Biggest opportunity: Swap “ecommerce”, “tax” and “vat” for “vies”, “locker” and “billing address”. “ecommerce” isn't earning its slot: you're not in the first 24 results for its own search. “vies” sits at #4 untagged, close enough for a declared tag to move it up. “tax” isn't earning its slot: you're not in the first 24 results for its own search. “locker” sits at #12 untagged, close enough for a declared tag to move it up. “vat” isn't earning its slot: it only gets you to #18. “billing address” sits at #13 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 →4.5%
of downloads still active
At least 5K of 110.4K lifetime downloads are still running, above its category: the median eCommerce plugin keeps 1.4%, across 5,139 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 10 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.

Avaliação actualizada em Dez 2020 🙂 ** Quando for possível tornar o NIF campo obrigatório através de uma “checkbox” e fazer a sua validação automática darei 5 *****… 🙂 Até lá vou usar outro plugin que faz mais ou menos o mesmo. Actualizar os ficheiros do tema como proposto nas FAQs é pouco recomendável, como se sabe. Criar um child theme só para isto, não vale a pena… This topic was modified 5 years, 7 months ago by evita.
