Every tag this generator produces carries a number from 3 to 99. This page explains exactly how that number is produced, because a score you cannot interrogate is worth very little.
What goes into the score
Three inputs, combined deterministically:
Category weight. Each of the thirteen intent categories carries a base weight reflecting how crowded that kind of tag typically is. A tag from the low-competition bank starts near the bottom of the range; a tag from the viral bank starts near the top. This is the dominant factor.
Length. Longer tags are, reliably, less crowded. A twenty-character tag has a smaller pool of competing posts than an eight-character one almost without exception, because specificity and length correlate. Length pulls the score down.
Word count. A tag built from three word-parts is more specific again than one built from two, so each additional part pulls the score down further.
A small deterministic variation derived from the tag string itself prevents every tag in a group from landing on an identical number, which would make the ranking useless.
What the score is not
It is not a measurement of any platform. No public API provides accurate current post counts across Instagram, TikTok, YouTube, X, LinkedIn, Pinterest, Facebook and Threads, so nobody — including tools that display precise figures — has that data in a reliable, current form.
What tools in this category usually do is show numbers scraped at some past point, or numbers generated to look authoritative. Both are worse than an honest heuristic, because a precise-looking wrong number invites decisions a range would not.
How to use it
Treat the score as a sort order, not a measurement. Its job is to answer "which of these tags is more winnable than the others," and it does that well. It cannot answer "how many posts are on this tag right now," and it does not pretend to.
In practice: build most of a set from tags scoring under 55, add two or three in the 55–80 band for reach, and include at most one above 80.
Verify before you commit
For any tag you plan to build a campaign around, spend thirty seconds searching it on the platform itself. You will see the real post volume, whether recent posts exist, whether the content on it is anything like yours, and whether the tag carries a restriction warning. That check is more valuable than any tool's number, this one included.
