One of the secret sauces to consistent success is to data mine competitor reviews. Read 100 customer reviews belonging to your competitors on Amazon, Google, Facebook, Social media comments, etc.

Note the trends and keywords or phrases that appear often, positive or negative, and determine the frequency of these phrases.

Frequency: the number of times this phrase was found out of 100

Positive or Negative: is this comment or review point favourable or unfavourable

Intensity: How powerful is this comment? MINOR (easy to forget), MODERATE (noticeable) or MAJOR (life changing)
