What is QPS Optimization?

Whenever you visit a website to read the latest news, you will see an ad. Let’s say you’ve looked for a new car recently and see an ad for the new BMW i4. Is this magic? How did it happen?

Well, with a ton of complex infrastructure - that is the short answer.

Each ad you see on a website with an optimized adstack is probably going through several actors in the ad ecosystem in pursuit of higher yield, personalized ads, and good conversions. Once you open the browser, requests may go through different platforms, such as the open source Prebid.org, centralized Amazon A9, and ad-serving built-in software - Open Bidding by Google. This infrastructure passes queries to each SSP, or Supply Side Platform, connected to it.

See, before an ad is served to you, there are several phases - a publisher has the inventory, then there are platforms that connect it to players that consolidate many publishers’ inventory - the SSPs. Usually, a website works with 10 to 30 different SSPs, and each must receive the information that there is a free space to show their ad.

Then the SSPs pass this information to the DSPs (Demand Side Platforms). The DSPs consolidate advertisers and develop the technology that enables them to spend their ad budget optimally in the right place at the right time.

In theory, an SSP like Appnexus sends a request to a DSP like The Trade Desk, there is a mix of cookie-matching in the process of delivery rates, ad sizes, cappings, etc., and in the end - The Trade Desk sees an opportunity for its client BMW, and sends back information that it can give as much as 1 dollar per 1000 impressions like these. Each so-called bid is then transferred to the Ad Server (let’s say Google Ad Manager), and as it collects them, it checks which is the highest price and displays the advertisers' banner ad from the DSP.

It’s a rather complex, technologically challenging infrastructure, which takes seconds to display a hopefully relevant ad.

And in this competitive sphere, Publishers are adding more and more SSPs to share their inventory with, SSPs are adding more and more publishers to get more commissions from the inventory, and the DSPs are adding more and more SSPs to make sure they can find the best ad recipients and prices there.

As you can imagine, all these components need to communicate with each other resulting in trillions of requests between each SSP and DSP every month. Lots of service resources, high traffic costs, and huge amounts of carbon emissions.

What is QPS anyway?

What is Query per second(QPS) Optimization?

What does QPS mean?

QPS is the number of information requests a service handles per second. Each one of the ad spots on the site usually has its own requests flying around to different SSPs, which then multiply them by the number of DSPs they are working with. Often resulting in hundreds of requests for a single ad placement. . And the truth is - there is a lot of “spam” in these requests, which most DSPs won’t buy.

Therefore, many DSPs enforce strict QPS limitations, meaning they provide each of their supply partners with a set budget of how many requests they may send per second.

Therefore, optimizing the QPS is vital to gain optimal results from the available budget. This technique has transformed common platforms into online giants as we know them today. Only through a sophisticated process can you show the right Ad to the right person at the right time.

What is the role played by QPS in this regard?

How does QPS Optimization work?

Real-time bidding technologies have seen a meteoric rise, especially since the pandemic. However, traffic also increased when people got more time staying home. This was stressful and challenging for the ad industry. It was evident when ad spending decreased. And now, with businesses going online worldwide, the traffic between the SSP and DSP has become a bottleneck, big time!

SSP players need more infrastructure to accommodate the multitude of requests coming in from publishers. This surge of traffic requires them to invest more in Cloud resources and increase expenses.

Next, coming to the receiving end.

DSPs get bombarded with requests from the supply-side, increasing their cloud costs without a change in revenue. This issue ultimately affects the partnerships they maintain with advertisers and agencies.

Some partnerships stipulate limited SSP queries to avoid network overload, making things even more challenging. For instance, 5,000 queries per second are all they are allowed to transmit to the DSP. The subsequent ones are ignored, leaving a potential piece of the pie on the table because there is no one to eat it.

But what if I tell you that you can eat your pie and still have it because there is a solution?

Now you know why optimizing the queries per second is pivotal for dynamic Ad campaigns and their revenue generation capability. So what is the solution, then?
