Add a META.json to the distribution. Your buildtool should be able to autogenerate it.

Add =head1 LICENSE and/or the proper text of the well-known license to the main module in your code.

Add 'use warnings' (or its equivalents) to all modules, or convince us that your favorite module is well-known enough and people can easily see the modules warn when something bad happens.

Error: Net::Google::Analytics, Net::Google::Analytics::AccountFeed, Net::Google::Analytics::AccountFeedEntry, Net::Google::Analytics::AccountFeedResponse, Net::Google::Analytics::DataFeed, Net::Google::Analytics::DataFeedEntry, Net::Google::Analytics::DataFeedRequest, Net::Google::Analytics::DataFeedResponse, Net::Google::Analytics::Dimension, Net::Google::Analytics::Feed, Net::Google::Analytics::FeedRequest, Net::Google::Analytics::FeedResponse, Net::Google::Analytics::Metric, Net::Google::Analytics::XML

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.

Add a 'repository' resource to the META.yml via 'meta_add' accessor (for Module::Build) or META_ADD parameter (for ExtUtils::MakeMaker).

This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.

Add SECURITY(.pod|md). See Software::Security::Policy.
