FAQ

Questions,
answered.

01Where does BuyAds traffic come from?

From 240+ programmatic supply partners, including Google AdX, Magnite, PubMatic and Index Exchange, plus ad networks and direct publishers.

02What is programmatic advertising?

Programmatic advertising means ads are bought automatically in real-time auctions, one impression at a time, instead of through manual deals.

03Is Google AdX one of your partners?

Yes. Google AdX is one of the exchanges connected to the platform, alongside 240+ other supply partners.

04How many exchanges are you connected to?

More than 580 exchange connections from over 240 partners, and new supply is added almost every day.

05How do you buy the traffic?

Every impression is bought in a live real-time bidding auction over OpenRTB or XML.

06How do you keep bots out?

Every request is checked before we bid. Bots, data-center traffic and low-reputation sources are filtered out first.

07Can I choose which sources my ads run on?

Yes. Pick a quality tier per campaign, see every source and placement in reports, and block any of them in one click.

08Which countries do you cover?

Supply is available in 195 countries, on desktop and mobile.

09Which ad formats does the supply cover?

All six: Pop-Under, Push, Display, HTML5, Native and Video, bought through the same supply.

10What is an SSP?

An SSP, or supply-side platform, is the technology publishers use to sell their ad space to buyers in real-time auctions.

11What is the difference between OpenRTB and XML supply?

Both are ways for an exchange to send us a bid request. OpenRTB is the industry standard protocol, while XML feeds are a simpler format many ad networks still use.

12Which quality mode should I start with?

Standard is a sensible default for most tests. Choose Strict for offers with strict requirements, and Basic once an offer is proven and you want reach.

13Am I charged for traffic that fails the fraud checks?

No. Fraud filtering runs before the bid, and invalid traffic is not charged.

14Can I see which supply partner a visit came from?

Yes. Reports break traffic down to source and placement level, so you can see where visits came from and block any of them.

15Why can the same visitor reach me through several exchanges?

Publishers often sell through more than one exchange. A frequency cap limits how often the same visitor sees your page, whichever exchange they come from.

16Does more supply mean lower quality?

Not by itself. Every request is filtered before the bid, and your quality mode and block lists decide which sources your campaign buys.
