SEO Competitor Keywords - Domain Ranked Keywords & Keyword Gap

What does SEO Competitor Keywords do?

SEO Competitor Keywords finds the Google keywords any domain or competitor ranks for, with the position, the ranking URL, search volume, CPC, keyword difficulty, search intent and estimated traffic on every row. It also lists the organic competitors of a domain and runs a keyword gap between your site and up to 4 competitors, so you see the keywords they win and you don't.

It works like the "Organic Research", "Organic Competitors" and "Keyword Gap" reports of Semrush or Ahrefs, as an API: no Semrush or Ahrefs subscription needed. Data comes from the DataForSEO Labs Google database (billions of keywords, 94 countries). Run it from the Apify Console, the API, Zapier, Make, n8n or an AI agent through MCP.

Why use it?

• Competitor keyword research: see every keyword a competitor gets traffic from, which page ranks, and how much traffic it brings.
• Keyword gap / content gap: find the keywords 1-4 competitors rank for and your site doesn't rank for at all. Keywords that several competitors share come first.
• Find your real competitors: list the domains that rank for the same keywords as you, with common keywords, average position and their total traffic.
• SEO reporting and rank tracking: export the positions of your own domain with the previous position, new/up/down flags and the featured snippet flag.
• Agencies and AI agents: bulk-analyze up to 50 domains per run and feed the JSON into reports, spreadsheets or LLM workflows.

How to find the keywords a competitor ranks for

1. Open the Actor and pick a Mode: Ranked keywords, Organic competitors or Keyword gap.
2. Enter one or more domains (example.com or any URL). For a keyword gap, put your domain first, then 1-4 competitors.
3. Choose the country and language (94 countries; names or codes like US, GB, de work).
4. Optional: set Max rows per domain (up to 10,000), Max Google position (10 = first page) and Min monthly search volume.
5. Click Start and download the results as JSON, CSV, Excel or HTML.

How much does it cost?

Pay per result, no subscription:

• $3 per 1,000 keywords ($0.003 per ranked-keyword or keyword-gap row)
• $3 per 1,000 competitor rows ($0.003 per competitor)
• $0.02 per domain with data (covers the data provider's fixed fee per lookup)

Example: the top 500 keywords of one competitor cost $1.52. Invalid domains, domains with no data, duplicates and errors are free. Set a max cost per run and the Actor stops there, only buying the data you can pay for.

Free Apify plan: 1 domain and 10 rows per run (keyword gap: your domain vs 1 competitor), because every lookup costs the developer a data fee. Any paid Apify plan gets up to 10,000 rows per domain and 50 domains per run.

Input

{
    "mode": "keywordGap",
    "domains": ["apify.com", "scrapingbee.com", "brightdata.com"],
    "location": "United States",
    "language": "English",
    "maxRowsPerDomain": 500,
    "maxPosition": 20,
    "minSearchVolume": 100,
    "gapType": "missing"
}

Output

One row per keyword (or competitor). Download it as JSON, CSV, Excel or HTML, or read it through the API.

{
    "type": "rankedKeyword",
    "domain": "apify.com",
    "keyword": "web scraping tools",
    "position": 3,
    "previousPosition": 5,
    "rankingUrl": "https://apify.com/...",
    "searchVolume": 9900,
    "etv": 1210.5,
    "cpc": 6.12,
    "keywordDifficulty": 48,
    "intent": "commercial",
    "serpFeatures": ["people_also_ask", "video"],
    "isFeaturedSnippet": false,
    "totalRankedKeywords": 6953,
    "location": "United States",
    "language": "English"
}

Keyword gap rows add yourPosition (null = you don't rank), positions ({"apify.com": null, "brightdata.com": 5}), rankingUrls, bestCompetitor and competitorsRanking. Rows with an error field are free notes (invalid domain, no data).

Tips

• Rows come highest traffic first, so a small Max rows per domain already gives the keywords that matter.
• Use Max Google position 10 to see only first-page keywords, and Min monthly search volume to skip the long tail.
• Missing gap = content ideas (competitors rank, you don't). Shared gap = keywords you can push up (both rank; compare positions).
• Enter the root domain (example.com) for the whole site, or a subdomain (blog.example.com) for just that part.
• Big runs (many domains with 10,000 rows each) can take a while. If the run's timeout comes close, the Actor stops cleanly: you keep and pay for the rows already found, and the domains not reached are listed as free rows.

FAQ

Do I need a Semrush, Ahrefs or DataForSEO account?

No. The data access is included in the price per result.

How fresh is the data?

Positions come from the DataForSEO Labs Google database, which is refreshed continuously; each row's SERP is usually from the last few weeks. It is an estimate like Semrush or Ahrefs data, not a live Google check.

Which countries are supported?

94 countries, with local languages (for example United States English/Spanish, Canada English/French, Switzerland German/French/Italian).

Why does a domain return no keywords?

Small or new sites may not rank in the top 100 for any keyword the database tracks in that country. Those rows are free; try another country. If 10 domains in a row have no data, the run stops and lists the rest as free rows, because that almost always means the wrong country or language.
