Glossary

Ad-tech language, without the jargon.

Every term you will meet in the console, explained the way we would explain it to a first-time publisher.

Impression: One banner request that was successfully filled and rendered on a publisher page. On NexusAd, one impression served for someone else earns you one credit.
Credit: The network's unit of exchange. Earn one by displaying a banner, spend one to have your own banner displayed elsewhere.
Click-through rate (CTR): Clicks divided by impressions, shown as a percentage. A healthy display CTR is usually well under one percent.
Fill rate: The share of banner requests that returned an ad. Low fill rate usually means no eligible campaign matched the size or the advertiser pool ran out of credits.
Viewability: Whether a rendered banner actually entered the visitor's viewport. A banner far below the fold may render without ever being seen.
Creative: The image or HTML5 file shown to visitors, together with its destination URL, format and schedule.
Format / size: The pixel dimensions of a placement, such as 728x90 leaderboard or 300x250 medium rectangle. Campaign and placement sizes must match.
Frequency capping: A limit on how many times the same visitor sees the same creative within a period, protecting both performance and visitor experience.
Daily cap / pacing: The maximum credits a campaign may spend in a single day, spreading delivery evenly instead of exhausting the balance at once.
House ad: A network-owned fallback banner shown when no member campaign is eligible, so the placement never renders empty.
Publisher key: The unique identifier in your ad snippet that attributes every served impression and earned credit to your account.
Site verification: Proving you control a domain by installing a meta tag or file, which unlocks earning and protects against key theft.
Above the fold: The part of a page visible without scrolling. Placements here typically deliver higher viewability.
Reciprocal network: An exchange where every participant is both supply and demand — you host banners to earn the right to have yours hosted.
Blocklist: Categories or competitor domains you refuse to display on your site, or sites you refuse to advertise on.
Invalid traffic: Impressions generated by bots, iframe stacking, auto-refresh or self-clicking. Detected activity is removed and can suspend an account.
