagnostics with customer economics, missing-data handling and a bounded decision plan.
This guide is an audit procedure for quality, engagement and conversion diagnostics together. The quality-ranking guide explains the metric; here the goal is deciding what to check or change without confusing a rank with a cause.
Record the diagnostic panel safely
Synthetic instructional panel, not an account screenshot: adA has an above-average diagnostic and CPA $14.20; adB has a below-average diagnostic and CPA $51.80. These figures do not establish that the ranking caused the cost difference. Different offer, eligibility, placement, conversion delay or events may explain it.
| Audit field | Record from the actual report | Evidence limit |
|---|---|---|
| Quality | Exact available label and report scope | Not a fixed CPM multiplier |
| Engagement | Exact available label and CTR definition | Attention does not prove useful customers |
| Conversion | Exact available label and optimization event | Check business payment/qualification definition |
| Missing diagnostic | Unavailable/hidden with actual report conditions | Do not infer good or bad quality |
| Mature outcome | Net orders/qualified leads and contribution | Attribution is not incremental lift |
Check the whole chain before narrowing
- Verify tracking, event duplication, paid orders and lead qualification. A conversion diagnostic cannot repair missing business records.
- Inspect offer truth, stock, destination and mobile checkout. Correct a confirmed defect before testing audience breadth.
- Check actual placement/audience/bid mix and auction-cost observations; a high CPM does not identify the creative cause.
- Read all available diagnostics with comparable mature CPA and customer quality. Do not assume missing fields are available after a universal impression threshold.
- Only then form one audience/creative/page hypothesis. Narrowing the audience can lose useful customers and is not a guaranteed diagnostic fix.

A combined decision matrix
| Pattern | Hypothesis to investigate | Action/acceptance |
|---|---|---|
| Quality low; customers complain | Misleading or unsuitable message | Correct verified claim/rights defect immediately |
| Engagement low; paid-customer CPA acceptable | Fewer but useful responses | Wait within limits; inspect quality rather than chase CTR |
| Engagement high; conversion low | Offer/page/event or customer-fit problem | Reproduce path and reconcile payments before one-change test |
| All ratings missing | Report availability/eligibility/data limitation | Use real outcomes and document missing diagnostics |
| Ratings improve; contribution falls | Attention or customer mix may have changed | Do not scale from labels; evaluate mature economics |
Approve and measure a single next action
Set supported assignment, unchanged offer/event/eligibility, approved spend/cash-loss caps and conversion maturity. Keep an inconclusive option for sparse outcomes. Record the actual diagnostic panel and commercial result after the change; a before/after correlation is not proof of causal savings.
In NovaStorm, prepare the audited brief and paused campaign/local ad-set drafts for user review. Diagnostics must come from a separately verified advertising report; no retrieval or automated ranking fix is promised.
