User advertisements allow you to notify users of experiences they can play, items they can purchase in the Marketplace, or groups they can join. When a user clicks the ad, it opens the main page of whatever you are advertising.
Bidding System
Advertisement space works on a bidding system where the higher you set your Daily Budget amount in relation to other creators' bids, the more likely your sponsored experience will display within the Sponsored category on the Home and Discover pages. For example, if there are three sponsored experiences in the bidding system, advertising space is split according to how much each user has bid:
| User | Bid Amount | Result |
|---|---|---|
| A | 50 Robux | — |
| B | 100 Robux | User B's sponsored experience will display twice as often as User A's. |
| C | 300 Robux | User C's sponsored experience will display six times as often as User A's, and three times as often as User B's. |
Creating Ads
If you're running an ad blocker application, you must temporarily disable it in order to create an ad.
There are three types of image advertisements you can create:
| Type | Size | Placement |
| Placement Banner | 728×90 pixels | Top or bottom of the Roblox website. |
| Skyscraper | 160×600 pixels | Left or right-side of the Roblox website. |
| Rectangle | 300×250 pixels | Right-side or bottom of the Roblox website. |
All advertisement images must be in either .png or .tga format, and they must adhere to the Community Rules and Terms of Use. To create an ad:
Navigate to Roblox.com.
In the horizontal navigation, select the Create tab. The Experiences space displays.
Click the dropdown menu to the right of the experience you want to create an ad for, then the Advertise menu item. The Create User Ad space displays with three ad templates.
In the Name your Ad field, enter what you want to display when users hover over the ad.
In the Upload an Ad field, drag in the image you want to use for your ad or upload it through the Select an image from your computer button.
Click the Upload button. The User Ads page displays.
Your ad is now within the moderation queue and is only visible to you on the User Ads page. Once the Moderation team approves your ad, you can run an ad cycle.
Running Ad Cycles
Ad cycles run for 24 hours, and the ad displays to users according to the advertising space bidding system for that time period. To run an ad cycle:
Navigate to Roblox.com.
In the horizontal navigation, select the Create tab. The Experiences space displays.
In the left-hand navigation, select User Ads.
Click the dropdown menu to the right of the ad you want to run, then select the Run Ad menu item. An additional Bid in Robux field displays.
In the Bid in Robux field, enter how many Robux you want to spend to advertise your ad.
Click the Run button. A Make Ad Bid dialog displays that confirms both the amount of Robux you want to spend, and how many impressions Roblox estimates you will receive with that bid.
Click the Place Bid button to confirm the ad cycle.
Once the ad cycle runs, you'll be able to track the ad's performance on the same page. Roblox tracks the following performance metrics:
| Metric | Description |
| Bid | The amount spent for the current ad cycle. |
| Clicks | Every time a person clicks on your ad for the current ad cycle. |
| CTR ("Click Through Rate") | Clicks divided by impressions. |
| Impressions | Estimate for the number of times the ad was served. |
| Total Bid | The amount spent for every ad cycle the ad has completed. |
| Total Clicks | The sum of all clicks for every ad cycle the ad has completed. |
| Total CTR | The sum of all clicks divided by the sum of all impressions for every ad cycle the ad has completed. |
