# Similarweb

> Get website traffic estimates, global rankings, and competitor discovery.

[Similarweb](https://www.similarweb.com) is a leading source of digital market
intelligence. It models the traffic and engagement of millions of websites and
apps, covering estimated visits, traffic sources, audience demographics, and the
competitive set around any domain.

Attach `similarweb` to an [Exa Agent](/docs/agent/quickstart) run through
[Exa Connect](/docs/agent/connect/overview), and the agent queries
Similarweb alongside Exa web search.

## Use it for

* Benchmarking a company's web traffic and engagement against its peers.
* Mapping a domain's competitors and audience-overlapping sites.
* Sizing markets and screening companies by digital footprint.
* Enriching company and category research with real behavioral data.

## Provider ID

Use this value in `dataSources`:

```text theme={null}
similarweb
```

## Example

Find 10 fast-growing B2B SaaS companies and their estimated web traffic.
