Hello I just started a website while studying for a year and a half how to make money on it. So I got everything down pack on the whole google adsense thing and affiliate marketing. I hear content is king so if my site looks cool with flash and is filled with keyword rich content, I would get more traffic to it right? My site would not have to be like those cookie-cutter ones but a nice flash site as to how everybody has high-speed internet now.
Flash is considered very poor for SEO. "Good Content" from an SEO perspective is HTML with natural distribution of keywords. Content may be very good but not attract SERPs because it isn't presented in a search-engine friendly format. Also avoid frames and images, as spiders will not be able to read text embedded that way.
make sure you update the site often. You also want to be careful about making the site too keyword rich. A good designer should be able to give you a seo optimized site. infinfx.com
Be careful with flash as it has no SEO value and cannot be read by spiders and bots. For instance if you use flash for your navigation menu, Google and the other engines won't be able to follow the links to your other pages. You can, of course, put a footer navigation. There are so many variables in getting high traffic. Good amount of quality content is just a piece of the complicated puzzle.
A mixture of both will be good. Its good that you are creating site more for the users instead of search engines but it will be search engine that will be bringing traffic to you (assuming you won't be advertising). You will have to use SEO if you won't to run the site. Using HTML or any other format that spiders can read will be good.
