The article you linked to says it all.. “The main problem with Flash is that search engines don’t yet understand it, and probably won’t in the near future. Flash includes logic and can take input from the visitor, but search engines are designed to handle static content. Flash is actually a running program, so it’s much harder to analyze than plain HTML code.”

If you’re going to create a flash based website which acts as a virtual brochure, then go with that. If you want to create a website that is search engine friendly, then AVOID FLASH AT ALL COSTS!!!

An SEO friendly website uses HTML techniques. Proper structuring and designing your HTML content is the ultimate issue for SEO friendly websites. I am expanding and adding into factors that have been mentioned;

•Use HTML page content that is informative for visitors and also useful for search engines. Put keywords in your content wherever possible and avoid repetition and Spamdexing
•Optimize graphics; use Alt Tag
•Use Bullets & apply Text styles like (bold, italic)
•Try to put links of other important web pages on main page

I partially agree with Kelli Myers that Flash based websites attract more visitors. Generally, people are reluctant to visit fully featured flash websites because they take much time to load in browsers or sometimes flash plug-in is not found on visitors end so another problem arises.

But if we look on other side of picture, it contributes only for conveying message. Designer should make it brief & comprehensive. By putting some emotional touch it can work better. Yeh, if you are targeting kids or teenagers, then I emphasize to use flash for attraction.

Though there are some SEO tools and side-ways available for Flash but they are not very effective. In the end crawlers face problems while indexing Flash pages. If you think Flash will attract more visitors (that happens 1 or 2%) or you really need it, then use Flash content within HTML pages, apply targeted keywords in Title, Meta Tags and page names. Furthermore, add description about Flash content in HTML so that search engine can crawl. But it is not compared to a true search engine friendly website.

It is recommended that if you are considering your website to work as search engine friendly then “Do not develop a 100% Flash site. It is best approach to develop a website with more HTML text and appropriate ratio of graphics; that makes it attractive for visitors and search engines.
