I so love to hear:
"but my customers won't buy from me by looking at my website, I
know I just need to have one."
So what's the point?
If people search and find your site, chances are they want your product - they will contact you if not through the lovely contact page you had designed, they will ring from the phone number you placed in an easy to find area on your page.
Example:
I submitted my site to google, created all the bit's and bobs to get a nice high ranking. I got to page one when people searched for 'freelance web design staffordshire' (as I live in Staffordshire and I am a freelance web designer - get it!).
Last week I had three phone calls/emails requesting I give them a visit, all I have to do is turn them into customers. That's what I love about this stuff, I didn't have to trawl through the phone book make lots of expensive cold calls to people "who are not interested" or already have it covered. They looked for me as they needed my services.
Don't loose you potential customers - get found!
