What it does
Similarweb Traffic is an agent skill from OpenClaudia/openclaudia-skills. Fetch website traffic estimates (monthly visits, traffic sources, top countries, keywords, engagement, ranks) for any domain from SimilarWeb. Use when the user asks about a domain's traffic, monthly visits, traffic sources, audience countries, or wants to compare/benchmark sites against competitors.
Its SKILL.md is about 880 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/fetch-similarweb-traffic.js`).
The repository describes itself as: 77 open-source marketing skills for Claude Code, Codex, and other AI coding agents. SEO, content, email, ads, analytics, and growth. The licence is MIT.
When your agent uses it
- The user asks about a domains traffic
- Traffic sources
- Audience countries
- Wants to compare/benchmark sites against competitors
Example prompts
- “/similarweb-traffic”
Requirements
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit ad0d1e5. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (JavaScript), which the agent can run.
Shell commands in SKILL.md call:
nodenpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
data.similarweb.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Similarweb Traffic loads about 882 tokens when it runs. Until then it costs about 80 tokens; SKILL.md has 335 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

- similarweb-traffic
- description
- Fetch website traffic estimates (monthly visits, traffic sources, top countries, keywords, engagement, ranks) for any domain from SimilarWeb. Use when the user asks about a domain's traffic, monthly visits, traffic sources, audience countries, or wants to compare/benchmark sites against competitors.
SimilarWeb Traffic
Fetch traffic-overview estimates for any domain — monthly visits, traffic-source breakdown, top countries, top keywords, engagement metrics, and global/category ranks.
When to Use This Skill
Use this skill when the user:
- Asks how much traffic a domain gets ("what's the traffic for X")
- Wants monthly visit trends for a site
- Needs a traffic-source breakdown (organic vs direct vs paid vs GenAI, etc.)
- Wants to know a site's audience countries
- Wants to compare/benchmark several domains against each other or competitors
Usage
No API key required. Self-contained Node script (uses built-in fetch, no npm install).
node scripts/fetch-similarweb-traffic.js <domain>Examples:
# Formatted markdown summary (default)
node scripts/fetch-similarweb-traffic.js chatslide.ai
# Raw normalized JSON (for further processing / comparisons)
node scripts/fetch-similarweb-traffic.js stripe.com --jsonThe domain can be passed bare (example.com) or as a URL (https://www.example.com/pricing) — it gets normalized (strips scheme, www., and path).
Comparing multiple domains
Run the script once per domain with --json and combine the results into a table. Add a short delay between calls to be polite to the endpoint.
Output
Default mode prints a markdown summary: a metrics table (monthly visits, ranks, bounce, pages/visit, time on site), a monthly-visits trend line, traffic-source breakdown, top countries, and top keywords.
--json mode prints a normalized object:
{
"domain": "stripe.com",
"globalRank": 327,
"categoryRank": 21,
"category": "Finance",
"snapshotMonth": "2026-05",
"visits": 122394040,
"bounceRate": 0.55,
"pagesPerVisit": 3.26,
"timeOnSite": 165.9,
"estimatedMonthlyVisits": [{ "date": "2026-03-01", "visits": 118067753 }],
"trafficSources": { "searchOrganic": 0.48, "direct": 0.23, "...": 0 },
"topCountries": [{ "countryCode": "US", "value": 0.087 }],
"topKeywords": ["..."]
}visits is the most recent complete month. Rates (bounceRate, all trafficSources, topCountries[].value) are 0–1 fractions.
API Details
- Endpoint:
https://data.similarweb.com/api/v1/data?domain=<domain>— SimilarWeb's undocumented public data endpoint (the one their browser extension uses). No auth, no key, free. - Requires a browser
user-agentheader (the script sends one) — defaultcurl/bot agents are blocked. - Synchronous, returns immediately.
Important Notes
- Estimates, not ground truth. SimilarWeb models traffic; numbers can be off, especially for mid/low-traffic sites. For a domain you own, your own Google Analytics / Search Console data is authoritative — prefer those when available.
- Unknown domains return zeros, not an error. SimilarWeb responds HTTP 200 with all-zero/synthetic data when it has no data for a domain. If every visit count is 0, treat it as "no SimilarWeb data."
- Unofficial endpoint. It can be rate-limited, change shape, or require auth without notice; this is a gray-area use of SimilarWeb's data outside their paid API.
- Exit codes:
2network error,3non-200 HTTP response.
