Coinzilla

Coinzilla is the network most crypto publishers and crypto-native projects end up using — and that is not by accident. Founded in 2016 out of Sevio Advertising Technology, it has slowly become the de facto incumbent in crypto advertising on the strength of a deep marketplace, on-time payments, and a moderation process strict enough to count as a feature rather than a bug.

What Coinzilla actually is

A European, regulated, crypto-first ad network with quiet expansion into finance — its banners now show up on sites like investing.com and stocktwits.com alongside the obvious crypto-vertical inventory: CoinMarketCap, Etherscan, DEXTools, Blockchain.com. It runs a self-serve platform with optional account managers on both sides, a bidding-based pricing engine, and a marketplace for everything that does not fit programmatically — press releases, sponsored articles, newsletter inclusions, KOL posts, social campaigns.

Two things to flag up front. First, it is crypto and adjacent finance only on the publisher side; for advertisers the lane runs slightly wider — crypto, finance, and iGaming brands are all served. If you are not in one of those lanes, none of what follows applies to you. Second, it is European, which means real invoices, real KYC and KYB, and real compliance posture. That cuts both ways — we will get to where it cuts later.

For publishers

What it actually takes to get in

The traffic minimum gets too much attention. Like most networks — AdSense very much included — Coinzilla does not publish a number; in practice, sites with roughly 500 daily users and up start clearing the basic bar. But the real review is not a traffic counter:

• Content quality — unique, edited, not AI-spun filler.
• Design and current ad load — a manager will eyeball your existing placements before approving more. Coinzilla prefers clean zones with real visibility over banner-stuffed pages.
• Traffic sources — your analytics tell them one story, their own tools tell them another, and a manager may ask you to fill in the gap.
• Niche — crypto, with some flexibility into finance. Anything outside that range gets rejected, full stop.

If you are approved, ad review on individual creatives runs around 24 hours.

Formats worth running

Stick with the standard sizes: 300×250, 728×90, 320×100. They are easy to integrate, every advertiser uses them, and they will give you the best fill and the best eCPM. Static, GIF, and HTML5 are all accepted. Native ads work where they fit your layout.

The exception is pop-unders. Those are not for premium publishers. They are meant for incentivized inventory — faucets, paid-to-click sites, reward apps — where the audience tolerates the interruption because they are there for the cents anyway. On a real editorial site, pop-unders will cost you more trust than they earn you in revenue.

What the money actually looks like

The platform is bidding-based, so there is no fixed rate card. In practice, per-banner eCPMs cluster around €3 baseline and push to €6–7 when a publisher is genuinely fought over — known site, sticky audience, geos that convert, conversions that close. None of this is guaranteed; geos, conversions, exposure, and brand pull all move the number.

That figure is per banner, not per page. Page-level RPM scales with how many placements you run, and Coinzilla’s preference for clean, high-visibility zones means you are not stuffing eight units onto a page to multiply the number — you are running fewer placements that each earn more. Done well, that math comes out ahead.

Versus the alternatives, on the publisher side

• AdSense has softened its stance on crypto recently, but rejections are still common for both publishers and advertisers, and even when you do get in the rates are some of the lowest in the market unless you happen to sit on a high-demand niche site.
• Bitmedia is older and busier with new launches, but it is hard to find a serious crypto publisher running it exclusively. Mostly visible on incentivized inventory, with much of the rest pulled in via SSP integrations.
• Cointraffic was the biggest crypto network at one point. It has been slowly bleeding share to Coinzilla, largely on the strength of higher rates and better terms.
• A-Ads is older still, but on a network-wide unique-impression model: the same user across ten sites is paid for once. Combined with an inventory that includes everything from porn to illegal streaming to cooking blogs, neither advertisers (poor targeting) nor publishers (low effective payout) tend to come out ahead.

For a serious crypto publisher, the realistic answer is Coinzilla or building a direct sales team. For most sites that lack the resources for the latter, that is not really a choice.

For advertisers

How the platform works

Self-serve at its core: create an account, verify it, build your campaign, get it approved. A solid review process sits in front of every campaign — necessary in a market where fake-domain scams are routine and impersonation is constant. An account manager comes included, not as an upsell. They will suggest campaign tweaks, help with the review process, and act as an extension of your team if you want them to.

Bidding is built in. As you set up a campaign, the platform shows you the recommended or highest current CPM for your targeting — useful even if you ultimately decide to bid below it. If you would rather buy on a fixed price, the marketplace carries fixed-price banner, native, and high-impact placements.

Targeting — classic, on purpose

Geo, website, zone, device, frequency capping. No aggressive data collection, no Google-style behavioural surveillance — crypto audiences notice and do not appreciate it. The depth is in the inventory (premium placements on names like CoinMarketCap, Etherscan, DEXTools), not in cookie-grade tracking.

RTB — and where Coinzilla shows up beyond itself

The whole platform is bidding-native, so RTB integration is how Coinzilla extends its reach. The clearest example: investing.com runs its own ad-tech stack internally, and Coinzilla is a bidder into that stack — meaning a campaign you build inside Coinzilla can land on investing.com’s premium traffic without you ever leaving the Coinzilla dashboard. The same pattern repeats across other premium finance and crypto inventory.

Web3 retargeting

Retargeting is not a new idea anywhere else on the internet, but in crypto it has been awkward — the integrations and the data agreements simply were not there. Coinzilla has done the work: a user who visits a crypto product page, hesitates, and leaves can be brought back with a relevant ad through the network. Most users do not convert on the first or second visit, so for advertisers this is one of the more measurable features the platform offers.

The marketplace

Beyond display, the marketplace is where Coinzilla earns its position. It is the place to buy — or, as a publisher, to sell — everything that does not go through programmatic: press releases, sponsored articles, newsletter slots, social posts, KOL placements, on sites and from voices that actually matter in crypto. Match the format to the goal:

• Awareness — social posts, newsletters, PRs.
• Search and AI visibility — articles and list inclusions on known sites; anything that drives organic discovery.
• Direct performance — display and native on premium inventory, high-impact placements when budget allows.

Crypto casinos and betting brands

One segment worth calling out: iGaming. Crypto casinos, sportsbooks, and betting brands are locked out of Google and Meta almost everywhere — and Coinzilla serves them, subject to the same strict compliance review as everyone else. For that segment this is the first network to try, not the fallback: the premium crypto inventory is exactly where a risk-tolerant, transaction-ready audience already spends its time, and the marketplace side (PRs, KOLs, newsletters) covers the awareness gap that display alone cannot close for a casino brand.

The honest section

Non-refundable deposits — what is actually going on

This is the gripe that shows up loudest in advertiser reviews, and it is the one that most needs context. Coinzilla accepts crypto. A crypto deposit refunded back out is exactly the pattern AML regulators flag as money laundering, and a European company under European rules is not going to invent a process that exposes it. The non-refundable rule is a compliance fence, not a money grab. The alternative would be a refund flow with source-of-funds questions, legal letters, and bank statements — which is what users would actually like even less.

The practical implication for an advertiser is simple: do not deposit big on day one. Start with a small test budget, get comfortable with the platform, build a working relationship with your account manager, then commit budget you actually want at stake. Treating the first deposit as a feeler rather than a war chest avoids the entire problem.

Traffic quality and bots

Some bot exposure is unavoidable on the open internet — that is true everywhere, not unique to Coinzilla and not unique to crypto. Coinzilla’s position is that its detection layer filters invalid traffic before it bills you, and any bot impressions that do show up in your own analytics were not charged. They are not — and no honest ad network is — going to publish exactly how the filtering works, because the people gaming traffic also read those posts.

The realistic advice: if you are running pop-under or incentivized-traffic campaigns specifically (which is a buy you make for cheap exposure, not direct conversion), expect the traffic to look messier in your dashboards even if billing is clean. On premium display and native, the picture is normal-for-the-industry.

What costs them the point on the score

The opacity around publisher requirements. Every network does this — even AdSense does not publish a hard threshold — but in a market where small publishers are deciding whether to even apply, the absence of even ballpark guidance pushes good sites away unnecessarily. It is one of the easier things to fix and one of the only structural improvements I would ask for.

Trustpilot and what it actually means

Trustpilot has them at roughly 3.5/5 across ~100 reviews. That is a useful sentiment thermometer, not a verdict — and most of the negative reviews trace back to the two issues above (refund policy, traffic quality on cheap campaigns) being misread as bad-faith behaviour rather than the structural choices they actually are.

One unrelated scam warning

There is an active impersonation scam — emails offering a fake “Coinzilla Desktop App” from non-corporate addresses. It is not Coinzilla. Do not install anything that did not come from inside your dashboard.

Verdict

A 9/10. Coinzilla is the closest thing crypto advertising has to a default — older than most, more regulated than most, more responsive than most, with the deepest marketplace in the niche. The single point off is for the unpublished publisher requirements, which is industry-standard but still avoidable.

Use Coinzilla if you are

• An established crypto or crypto-adjacent finance publisher looking for a serious revenue line.
• A crypto or Web3 project that wants real placement on the inventory that actually matters — and is willing to start small on the first deposit.
• An advertiser who values an included account manager and a real self-serve platform over a black-box managed buy.

Skip Coinzilla if you are

• A general or mainstream content site — you will not be approved.
• A brand-new crypto blog still building traffic — come back when you have it.
• An advertiser expecting Google-Ads-style refund flexibility — you will not get it, for legal reasons.

There is not really a serious alternative in the crypto-vertical category. The only honest competitor for a large publisher is a direct sales team, which most sites do not have the resources or the market stability to build. Until that changes, Coinzilla is the answer.
