15 seconds, that is all you have to get the attention of a new visitor. So what does it take?
On this occasion I'm going to ask you to imaging you are you, in your own shoes as it were. Imaging you're in need of a photographer for your daughters wedding. Now go and look for a photographer on Google. There's quite a few, so look at some of the websites. Which one got your attention?
I expect it was the one that looked professional, didn't try and fill the home page with everything and, most importantly, it got your attention.
As to whether they were a good photographer or not is another matter. But that photographer got you taking the bait. There's no fixed formula for this but looking professional and standing out from the rest is always a good start.
