Otterly is a lightweight monitoring dashboard — you get a chart and a to-do list. SiteSonar detects the gaps, writes the fix, publishes it to your site, and re-verifies the citation lift.
Otterly is a great budget monitor for teams that just want to see where they stand. If you need the platform to actually move the number — write pages, publish them, and prove the lift — you'll outgrow Otterly the first month you try to act on a report.
Otterly Lite starts at $29/mo (~15 prompts). SiteSonar starts at the Growth tier at $499/mo and includes GEO Autopilot, publishing, the Website Assistant, visitor ID, and CRM sync. Different category, different outcome.
