Get Similarweb competitors and similar sites

Read a website's competitors / similar sites from its public Similarweb overview page: competitor domain, affinity percent, category and category rank. No login required. Returns the ~10 competitors the anonymous page renders; the section's "See all competitors" expander leads to gated Similarweb product pages, so that is the anonymous ceiling. available:false means Similarweb has no report for that domain.

Input

domain required

Website domain, e.g. "spotify.com" or "notion.so". A full URL or a leading www. is accepted and normalised to the bare host.

Output

domain required

The normalised domain the report was requested for.

available required

False when Similarweb has no report for this domain (it redirects to /website/ with no domain segment) — an expected outcome for small or unknown sites, not an error.

competitors required

Empty array is a legitimate outcome: available:false, or a report whose competitors section renders no rows.

competitorCount required

Number of competitors returned — how many the anonymous page rendered, not the total Similarweb knows.
