How it's measured →0.2%
of downloads still active
At least 10 of 6.4K lifetime downloads are still running, below its category: the median Uncategorized plugin keeps 0.6%, across 17,573 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Uncategorized plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
Directory ranking optimization

Excellent listing optimization
Most to gain: Rating quality
To rank higher: No reviews yet. wp.org scores an unrated plugin as middling on rating, so the first good reviews lift it.

How it's tracked →Directory searches this plugin turns up in, and which way each one is moving. WordPress.org publishes no history of search positions, so this starts the day we first tracked a keyword and never backfills.
Not enough tracked days yet to call a direction. Momentum needs at least three keywords measured a week or more apart.
| Keyword | wp.org | On merit | Change |

| twentytwenty | #11 | #18 | — |
| ubl | #12 | #10 | 0 |
| fullwidth | #15 | #19 | 0 |
What to do about it
- Add “twentytwentyone” and “ubl” to your wp.org tags. You already rank #3 and #12 for them without listing them. WordPress.org counts only your first five tags, so these are the slots worth spending.

Estimated value
What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.
Est. annual revenue
Est. acquisition value
No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from. The recent download trend is too spiky to read.
