At a recent Legal Marketing Italia seminar, the question arose as to why a company’s web site doesn’t rank well, even for the company’s name. In Italy, the most common problem encountered with websites is the use of Macromedia / Adobe Flash to develop most or all of a company’s website. This case was no exception.
Update: Google has announced improved crawling support for Flash sites. Our related article Why Flash is still bad for SEO and the Web explains that nothing has changed – the best websites should still avoid Flash. (2 July 2008)
Italy has a strong history of excellence in visual communication, including graphic design. Indeed, the very successful New York City subway signage was designed by an Italian. Many Italian graphic designers have worked on web sites, adopting Flash as their preferred technology when moving from the printed media to the web. Flash allows “pixel perfect” control over web design, including font specification.
Unfortunately, Flash technology is a poor choice for most commercial web sites. A proprietary technology, Flash breaks most web standards and conventions. While Flash sites are generally beautiful to look at, the fail to meet a number of minimum criteria for business-oriented websites.
1. Information embedded in Flash is often invisible to search engines.
Most Internet navigators begin a web session with a search engine. Even when they know a domain name, they start with Google or a similar search engine. With all the possible confusion of .com, .net, .eu, it’s better to trust Google to find the “right choice”. As search engines are the gatekeepers to the Internet, it is imperative that companies maximize their natural visibility in search engines.
Search engines work by scanning information on the web, processing it, and retrieving the best match for each user query. Search engines are fine-tuned to process text, semantically wrapped in tags. The markup in hypertext markup language is our specification of a document title, headings, paragraphs and links – structural meaning which helps search engines place appropriate importance on each text element.
Information hidden in graphics formats, such as Flash, is difficult, if not impossible, to find and process. While search engines such as Google try their best to extract links and textual content buried in Flash objects, the process is far from perfect. Sites constructed completely in Flash often offer very little textual information – consequently what information a search engine does find ranks poorly. Even sites partially constructed using Flash often “hide” their internal site links using Flash based site navigation.
Search engine optimization practitioners can help companies with Flash based web sites overcome Flash limitations without violating search engine guidelines.
2. Website reporting on Flash navigation is problematic and cumbersome.
Web Analytics systems help marketing professionals evaluate website visitor behavior in and around a website, providing actionable information valuable in improving a website’s business performance.
Web server log based systems are able to track when a Flash object, typically a swf file, is viewed. They are not able to track navigation within a Flash object – so if a site is composed of one Flash object which contains multiple site sections, the Web Analytics system will see a swf download, but will have no idea which parts of the site a visitor viewed nor where the visitor abandoned the site.
In the real world, this approach breaks down very quickly. Web Analytics tagging is often an after thought. Flash ActionScript coding adds extra implementation cost and complexity. Flash designer(s) are often unfamiliar with Web Analytics requirements and thus don’t consider Flash events tagging requirements during site design. Implemented tag verification is a tedious process as it requires waiting for data to appear in the reporting system – hours or days later. Flash does not provide referrer information, making it very difficult to track navigation paths.
3. Flash breaks web usability standards.
Flash sites might look great, but they start to fall apart when visitors try to use them. Consider a site for a professional services company. The site contains information about the company, its services, case studies and contact information. It is clear that the company invested a lot of time in planning and developing their web site. The site deserves an excellent rating for content and appearance.
- While navigating through the site, try to use the browser back button. Unfortunately, it is disabled.
- Try highlighting contact information to paste into your contact manger, such as Thunderbird or Outlook – you cannot.
- Try increasing the font size to make the text more readable (Firefox: Ctrl +; IE 7: “View -> Text Size”. You cannot.
- Try bookmarking a page within the site (or deep linking to a page from an external site). You cannot. Keep in mind that deep linking, the ability to link to a specific page in a site, affects a site’s visibility in search engines and the overall web ecosystem.
Ouch! These are all problems that could be avoided by using standard html and css instead of Flash. Sites that have these types of problems usually also have problems with web accessibility.
There are (too) many examples of Flash designed sites which present the same problems:
- Syneo. A context design consultancy.
- Exile Solutions. Online Professional Services.
- Studiodynamis. Audiovisual Communication for the Fashion Sector
4. Lack of consistent cross platform support.
One of the keystones of the web is that a website should work in any browser on any computer – it is openness and standardization which has made the Internet universal. Flash breaks the basic tenets of web design. While most Internet users have Flash installed – they don’t necessarily have the right version installed. Indeed version 8 wasn’t even released for the Linux platform, locking those users out of sites developed for Flash 8 and 9 (Flash 9 for Linux has finally been released, months after the Windows version).
Microsoft’s Silverlight is even worse. Microsoft only supports Windows and the Mac. Linux users are told that Microsoft partner Novell is working on Moonlight, but development is way behind the Windows version, resulting a broken website here, a broken site there…. Don’t break the web folks. (added 2009-03-23)
Mobile device users, such as Apple’s iPhone, will surely have noticed that Flash websites cannot be navigated on the iPhone… website developers can and should avoid this problem at the source. (added 2009-03-23)
5. Code embedding Flash objects doesn’t pass w3c validation.
The World Wide Web Consortium, the primary web standards organization, provides a free tool to ensure a page’s html is syntactically correct. While search engines and web browsers do tolerate bad html code, a business oriented site usually wants to minimize the risk that an improperly coded page won’t render correctly or will be rejected by a search engine’s parser. Validation of pages removes this risk.
Unfortunately, standard Flash object embedding in the current html version, xhtml, doesn’t validate correctly. Fortunately, the fine folks at alistapart have documented a solution.
6. Some users disable Flash to avoid flash based advertising.
Savvier web users have learned to disable Flash in web pages to avoid animated advertising and / or to improve page-loading times on dial-up connections. Regardless of the reason, a disabled Flash website looks much like this:
Another reason to stick with html and css.
7. Website updates continually require Flash skills
One characteristic better performing websites share in common is fresh content – they are continually updated to reflect the latest company news and industry trends. Pure Flash and Flash navigation sites constantly need to use a Flash designer every time new content needs to be integrated into the existing site. If this skill-set doesn’t exit in-house, site maintenance becomes needlessly complicated.
8. Flash breaks Search Engine Site Previews
Some search engines provide a site preview option next to search results. The preview allows a user to get a clearer idea of what to expect in the target site before actually visiting it, speeding up the process of arriving at the right result. Ask.com launched their Binoculars feature in 2004. Microsoft offered MSN Search Preview at one point, reintroducing this as Bing’s Document Preview.
In their webmaster guidelines, Bing writes
Many website designers use Flash and Silverlight-based animations to display their content. Quite often these websites don’t offer any readable meta data text, such as titles and descriptions, in the HTML source code for the search engine bot to crawl. In these cases, it can be very hard for the search engine to derive a useful website description needed to populate the result caption. The Bing team found that websites that used Flash were responsible for 21 percent of all empty caption descriptions for queries in their index. … When titles and/or meta descriptions don’t exist on an HTML page, at runtime Bing creates a best-effort caption from relevant external sources of reliable information to populate the caption with meaningful data for the searcher.
Translation: if you must shoot yourself in the foot with Flash / Silverlight, at least specify a html title and meta description to make the best of a bad situation.
So we’ve got a Flash based website. What now?
There are several strategies available for mitigating problems inherent in Flash usage. While a few have already been noted above, each situation presents its own unique issues which need to be balanced based on business requirements and website development resources. In all fairness, there are a few cases where judicious use of Flash may be appropriate, such as sites in the entertainment market that serve to support an existing brand.
