E.ON.
On the unbranded question the comparison portals and the city utility capture the query.
Found & recommended by AI agents
Search-class agents touched the close in some runs; the full agent-fleet access profile lands in a later wave.
This page measures the commerce lane: can an agent find E.ON, and once it arrives, transact. Talent, after-sales, procurement, investor and press lanes run on different surfaces and are not yet measured.
Your brand isn't measured yet
What does an AI agent do with your website?
The same measurement as E.ON, free for your domain. Five agent classes, one real task, your score in 48 hours.
Portals own the unbranded query. The surface lets only the strongest agents through.
We asked five kinds of AI agent to reach a switch-ready state for an E.ON electricity tariff (3,500 kWh, postcode 80331) on eon.de. A coding agent read the €975.23 Strom Basistarif. A plain HTTP fetch was blocked at the door by a Cloudflare WAF. A standard browser agent could not target the postcode combobox in any of three runs. The autonomous agent found a different path, the Anbieterwechsel flow, and reached the contract form (step 2 of 3, E.ON ÖkoStrom Pro Extra 24, new-customer bonus €287) without authentication, by operating the postcode field directly. The provider switch is fully initiable; the calculator is the wall.
One label, many breeds. From a plain reader to an autonomous operator, the kinds behind ChatGPT, Perplexity, and Claude Code:
Blocked somewhere on the path: Plain reader, Computer-use agent. A customer whose assistant runs on one of those breeds never finishes the task.
Scope. This is one tariff in one postcode. E.ON spans electricity, gas, solar, heat pumps, and EV charging, each with its own calculator and switching flow.
Found, and able to transact?
Two questions, measured separately. A brand can be recommended and still un-buyable, or perfectly buyable and never found.
When someone asks an agent to switch to a tariff, does it route to E.ON?
E.ON comes up about a quarter of the time. The rest of the time, an agent recommends an alternative first.
Discoverability · 18-datapoint auditOnce an agent is on E.ON's site, can it complete the switch?
Search-class agents surface contract-form-ready in some runs; the full agent-fleet access profile lands in a later wave.
Evidence · 70 / 100 A measure of how provable and consistent the result is, grounded in cross-method ground-truth agreement (the methods that ran returned the same price), not a separate measured run. A confidence layer on the two scores above, not a third sales axis.
What this means for E.ON.
On product discovery, E.ON is not failing to exist; it is failing to be the answer. The unbranded energy question routes to the city utility and the comparison portals, and the surface that would convert a found customer blocks the plain reader and the standard browser. E.ON is found late and completed by few.
Make the surface answer the unbranded question and admit every agent class. Agent-readable tariff and switching surfaces a plain fetch and a standard browser can complete, not only the most capable scripted agent, and citeable evidence the answer engines can name directly instead of routing to a portal.
The proof is not a faster calculator. It is agents of every class completing the switch on E.ON's own surface, and the unbranded question naming E.ON, re-measured each wave.

Energy comparison sites capture 56% of tariff demand before E.ON.
Across the 18 Gate-1 responses, 56% routed the Munich electricity question through a comparison portal (Verivox in 6, Check24 in 5, Stromauskunft in 3); eon.de appeared directly in only 3. The capture is heaviest on the unbranded informational query, where 5 of 6 responses sent the user to a portal. The comparison portals own the energy-switching question before eon.de is reached. (The Munich city utility also surfaces unbranded, but as a competitor on discovery, not as a displacing channel.)

E.ON Strom Basistarif (Anbieterwechsel)
- Close state
- contract-form-ready
- Bottleneck
- Coding agent reads the €975.23 tariff; a plain fetch is WAF-blocked and a standard browser cannot operate the postcode field. Only the autonomous agent, by operating the postcode field directly, reaches the contract form. Unbranded discovery routes to portals and the city utility.
Fairness note
Wave 3 (a fleet wave Telecom & Utilities). Single measured task (Strom Basistarif, 3.500 kWh, PLZ 80331, contract_form_ready close state via Anbieterwechsel). AI Visibility 26.28 (18/18 valid datapoints across 3 providers, unbranded informational); AI Usability derived from the a fleet wave access profile. Channel split grounded via channel-derive.py (intermediary in 10/18 Gate-1 responses). Confidence C, single task; Fairness Review pending the sector fairness grid.
How the score was produced.
Discoverability is audit-pipeline-derived. 3-provider sample (openai, perplexity, anthropic), 3 query variants per task, 2 runs per variant · 18 valid datapoints scored against a five-state handoff cascade. [S1]
AI Usability is derived from the access-profile above (usability-derivation/v1): how far the best agent reached (close state) modulated by how many agent classes succeeded. The per-class profile is the truth; the score is a reproducible summary of it, not a separate rating. Fleet phases (HTTP / Coding / Browser / ACT) produce the profile. [S2]
Agent Success Score = (AI Visibility × 0.20) + (AI Usability × 0.70) + (Evidence × 0.10)
On a 0–100 scale, displayed 0–10. AI Usability bundles the agent's reach + completion; AI Visibility is audit-derived discoverability. Weighting is public; the per-prompt derivation is not.
Measurement scope
Confidence C · one measured task on a 3-provider track (openai, perplexity, anthropic). Confidence promotes to B with a second task plus a fourth provider on the next wave.
