# 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.

## Run it

Ask an AI agent connected to Reduck over MCP (`https://mcp.reduck.ai/mcp`) to run `reduck/similarweb.com/get_competitors`, or run it from a terminal:

```bash
npx @reduck-ai/cli@latest run --script reduck/similarweb.com/get_competitors
```

## Input

- `domain` (string, 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` (string, required): The normalised domain the report was requested for.
- `available` (boolean, 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` (array, required): Empty array is a legitimate outcome: available:false, or a report whose competitors section renders no rows.
- `competitorCount` (integer, required): Number of competitors returned — how many the anonymous page rendered, not the total Similarweb knows.
