Although search and social are still central to marketing strategies everywhere, the cost of solely depending on these channels has become more alarming. With a greater focus on brand safety, user privacy, and data security, marketers are feeling more pressure to spend in spaces where they have greater control. This article offers some steps to help you escape the walled gardens.
Why the Walled Garden Math is Getting Harder to Ignore
Meta and Google became very successful by providing excellent markets for their customers and giving them quantifiable results. For some time, the formula was easy: invest your money, get customers. This model still holds up, yet the margins are smaller.
Apple’s App Tracking Transparency update led to the tracking of the source of lots of Meta mobile campaigns to get messed up. Facebook lost the ability to optimize for conversions as iOS users began to opt out of tracking, and the cost per action increased. Simultaneously more marketers entered into the same auction-based systems and almost every one of those bid floors went up. The same users are oversaturated in a sense: they’ve seen enough ads that performance on new ads drops quicker than it did. You get creative fatigue on even smaller audience exposures, which means refresh cycles and production costs rise, and plateaued on reach.
The shift is structural. Google and Meta’s combined US digital ad market share dropped to 48.4% for the first time in almost a decade (Insider Intelligence), and that cash is flowing directly into retail media, programmatic, and independent ad networks. This isn’t a prediction, it’s an observed trend at large scale already.
It’s no longer a question of if you should diversify, but rather how to do it without falling into traffic channels that only waste money.
How Independent Ad Networks Actually Work
Walled gardens like Facebook and Google own and control everything on the inside of their ecosystem, the audience data, the inventory, the measurement, the rules. Independent ad networks act like connectors between you, the advertiser, and thousands of publishers: blogs, utility sites, streaming and file-sharing services, browser extensions, wallpaper and recipe sites, message and bulletin boards, fan fiction and image hosting, news aggregators, and more.
When you buy through an ad network outside of the walled gardens, you’re buying inventory that doesn’t exist inside a social feed. These are people engaging with content or checking out tools or browsing topics that happen to overlap with your offer, not scrolling past ads in their timeline. The most advanced targeting available is often contextual, device or geo, or behavioral segments based on the publisher’s first-party data, none of the cross-app tracking that Apple’s recent iOS updates have degraded.
In return, this traffic requires more setup than you may be used to with Facebook or Google. You probably won’t get very far by just clicking “Boost Post”. You need to have the right kind of tracking already set up on your site, a funnel that you’ve qualified that’s ready to receive these visitors, and the patience to optimize against your own conversion data rather than letting the platform do the measuring. But for an enterprising growth marketer willing to lay that kind of groundwork, the CPA potential on these networks is still considerably better than what most search and social campaigns are probably hitting at scale.
Native Ads For Mid-Funnel Engagement
Native ads are very similar to what walled gardens are good at and spread out across independent publisher inventory instead of algorithmic feeds.
A native ad is similar to editorial content, a recommended article, a story, a sponsored post that matches the page’s visual design. This is important because the ad doesn’t reveal itself similar to a banner or a pre-roll ad. Banner blindness is a real thing. People who browse the web long enough tend to filter out rectangular ad units. Native placements don’t activate that filter.
Which is where native ads perform best, the middle of the funnel; the people are aware of a problem or a category but not a specific solution. An advertorial explaining the mechanism of a product, a comparison piece, a listicle-building context. These work because they aren’t asking before giving.
The distribution logic is different as well. When buying native ads traffic via an established independent network, you’re spreading the content out at scale across relevant publishers. But you’re not allowing a social network to decide which users will view it. You’re making that decision based on audience categories, geo segments, device types. And that affects neither the publisher’s revenue nor your campaign’s performance.
One last note, native traffic is cold, these aren’t users that searched for you, or were retargeted from a previous visit. And your ad won’t convert them into buyers right away. The ad works as a content entry point. An advertorial pre-lander is almost always necessary.
Push Ads and the Viewability Advantage
Push notification ads are simple. A user agrees to receive notifications from a website, and that notification subscription is used to deliver an advertisement. With a push campaign, your ad is served directly to the user’s device screen, either a desktop or a mobile device, in the form of a notification containing a headline, snippet, and image.
The viewability argument is quite simple. The ad renders outside the browser. This means it dodges most ad blockers while also being served in an environment that a user can’t simply scroll past or otherwise ignore, as they might a sponsored feed unit on a webpage. It can be very effective at driving higher click rates than typical display formats, particularly for campaigns with a short window, since the time-sensitive nature drives urgency within the audience.
Push is a good format for time-limited offers, finance/insurance offers with urgency drives, re-targeting users with previous demonstrated interest within a campaign over a full category of inventory, and app installs. It isn’t a good format for products where the user needs to be educated on the need for the product prior to a click. They can be great at generating a high level of interest within users to obtain a click, but may generate lower qualified leads due to the simplified nature of the user’s decision-making process.
Different from social, push subscribers opted in to receive notifications. They have a baseline level of receptivity/interest, but they did not opt into your offer. As a result, conversion from click to outcome will depend almost entirely on the landing page the user arrived at on click. The higher the click-through rate, the wider your audience, and therefore the more variant the landing page view, the lower the conversion rate will become at traffic scale. The title, image, and targeting are all table stakes for creating a push ad that will perform.
Popunder Placements and Volume-Based Acquisition
Popunder ads are advertisements that open a new browser window behind the current active window of a user’s device. These ads open the window when the user is interacting with a website page and sees an ad on the page. Once the user minimizes the active window or closes it, they will see the ad behind the active window that’s been hidden. It’s essential to understand that popunder ads aren’t prime real-estate ad placements. They serve a different purpose of driving more massive amounts of traffic to a site if you play your cards right.
Popunders typically cost less than other types of traffic, and with good reason. Converting popunder traffic is more challenging than other sources. That being said, if your goal is volume, put a strong focus on your lead generation funnel converting enough low-cost contacts into lucrative customers, popunder traffic can deliver quantities beyond search and social. This type of ad traffic is usually less expensive than many other types of website traffic. Finding the right popunder ads network can bring you tons of visitors at a much lower price than search or social, often for a small fraction of a cent per visitor.
If you can live with a less qualified visitor as that volume base, you can often work out a cost-per-action that is profitable when competing for search/network and social traffic is not. The cost per acquisition (CPA) with a properly run popunder campaign can beat out search and social conversion prices. Some results have been seen with a conversion cost that could be only a tenth of competitive traffic.
Pre-Landers: The Conversion Bridge You Can’t Skip
From native, push, pop, and the like, if there’s one thing campaigns that fail to convert always leave out, it’s the pre-lander. The pre-lander (short for pre-landing page) is an intermediary page between the ad click and the final offer. Its job is to warm up and qualify your traffic so that when they do arrive at the offer page, they’re not making an instant, chilly yes-or-no decision.
You need a pre-lander because without one, your ad clicker has only an ad to go on. That ad is battling for attention among a sea of other ads in the native content feed, push/pre-pop notification, or whichever other channel you’re working. They might not remember the ad three seconds after they clicked it. The pre-lander solves that problem by letting you give them more: more context, more information, more of a reason to convert.
Efficient pre-landers come in different shapes depending on the nature of your offer. A quiz or self-assessment to warm the user up and prep the offer page by segmenting the reader and personalizing their experience. An advertorial to tell the problem-solution-story before introducing your product as the solution. A comparison page to deal your product against your competitors’. These different types can do wildly different things, sure, but what they all have in common is that warming-you-up function.
Tracking Without Social Pixels
Using tracking links allows you to append different UTM values to the end of each link so you can later identify which placements are working the best. This is the first step in analyzing the results of your campaign. You need different links for every different combination of the five UTM values so the tracker can tell exactly what drove the action.
Without S2S tracking through a campaign tracker, you’ll end up manually checking and comparing numbers. It’s a ton of data entry and spreadsheet work, and you won’t get all the numbers because clicks and conversions are under-reported (sometimes being reported at fractions of what they actually are) and it’s hit or miss as to which actions can be attributed and which can’t.
S2S postback tracking through a tracker isn’t simple to set up. You most likely need a developer to configure your server, but the good news is once you do have it, you maintain the ability to directly compare ad network-reported numbers with the tracker’s for quality assurance. As involved as it is, this is an indispensable tool for accurate tracking and optimization on the open web.
Operational Resilience Through Diversification
Relying on one or two platforms for the majority of your paid acquisition is a risk that people tend not to talk about until it’s too late. Ad account suspensions are immediate and unappealable, no matter the lost revenue. Algorithm and policy changes can cause average CPAs to rise 40%, until you can’t afford to bid for the users you need anymore. A small change in eligibility in one of the platforms, that alerted them to a non-compliant piece of ad creative, was enough to send their business into a death spiral.
But one doesn’t have to wait until they’re entirely dependent on search and social to start diversifying their spend. The real draw is budget spread across native networks, push campaigns, and popunder inventory operating independently of any single platform’s decisions. If one channel goes down, the other two keep giving you traffic and conversions. Or at least that revenue continuity.
The practical approach is to start with 15% to 20% of total ad spend allocated to open-web channels while the tracking and funnel infrastructure is built and tested. As performance data accumulates and optimization identifies what converts, that allocation can grow. The goal isn’t to abandon search and social, it’s to stop being entirely dependent on them.
