Things to consider when evaluating a web developer:

• Look at their folio / past work
• Check testimonials and references, 
• Do they have a clear project methodology, 
• Can they offer all services you need?  

Look at their folio

The best way to choose a web designer is to first have a look at their folio to make sure that their designs are professional and flexible; Most professional design studios will be able to customise designs based on your market and emphasis your competitive advantage. Some agencies do this better than others of course. Other things to consider when looking at a design firms folio is to see whether the message is clear? What is it that the business is trying to communicate. Visit the website in question and check that it is easy to navigate to find specific information.

Pricing

Website development prices vary wildly, but it is difficult to compare prices.  It is unwise to base your decision solely on price. It is best to get a feel for the prices then work out what you are prepared to spend and go with the agency that best meets your needs, advise them of your budget and see what you can get for that price. A word of warning, do not choose the cheapest website developer. A good website developer will maximise your spend and will be able to advise where best to invest and in turn how to maximse your return on investment. A good website will generate good quality leads and communicate your message. A cheap website will turn potential customers away.

Service / Trust

Check a website developers references and testimonials. Do they have good testimonials, can they provide references?   Make sure that you ask the references that the service was good, in particular the after project service. You don't want your web developer disappearing over night.  Do they have an established office and the ability to meet your needs.

Do they have a clear project methodology?

Can the agency explain clearly how the project will progress and how long it will take? A good agency will keep you updated and advise what steps will be completed and when.

Can they provide all services?

To avoid dealing with multiple suppliers, it is advisable to engage an agency that can cover all areas of the website development process including. Design, development, CMS, hosting, domain registration, SEO, site promotion, copywriting and support.
