If you run a successful Search and Display campaign to drive action and then decide to run a Video campaign with the same objective,why should you keep the Video campaign in the same account as the other campaigns?

By keeping the Video campaign in the same account as the other campaigns,you ensure a consistent conversion tracking setup across all campaigns.This helps prevent any discrepancies or double-counting of conversions.If the campaigns were in separate accounts,there's a possibility that a user who interacts with multiple campaigns might trigger conversions in both accounts.Having them in the same account ensures that Google Ads can de-duplicate these interactions and give a clearer picture of the conversion journey.
