To create a successful website design, you must first have a strategy.
What is the stated purpose of your website?
What do you intend to achieve?
Have you assessed your direct competition and what flaws they have?
Who is your target audience?
What do your prospective customers want and what do they expect to see?
Is your web design structure and content relevant?
Does your web design promote a solution in a sufficiently robust way?
Have you incorporated local SEO into your web design?
How persuasive is your marketing copy?
Are you targeting the right keywords?
Try to make things as easy as possible for web users; the design must be user-friendly. Nobody wants to be confused about where to go and what to do on your website.
