After 30% of the time, 21% of the impression goal should have been reached. After 50% of the time, 50% of the goal should have been reached. And after 70% of the time, 79% of the goal should have been reached.

Open Ad Exchange
In open ad exchanges, all advertisers have an equal opportunity to buy (either manually or programmatically) available ad inventory from publishers via an open auction. This contrasts with private marketplaces where publishers control who can access the exchange and participate in the auction. Publishers use open ad exchanges to sell remnant ad inventory at a low cost. There is no pre-agreed relationship between either party, and publishers can choose to withhold information, so the advertiser may not know which specific placements they are buying. For publishers, the low prices may be offset by advantages such as a large pool of buyers, the potential for high-volume sales, and the opportunity to generate revenue from inventory that may otherwise go unsold.

Optimization
The process of making adjustments to campaigns, content, or strategies to improve performance. In commerce media, optimization involves refining targeting, bidding, and creative elements to achieve better results.

Out-Stream Ads
Out-stream ads are video ads that play ‘out-stream’, i.e. outside of streaming online video content. They are video ads that appear in non-video text-based editorial content/articles or on social media feeds.

Appearing in various formats, including “in-text” or “in-swipe”, the ads typically play without sound, giving the user the option to unmute the ad. Publishers can offer out-stream ad placements even if their site doesn’t feature their own video content, allowing them to monetise more pages.

Advertising that reaches consumers while they are outside their homes, typically through billboards, transit ads, and other outdoor media.

Over-the-top (OTT)
Term used to describe both a type of content and the devices used to deliver content directly to users via the open internet. OTT delivery differs from IPTV delivery – both use the internet, but IPTV services use a privately managed content delivery network and OTT services use the open internet, the same as used for email and web browsing. OTT devices, which connect the viewing device to the internet, include smart TVs, smartphones, game consoles, and streaming devices such as Roku, Chromecast, Apple TV, or Firestick. OTT devices pull content from the internet at the request of the viewer, delivering it via specific apps in one single stream as VOD (video on demand), SVOD (subscription-based video on demand), or live content. Services such as Netflix and Amazon Prime are classed as OTT content providers – with a subscription, users can stream SVOD content via apps on their OTT device.

Online Video (OLV)
OLV is a video ad format commonly referred to in reference to video advertising on web and mobile app devices (as opposed to Connected TV devices).

P

Pay-Per-Click (PPC)
An online advertising model where advertisers pay a fee each time their ad is clicked. It is commonly used in search engine advertising and display ads to drive traffic to a website.

Programmatic Mediation
A platform that allows media owners (typically app developers) to plug in multiple demand sources (historically ad networks) to compete for their inventory, usually in a waterfall setup.

Pixel
A small piece of code placed on a website that tracks user behavior, often used for retargeting and measuring the effectiveness of ads in commerce media networks.

Pixel Stuffing
A type of ad impression fraud where one or more ads are served in a display unit as small as 1×1 pixel. Although the ad server records it as an impression, the ad is too tiny to be seen or interacted with by users, meaning the advertiser pays for impressions that don't provide actual visibility or engagement.

Post-Roll
Post-roll video ads play immediately after a publisher’s video content. They are effective for encouraging viewers to take immediate action, as they don't interrupt the main content. Post-roll ads are available across various devices, including desktop, tablet, mobile, and smart TVs.

Privacy Mesh solutions often use techniques like anonymization and data aggregation to ensure that user information is not personally identifiable, thus supporting privacy compliance while facilitating effective advertising and analytics.

Premium Ad Inventory
Ad inventory that is considered to be of high quality and is therefore valued at a higher price.

Pre-Roll
Pre-roll video ads play just before the publisher's content begins.

Pre-roll ads are available on desktop, tablet, mobile, and smart TVs.

Potential Reach
Use algorithms to optimize for greatest reach by impression and provides the number of users you could reach with your targeting selection.

The use of automated systems to buy and sell ad inventory in real-time, often through auctions. This technology is foundational to commerce media networks for efficiently managing large-scale ad campaigns.

Publisher
An individual or organization that creates and distributes content, such as websites or apps, where ads can be displayed. In commerce media, publishers are key partners in delivering ads to targeted audiences.

Private Marketplace
A private marketplace (PMP) is a controlled ad exchange where a publisher selectively invites advertisers or demand-side platforms (DSPs) to participate in closed auctions. The publisher sets terms like minimum pricing (floor pricing) for each participant. Unlike open ad exchanges, which are accessible to all advertisers, PMPs offer more exclusive and controlled access. Smartclip operates exclusively on a private marketplace basis. See also: Invitation-Only Auction, Open Ad Exchange.

Programmatic Guaranteed Deal
A programmatic guaranteed deal is a direct, one-to-one agreement between an advertiser and a publisher where both parties pre-agree on the number of impressions and the price. The advertiser commits to purchasing a specific number of impressions at a fixed price, and the publisher guarantees the delivery of those impressions. On platforms like smartx, the buyer sets minimal configurations, as delivery and targeting are managed on the publisher's side. The SSP applies the pre-agreed terms, including CPM, pacing, frequency capping, and targeting, ensuring the agreed impressions are delivered. Programmatic guaranteed deals are one of three types of programmatic direct deals on the smartx platform, alongside direct deals and direct guaranteed deals.

Purchase Behavior
Market segmentation of website traffic or CRM data that provides analytics on interest-to-buy, intent-to-buy, and past-purchase trends in online and offline purchases, why they purchase, and where.

It includes both 'linked' information (like names and addresses) and 'linkable' information (such as place of birth or religion) that can identify someone when combined with other data. PII is crucial in US privacy law, while the EU's GDPR uses the broader term 'personal data' to cover a wider range of information.

Q

A metric used by search engines and ad platforms to evaluate the relevance and quality of an ad, keyword, or landing page. In commerce media, a higher quality score can lead to better ad placements and lower costs.

Quantitative Data
Data that can be measured and quantified, such as clicks, impressions, or sales. In commerce media, quantitative data is essential for analyzing campaign performance and making data-driven decisions.

Queries Per Second (QPS)
Queries per second (QPS) measures the number of requests a server receives each second. It is commonly used to assess the traffic and capacity of information retrieval systems like search engines or databases. In digital advertising, high QPS indicates that an ad network or exchange can handle significant demand, reflecting both its reach and ability to serve large volumes of ad requests.

R

Reach
The total number of unique users who are exposed to a particular ad or campaign. In commerce media networks, maximizing reach while maintaining relevance is crucial for campaign success.

Remarketing

Reserved Inventory
Reserved inventory refers to specific ad space on a website that is set aside exclusively for certain advertisers based on a pre-agreed deal or price. This type of inventory is often used in programmatic guaranteed deals, where ads are served automatically according to the terms of the deal. Advertisers may reserve inventory to secure premium positions, run time-sensitive campaigns, or ensure their ads are displayed alongside particular content.
