How to compare campaign performance across five ad platforms

Google, Meta, Microsoft, Pinterest and Reddit do not always define or attribute outcomes in the same way. A fair comparison starts by making those boundaries explicit.

Use the same reporting period

A platform using a different date range can look stronger or weaker before you have compared any actual campaign result. Start with one shared period and document the timezone behind it.

Compare common metrics first

Spend, impressions, clicks and reported conversions create a useful baseline. Revenue, ROAS, CPC and CPA become more meaningful after you confirm how each provider produced the number.

Keep provider context visible

Unification should not erase account names, campaign identities, currencies or attribution differences. The shared view is the starting point for analysis, not a claim that every platform measures identically.

Review through one repeatable lens

Use the same filters, breakdowns and export structure each reporting cycle. Consistency makes changes easier to investigate without promising that a dashboard alone improves performance.
