Most keyword research comes down to one loop: start from a few seed terms, expand them into everything people actually search, then keep the ones with real volume and a difficulty you can win. Here's how to run that loop from code, paying per keyword instead of per month, plus what a real run returns and where the data falls short.

Three ways to expand seeds

Disclosure: we (SteadyScrape) built the tool below and get paid when it's used.

Keyword Research Tool: Ideas, Volume, KD & Intent (steady-scrape/keyword-research-explorer) is an Apify Actor with three modes:

Every keyword comes back with monthly search volume (plus the last 12 months), CPC and top-of-page bid range, keyword difficulty (0–100), search intent, SERP features and trend percentages (vs last month, 3 months and 1 year ago).

What a real run returns

We ran the Actor's prefilled example input: one seed, coffee grinder, in ideas mode, 25 keywords, minimum volume 10, United States / English.

• 25 keywords returned (out of 615,725 ideas available for that seed), in about 3 seconds.
• Cost at the Free-plan list price: $0.02 run + $0.02 database request + 25 × $0.003 + $0.00005 Apify start fee = $0.115.

A few of the rows:

Be aware that ideas mode is broad: the same 25 rows also included coffee shops, 7 brew coffee and a few roaster brand names. That's useful for mapping a whole topic, but for a tight list use suggestions mode (every keyword contains the seed) or add includeWords / excludeWords.

Example: low-competition topics for a content calendar

from apify_client import ApifyClient

client = ApifyClient("<YOUR_APIFY_TOKEN>")
run = client.actor("steady-scrape/keyword-research-explorer").call(run_input={
    "seedKeywords": ["coffee grinder", "espresso machine"],
    "mode": "ideas",
    "limitPerSeed": 200,
    "location": "United States",
    "language": "English",
    "minSearchVolume": 50,
    "maxKeywordDifficulty": 40,
    "excludeWords": ["repair"],
})
for row in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(row["keyword"], row["searchVolume"], row["keywordDifficulty"], row["searchIntent"], row["trendYearlyPct"])

Filters (volume, difficulty, intent, include/exclude words, questions only) run before you're charged, and duplicates across seeds are removed for free.

Turning the list into content

• Questions only (questionsOnly: true) gives you FAQ and blog-post titles straight away.
• Group by searchIntent: commercial terms for comparison pages, informational for guides.
• serpFeatures tells you when a featured snippet, People Also Ask box or AI Overview is on the page.
• The trend fields flag seasonal or rising topics before you commit.

Limits worth knowing

• Volumes come from a licensed keyword database refreshed monthly, so they're monthly averages, not live counts. Expect the same order of magnitude as Google Keyword Planner, not identical numbers.
• Google only. Not for YouTube, Amazon or Bing volumes.
• The Apify Free plan is capped at 3 seeds and 100 keywords per run (enough to try it on your own topic).

Cost

$0.003 per keyword (less on paid Apify plans: $0.0027 / $0.0024 / $0.00225), plus $0.02 per run with results and $0.02 per keyword-database request, and Apify's $0.00005 start fee. ideas mode makes one request for all seeds; suggestions and related make one per seed; every extra 1,000 keywords is one more request.

• The test run above: $0.115 for 25 keywords.
• 100 ideas for one seed: $0.02 + $0.02 + 100 × $0.003 = $0.34.
• 1,000 ideas from 5 seeds: $0.02 + $0.02 + 1,000 × $0.003 = $3.04.

Runs with no results, seeds that return nothing and filtered-out keywords aren't charged.

Try it on the Apify Store: the prefilled example input runs the same test shown above. If you already have a keyword list and only need volumes, there's also Keyword Search Volume, and to find the keywords your competitors rank for and you don't, Competitor Keyword Gap.
