What qualifications should you look for in a web designer or developer?
As web design is a totally unregulated industry, generally qualifications are irrelevant to who you choose to use and not correlated to the level of service you could expect. It is more about their track record in achieving similar success for you as they have for other clients, rather than how many letters they have in their title.
As mentioned above, it is important to make sure they have a body of work (portfolio) that you can access and take time reviewing. It is also a good idea to look for any testimonials from previous clients. However, it is still worthwhile to contact several clients for more detailed information if desired. It is important to feel comfortable working with a designer or developer.
Be willing to give them a list of your needs or more formal requirements. This can give them the ability to provide you a more accurate quote. Also, if you are unsure of what you want to do, start out giving them a smaller job. Ask them to review your current website (from a design and/or development perspective). This way you can hear what they think needs improvement as well as how they would potentially make that happen.
Also, be sure to discuss your needed timeline. Many business owners disregard having a time line in mind, however, the turnaround time can greatly impact the price. Rush work will always cost a premium.
Lastly, keep an open mind. Designers and developers (myself included) prefer to have the ability to produce great solutions. Micromanaging these roles will not produce the desired results. It is okay to ask for changes, but be specific when giving feedback so they know what needs changed. Remember, hiring the services of a designer or developer is no different than going to see a doctor or having a plumber come over. They are the experts so show that you trust their judgment. Would you second guess a doctor telling you about a procedure or a medication? If your drains were backed up would you tell the plumber he doesn't know what he is talking about? The answer to both of those questions is hopefully, "No".
In that same light, be reasonable with a designer/developer. Remember you hired them for a reason. Also, designers and developers talk. If you are labeled a problem client, you'll likely have trouble landing any other designer or developer in the future. We don't like to work with frustrating people if we can avoid it.
It depends what you are wanting.
If you are wanting a simple website (small business website, personal website), contact the designer/developer's previous clients and find out how happy they were with their services. You can also find out if they have set up a CMS style website so you can make simple changes yourself (if that is what you are wanting).
If you are thinking of developing a website that has more complex functionality, you'll be wanting a business that has a team of people, and do the same thing. Find their previous customers (whom they have completed work for) and ask them what they thought about their services.
If your website is going to be used to generate leads or revenue, it needs to be designed and developed with that in mind. The agency you use (or solo person) should have experienced in this and basic SEO. IF you rank for keywords, they should ensure that you will continue to rank for those and have that included in their proposal. Someone who does competitor research, and takes the time to learn about your business. Otherwise, your website wont be unique it will look like every other website. Hope that helps!
