Biggest opportunity: Swap “downloadable”, “downloads” and “e commerce” for “mobi”, “ebooks” and “watermarking”. “downloadable” isn't earning its slot: you're not in the first 24 results for its own search. “mobi” sits at #4 untagged, close enough for a declared tag to move it up. “downloads” isn't earning its slot: you're not in the first 24 results for its own search. “ebooks” sits at #8 untagged, close enough for a declared tag to move it up. “e commerce” isn't earning its slot: you're not in the first 24 results for its own search. “watermarking” sits at #8 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 →1.2%
of downloads still active
At least 100 of 8.1K lifetime downloads are still running, in line with its category: the median eCommerce plugin keeps 1.4%, across 5,141 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other eCommerce 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 5 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.

wp.org is where the directory puts the plugin for that search. On merit is where it would sit if results were ranked on rating, support and updates, without the install boost. The last column is how far the wp.org position moved, from our first reading in the last 90 days to the latest.

What to do about it

Lemon Ink is very well-designed, uncomplicated, and easy to use. I used a different plugin for securely selling ebooks and when it deteriorated I researched several others. Lemon Ink turned out to be the best choice for preventing piracy without inconveniencing purchasers. Note that unused credits expire one year after purchase, so a) don’t buy more than you expect to use up within one year, b) use Lemon Ink’s system for automatically purchasing any number of credits when you are about to run out of them.

Plugin works absolutely fine. We are very happy with it. And with the helpdesk. When we encountered a problem (it turned out we ourselves made a mistake), the helpdesk responded promptly and investigated the matter thoroughly. Problem solved in no time!

Lemonink made it so simple and elegant. We were really struggling with our older DRM system, with multiple complaints weekly and poor UX. Lemonink is super easy for the customer, super intuitive for publishers and comes with great support. The developers are active and listening to our comments and addressing them timely.

The plugin is super easy to configure on the WooCommerce backend. Whole process of watermarking works seamlessly. User Panel on the lemonink.co is clear and intuitive too. What’s more, the support team answers ultra fast and is very helpful 🙂

We have been using Lemonink to protect the books of our publishing house, and it works very well. Simple to integrate and best of all, whenever there is a problem, let’s say a document is too large, the support team answers very quickly. We are happy to work with a very responsive support team. Not easy to find on WordPress.

I’ve just started using this plugin and service and I am super happy with it. The support and response time of Piotrek (one of the developers) was super fast and very helpful. This was also the exact kind of social DRM I was looking for: simple, subtle, affordable and easy to implement. Happy I found them…
