Keyword Search Volume API: Google Ads Volume, CPC & Trends

Keyword Search Volume API returns Google search volume for your keywords straight from Google Ads (Keyword Planner) data: average monthly searches, a 12-month search history, CPC, low and high top-of-page bids, competition and a ready-made trend (3-month and year-over-year change). Check up to 1,000 keywords per lookup and up to 100,000 per run, for any country, region or city and any language.

You don't need a Google Ads account, an active ad campaign or an API key. Paste keywords, click Start and export to JSON, CSV or Excel, or call it from the API, Make, Zapier, n8n or an AI agent.

How much does keyword search volume cost?

This Actor uses pay-per-event pricing:

Event	Price
Keyword with data	$1.50 per 1,000 keywords ($0.0015 per keyword)
Lookup (one batch of up to 1,000 keywords)	$0.10 per lookup
Actor start	$0.00005 per run

Keywords without data, invalid keywords and duplicates are free. Examples:

• The prefilled example (4 keywords): about $0.11
• 1,000 keywords: about $1.60
• 10,000 keywords: about $16
• 100,000 keywords: about $160

Set Maximum cost per run in the run options to cap spending; the Actor stops before it would go over.

This Actor is available on paid Apify plans (Starter and higher), because every lookup costs us Google Ads data fees. On the Free plan the run ends right away with a short notice and you are not charged.

Use it with AI agents (MCP) and the API

Add this Actor as a tool in Claude, ChatGPT, Cursor, VS Code or any other MCP client through the Apify MCP server:

https://mcp.apify.com?tools=magenta_waterwheel/keyword-search-volume

Then ask, for example: "Get US search volume and CPC for these 200 keywords and list the 20 with the best volume-to-competition ratio." The Actor runs with limited permissions, so it can only access its own run storage.

For results in a single HTTP request, call the synchronous endpoint with your Apify API token:

curl -X POST "https://api.apify.com/v2/acts/magenta_waterwheel~keyword-search-volume/run-sync-get-dataset-items" \
  -H "Authorization: Bearer $APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"keywords":["buy laptop","best gaming laptop"],"location":"United States","language":"en"}'

FAQ

Where does the data come from?

From Google Ads keyword planning data, delivered through a licensed data provider (DataForSEO). It is the same source as Google Keyword Planner, without needing your own Google Ads account or ad spend.

Why do some keywords have no data?

Google doesn't report volume for very rare keywords, some brand or adult terms, and keywords it groups with a close variant. Those keywords come back with hasData: false and cost nothing.

Why do similar keywords show the same volume?

Google Ads combines search volume for close variants (plurals, misspellings, word order). If you need them separated, check them in separate runs.

How fast is it?

About 5-10 seconds per lookup of up to 1,000 keywords. The data provider allows a limited number of lookups per minute, so very large runs (tens of thousands of keywords) take a few minutes.

Can I use it on the Free plan?

No. Each lookup has a real data cost that Apify doesn't cover on the Free plan, so the Actor needs a paid Apify plan. Free-plan runs end immediately with a notice and no charge.
