Optimizations

Plugin configuration 90% from 29 tests

readme.txt 94% from 16 tests

Perhaps the most important file in your plugin readme.txt gets parsed in order to generate the public listing of your plugin
These attributes need your attention:
  • Tags: Too many tags (12 tag instead of maximum 10); only the first 5 tags are used in your directory listing
The official readme.txt might help

contact-form-lite/easy-contact-form.php 85% from 13 tests

The principal PHP file in "Contact Form Plugin" v. 1.1.23 is loaded by WordPress automatically on each request
Please take the time to fix the following:
  • Description: Please don't use more than 140 characters for the plugin description (currently 349 characters long)
  • Main file name: The principal plugin file should be the same as the plugin slug ("contact-form-lite.php" instead of "easy-contact-form.php")
