All 2 reader-funded Spanish science sites

Measured, not voted · 3 November 2026 · how it is measured

Ranked by what their readers pay: the paying supporters and the published yearly revenue on funding pages verified both ways, the site linking to the page and the page naming the site back. Every figure is one the named platform publishes; where it publishes nothing the row says so, and no estimate is shown as a number. Nothing here is paid for and nothing can be bought: a place on this list is evidence, and every row's evidence is one click away. Safe search is off: adult sites are ranked with the rest (turn on).
