Use an effective marketing principle

A – Attention (Awareness): attract the attention of the customer.
I – Interest: raise customer interest by demonstrating features, advantages, and benefits.
D – Desire: convince customers that they want and desire the product or service and that it will satisfy their needs.
A – Action: lead customers towards taking action and/or purchasing.

Nowadays some have added another letter to form AIDA(S): S – Satisfaction – satisfy the customer so they become a repeat customer and give referrals to a product.

BOSCH-Formula

• Be inquisitive, ask open questions
• Offer solutions, talk about the end result benefits for the customer
• Stimulate the senses, let the customer test your product
• Cross your sales, think of all the necessary accessories
• Hit the closing point; sell when the customer is ready to buy
• Experiment with few colours
• Dark body copy on white background and light body copy on black background are passive
• Vibrant colours can help to highlight some specific elements of the site which you’d like to point users’ attention to
• Sometimes it’s useful to pick a moderate number of colours and use them efficiently

Strive for Balance

• Provides users with some sense of closure
• Gives the feeling of permanence and stability.
• Balanced designs are easier to digest and to understand; because they create a visual hierarchy which clearly displays what is more important on the web-site and what is less important.

Strive for Clarity

• Clarity of both layout and presented information should be given one of the highest priorities in the design process.
• If there is any chance of misunderstandings and ambiguous titles make sure to get rid of them or specify explicitly what is meant
• Being more specific is usually better than being less specific
• The more organized your categories are, the easier it will be for your visitors to find their path through your site
• Address your users’ needs
• The primary task to comfort your visitors by addressing their needs
• Providing them with sufficient clues for seamless and intuitive navigation
• To maximize your exposure you have to consider various types and profiles of your visitors
• Identify major groups and offer each group the functionality its members would be comfortable with
• Integrate multiple levels of user interaction in one single design layout
• Important to enable frequent users to use shortcuts — to increase the pace of interaction use abbreviations, special keys, hidden commands etc.
