Put ads on your website.

Sign in to the network portal as a webmaster, add your website, create ad slots, then paste one snippet per slot into your pages. Each valid ad shown on your site earns credits you can spend on your own banners. See how the exchange works.

Get a webmaster account

Create an account as a webmaster (or both) and verify your email, then sign in. If an operator already made your login, go straight to sign in.
Add the website

Open Websites and choose Add website. Enter a name and the primary domain (for example example.com, no https:// needed). Localhost, bare IPs, and preview hosts are rejected. Pick the site type (general or gambling) and confirm the site has no adult content. The site starts as pending review, and ads start showing once an operator approves it.
Create an ad slot

Open the site and choose Add ad slot. Name the slot (for example Homepage header) and pick its main banner size. To make the slot responsive, tick more sizes under More sizes. Optionally show the "Ads by Signal" label. Use one slot per ad position on the page. See responsive slots.
Copy the embed code

On the site page, each slot has its own snippet. Choose Copy embed. You can copy and install embed codes while the site is still pending review. The placement key in the snippet is the only public identifier. Do not edit it.
Paste into your page

Paste the snippet once where the ad should appear (theme, CMS block, or template). Use one snippet per slot. Serve the page over HTTPS on an approved domain.
Check delivery and credits

Ads appear once the site is approved and an active campaign has an approved banner in one of the slot's sizes. See campaign basics. Each valid ad shown on your site earns credits, added every hour, and Home shows your credits and starter bonus progress. Home and Websites show ads shown, fill rate, empty slots, actually seen, and seen rate. The site page breaks them down per slot.
Block banners you do not want

The site page lists Banners shown on this site. Choose Block banner to stop one banner, or Block advertiser to stop every banner from that advertiser. Blocked ads never serve on that site. To undo a block, choose Unblock in the Blocked list.

Responsive slots

Create one slot for each ad position on the page, then add more sizes to it. A header slot can hold 970x250, 728x90, and 300x250, for example.
When the page loads, the embed measures the width the slot has, and Signal serves the largest of the slot's sizes that fits. If no banner is available in that size, Signal tries the next smaller size that fits. If the space is narrower than every size, Signal serves the narrowest size and scales it down to fit.
Paste the slot's one snippet. Do not paste one snippet per size, and do not switch snippets with your own script by screen width.
Signal picks the size once, at page load. Rotating a phone or resizing the window after that keeps the same ad.
Reserve at least the height of the slot's smallest size in your layout so the page does not jump when the ad loads.
To change a slot's sizes later, open the site and press Edit slot. The embed code does not change, so there is nothing to re-paste; pages that already have it show the new sizes on their next load.

If a slot stays empty

Check the site status. Pending and rejected sites do not serve ads.
Check that the snippet is on the live HTTPS page and that the host matches an approved domain for the site.
An empty slot can mean no eligible campaign has a banner in that size. Campaigns never serve on a site that matches their click URL domain, and banners you blocked are skipped. Your own campaigns for other websites can fill your slots unless you block them; those shows earn no credits.
To keep your own campaigns off one of your websites, open it in the portal and press Block my campaigns here in the Blocked panel.
Test in a clean browser or on another device if you use an ad blocker or privacy extension.
