Competitor Keyword Research – SEO Competitor Analysis Tool

See every Google keyword a website ranks for: its position, the ranking URL, monthly search volume, CPC, keyword difficulty, search intent and the traffic each keyword brings. Built for SEO teams, agencies, content marketers and AI agents doing competitor research, without a Semrush or Ahrefs subscription. The data comes from a licensed SEO data provider (DataForSEO's Google ranking database), so there is no scraping and no blocked runs.

What you get

• One summary row per domain: total ranked keywords (or, with a position filter, the keywords in those positions; see summary_scope), estimated monthly organic traffic and its Google Ads value, keywords in position 1 / top 3 / top 10, and how many are new, up or down. Free.
• One row per ranked keyword, the ones bringing the most traffic first: position, URL and title of the ranking page, search volume, CPC, competition, keyword difficulty (0–100), intent, estimated traffic, previous position and SERP features.
• Filters: number of keywords per domain (up to 10,000), only first-page (or top N) rankings, any country and language.

A Semrush, Ahrefs and SpyFu alternative for competitor keywords

The "organic keywords" report of Semrush, Ahrefs or SpyFu, as a pay-per-use Actor:

• What you get: every Google keyword a domain ranks for, with position, ranking URL, search volume, CPC, keyword difficulty, intent and estimated traffic, plus a visibility summary, for any country, in JSON, CSV or Excel.
• What it is not: there are no dashboards, site audits or historical charts; it is the keyword data itself, ready for a spreadsheet, a BI tool or an AI agent.
• No subscription, no login: pay per domain and per keyword row, so a one-off competitor check costs cents instead of a monthly plan.

Keyword gap: what your competitors rank for and you do not

List your competitors under domains and fill in yourDomain. You get only the keywords those competitors rank for on Google and your site does not, biggest traffic first, each with volume, CPC, difficulty, intent and the competitor's ranking page. Searches with the competitor's own name as a whole word are left out, because nobody wins those; gap_summary shows the word used (brand_word_left_out), and everyday-word site names such as cars.com are not filtered. Same price as a normal lookup. Rows have row_type: keyword_gap, and a free gap_summary row gives the total per competitor.

Input

Field	What it does
domains	Websites to analyse: semrush.com, https://www.example.com/blog (scheme, www and path are stripped). Up to 50 per run.
yourDomain	Optional. Your own website: you then get the keyword gap instead (below).
maxKeywordsPerDomain	How many keywords per domain, most traffic first. Default 20, up to 10,000.
maxPosition	Only keywords ranking at this position or better, e.g. 10 = first page. 100 = all.
location	United States, United Kingdom, Germany ... Empty = all locations.
language	English, German ... Empty = all languages.

Pricing

Pay per event, no subscription:

• $2 per 1,000 ranked keywords ($0.002 each).
• $0.02 per domain lookup of up to 1,000 keywords. Failed lookups are free. The summary row is free.
• $0.001 per run start.

Examples: the top 100 keywords of one domain cost about $0.22. 1,000 keywords cost about $2.02.

Try it for $0.001: the pre-filled example (python.org, 20 keywords, United States, English) is answered from a saved snapshot of a real lookup (rows carry from_snapshot: true) and costs only the $0.001 run start. Change anything and the lookup runs live.

Free Apify plan: the pre-filled example works on any plan. Live lookups need a paid Apify plan (any plan), because each one costs real money at the data provider; on the free plan the run returns a paid_plan_required row and charges nothing beyond the start.

You can cap the cost of a run with the maximum charge setting. The Actor only requests as many keywords as your budget can pay for, charges a lookup only when it succeeds, and stops after the first failed lookup.

Good to know

• A domain with no data, for example a typo, still costs one lookup: the lookup was made and paid for.

• Rankings and traffic estimates come from a ranking database refreshed regularly, not from a live Google search at run time. checked_at is the run time.

• estimated_traffic is a model estimate (search volume × click-through rate at that position), useful for comparing keywords and competitors, not an exact visit count.

• Error rows carry error and errorMessage and are never charged.
