From Similarweb, export the competitors you track and the keywords you monitor as CSV.
Create your workspace, add your primary domain and competitor domains.
Projects → Competitors → Import CSV. SERP-derived share of voice recomputes automatically against live SERP data.
Rank Tracker → New → Import keywords CSV. Daily checks start immediately.
Confirm the keyword universe against your Similarweb export. SEMOptimiser Gap adds SERP overlap that Similarweb does not surface.
If panel-derived market share and DMI are core to your board reporting, keep a Similarweb seat. If SEO intel is the sole use case, cancel.
