Compare keywords on Google Trends

TL;DR

Automatically compare keywords on Google Trends on trends.google.com. See which of up to five terms gets more search interest, over time and by region.

About

Google Trends scales each result to the peak of that one request, so terms only compare fairly when fetched together. A US camping gear shop planning spring ads could send ["tent", "hammock", "sleeping bag"] with geo "US" and date "today 5-y", then read interestOverTime to see when each tops out, year after year. With two or more terms, regionShare splits interest by state, showing where hammocks beat tents. Related topics need a single term, so a second call with "hammock" alone adds them, and a rising query marked Breakout (over 5000% growth) can earn its own ad group. These are indexes, not search counts: a low-volume term reads 0 beside bigger ones, and if every term is that small the timeline comes back empty. Labels and region names come back in English whatever geo you pick. As of early October 2026, every run on Reduck's hosted browsers had failed, so use the Reduck extension in your own Chrome.

Input

keywords required

1-5 search terms and/or Trends topic mids (e.g. "/g/11khcfz0y2") compared in a single query — values are relative to the shared peak, so this is the only way to compare terms. Terms must not contain commas (the site's own separator).

geo optional

ISO region code: "US", "FR", "US-CA"… Empty string = worldwide.

Default: ""
date optional

Trends range: "now 1-H", "now 4-H", "now 1-d", "now 7-d", "today 1-m", "today 3-m", "today 12-m", "today 5-y", "all", or explicit "YYYY-MM-DD YYYY-MM-DD".

Default: "today 12-m"
category optional

Trends category id (0 = all categories). Same ids as the site's category picker.

Default: 0
property optional

Search property: "" = web search, images, news, froogle (shopping), youtube.

Default: ""

Output

geo required
date required
keywords required
byKeyword required

Per-keyword panels, aligned with keywords. relatedTopics is null in compare mode — the site drops that panel when comparing.

regionShare required

Compare mode only (2+ keywords), else []: each keyword's share (%) of combined interest per region, shares[i] aligns with keywords[i].

interestOverTime required

Relative interest 0-100, shared scale across all keywords (100 = the overall peak). values[i] aligns with keywords[i]. Empty for insufficient volume.

FAQ

Google Trends explore for 1-5 keywords in one compare query: interest over time (shared scale), interest by region, per-region share %, related topics and queries (top and rising), for a given geo, date range, category and property.
Ask an AI agent connected to Reduck to run reduck/trends.google.com/explore_keyword, or run it from a terminal with the Reduck CLI: npx @reduck-ai/cli@latest run --script reduck/trends.google.com/explore_keyword
You do not need one. "Compare keywords on Google Trends" drives the real trends.google.com pages in a browser, so it works whether or not trends.google.com offers an API for this.
Required: keywords. Optional: geo, date, category, property.
It returns geo, date, keywords, byKeyword, regionShare, interestOverTime.
No. It only uses pages of trends.google.com that are reachable without signing in.
It only reads. It looks things up on trends.google.com and changes nothing there.
Ask an AI agent connected to Reduck to run reduck/trends.google.com/explore_keyword, or run it from a terminal with the Reduck CLI: npx @reduck-ai/cli@latest run --script reduck/trends.google.com/explore_keyword
It is part of Reduck's official curated catalogue.
The keywords field takes at most five terms, the same limit as Google's classic Explore page, which explore_keyword opens. The redesigned Explore page in the browser goes up to 8 groups of terms. For a longer list, keep one anchor term in every batch of five and rescale the others against it, since each call sets its own 100.
When Google answers the explore request with an error such as HTTP 429, the run stops with an error that says so instead of returning partial data, so wait a while and retry. The run also fails if the charts have not all loaded within 20 seconds.
Google's Trends API, announced in July 2025, is still an alpha in October 2026: access goes through an application form for testers, and its page lists no price. That API serves a rolling five years at daily or coarser intervals and lets you merge requests to compare dozens of terms. explore_keyword reads the public explore page instead, so it needs no application and also takes date "all" or hour ranges such as "now 4-H".
Take a term from trending_now, which lists what is spiking in one country over the last 4 hours to 7 days, and run explore_keyword on it with date "today 5-y", because the default 12-month window cannot show a peak that returns each year. A one-off spike shows a single peak, while a seasonal term rises around the same weeks every year. The breakdown terms trending_now returns for each trend can go straight into keywords, up to five per call.
