Every explorer in this group sells advertising and almost none of them publish what it costs — the standard answer to "how much is an Etherscan ad" is a contact form and a negotiation, which is why the question keeps getting asked and never answered. Every price on this page is the price. The search box is the single most-used element on a block explorer and the only placement in this catalogue that reaches someone at the exact moment of intent. A reader on an explorer is mid-task, technical, and about to look up an address, a transaction or a token — which is a state of attention almost nothing else here can reach, and one that rewards a recognisable name plus one concrete reason to click over any kind of argument.
Six explorers sell this format, covering Ethereum, Solana, BNB Chain, Polygon, Base and a multi-chain search engine, and several price it identically, which means the choice between them is almost entirely about which chain your users are on rather than what you can afford. Only one of the six publishes a click figure, so the rest are bought on position rather than on reported performance.
| 6 placements priced in EUR | €6,240 to €8,580. These are ad placements, priced against contracted impressions rather than the host site’s traffic, so there is no single cost per thousand to rank them by — each page states its own. |
A placement in the Solscan search field — the single most-used element on the Solana explorer, in front of seven million monthly visitors. Sold on CPM.
One week in the Etherscan search box — the single most-used element on the site. Reports roughly 2,100 clicks per week, one of the few placements here quoted in clicks rather than impressions.
A placement in the Bscscan search field — the box every BNB Chain lookup starts in, on an explorer with 2.5 million monthly visitors.
A placement in the Basescan search field — the explorer for Base, the chain that brought the largest wave of first-time on-chain users.
A placement in Blockchair’s universal search bar — the box people use to look up an address, a transaction or a block across more than a dozen chains.
A placement in the Polygonscan search field, reaching a million monthly visitors at the moment they look up a Polygon transaction.
The one your contract is deployed on. Several are identically priced, so chain fit is the only sensible criterion — and a genuinely multi-chain product loses nothing by buying more than one, because the audiences barely overlap.
One does, at roughly 2,100 a week. The rest publish nothing, and we do not estimate on a publisher’s behalf — each page says plainly which case it is.
Intent. A banner reaches someone who happens to be on the page; the search box reaches them at the moment they are doing the thing your product probably relates to.
