Add a Changelog (best named 'Changes') to the distribution. It should list at least major changes implemented in newer versions.
Add a README to the distribution. It should contain a quick description of your module and how to install it.
Remove the POD errors. You can check for POD errors automatically by including Test::Pod to your test suite.
Error: WWW-A9Toolbar-0.01/lib/WWW/A9Toolbar.pm -- Around line 506: You forgot a '=back' before '=head2'
Add a META.json to the distribution. Your buildtool should be able to autogenerate it.
Define the license if you are using in Build.PL. If you are using MakeMaker (Makefile.PL) you should upgrade to ExtUtils::MakeMaker version 6.31.
Add 'use warnings' (or its equivalents) to all modules (this will require perl > 5.6), or convince us that your favorite module is well-known enough and people can easily see the modules warn when something bad happens.
This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
Add all modules contained in this distribution to the META.yml field 'provides'. Module::Build or Dist::Zilla::Plugin::MetaProvides do this automatically for you.
