How much to price an ad?

An amount that makes sense both for you and your advertisers. While generating revenue for you, ads should also be profitable for your vendors.

Trial and error or historical data (if you have been offering ads with fixed CPC) could be used, but there’s always the risk of under or overpricing your ads.

The right way? Let the competition decide the CPCs.If your vendors are willing to bid higher and still get high ROAS, let them pay.You can also set the reserve price if you do not want to start the competition from a minimal amount.

How does the reporting work?

Our intuitive dashboard shows the performance overview with all metrics in real time.

Real-time metrics, make it easier to provide support for your vendors and troubleshoot faster. You can export the performance with customizable metrics for external analysis.

Additionally, you can set up daily, weekly, or monthly email notifications with a snapshot of your reports.

How do you ensure ad relevance?

Well, the beauty of Topsort’s customizability kicks in again! We can use your platform’s relevance logic, use ours, or let us build relevance on top of yours.

With your platform’s relevance logic, if one of the products in the auction shows up organically on top of the search results, we give it a higher relevance compared to a product that wouldn’t show up organically on the second page. A product that’s not relevant according to your platform’s logic, can not win the auction and show up as sponsored listings. In other words, a “Bluetooth speaker” won’t appear among the sponsored listings when a user searches for “gaming laptops” no matter how high they bid.

We can also build relevance on top of yours, which is what we recommend for increased relevance. You can also feed user cohorts like zip codes, cities, and new vs returning users into our API for increased relevance.
