Frequently Asked Questions

Answers to common questions about joining Carbon

Can I display your ads on my site?

Our network operates on an exclusive invitation-only basis. We carefully select both publishers and advertisers. If you are interested in having your site reviewed for consideration, continue reading for more information.

What do you look for in an applicant?

Several factors are reviewed when considering requests to join the network.

  1. We look at how relevant our ads will be to your audience.
  2. We look at your average number of monthly page views
  3. We look at whether your site is actively maintained.
  4. We look at whether there is a vacancy in the network.
  5. We look at your ability to comply with our terms of service.

Am I allowed to display other ads on my site?

We pride ourselves on being an exclusive ad network. When you accept our invitation, you are entering into a partnership where only ads from Carbon can be displayed on your site. Please refrain from using Carbon as backfill for any other ad networks.

What is the acceptable ad placement and behavior?

  • The ad should be visible during the initial page load for the 1440 × 900 pixels browser viewport.
  • The image size needs to be 130 × 100 pixels for the classic ad format.
  • The ad description must stay visible regardless of the container and viewport dimension.
  • The ad can only refresh when the page content changes or the site visitors trigger an event. For example, you are not allowed to refresh the ad using a timer.

Do you have any policies about how ads should behave on a mobile site?

The advertisement must be visible within 3x of the mobile viewport height, starting from the top of the mobile browser. A mobile device with a viewport height of 375 pixels needs to have the ad visible within 1125 pixels from the top of the browser. The ratio is the same for both portrait and landscape views.

The general principle is that the site visitors can view the ad with only a one-tap scroll. Optionally, you can choose to prevent the ad from loading when viewed on a mobile browser.

How much will I make?

We pay by the number of ad impressions served, but take your audience engagement rate (CTR) into consideration as we strive to maintain a high level of performance across the network. The site demographic and the ad network demand will also determine the CPM you receive. The realistic CPM will be around $0.50–$1.00.

What is your primary target audience and demographic?

We serve paid ads to regions where English is the most used language. Therefore, you can expect a near 100% fill rate from areas in United States, Canada, and some European countries.

In some cases, we will also serve paid ads to other regions according to the networks demand.

How does the payout work?

By the 15th of each month, you will receive payment for ad impressions served the previous month. The earnings will be sent to your BuySellAds account where you can accumulate the earnings for withdrawal.

What is the minimum payout requirement?

The minimum payout requirement is $1.

What earnings withdrawal method do you support?

We support the following withdrawal methods:

  • PayPal with the minimum balance for withdrawal is $20.
  • Check with the minimum balance for withdrawal is $50.
  • Wire Transfer with the minimum balance for withdrawal is $500, and there is a $35 fee. We use for wire transfers. Note that you are not required to open an account with to receive funds from BuySellAds.

Why don’t my page views and ad impressions match?

The ad tag is JavaScript. The script must fully execute, retrieving an ad from our server to increment the number of impressions served by your site.

To understand a discrepancy between page views and ad impressions, there are several factors to take into consideration, including the following:

  • Is the ad tag installed on every page of your site?
  • Website analytics reporting is not 100% accurate.
  • Bots account for as much as 80% of website traffic.
  • Ad blockers.
  • JavaScript is disabled.
  • Settings that interfere with the loading of our ads.
  • Other utilities that prevent our script from executing.
  • JavaScript errors on the page.
  • Leaving a page before the ad loads.

For these reasons, page views and ad impressions are unlikely to exactly match.
