To use Flash or not?
There are few things to consider when thinking about using Flash on your website: your budget, Search Engine Optimization (SEO), and your industry type.

Consider your web design budget
A standard website can cost you anywhere from $500 to $3000 and that doesn’t include Flash. There are many factors that go into the price of a website, but Flash would be considered an added feature and therefore would cost you hundreds extra. So, when considering including Flash on your website, first take a look at your budget and see if you can afford it.

SEO and Flash
There are a couple of reasons why you would like to have a Flash site for your business, it grabs visitor’s attention and it’s interactive. On the other hand, you might not want to have a full Flash site for your business because they’re made up of graphics and graphics are not search engine optimized (SEO). It is very important to have your website be SEO friendly, but that’s a different topic. Your website can of course have Flash elements like those shown in the examples above.

Is your business in an industry that’s ready for Flash?
The type of industry that your business is in has also a factor of how much Flash on your website you should use (if you decide to use it). For example, if you’re in a Health Care industry your website doesn’t need any Flash, but you may still use Flash elements minimally. The main reason for this is because the visitors that would come to your website would not typically wait for the Flash to load, they just want to get in, find what they’re looking for and leave. But if you’re in the Arts and Entertainment industry, than it would be good for your website to have at least some Flash in it. I would at least suggest for your website to use a Flash photo gallery. When people come to an entertainment type of website, they are more interested to interact with your website and take their time to view things such as slide shows.

So before you consider to have your website designed in Flash, first thing about your budget, your search engine ranking and your industry type.
