Competitor Keywords API: every keyword any domain ranks for on Google, with position, traffic and the keyword gap

See every keyword a competitor ranks for on Google, without a Semrush or Ahrefs account: its position, the page that ranks, the estimated traffic each keyword brings and what that traffic would cost in ads, plus monthly search volume, CPC, keyword difficulty and search intent, in 92 countries. The keywords bringing the most traffic come first.

Add your own domain and each row shows your position beside theirs, with gap true where you do not rank: the keyword gap, ready to turn into a content plan. Built for SEO teams and agencies, content marketers, PPC managers and AI agents that want this per keyword instead of per seat.

What you get

Keyword rows	domain, keyword, position, previousPosition, movement (new, up, down), url, pageTitle, estimatedTraffic, trafficValueUsd, searchVolume, cpc, competition, keywordDifficulty, intent, monthlySearches, serpFeatures, rankedAt, country, language

2. Optionally add your domain for the keyword gap, and pick the country.
3. Click Start.

Output

Each result is one row in the run's dataset (download it as JSON, CSV, Excel, XML or HTML, or read it through the API). An example row (values shortened):

{
  "domain": "example.com",
  "keyword": "best robot vacuum",
  "position": 3,
  "previousPosition": 5,
  "movement": "up",
  "url": "https://example.com/robot-vacuums",
  "estimatedTraffic": 1240.5,
  "trafficValueUsd": 1860.75,
  "searchVolume": 14800,
  "cpc": 1.5,
  "keywordDifficulty": 38,
  "intent": "commercial",
  "yourPosition": null,
  "gap": true,
  "country": "US",
  "language": "en"
}

A record named SUMMARY in the run's key-value store says what each input returned, with any notes (for example an account that does not exist), what was charged and how much traffic the run used.

Pricing

• $0.001 per keyword row ($1 per 1,000)
• $0.04 per lookup: one request of up to 1,000 keywords, and a second per 1,000 when you add your own domain
• Domains with no rankings are free, and so are failed requests
• Apify's $0.00005 start charge counts towards your Maximum cost per run.

What typical jobs cost at the list price:

Job	Cost
100 keywords for one domain	$0.14
500 keywords for one domain	$0.54
500 keywords with your keyword gap	$0.58
5,000 keywords for one domain	$5.20

On Apify's Scale and Business plans the per-event prices are lower (Store discounts). Set Maximum cost per run and the Actor stops cleanly when it is reached: you never pay more than that.

Tips

• Most traffic comes first, so a small limit still shows what matters most.
• Add a worst position of 10 to see only the first page.
• Use the country where your customers search: rankings differ a lot by country.

Use it through the API

Python

from apify_client import ApifyClient

client = ApifyClient("<YOUR_APIFY_TOKEN>")
run = client.actor("zaiq/competitor-keywords").call(run_input={"domains": ["example.com"], "country": "US"})
for row in client.dataset(run.default_dataset_id).iterate_items():
    print(row)

JavaScript

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: '<YOUR_APIFY_TOKEN>' });
const run = await client.actor('zaiq/competitor-keywords').call({"domains": ["example.com"], "country": "US"});
const { items } = await client.dataset(run.defaultDatasetId).listItems();

HTTP (one call, results back)

curl -X POST 'https://api.apify.com/v2/acts/zaiq~competitor-keywords/run-sync-get-dataset-items?token=<YOUR_APIFY_TOKEN>' \
  -H 'Content-Type: application/json' \
  -d '{"domains": ["example.com"], "country": "US"}'

Integrations and schedules

• Schedules: run it every hour, day or week from the Apify Console (Schedules) and keep a history of results.
• Make, Zapier, n8n, Google Sheets, Slack, Airtable: connect it through Apify's integrations, or send each finished run to a webhook.
• Datasets: results stay in the run's dataset; export them or read them by API whenever you need them.

Use it with AI agents (MCP)

Add Apify's MCP server with this Actor already pinned (https://mcp.apify.com?tools=zaiq/competitor-keywords) to Claude, ChatGPT, Cursor, VS Code or any MCP client. The agent can find this Actor and run it for you: ask it for "the keywords this competitor ranks for on the first page that we do not". AI agents can also pay for runs directly through Apify's agentic payments.

Limits

• Rankings come from the data provider's database, not a live check for this run. Each keyword is rechecked on its own schedule, so a row can be weeks or months old (in our check some were 2 to 3 months old): rankedAt shows when.
• Google gives close variants one combined volume, so a page ranking for a plural can show the volume of the whole word, and estimated traffic can run high on very broad words. Compare sites with each other rather than reading a figure as exact visits.
• Estimated traffic comes from each keyword's searches and position, for Google search only, not all visits.
• Apify's free plan: one domain and 10 keywords, without your own domain.

FAQ

Do I need a Semrush or Ahrefs account?

No.

What is the keyword gap?

Keywords a competitor ranks for where your domain does not rank at all. Add your domain and each row says so.

How is estimated traffic worked out?

From the keyword's monthly searches and the click rate of that position. It is an estimate and covers Google search only.

How fresh are the rankings?

They come from a database, not a live check. Each row's rankedAt says when that keyword was last checked, which can be weeks or months ago.

Which countries?

92, including the US, UK, Canada, Australia, South Africa, India, Germany, France, Spain, Brazil and Japan.

What if a domain ranks for nothing?

You get a note and pay nothing for it.
