How to Check Tumblr Notes and Reblogs for Any URL (Free Methods)

SignalBoost Team · October 2026 · 5 min read

Tumblr is the internet's reblog machine: one post picked up by the right blogs can ricochet across the dashboard for weeks, and every reblog is a backlink-shaped signal pointing at your content. On Tumblr, engagement is counted in notes — likes plus reblogs combined. Here is how to check the note count for any URL, free.

1. One-click notes checker (easiest)

Paste any URL into a free social signals checker and you get the Tumblr note count alongside 14 other platforms — no signup, results in seconds. This is the method 99% of people should use.

2. Tumblr's own API (for developers)

Tumblr's public API exposes note counts per post. With a free API key, the blog posts endpoint accepts notes_info=true and returns the total note count for each post — likes and reblogs included. No key? Many checker tools are built on top of this exact endpoint.

3. Tumblr search

Type your keyword or domain into Tumblr's search. You will see the most-reblogged posts on your topic and get a feel for which formats travel furthest — great for planning content Tumblr actually amplifies.

4. Your own blog's activity page (your content)

If the content is yours, your Tumblr dashboard's activity view shows exactly which posts earned notes and who reblogged them. Free, and the most accurate source for your own posts.

What high note counts tell you

Posts with big note numbers usually share three traits: a strong visual or quotable hook, a niche community that reblogs heavily, and evergreen topic appeal. When you check shares across platforms and Tumblr dominates, double down — make follow-up content on that topic and seed it to the blogs that reblogged you first.

The bottom line

Note counts are the fastest way to spot content Tumblr's communities already love. Check any URL below — free, instant, no signup.
