II's search traffic has fallen 47% since September 2025 (25,476 to 13,480 visits a month, Ahrefs) as the pages Google ranks fell 84%. Its 90+ events are largely missing from Google's AI answers and the conference calendars they quote. This models what fixing that, plus retargeting II's own visitors and a LinkedIn test, is worth in new manager memberships. Only the 21% manager share of readers is II's own figure; every other rate is a placeholder until II's numbers replace it.
Ads alone: ~16 new members. With search & AI answers: ~21 on the same ad budget.
Yellow is what search and AI answers add on the same ad budget.
A year of visits and ad clicks at the rates set above. Ads are aimed at managers, so every ad click counts as a manager click. Only the 21% manager share is II's own figure.

First-year membership revenue a year. Every other rate as set above; the yellow cell matches the current setting.
| Ad budget a year | £120,000 |
| Ad clicks a year | 26,667 |
| New members from ads | 16.0 |
| Revenue per £1 of ads | £3.33 |
| Ad cost per new member | £7,500 |
Search & AI add ~4.8 members on the same ad budget.
For scale: the same 8,000 search visits a month would cost ~£9,325 a month in Google Ads at ~£1.17 a click (Ahrefs' value per visit). Search also reaches what ads can't: AI answers and the event calendars.
Each month without the plan defers ~£43K of first-year membership revenue. II's search traffic is down 11,996 visits a month since September 2025 (−47%) and has fallen every month since June 2026 (Ahrefs). At the 12-month trend (−36%), another year takes ~4,800 more visits a month off search, worth ~£73K a year at these rates.
