Lousy aim
You cannot market your SaaS, product, service, app or website to everyone.
And you shouldn’t even try.
Your marketing, especially at the start, should be narrowly focused.
So narrow that if your marketing were a stone you had to throw at your target person, and every person on Earth gathered together in the same location, you stand a reasonably good chance of missing them.
It might be a bad metaphor, but it made you stop and think.
Which is precisely what you should be doing with your marketing.
Identify the exact person you want to market too.
Address them personally as though the message was for them and only them, hand-delivered by a professionally attired courier.
Make your marketing about that.
