Webinar tooling is a capacity question first and a feature question second. Buyers arrive at a comparison page knowing roughly how many attendees they need to host, whether they need automated registration funnels, whether they need on-demand recordings, and whether they need a paid-ticketing layer. The relevant numbers (max attendees, max simultaneous events, recording retention windows) sit on the vendor pricing pages and they drift between billing cycles.

SleekRank reads one matrix with platform slug, starting price, attendee cap at the entry tier, recording quality, registration features, and a focus tag. Each row drives the per-platform page and every pair the platform appears in. Tag mappings push attendee caps into the hero, list mappings render registration features into a checklist, and selector mappings inject the recording note into the comparison block.

When Zoom Events resizes its registration tier or Demio adjusts the seat cap on its starter plan, you edit the row and flush the cache. The corpus catches up. Adding Riverside Studios to a corpus that already covers Zoom, GoTo, Demio, and Livestorm is one row plus the four pair pages it multiplies into, not five fresh head-to-heads written by hand.

Webinar tooling is a price-per-attendee question, and the per-attendee math drifts every billing cycle. Zoom Events restructures its event pricing, Demio adjusts seat caps on the starter tier, Livestorm tweaks the registration landing experience, GoTo bundles features differently. The buyer who arrives at a webinar platform comparison page is usually thinking about a specific webinar (a launch event for two hundred attendees, a weekly office hour for fifty, a paid masterclass for fifteen) and the answer they need is whether the platform fits at that scale.

A page that shows last year's attendee cap is worse than no page at all because the buyer clicks through, finds the discrepancy at the vendor, and bounces. Webinar affiliate revenue depends on that click converting at the vendor, so trust on the page is paid trust. The freshness problem also affects registration features.

Vendors ship registration upgrades on irregular cadences (Demio added new question types, Livestorm reworked the post-registration flow, Zoom Events added registration analytics), and pages that miss those updates look stale to buyers who already saw the change announced. SleekRank does not solve research; it solves the propagation, so the cell you edit on Tuesday is reflected on every per-platform and pair page by Wednesday's cache cycle.
