The main differentiator is programmatic fills otherwise vacant inventory with audience/intent/etc placements and is not purchased through the publisher directly. To get to the definition you have to go back before ad networks existed. Companies owned a website, and you went to the 'ad sales' section of the website and negotiated packages with the company. You'd get ads placed for a limited amount of time and/or impressions, and the purchase was similar to what you'd do for a Newspaper or Print ad today. Then came ad networks. Publishers could add them in to give eyeballs to remanent inventory. Say they had 1 million visitors in a day, but only sold 500k impressions directly. The ad networks pick up the other 500k for the highest bidder (and the publisher makes more money). The networks started directly placing buys themselves, but quickly realized they could automate it to optimize performance for both advertisers and publishers - and thus multi-site and programmatic advertising was born. An advertisers could now say "get me as many impressions as you can for under $3 CPM" and the networks could go out across tens of thousands of sites, enter auctions, and deliver. After that, layering on third-party data, intent, etc. was just the natural evolution of ad network buys. So to that point, you can have a buy on the same site and one can be 'programmatic' and one cannot. I can buy direct from CNN.com for 1 million impressions. That's not a programmatic buy. I have selected exactly where I want the ads to serve and can negotiate if I want homepage, politics, etc. placement. I can also buy through an ad network, and when CNN has remnant inventory (inventory that has not been purchased direct) it will serve up in the auction, allowing it to get auctioned and placed by those various networks to the highest bidder. I can set preferences, whitelist placements, etc. but I'm not guaranteed to serve unless remnant inventory becomes available on those placements AND I want win the auction to get placed. The first is not a programmatic buy. The second is. Google search is not a programmatic buy because you are buying on a specific site (Google) with specific terms/phrases/etc. that you are directly negotiating with Google (within the platform). Google display is a programmatic buy because it runs on an ad network that fills remnant inventory across millions of publishers, but you are having no direct negotiations with said publishers. Youtube, purchased through Google ads platform, is not a programmatic buy because you have selected the broader site and are instead running on channels within it. If you run a digital video campaign through Trade Desk or another vendor, and YouTube is one of the channels available in the targeting set along with a hundred other OTT or streaming app networks, then it could be a programmatic buy. Basically programmatic refers to specifically how the inventory is getting placed (direct vs. through a network). The audience targeting, intent, etc. are all part of programmatic platforms but don't inform the definition. Answer from OddProjectsCo on reddit.com

There are very few situations when programmatic display is a good idea... Change my mind
There’s a lot to unpack here but one thing I will say is that “prog display is full of unseen ads, bots, fraud, crappy 3rd party data” is definitely an outdated opinion, assuming you’re using a half decent agency to run your campaigns. I use DV/IAS pre and post bid on all my campaigns so have absolutely no issues with fraud, bots etc and from experience it’s incredibly easy to spot if there are any potential flags, even without DV/IAS. I also haven’t used 3rd party data in over 2 years and barely even done so before then. There are a few decent providers e.g. Nielsen, Bluekai etc. but I tend to stick with 2PD such as Google, Amazon & publisher owned data, as well as contextual targeting. I think a very large part of what you’re referring to will actually be down to what inventory you’re serving on. I choose to serve on quality and well known publishers via OMP, PMP & PG where viewability and other metrics tend to be pretty decent. If you’re serving on absolute crap websites and just overlaying a random audience layer then yes I agree this is potentially a badly run campaign. In terms of awareness/performance, display can be used as both. High impact/large ENGAGING banners can be a great way of getting your message in front of users, particularly in the right environment. Not to mention all of the rich media formats such as skins, scrollers etc. Performance wise, I think it can entirely depend on what you’re product is, yes display isn’t going to be perfect for every single vertical but you absolutely cannot ignore the impact that it does have on user journeys, any analytical source can show you that and to assume that a user is going to see one social/OOH/TV ad and convert/become brand loyal is absolutely bonkers. IMO display does have a place on most campaign plans but you really need to look at its role and how it can work alongside and strengthen other channels, there’s really no point in comparing it to social/PPC/OOH as it’s purpose and benefits are completely different.

Display: Dv360 vs Google Ads
I feel like you have some fundamental understandings of how programmatic tech stacks work to catch up on. Not judging, just pointing out that this question is sort of... I mean they're not really the same thing. GDN/Google Ads is an end to end display buying system, trading ease for control and performance. DV360 is a full DSP, intended to be part of a larger tech stack. It offers significantly more control, significantly more inventory sources, the ability to manage deals, etc. More on reddit.com

r/PPC on Reddit: Confused by 'Programmatic' Digitla Advertising vs. 'Non-Programmatic' Digital Advertising?
August 11, 2024 -

Hi all, I am having a hard time understanding what 'programmatic' digital advertising actually is, and how it is different from non-programmatic digital advertising?

My ad stack is 6sense display ads, Youtube video, Google paid search, and FB and LI ads.

Every single one of the above ad channels runs ads dynamically based on the target audience, their level of intent, and where they are currently in the marketing funnel.

Given the dynamic nature of pretty much all ad platforms in 2024, I am really confused what the definition of 'programmatic' advertising is.

I see online 1 definition of programmatic advertising is "Programmatic advertising refers to the practice of automating media buying and creating digital ads with the use of marketing technology"

Since all ad platforms I use automate media buying, is the only difference between programmatic if the ads are created dynamically using these platforms, vs non programmatic would be using static ads?

Thanks.

6Sense Display would be the only platform you mentioned that is "programmatic" in your stack. The other platforms will only serve on the respective sites, based on your targeting parameters, whereas 6Sense sense can serve on any one of their partner sites/networks and uses precise targeting to segment audiences with real data and in near-real time (RTB).
