Competitor Keywords Finder

Competitor Keywords Finder shows what keywords a website ranks for on Google — for any competitor domain or single page URL, in 94 countries. Every row is one ranked keyword of one domain with its Google position, the ranking URL, search volume, CPC, Google Ads competition, keyword difficulty, search intent, estimated traffic (ETV), the position change since the previous check and the SERP features on that results page.

It is a SEMrush alternative for competitor keyword research without a subscription: put in one or many competitors, set the country, language and filters, and get one flat table. Optional add-ons find the organic competitors of a domain, pull their keywords in the same run, and add a summary row per domain. $0.0015 per keyword on paid plans ($0.002 on the Apify Free plan). Keywords without search volume data are free. No fee per run, no login, no API key of your own.

What is Competitor Keywords Finder?

It is an organic keywords API and competitor keyword research tool in one Actor. You enter ahrefs.com, and it answers "which Google keywords bring this site its traffic?" — sorted by estimated traffic, search volume, position, CPC or keyword difficulty. Enter a page URL such as https://ahrefs.com/keyword-generator, and you get the keywords of that one page.

Search volume, CPC and competition are aggregated from Google Ads Keyword Planner and clickstream data via a licensed data provider; positions come from that provider's regular checks of Google results pages. Each row says when the results page was last checked (serpCheckedAt). You do not need an account with any SEO tool — the Actor handles the data access and bills you per keyword row.

What it is not: it does not crawl Google live for every keyword, it does not show rankings from the last hour, and keyword difficulty and estimated traffic are model estimates, the same kind every SEO tool shows, not numbers Google publishes.

What data can Competitor Keywords Finder extract?

One row per domain and ranked keyword (type = "keyword"):

Field	Example	Meaning
domain	ahrefs.com	Competitor domain or page URL you entered
keyword	ai rewriter	Keyword the domain ranks for
position	1	Google position among results of the same type (1 = first organic result)
absolutePosition	1	Position counting every element on the page (ads, snippets, boxes)
resultType	organic	organic, paid, featured_snippet, local_pack or ai_overview_reference
rankingUrl	https://ahrefs.com/writing-tools/paragraph-rewriter	Competitor page that ranks
rankingTitle	Free AI Paragraph Rewriter	Title shown on Google
searchVolume	49500	Average monthly Google searches in the chosen country
cpc	2.6	Average cost per click in Google Ads, USD
competition, competitionLevel	0.28, LOW	Google Ads competition
keywordDifficulty	28	0 (easy) to 100 (hard)
searchIntent	commercial	informational, navigational, commercial or transactional
estimatedTraffic	15950.57	Estimated monthly visits from this keyword (ETV)
estimatedTrafficCost	41471.49	What that traffic would cost in Google Ads per month, USD
previousPosition, positionChange	1, 0	Absolute position at the previous check and the change (positive = moved up)
isNew, isUp, isDown, isLost	false	Ranking movement flags
serpFeatures	["organic", "product_considerations", "related_searches"]	What else is on that Google page
searchVolumeTrendYearly	-33	Search volume change over the last year, %
targetType	domain	domain or page
competitorOf	backlinko.com	Filled when the row belongs to a competitor the Actor found
location, language	United States, en	Country and language used
serpCheckedAt	2026-07-30 05:03:58 +00:00	When the results page was last checked
charged	true	false = no search volume data, row is free

Position, URL, volume, CPC, difficulty, intent and traffic sit in one row, so you can sort and filter the table without joining exports from three tools.

Competitor rows (add-on)

With Find competitors of each domain on, you also get one row per organic competitor (type = "competitor"): domain, competitorOf, competitorRank, sharedKeywords, avgPosition on the shared keywords, sharedKeywordsTraffic, the competitor's totalKeywords, estimatedTraffic, estimatedTrafficCost, top3Keywords, top10Keywords. Competitors are sorted by shared keywords; Google, YouTube, Wikipedia and other giant sites are left out.

Domain summary rows (add-on)

With Add a summary row per domain on, each domain gets one row (type = "domainSummary"): organicKeywords, matchingKeywords, estimatedTraffic, estimatedTrafficCost, top1Keywords, top3Keywords, top10Keywords, pos11to20Keywords, pos21to100Keywords, newKeywords, upKeywords, downKeywords, lostKeywords. The counts follow your filters and selected result types. It is off by default, so the default table has one row type only.

How much does it cost to find competitor keywords?

Event	Free plan	Starter (Bronze)	Scale (Silver)	Business (Gold)
💰 Keyword (one ranked keyword row with search volume)	$0.002	$0.0015	$0.0015	$0.0015
Competitor (add-on, one competitor found)	$0.002	$0.0015	$0.0015	$0.0015
Domain summary (add-on, one row per domain)	$0.003	$0.0027	$0.0024	$0.0021
Run start	$0 — no start fee	$0	$0	$0
Keywords without search volume data, error rows	$0	$0	$0	$0

On paid plans that is $1.50 per 1,000 ranked keywords, about 666 keywords per $1. On the Apify Free plan it is $2 per 1,000, so the $5 of monthly free credit covers about 2,500 keywords. Platinum and Diamond plans pay the Business price.

Filters run before the limit, at the data source: keywords you filter out are never fetched and never billed. Max keywords per domain and Max keyword rows per run are hard ceilings on what you pay. The default run — 20 keywords of ahrefs.com — costs $0.03 on paid plans ($0.04 on the Free plan) and finished in about 4 seconds in our test.

A built-in spend guard stops a run early when the domains return very few keywords for the requests they need (for example a long list of tiny sites that rank for almost nothing). The log and the run status say so; nothing extra is billed.

How to find competitor keywords with Competitor Keywords Finder

1. Open the Actor and enter one or more competitor domains or URLs, one per line.

A competitor row (add-on):

{
  "type": "competitor",
  "domain": "semrush.com",
  "competitorOf": "backlinko.com",
  "competitorRank": 1,
  "sharedKeywords": 22106,

  "top3Keywords": 15597,
  "top10Keywords": 44233,
  "location": "United States",
  "language": "en"
}

The Console shows four tabs: Ranked keywords (the main table), Competitors, Domain summary and All fields. With the add-ons off, every row is a keyword row.

Error rows

If an input cannot be used — something that is not a domain, an unknown country, a page URL in competitor discovery, or a domain with no ranked keywords for your country and filters — the Actor adds a free row:

{ "type": "error", "input": "not a domain", "error": "Not a domain or URL (expected something like example.com or https://example.com/page). Not charged.", "scrapedAt": "2026-10-01T13:39:33.000Z" }

A small or new site can have very few keywords in the data source; then you get fewer rows or one free error row that says so. A run summary (requests, cache hits, rows, free rows) is saved in the key-value store as SUMMARY.

Use cases for competitor keyword data

SEO content planning

Find the keywords that bring your competitors the most traffic, filter to maxKeywordDifficulty 30 and write the pages they rank with and you do not.

Keyword gap analysis

Put your domain and three competitors in one run. Sort by keyword: rows where competitors rank and your domain does not are your gap.

Paid search research

Add paid to result types to see which keywords a competitor buys Google Ads on, with CPC and competition in the same row.

Agency audits and pitches

One run per prospect: summary row plus top 100 keywords by traffic, exported to Google Sheets.

Rank monitoring of competitors

Schedule the run weekly; isNew, isUp, isDown and positionChange show what moved.

AI search visibility

Select ai_overview_reference to see for which keywords a domain is cited inside Google AI Overviews.

AI agents and LLM pipelines

An agent can call the Actor with one domain and get structured keyword rows back in seconds — for content briefs, competitor reports and SEO assistants.

Integrations

Every run is available through the Apify API, and the Actor works with n8n, Make, Zapier, Google Sheets, Airbyte, LangChain and the Apify MCP server.

Python:

from apify_client import ApifyClient

client = ApifyClient("<YOUR_API_TOKEN>")
run = client.actor("lergassy/competitor-keywords-finder").call(run_input={
    "domains": ["backlinko.com", "semrush.com"],
    "location": "US",
    "maxKeywordsPerDomain": 200,
    "excludeBrandKeywords": True,
})
for row in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(row["domain"], row["keyword"], row["position"], row["searchVolume"])

JavaScript:

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: '<YOUR_API_TOKEN>' });
const run = await client.actor('lergassy/competitor-keywords-finder').call({
    domains: ['ahrefs.com'],
    maxKeywordsPerDomain: 100,
    sortBy: 'searchVolume',
});
const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items.length);

🤖 For AI Agents & LLM Apps

Compact reference for agents calling this Actor through the Apify MCP server or the Apify API (lergassy/competitor-keywords-finder).

Purpose: one row = one Google keyword a domain or page URL ranks for, with position, ranking URL, search volume, CPC, competition, keyword difficulty, search intent and estimated traffic. Answers "what keywords does example.com rank for?", "which pages bring a competitor traffic?", "who are a domain's organic competitors?".

Minimal input:

{ "domains": ["example.com"] }

Output: type, domain, keyword, position, absolutePosition, resultType, rankingUrl, rankingTitle, searchVolume, cpc, competition, competitionLevel, keywordDifficulty, searchIntent, estimatedTraffic, estimatedTrafficCost, previousPosition, positionChange, isNew, isUp, isDown, isLost, serpFeatures, searchVolumeTrendYearly, targetType, competitorOf, location, language, serpCheckedAt, charged, scrapedAt. Competitor rows (type = "competitor") and summary rows (type = "domainSummary") appear only when their add-ons are on.

Behaviors an agent should know:

• maxKeywordsPerDomain (default 20) caps rows and cost per domain; maxResults (default 10,000) caps the run.
• Use minSearchVolume, maxPosition, maxKeywordDifficulty, searchIntents, excludeBrandKeywords, excludeWords, includeWords instead of post-filtering; they apply before the limit and filtered keywords are not billed.
• A URL with a path is analysed as one page; competitor discovery works on whole domains only.
• Positions are from the data provider's latest check of each results page (serpCheckedAt), not a live search; difficulty and traffic are estimates.
• Billed on paid plans: $0.0015 per keyword row with search volume; $0.0015 per competitor; $0.0027 (Starter) to $0.0021 (Business) per summary row. On the Free plan: $0.002, $0.002 and $0.003. Rows with charged = false, error rows and run start are free.
• serpFeatures is the only array field; everything else is flat.

❓ FAQ

Is it legal to look up competitor keywords?

The Actor returns aggregated search statistics and public Google rankings — the same kind of data every SEO tool sells. It contains no personal data. Check your local law and the terms that apply to your use case; when in doubt, consult a lawyer.

Is this a SEMrush or Ahrefs alternative?

For the "organic keywords of a competitor" report, yes: domain or URL in, ranked keywords with position, volume, CPC, difficulty, intent and traffic out — billed per keyword, without a monthly subscription. It does not have backlink, site audit or rank tracking projects.

Where does the data come from?

Search volume, CPC and competition are aggregated from Google Ads Keyword Planner and clickstream data via a licensed data provider; rankings come from that provider's regular checks of Google results pages. The same request within 7 days is answered from a cache, so repeated runs return the same numbers.

How fresh are the positions?

Each row has serpCheckedAt: the date the provider last checked that results page. Popular keywords are checked more often than rare ones; expect days to weeks, not minutes.

Why did I get fewer keywords than I asked for?

The domain ranks for fewer keywords that match your country, language, result types and filters. Small or new sites can have only a handful of keywords in the data source. A domain with none gives one free error row.

Which countries and languages are supported?

94 Google countries — United States, United Kingdom, Germany, France, India, Indonesia, Australia, Brazil, Japan and more — each with its available languages. An unknown country gives a free error row with the full list of codes.

How much does a typical run cost?

On paid plans the default run (20 keywords) costs $0.03, 1,000 keywords cost $1.50, 10,000 keywords $15, and finding 10 competitors adds $0.015. On the Free plan the same cost $0.04, $2, $20 and $0.02. There is no start fee.

Can I use Competitor Keywords Finder with the Apify API?

Yes. Start runs, read datasets and schedule jobs with the Apify API, or the Python and JavaScript clients shown above.

Can I use it through an MCP server?

Yes. Add the Apify MCP server (https://mcp.apify.com) to Claude, Cursor or any MCP client and call lergassy/competitor-keywords-finder as a tool.

Can I integrate it with other apps?

Yes — n8n, Make, Zapier, Google Sheets, Airbyte, Slack and webhooks through Apify integrations.

Is each keyword one row?

Yes: one row per domain and keyword. When a page ranks for the same keyword in two result types (for example organic and AI Overview), each is its own row with its own resultType and position.
