You need a header to grab attention like a newspaper does. 
Way too many businesses try to get 'cute or clever' and that doesn't work.
Because, if I can't figure it out.. then I will move on and not read any more.
We get bombarded with messages all day long and I want something easy to understand.

You need to offer something... like a savings in frustration, a simple way to lose weight,
tips to a beautiful garden, etc. The last thing I need is a riddle to figure out what you offer.

We like people that are clear.
We enjoy the pleasure of understanding them.

So, take a look at the tagline in your header..
It must answer the question 'If I do business with you, I get this'

Nobody wants to hear about you in your 'about us' section.
What? After all, it's about us, right? What customers are interested in, is
How are you going to work for me?

Don't spend time telling folks how your grandpa started the business
years ago and how you took it over..  blah blah blah
Tell them instead how you love gardens and everyone should have a beautiful
one and how that gets you up and motivated in the morning

It's okay to tell them you went to school, but tell them you went there to solve this problem.
Be customer oriented, not company oriented.
And they will love you.. why? 

Because they are hurting and looking for help.
** They are looking for someone who's story is about solving their problem.
