As an actor, the main goal of your portfolio website should be getting you work. You want casting agents and industry people to find your head shots, resume and reel as quickly as possible. Here are ten common mistakes to avoid and what you can do to improve your website usability.

1. Flash Websites - One reason to avoid creating a Flash website is that the content on your site will not be indexed by search engines. If you want people to find you, design your website using standard HTML. An HTML website will load faster. If you feel Flash is necessary, add Flash elements to your website instead.
   
2. Resume - Aside from putting your resume on your website, make it available to be downloaded in PDF, Word Document and Plain Text formats. Having your resume on your website doesn’t mean it will print properly so providing your resume in a format that is convenient to your visitors is important.
3. Consistency - Make sure the colors, font choices and layout of your website are consistent. If someone visiting your website hasn’t met you, you don’t want to make a chaotic looking first impression.
4. Professionalism - Your actor portfolio website is your professional calling card. Family photos, funny youtube movies, and outrageous friend comments are fine for your myspace page, but with your online portfolio keep the focus on your image, your body of work, and your contact information. You. You. You.
5. Contact information - It may seem obvious but there are plenty of actor portfolio sites with little or no contact information. Make sure your phone number, your email address, and any management information is readily available on your website. Avoid using a contact form because it’s an unnecessary barrier between you and people wanting to offer you work. If you are weary of giving out your digits because of stalkers and love-struck fans, use a service like grandcentral that will forward calls to your existing phone line.
6. Hijacked Websites - All too often you hear stories of people having their sites stolen from them. When you register your domain name, use a credible company like Register or Network Solutions. Make sure the name is registered to you, at your address, and paid for with your credit card. If you have a hired a designer, a professional website designer will know to register the domain in your name and if necessary, they can add themselves as a technical contact.
7. News - Add a news page to your website or have a space on your home page that will allow you to keep industry people up to date on your current projects.
8. Music - Another big mistake people make is having music play on their website. Visitors are at your website looking to find information about you, not to hear the latest Cold Play song.
9. Pop-up Windows - Avoid these like the plague. Aside from being a really dated technique, pop-up windows are blocked by most web browsers for security reasons.
10. Website Templates - If possible, avoid using templates from website mills. Often times the template’s navigation is unintuitive, pages can’t be optimized for search engines, and generally speaking, the templates look cheap because of dated font choices and limited layouts. Like anything else, you get what you pay for. There are lots of talented website designers out there who can create for you a professional website for a reasonable price. If you see a website you really like, contact the person and asked them who designed it. Ask friends and colleagues if they can make any recommendations as they will generally be able to recommend a great designer to you or, at the very least, tell you who to avoid!
