How important is it for a business website to be optimised for mobile?
It is absolutely critical. There are almost no cases left (low percentage) in which a website would not benefit from being mobile optimized in some way. Even businesses with a low percentage of mobile use in their target market retain some benefits.
Should contact details be displayed on every page?
That depends on the site’s goals. If your site’s entire purpose is to drive email or phone contacts, then yes, I’d put whichever you need in either the header or footer of every page. If not, that may be overkill.
How do you design colour schemes that fit well with the image of the business while being attractive and web friendly?
I don’t, usually. When I’m involved with this part of design, I guess usually the client wants the site to generally “match” their pre-existing scheme. A proper graphic designer could answer this question better, undoubtedly.
What can easily make a web design go bad?
Many, many things. Focusing on your own wants/interests in the design. Catering to the client’s every whim without giving them sound advice. Hiring or outsourcing bad designers to do the work or help you with it. Working on too little sleep. Not taking mobile users into account. Not considering the front end developers who have to build the design, and their requirements. Tons of things.
How important are images and graphics in a web design?
Pivotal in some cases, not so much in others. If you’re making a minimal app that doesn’t really need to attract people based on its appearance, then very little importance. If you’re making a news app that is competing with a bunch of big names, or a local business website that’s trying to be eye-catching, then those things are very important.
