How we grade them

2.2GPAOmniSEOFair2.0GPASimilarwebFair
Value for money
BEssentials is $89 a month billed monthly with 5 seats, so a team of five pays a price per head inside the cheaper quarter of SEO tools. One marketer on their own pays the full $89, past the dearer quarter. Gemini, Claude and the other engines need Professional at $349.
DGraded against the suites it's listed beside. Competitive Intelligence is $125 a month billed yearly ($199 monthly) for 1 user, with traffic data but no SEO tools. That's dearer than Semrush's SEO plan, and keyword research, rank tracking and audits start at $333.
Free plan and trial
CNo free plan, but a 7-day free trial with no credit card. It only covers ChatGPT and Google AI Overviews, and a week is just about enough to see where you stand.
CThe free version on similarweb.com and the free browser extension show a high-level sample of any site's traffic and keywords. Good for a quick look, not for real work. There's also a 7-day trial of the self-service plans.
Features
CVisibility scores, prompt research with query volume, citation tracking, benchmarks against 5 competitors, sentiment and next steps. It does AI visibility fully, but that's a smaller job: no Google rank tracking, site audit or backlink tools on any plan.
CTraffic and engagement estimates, demographics and channel mix for any site, with SEO, AI and ad intelligence on dearer plans. Things the suites don't do, but the $125 plan has no SEO tools, and other sites' figures are estimates, not their analytics.
Ease of use
CNo App Store rating on record. You choose the prompts to save, capped at 50 on Essentials, and the competitors to track before the scores tell you much, so there's some setting up.
CNo rating on record. Typing in a domain is simple, but the platform is big, and reading traffic estimates and channel splits takes some learning.
Platforms and integrations
CWeb only, with no integrations or API on record, and Essentials has no CSV or PDF exports. Your numbers stay inside OmniSEO unless you pay for Professional.
BWeb plus a free extension for Chrome, Edge, Firefox and Opera. It connects to Looker Studio, Excel, Salesforce, HubSpot, Snowflake, Tableau and Power BI, but only on business packages with API access. No desktop or phone app.
