A visitor arriving on a new website is sceptical, of course they are.  Your job is to convince them of the validity of your proposition.

So ensure that the second thing they read (after your proposition/sales message headline) is:

1. A positive, relevant and recent client testimonial (or better still, a videoed testimonial)
2. An engaging case study.

Also ensure that you're using Google (and other) Reviews as additional support to your professionalism.
