Google Trends
Tool · this deep dive is built from the official pages of the platform itself and of the tools that support it.
Overview
Google Trends is an instrument that shows how the frequency of queries has changed over time. It lives at trends.google.com/trends/.
The only statement about the substance of its work is taken from a help centre page and sounds narrow: it is about "searches people make on Google", that is, about search queries in Google (help centre).
The interface language of the homepage is en-US, taken from the markup attribute. Two readings of the markup diverge: one gives the language as en, the other as en-US. The difference is in the regional qualifier, not in the language, but the records differ. Both agree on the main point: the site declares no hreflang and contains no language switcher visible in the markup.
Which platforms it works with
There is no list of source platforms on the official help centre page. It speaks only of search queries in Google (help centre).
The caveat here is an important one. A breakdown of sources — including YouTube Search — is visible in the interface of the Explore section, but that interface is assembled by scripts, and there is no statement about sources in the text of the page. That is, we cannot confirm the set of sources from a readable source: seeing something in the interface and having a written assertion from the tool are different grounds, and we rely on the second.
The help centre page names no social networks as sources at all. There is no connecting of accounts here in any form: the instrument looks at depersonalized query statistics, not into your profiles.
How you earn with it
An affiliate programme is not announced: the addresses /trends/affiliate, /trends/partners, /trends/referral return 404, and the tool has no separate affiliate programme page (Google Trends).
Calling Google Trends a free instrument of Google's is our annotation, not a statement by the source.
What it will not do
It does not attempt to tell anything about itself in the sources we checked: there is no description of the tool among the facts.
Nor does it let you state in writing where it takes its data from beyond Google search. The interface shows a breakdown by source, but it cannot be read without executing scripts, and the help centre page is silent about it.
It does not claim to work with social networks: not a single platform is named on the page we checked, and there is no talk of connecting accounts of any kind.
Nor does it let you declare its language versions: there is neither hreflang nor a switcher in the markup — and this for an instrument that is international by definition.
The limits of use — how many queries, what depth of history, whether data can be exported — the open pages do not name.
It does not offer to pay for a referred user: it has no programme of its own.
