Database vs wall limits
First determine whether the offers are missing from the database or only filtered from a particular wall. The wall can use inventory rules, country/device eligibility, hidden items and campaign status to reduce what one visitor sees.
Sync pagination
Adscend synchronization walks paginated catalog responses; CPAlead uses its supported catalog limit. Run a fresh sync and review sync logs if the database count itself is unexpectedly low.
Provider eligibility
Upstream accounts may expose different inventory based on approval, geography, traffic type or provider-side availability. The platform cannot import offers the provider does not return to your account.
