Biggest opportunity: “delivery tip”, “extra charge” and “surcharge” aren't earning a slot. You list them, but you're not in the first 24 results for those searches. WordPress.org counts only your first five tags, so free the slot for a search you can win.

0.4%

of downloads still active

At least 10 of 2.5K lifetime downloads are still running, below 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.

High removal-risk signals

63/100

Maintenance and integrity signals that tend to precede a WordPress.org removal. Not an official status, a heads-up to act.

  • Long abandoned. No update in 8+ years — the top precursor to removal once a vulnerability is found.
  • Compatibility drift. Tested only up to WordPress 4.2.39, well behind 6.8.

Mixed CompatibilityBroken updates

One reviewer hit a fatal error on activation, then found it was an old PHP version on their server and the plugin worked fine once updated, though they'd still like the compatible WooCommerce version stated up front.

Directory rank

Ranked about #30,100 to #45,000, alongside the other plugins at 10+ installs. Plugins with the same install count swap places between wp.org requests, so this is where most of them sit. Checked monthly, last on 21 Oct 2026.

Update activity

Downloads in the last 30 days for every 1,000 active sites.

Not enough installs to measure. This needs at least 100 active sites; below that, a handful of downloads reads as tens of thousands.

    UPDATE: This plugin requires PHP 5.6 minimum. The issue described below was due to a very old server running 5.4. After updating the version of PHP this plugin was able to be activated and performed as expected. Using WP 4.7.6 and WooCommerce 3.2.1 The plugin triggers a fatal error on activation and cannot be used. Author needs to state compatible WooCommerce version in addition to WordPress version. Fatal error: Can’t use function return value in write context in /wp-content/plugins/additional-charge/class.additionalcharge.php on line 71 This topic was modified 8 years, 9 months ago by Rae Carlson.

Readme readiness

1 of 8 pass · checked 24 Oct 2026

Can an assistant quote this readme? Eight deterministic checks over the wp.org listing, no model involved.

  • ! Says what it does Short description is 10 characters, too short to say what the plugin does.
  • ! Has a FAQ Only 1 question in the FAQ; 3 or more gives an assistant something to match.
  • ! FAQ asks real questions 1 of 1 FAQ entries are headings, not questions ("Installation Instructions").
  • ! Names who it is for Never says who the plugin is for or what they use it for.
  • ✓ Names what it works with Mentions WooCommerce.
  • ! Headings and lists 1 heading and 0 lists; assistants quote headed sections and bullet lists, not paragraphs.
  • ! Enough to quote 244 characters of description; under 1,000 there is little to quote.
  • ! Tags match the text Only 2 of 5 tags appear in the text ("delivery tip", "Extra Charge", "surcharge" missing).
