Biggest opportunity: Swap “reader” and “viewer” for “comic sans” and “ebooks”. “reader” isn't earning its slot: it only gets you to #24. “comic sans” sits at #4 untagged, close enough for a declared tag to move it up. “viewer” isn't earning its slot: it only gets you to #19. “ebooks” sits at #4 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

How it's measured →8.4%
of downloads still active
At least 400 of 4.7K lifetime downloads are still running, above its category: the median Uncategorized plugin keeps 0.6%, across 17,766 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.
This plugin shipped 7 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

What to do about it
- Swap “reader” and “viewer” for “comic sans” and “ebooks”. “reader” isn't earning its slot: it only gets you to #24. “comic sans” sits at #4 untagged, close enough for a declared tag to move it up. “viewer” isn't earning its slot: it only gets you to #19. “ebooks” sits at #4 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

Estimated active installs
The public count shows “400+”. Our estimate pins where the real number sits.
Crossed into this band 2 months ago and a band this size takes about a year or more to cross, so the real count is still just over 400.
At the current install trend, crossing 500+ in roughly 129 days.

The plugin is the best for epub viewing and it has more customization options than any of the PDF viewers out there. The developer is also active and continues to support the plugin when issues arise. Very good plugin!

The best solution for comfortably viewing and reading ebooks on a website. Even better than some ebook reading apps.

The only solution on the market, and works effortlessly. Would be great if we could load ebooks from external links e.g. from GoogleDrive URL. This topic was modified 10 months, 2 weeks ago by joykingwar.
