• This refers to the number of days it takes for a newly adopted Smart Bidding strategy to take hold after a campaign’s first recorded online or offline conversion.
• This is the total load time of a website page, such as a confirmation page, which is used to measure a consumer’s conversion actions on the advertiser’s site.
• This refers to the time it takes for an advertiser to create a conversion measurement strategy for their Google Ads account.
• This is the amount of time that occurs between the selection of an ad and an advertiser having uploaded an offline conversion or completed the conversion on a site.

The correct answer is: This is the amount of time that occurs between the selection of an ad and an advertiser having uploaded an offline conversion or completed the conversion on a site.

Explanation: Conversion delay is characterized by the time lapse between when a user clicks on an ad and when the user actually completes a conversion on a site. If offline conversion data is being uploaded, the delay includes the time it takes for the user to convert and for the conversion to be uploaded into Google Ads. Evaluating the target Return on Ad Spend (ROAS) and maximizing conversion value performance must factor in this delay. Tools like bid strategy reports can be used to identify the conversion delay and exclude this duration from the analysis. Additionally, learning for newly imported conversion goals starts only once the goal becomes biddable by including it in conversions.
