Autonomous media buying,
defined.

The vocabulary of the category, in plain language. Kerdixo is the AI operator for affiliate media buying, and these are the terms it operates by: each one defined so it stands alone. The most category-defining terms get a full page of their own.

The category

01 Autonomous media buying

Autonomous media buying is the practice of letting software run paid ad campaigns end to end, from choosing what to run through launching, monitoring performance, and reallocating budget, while humans set the boundaries instead of executing the tasks. It differs from platform automation, which optimizes delivery inside a single campaign. Kerdixo is an autonomous media buying operator for affiliate marketing on Meta and TikTok, always inside human-approved guardrails. Full definition →

02 Agentic media buying

Agentic media buying is media buying performed by an AI agent that pursues a goal across many decisions rather than executing single commands: ranking options, launching, monitoring, adjusting. It is a near-synonym of autonomous media buying: agentic emphasizes the software doing the work, autonomous emphasizes the mode of operation. Kerdixo is an agentic media buyer with a human-approved boundary around every action. Full definition →

03 AI media buying agent

An AI media buying agent is software that runs paid ad campaigns autonomously: choosing what to run, launching, monitoring performance, and reallocating budget. Kerdixo is an AI media buying agent built for affiliate marketing on Meta and TikTok, with human-approved guardrails around every action. Full definition →

04 Affiliate media buying

Affiliate media buying is buying paid traffic to promote offers on a performance basis: the affiliate funds the ads and earns when conversions happen. Because the affiliate carries the capital and the risk, the decisions around the campaign matter as much as the ads themselves: which offer to run, when to refresh, when to stop. Kerdixo is built specifically for this discipline, not for generic brand advertising. Full definition →

05 Media-buying loop

The media-buying loop is the recurring cycle of work around a paid campaign: rank offers, prepare creative, launch, watch performance, enforce limits, measure outcomes, and move budget. Kerdixo automates the full loop on Meta and TikTok, from launch to creative refresh to portfolio movement, inside the guardrails you set.

06 Portfolio operator

A portfolio operator is an affiliate or team running many campaigns across multiple ad accounts and platforms, managed as one book rather than as isolated campaigns. Meta sees Meta and TikTok sees TikTok; Kerdixo is built to see the portfolio and move budget to where the whole book earns it.

Control & trust

07 Shadow mode

Shadow mode is a propose-only operating mode for autonomous systems: the software runs its full decision loop but executes nothing without human approval. Shadow is Kerdixo's default. The operator proposes every move; you approve, edit, or override, and every override teaches it your bar. Full definition →

08 Full Auto

Full Auto is an operating mode in which an autonomous system executes decisions without per-action approval, inside limits agreed in advance. In Kerdixo, Full Auto is earned per campaign when Shadow-mode overrides stay low, is restricted to the guardrails you approved, and reverts to Shadow instantly.

09 Guardrails

Guardrails are hard limits a human sets around an autonomous system's actions: budget caps, CPA ceilings, spend-velocity rules, learning-phase protection. In Kerdixo, actions outside the approved guardrails are blocked or sent for review. The safety layer does not negotiate. Full definition →

10 Shadow override rate

The Shadow override rate is the share of an autonomous operator's proposals that a human rejects or edits before execution. A falling rate means the operator's proposals increasingly match what the human would have done anyway. Kerdixo treats it as the test of trust: campaigns earn Full Auto when overrides stay low.

11 Accountability gap

The accountability gap is the distance between what an autonomous system does with your money and what you can verify it actually did. Kerdixo's thesis is that this gap must be closed twice: for the customer, through Shadow mode and guardrails; for the market, through a public live dashboard of learning, guardrail events, and incident history.

12 CPA ceiling

A CPA ceiling is a hard upper limit on cost per acquisition: the most a buyer will pay for one conversion. In Kerdixo it is a guardrail, set per campaign and approved by you. Actions that would breach the ceiling are blocked before execution.

The loop's decisions

13 Offer ranking

Offer ranking is scoring the offers an affiliate could run by how well each one fits a specific buyer and market, so capital goes to the best next test instead of the loudest promotion. Kerdixo ranks offers for your profile, geo, platform, budget tier, and creative maturity, and shows why each one fits. Approvals, rejections, and measured outcomes improve the next ranking.

14 Budget reallocation

Budget reallocation is moving spend from weaker positions to stronger ones. In-platform tools reallocate inside one campaign; the harder version crosses campaigns, ad accounts, and platforms. Kerdixo treats offers, platforms, and accounts as one portfolio and recommends safe moves: from tired to fresh, capped to open, decaying to emerging.

15 Creative fatigue

Creative fatigue is the decline in ad performance that comes from an audience seeing the same assets too often. The hard call is telling tired creative apart from an exhausted market, because the two look identical from inside a campaign and demand opposite responses. Kerdixo watches creative health against broader market patterns to make that distinction.

16 Creative refresh

A creative refresh replaces or rotates ad assets before fatigue erodes performance. Kerdixo builds and refreshes compliant creative libraries from market patterns and privacy-safe network signals; its creative intelligence uses abstract style patterns and aggregate outcomes only, and your actual creative assets are never shared with other affiliates.

17 Learning phase

The learning phase is the period after a campaign launches or changes significantly, while the ad platform's delivery system is still calibrating and performance data is noisy. Premature edits during this window waste the calibration. Kerdixo's guardrails include learning-phase protection: spend velocity is capped and premature actions are blocked or sent for review.

18 Lifecycle decision

A lifecycle decision is the call on what a campaign or offer deserves next: hold, scale, refresh, or move on. Offer lifecycle sits outside the ad platform view entirely. Kerdixo watches offer health across affiliates and campaigns, distinguishes normal learning from real weakening, and checks each call later against the outcome it produced.

The landscape

19 In-auction optimization

In-auction optimization is the automated delivery optimization ad platforms run inside a campaign: bids, audiences, placements. Meta Advantage+ and TikTok Smart+ are the reference examples. It is good at its job, and it ends at the campaign's edge. Kerdixo does not replace it: the platforms run the auction, and Kerdixo runs the decisions around it.

20 Operating memory

Operating memory is the accumulated record of an operator's decisions and their measured outcomes: which offers converted for which profiles, which refreshes worked, which lifecycle calls proved right. It is the part of an autonomous system that cannot be coded, only earned. The agent is the easy part; Kerdixo's operating data takes years to build and cannot be bought.

21 Agent economy

The agent economy is the emerging market in which software agents transact with other software agents, including brands that integrate through agents rather than dashboards. In that market, counterparties select on verifiable properties, starting with provenance: prove where the traffic came from. Kerdixo's public dashboard and per-decision receipts are built for that world.
