How to use this
Copy any feed URL into whatever reader you use. NetNewsWire, Reeder, Feedbin, Inoreader and Miniflux all take a pasted URL. If you would rather not paste forty of them, take the category OPML and import it in one go. This page shows the 5 highest-ranked feeds per category to stay readable; the OPML packs carry all 498, and each category page lists its full set. Nothing here needs an account, and none of these links are affiliate links.
The badge on each row is the number of advertising domains that feed's own site contacted on the single page load we measured. Zero means zero on that load, in September 2026, from one country. It is a useful signal and it is not a promise about what you will see today.

How these were chosen, and what the numbers do not say
Every source was loaded in a real browser with its cookie banner accepted, so the page ran the way a reader actually sees it. We then counted advertising and third-party domains, layout shift, and the typography of an actual article. Eight scores per source, weights published, per-source measurements published.
Three things to hold against it. This is a curated list plus candidates we scored, not a census of the web, and it leans toward clean, fast, English-language sites. Each measurement is one page load from one country on one date, so treat a per-source number as a sample. And a homepage is not every article page. Full method, weights and the complete data: feeds.bar/signal-500/method. The whole catalogue as one file: signal-500.opml.
This directory exists because FeedsBar is built on it: a Mac ticker that carries the clean end of this list across the edge of your screen. You do not need it to use any of the feeds above, and the OPML is yours either way.
