SEO: Flash Is Evil. Five Big Reasons Not to Use Flash
There are many reasons not to use flash, here I have listed a few of them.
Flash is evil
Building Flash-powered websites is wrong. Storing your content in Flash movies is wrong. Implementing site navigation in Flash is wrong.
Then why are there so many Flash sites? They look pretty with all those neat vector graphics, gradients, animations and cool sound effects. Flash is the favorite toy of big designer studios and numerous amateur graphic artists alike. Flash is visually attractive, and in general attractive websites are more successful than the ugly ones (notable exceptions: craigslist.org and plentyoffish.com). But this is not the case of Flash websites. All the benefits of the nice outlook are overridden by the disadvantages in terms of SEO and usability.
Flash requires bandwidth
Despite of the DSL Internet access being available almost everywhere, there are still lots of people surfing the Net via dialup or other limited bandwidth connection. Flash files, especially those using sound effects, embedded movies or bitmap images, can take a while to load.
Disabled back button
Some Flash designers use meta refreshes or other tricks to disable browser’s Back button. As the famous usability expert Jacob Nielsen says, The Back button is the second most important navigation element after hyperlinks. People not able to use Back button will click the third most important navigation element Ã¢â‚¬â€œ that X button in the top right. Besides, if you are going to promote a Flash site via PPC, you should know that Google AdWords doesnÃ¢â‚¬â„¢t approve pages with disabled back button.
Flash ignores users needs
Whereas the ground rules of marketing emphasize the concentration on the usersÃ¢â‚¬â„¢ needs, Flash websites ignore them. Take the infamous site intros and splash screens that are as much annoying as the 45 minutes of advertising and previews in cinemas. Or another example: the sound effects Ã¢â‚¬â€œ they are can be especially inappropriate and harmful when you are browsing the Net from a cubicle in a quiet office or from home in the late hours.
Problems with third-party Flash developers
Unless you do Flash yourself, you might face some serious troubles with developers. Some of them code their project to prevent them from editing, thus making you to hire them over and over again as you need to do even the smallest modifications. Aaron Wall in his SEOBook (a highly recommended SEO reading) describes a case of a Flash developer who disabled the back button and then asked $4000 from his client to re-enable it, although the problem was caused by his own incompetence.
Search engines do not like Flash
And perhaps the most important: not every search engine is able to crawl and index the content of Flash movies. Even those that can often do it with errors. Even though Google has a limited access to Flash within Websites, Flash-Objects themselves are code-wise not that well-structured like HTML-Documents.
This is a big issue, as Google can’t find the context of Information stored in Flash within the HTML-Code. This is in particular the case of a website fully implemented in Flash as a single file. Search engines just wouldnÃ¢â‚¬â„¢t be able to direct visitors to the proper page within that file.
What is Flash really good for? Banners and ads Ã¢â‚¬â€œ it provides far more useful features then the traditional gif animation. Online games Ã¢â‚¬â€œ remember the Ã¢â‚¬ËœYeti SportsÃ¢â‚¬â„¢? Flash technology Ã¢â‚¬â€œ the Flash videos â€“ for video blogs.
If misused, Flash breaks our definition of using a Web-Browser
Functions like going back and forth, copy and pasting and bookmarking won’t work within Flash. This shows, that Flash is not only a problem for disabled users, but also in everyday use. The conclusion to all this: Flash is evil!
