Does every website have an RSS feed?
No. Most CMS-powered sites (WordPress, Ghost, Substack, Tumblr) publish feeds automatically, but static sites, custom frameworks, and some marketing platforms do not. The finder probes common endpoints and platform-specific URL patterns; if none return a valid feed, the site probably does not expose one publicly.
What is the difference between RSS, Atom, and JSON Feed?
RSS 2.0 and Atom are XML-based feed formats; JSON Feed uses JSON. All three describe the same thing: a list of items with titles, links, dates, and optional content. Aggregator imports all three. The finder detects the format automatically from the content type and document shape.
How do I know if a feed is worth importing?
Look at Full Text availability, images, author fields, dates, duplicate risk, and freshness. The checker surfaces those signals from a live sample of items, so you can see what will and will not carry through before you import. Feeds with Full Text, dates, and images import cleanly; missing fields can usually be patched inside Aggregator with Full Text or fallback images.
Why does Reddit or Pinterest sometimes show a generated URL without a preview?
Some platforms block automated requests from cloud hosting providers even when the RSS URL itself is valid. In those cases the finder returns the correct URL pattern but cannot fetch a live sample. Copy the URL and test it from inside Aggregator on the WordPress site, which typically resolves the block.
Is the RSS feed finder free?
Yes. This tool is free to use and does not require an account. It is part of the Aggregator ecosystem; once a feed is found, the Get Started button hands off to Aggregator for actual importing.
Can I find feeds for platforms without native RSS?
Platforms like LinkedIn, Facebook, Instagram, TikTok, and X/Twitter have removed or never had public RSS. The platform directory documents what is and is not available for each one, including known third-party workarounds where they exist.
