HOW THEY DIFFER
The short version.
On our benchmark Semrush takes the higher overall GEO Score (83 to 81) — but that headline hides where each one really pulls ahead.
On reach, OmniSEO is ahead — 9 of 10 engines versus 5. If the engines your buyers use aren't covered, the rest barely matters.
On price, OmniSEO starts lower — $89/mo against $99/mo — though the cheaper sticker isn't always the better deal once coverage is in.
In short, OmniSEO suits mid-market/agency/ecommerce teams; Semrush leans toward mid-market/agency/enterprise.
