Think about what keywords you want to rank for, there
is no right or wrong. Go big and include those high
volume, challenging keywords, as well as the low
hanging fruits and you’ll start seeing results on rapidly.
SEO is a long game, so make sure the keywords cover
the range from tried and tested to trending, or will trend.
Including a mix of keyword volumes in month one will
also help you to watch the site grow, while giving insight
into what needs more effort
