Yes, but if a user doesn’t convert the advertiser will see worse performance metrics as cost per click/conversion/install is higher. That isn’t a good long term outcome for the platform, since advertisers can switch their budgets elsewhere (to Google/Youtube)

There’s a delicate balance, more impressions isn’t always a good outcome. Id assume here given the battle against ad blockers that the platforms do believe the aggregate impression mix leads to good performance for advertisers though
