Arbitrage Glossary 2026: 50+ Terms (UBT, CPA, ROI, Hook Rate)
Why this glossary matters
Traffic arbitrage and performance marketing have their own jargon, blending English-language terms, ad-platform abbreviations, and industry slang. It's easy for a newcomer to get lost: some terms refer to traffic sources, others to performance metrics, others to technical anti-detect tools, and others to creative production. This glossary collects more than 45 real, widely used terms and groups them by category, so you can quickly find a definition, refresh your memory before a team call, or explain the basics to someone new to the field.
Traffic sources
Organic traffic (UBT) — visitors who reach a site or app without direct paid promotion, often through social media virality, recommendation algorithms, or unpaid content distribution.
Push notifications — an ad format where the offer arrives as a system-level notification on the user's device, typically after they've subscribed to a push traffic network.
Native ad — an ad format that visually and stylistically blends into the surrounding platform content, reducing the sense that it's an advertisement and often boosting CTR.
Landing page — a dedicated page that traffic is sent to, responsible for converting a visitor into a purchase, sign-up, or install.
Prelander — an intermediate page shown before the main landing page, used to warm up the user or filter out non-target traffic before the actual offer is shown.
Cloaking — a technique of showing different content to a platform's moderators versus real users, used to pass moderation for offers that technically violate platform policy.
Tracker — a service or script for tracking clicks, conversions, and attribution across traffic sources and campaigns; essential for understanding which channel actually drives results.
Monetization and payment models
CPA (cost per action) — a payment model where the advertiser pays for a specific user action, such as a sign-up, purchase, or app install.
CPM (cost per mille) — the cost per thousand ad impressions, regardless of clicks or conversions; common for reach-focused campaigns.
CPI (cost per install) — the cost of a single mobile app install, a key metric for mobile and gaming verticals.
CPC (cost per click) — the cost of a single click on an ad, a basic unit for evaluating traffic-buying efficiency.
EPC (earnings per click) — the average revenue generated per click on an affiliate link; a key metric for evaluating an offer's performance within a network.
Payout — the fixed amount an affiliate program pays out for a completed target action on a given offer.
In-app purchase — a payment made by a user inside a mobile app; an important monetization metric for mobile verticals and freemium apps.
Whitelist/blacklist (ad-account sense) — lists of allowed or blocked placements, domains, or publishers inside an ad account, controlling exactly where ads can run within a network.
Performance metrics
ROI (return on investment) — a profitability metric expressing the ratio of profit to invested funds as a percentage; a baseline metric for evaluating campaign profitability.
ROAS (return on ad spend) — the ratio of revenue generated by ads to the amount spent on them, a key metric for evaluating specific campaigns and creatives.
CTR (click-through rate) — the ratio of clicks to impressions, showing how appealing a creative is to the audience.
Hook rate — the share of viewers who keep watching a video past the first few seconds (commonly the 3-second mark), a critical metric for short-form video performance.
Retention — the share of users who keep using a product or watching content after a certain period following their first interaction.
LTV (lifetime value) — the total revenue generated by a single user or customer over their entire relationship with a product; important for evaluating an offer's long-term economics.
Churn — the share of users who stop using a product or cancel a subscription over a given period; high churn usually signals product issues or a poor audience fit.
Cohort — a group of users sharing a common trait (such as sign-up date or traffic source), analyzed separately to track metric trends over time.
A/B test — a method of comparing two versions of a creative, landing page, or offer by splitting traffic between them to statistically determine the better-performing variant.
Technical and anti-detect terms
Shadowban — a hidden restriction on an account's or content's visibility imposed by a platform without explicit notice, usually noticed as a sudden, unexplained drop in reach.
Multi-accounting — operating multiple accounts as a single person or team, typically to scale publishing volume, ad-auction bids, or offer testing.
Antidetect browser — a specialized browser that masks a device's digital fingerprint, allowing one operator to manage multiple accounts without the platform linking them by technical signals.
Proxy — an intermediary server that routes a user's traffic, changing the IP address and apparent geolocation seen by the platform.
Fingerprint — a unique digital signature of a device and browser (screen parameters, fonts, plugins, time zone, etc.) that platforms can use to identify and link accounts together.
GEO — the geographic market or country a campaign targets; the choice of GEO significantly affects both traffic cost and conversion rate.
Vertical — the industry or topic category of an offer, such as gambling, dating, nutra, finance, or e-commerce; different verticals require different creative and traffic approaches.
Creative and content terms
Creative — the ad material (video, image, or text) shown to users within a campaign, directly affecting CTR and hook rate.
Creative fatigue — declining ad performance caused by repeated exposure of the same creative to the same audience, usually showing up as falling CTR and rising CPA over time.
UGC (user-generated content) — content created by users, or styled to look user-generated, often perceived by audiences as more authentic than studio-produced ads.
Video variation — altering the technical and visual characteristics of content (video, audio, images) to avoid it being flagged as a duplicate by moderation systems and detection algorithms.
Spy tool — a service for analyzing competitors' ad campaigns, creatives, and offers to research the market and find working combinations.
Account warm-up — gradually building activity on a new account (follows, views, likes) before launching full-scale ad or content activity, to reduce the risk of a ban.
Split test — synonymous with an A/B test: dividing traffic between several creative or landing page variants to compare results on a real audience.
More terms worth knowing
Affiliate program — a referral compensation system where a partner earns a payout for referred customers or users, sometimes including a lifetime commission on their future payments.
Ad account — an account on an advertising platform used to launch, configure, and manage campaigns.
Bidding — the process of setting a bid for an impression or click within a platform's auction system, which affects how often and at what cost ads are shown.
Fraud — fraudulent traffic or activity that artificially generates clicks, impressions, or conversions without genuine user interest, distorting campaign statistics.
Source (traffic source) — the specific platform or channel traffic comes from — a social network, search engine, push network, native ad network, and so on.
Affiliate network — a platform connecting advertisers (offers) and partners (arbitrage buyers), which tracks conversions and distributes payouts among participants.
Conclusion
This glossary is a working reference, not an exhaustive list — arbitrage and SMM constantly generate new terms tied to specific platforms, formats, and tools. But the fundamentals — traffic sources, payment models, performance metrics, technical anti-detect terms, and creative production — remain a stable foundation for the profession, regardless of shifting trends and algorithms. Video variation, mentioned in this glossary, is technically implemented by tools such as 360 Uniquizer, with its 19 video effects, 13 audio effects, multi-threaded processing, and built-in uniqueness check — one of the practical pieces that turn many of these terms into something you can actually apply rather than just theory.
