HilltopAds

HilltopAds is a popunder ad network with direct publisher supply, a plain self-serve panel and weekly automatic payouts. Buyers get depth in dating, iGaming, streaming and app installs. Site owners get a traffic monetisation platform with anti-adblock delivery. 

We keep an account funded here for one reason. Pop volume that scales without the panel arguing back.

That is not the same as saying everything checks out. We found a rate card that does not exist anywhere on the site, a support desk that goes home on Friday, and two counters on their own advertiser page that disagree with each other by a factor of a hundred.

So below is the full write-up. How the buying side feels, what the selling side actually pays, and the handful of places where we would push back before wiring money across.

One thing we'd flag on the entity side. A registered UK company with two published phone lines and a physical address is not nothing in an industry where half the pop networks are a Telegram handle and a Capitalist wallet. It doesn't make the traffic good. It does mean there's somebody to invoice.

Ad formats and which side of the platform sells each one

Six formats plus one publisher only link product. The split between buy side and sell side matters more than people expect, because two of the most interesting products can only be sold, never bought.

Format	Available to	Buying models	What we noticed
Popunder	Advertisers and publishers	CPM, CPA Goal	The main event. No creative to upload, just a landing page, which is why a new campaign goes live in minutes
In-Page	Advertisers and publishers	CPM, CPC	Push style notification look without a subscriber base behind it, so no list decay and no opt in prompt
Video VAST	Advertisers and publishers	CPM, CPC	Pre-roll, mid-roll and post-roll, with a configurable skip delay. Best fit for streaming and download inventory
Video Slider	Advertisers and publishers	CPM, CPC	Small player that slides into a corner of the page, less intrusive than a pop and cheaper than in-stream
Banner	Advertisers and publishers	CPC	The weakest product here. One documented size on the format page, 300×250, and a second size listed elsewhere on the same site
MultiTag	Publishers only	Revenue share	Rotates In-Page plus Popup, Banner plus Popup, or Video Slider plus Popup from a single tag and picks whichever earns more
Direct Link	Publishers only	Revenue share	A single URL for social, messenger and link in bio traffic, with no site required

The gap on this list is subscriber push. Plenty of buyers still want an aged push base for retargeting style volume, and HilltopAds doesn't sell one. In-page covers part of the job and none of the list building.

Buying models and how bidding actually plays out

Four ways to buy, and they are not interchangeable.

Now the complaint. There is no public bid floor, no rate card, and no GEO price list anywhere on the site. Not in the blog, not in the help pages, not on the advertiser pages.

Practically, that means the first hour of every new campaign is a discovery exercise. We open with a mid bid, watch delivery for thirty minutes, then step it up or down until impressions move.

That's a normal enough habit for experienced buyers. For someone spending their first $100, it's a tax on inexperience, and a published range per tier would fix it.

What we do instead

Inside the panel, targeting depth that beats most pop networks

This is where HilltopAds earns most of its score. The targeting set is closer to what a push network offers than what a pop network usually bothers with.

Targeting layer	Options available	Why we use it
Geography	Country, plus city level for the United States	US city targeting makes local sweeps and service offers viable instead of a national money burn
Language	Browser language	Separates the right audience inside multilingual GEOs, which country targeting alone never does
Browser	Browser and specific version	Version level filtering kills the ancient browsers that convert on nothing
Operating platform	OS and OS version	App install offers usually need a floor version, and this enforces it before spend
Device	Type and brand	Brand targeting matters on pin submit and app offers where payouts skew by handset
Network	Mobile carrier, connection type, ISP	Carrier billing offers need carrier targeting to work at all, and wifi versus mobile changes everything on video
Address	IP range	Handy for excluding known bad blocks or isolating a corporate audience
Applications	Installed applications	The one we did not expect on a pop network, and the most interesting for app and utility verticals

Automatic Optimization, the feature we actually rely on

Set the rules once and the platform blacklists zones that fail your thresholds. On a pop campaign with thousands of sources, this is the difference between a profitable week and a manual zone review every night.

It's not clever enough to scale winners, only to cut losers. We still whitelist manually once a campaign has a week of data behind it.

Proxy and WebView filter

Two switches, both worth flipping on day one. The proxy filter drops traffic arriving through anonymising layers. The WebView filter drops in-app browser sessions, which look like mobile web but behave nothing like it.

Our experience on sweeps was blunt. With WebView left on, volume dropped visibly and quality went up enough that we stopped noticing the volume.

Fully managed as an alternative to self serve

There's a managed option where the team builds and runs campaigns for you. It's genuinely useful for buyers moving into an unfamiliar vertical, and it's also how a lot of the bid range knowledge stays inside the company rather than on the website.

API access and tracker connections

The API covers GET, POST, PUT, PATCH and DELETE, so campaign creation, edits, bid changes and stats pulls are all scriptable. The key is generated inside My Account under the API tab, and the documentation lives on the blog under the API docs tag rather than in a separate developer portal.

That last part is a small annoyance. Docs published as blog posts are harder to keep current than versioned documentation, and we'd rather have a proper reference page.

On tracking, s2s postback tracking is standard and the usual suspects plug in without drama.

Tracker	Typical fit
Voluum	Cloud tracking for teams that want zero server maintenance
Binom	Self hosted speed, popular with high volume pop buyers
Keitaro	Self hosted with heavy filtering rules
BeMob	Free tier that suits a first campaign
RedTrack	Multi channel setups where pops sit next to paid social
PeerClick	Straightforward affiliate tracking
AdsBridge	Built in landing page editor
AppsFlyer	Mobile attribution for app install campaigns

Partner integrations reach further than trackers. AdKernel and AdSpyglass sit on the ad serving side, Mobidea on the affiliate side, and the advertiser roster includes names like Hotspot Shield, AliExpress, Lazada and Shopee.

For a publisher deciding whether the demand pool is mainstream enough to sit on a family friendly site, that list is more informative than any fill rate promise.

Money in, money out, and the mismatch nobody mentions

Advertisers fund a prepaid balance. Publishers get paid automatically. Both sides are straightforward until the payment method lists stop agreeing with each other.

Method	Advertiser deposits	Publisher withdrawals
Capitalist	Yes	Yes
USDT TRC20 and ERC20	Yes	Yes
Bitcoin	Yes	Yes
Wire transfer	Yes	Yes
Paxum	Yes	Yes
Wise	Yes	Yes
Credit card	Yes	No
Union Pay	Yes	No
PayPal	Listed on the homepage, absent from the advertiser page	Yes
WebMoney	Listed on the homepage, absent from the advertiser page	Yes

So the homepage counts ten deposit options while the advertiser page counts eight, and the two missing ones are exactly the two that publishers can withdraw with. Not a scandal. Just sloppy, and the kind of thing that costs a support ticket when somebody plans a top up around PayPal.

Invoices are available for both companies and individuals, which matters more than it sounds. Plenty of pop networks still cannot produce a document an accountant will accept.

Promo code terms

The code AFFNINJA adds a 20% bonus on top of a deposit. Two things we'd check before relying on it. Apply it at the moment of the top up rather than after, and confirm with the manager whether the bonus portion is spendable across every format or restricted, because bonus credit rules vary by network and this one isn't spelled out on the page.

The publisher side, where MultiTag does the heavy lifting

We put two sites on the sell side to see how it behaves. Verification is done by uploading a file or dropping a meta tag, the same as most SEO tools, and it took a couple of minutes.

Payments land automatically every Tuesday on Net7 terms once the balance passes $20. Weekly is genuinely good. The $20 floor is the part that stings a brand new site, because week one earnings on a small blog rarely clear it and the money just sits.

Where HilltopAds falls short

No softening here, because these are the reasons we still split the budget across other networks.

HilltopAds vs Adsterra vs Clickadu

Three networks we've had money in. The comparison is not flattering everywhere.

FAQs about HilltopAds

Final word

HilltopAds is a good pop network with a bad habit of hiding information that would make it an easier one to recommend. The targeting depth genuinely beats most of its peers, MultiTag is the cleanest publisher product in this bracket, and weekly automatic payouts are the sort of thing you only appreciate after a network has made you chase an invoice.

Against that sit the missing rate guidance, the weekday only support, the absent subscriber push and a banner product that reads like it was built to complete a list. None of those are dealbreakers for buyers who already know how to price a GEO. All of them are friction for someone arriving new.

Our position after using both sides of it is simple. Keep it funded, run pops and in-page through it, blacklist hard in the first forty eight hours, and don't plan a big launch for a Saturday.
