Your client is a sports retailer who’s launching a new basketball sneaker. They want to track how many people visit their site after seeing the sneaker ad. Which Floodlight tag would provide this information?

Why other options are in correct?

The Sales tag is useful on e-commerce sites where you would want to understand what was the sales value of the product which got sold. This way, you optimize the Campaign/Line where the sales value is higher.

Any floodlight tag option is also incorrect, because you want to specify as to how many conversions you have got, as it would give important info to the bidding strategy for further improvement in campaign performance

Counter tag would be the right option as it counts the number of visitors on a specific page where the tag is placed. As the name indicates, it would count the number of people who visit the page.

Global site tag is specific to Google Ads tracking and won’t work on DV360. On Dv360, you must use the Floodlight tag. Under the FL tag, you can use either the counter tag or the sales tag. If your goal is to count conversion numbers, you sould you counter tag; however, if you want to track the sales value of the product sold, you should use the sales tag.
