Optimizing Flash Files For The Search Engines
What’s a Flash Movie?
A flash movie, or shock wave file (SWF), is the file format printed when a Flash movie is exported. A SWF file will also be exported by many different Macromedia or Adobe Products. The SWF is usually an animation, dynamic menu, or highly interactive net-based application embedded into an HTML page. Flash files, when exported correctly for the best internet-based optimization, are compressed, so making their file size lightweight. The SWF format is right for presenting vector-primarily based, interactive and animated graphics with sound and video for the web. Vector pictures are ideal because they can not “pixilize” if stretched or compressed. Flash files will additionally contain text that will be animated, static or dynamically populated from external sources, such an XML file or a database. Text embedded in an exceedingly Flash file, for many years, could not be read by search engines. However, recent updates by Macromedia are creating this a possibility.
Issues with Flash and Search Engines
Historically, it has been troublesome to induce Flash content indexed and ranked by search engines. In the past, search engines, such as Yahoo and Google, failed to spider Flash content as they could not scan the compressed file and abundant of the text within the SWF appeared as graphics to the search engines.
The main page of a web site, if Flash-based mostly, rarely ranked well, unless off-page factors like link popularity or link reputation were sufficient enough to carry the page. Flash files that were indexed by Google, Lycos and different search engines, that didn’t have any text or key words related to them in the search engine results pages (SERP).
Techniques Utilized in the Past to Build Flash Visible to Search Engines
Ancient search engine optimization (SEO) techniques would facilitate your website get indexed, however not rank for search terms. Each net web site wants at least one HTML page to load into a browser. For a internet website developed utterly in Flash, developers would embed their flash files into an HTML document and then produce the meta tags in the head section of the HTML file. They’d also add descriptive HTML text for the search engines in the body section of the HTML page, then use CSS positioning and percentages to load the Flash move during a pixel-good location over the top of text. This particular technique ought to not be used any more, as search engines will view this system as an try to add hidden text, and hidden text will incur a penalty from the engines.
Another technique which may help your Flash ranking is to not compress your SWF files. One in all the explanations search engines could not scan flash files within the past is {that the} files are compressed. If the SWF is uncompressed, search engines will scan the static text. This technique can be accomplished easily. Upon exporting a Flash file, you’ll be able to set the compression to “not” if you want your text within the Flash movie to be readable by the search spiders. However, this is not a smart follow, as not compressing your SWF will increase the file size, consequently negating a major benefit to Flash file – a light-weight file.
What Macromedia has Done to Make Flash A lot of Visible to Search Engines
Within the past, Google did index Flash files. Anyone will check this reality out by looking out in Google using the “filetype” operator to restrict your search. As an example, attempt the subsequent search: “Casino Games filetype:SWF”. The SERP will embrace over 200 Flash files, which are indicated by the “Flash” text to the left of the listing.
Some search engines are now using the Macromedia Flash Search Engine SDK (Software Development Kit). For example, Google, AllTheWeb, Lycos, and other sites can readily display links to Flash content. Flash Search SDK is and open supply tool that permits search engines to modify it to suit their needs. With this level of customization, it is possible that the key search engines will modify SDK, making it tough for website house owners to understand specifically what info can be pulled out of the SWF file or how it can impact actual rankings.
The Macromedia Flash Search Engine SDK can be found at
http://www.macromedia.com/software/flash/download/search_engine. In keeping with the Macromedia/Adobe internet website, The SDK includes an application named ‘swf2HTML’. Swf2HTML extracts text and links from a Macromedia Flash SWF file, and returns the info to an HTML document. Swf2HTML is provided as a compiled application and as a static library for linked library implementation. SDK can interoperate any links that are within the action script so long as adhere to the following criteria:
• The link is contained among single quotes (‘ ‘) or double quotes (” “), and
• The link prefix is HTTP, and
• The link suffix is HTM, HTML, CFM, SWF, JPG, JPEG, MP3, or WAV
By default SDK extracts the subsequent text from your flash file:
• Text on stage in the present movie (dynamic text, static text, or input text that has an initial value assigned)
• Text on stage in an exceedingly movie that is referred to as with movieClip.attachMovie()
Google can see sure text in Flash files currently, however how and where bound text gets extracted depends on what you are doing with that text in the Flash presentation. For instance, text that is static or is employed in a motion tween can be read as one instance with SDK. However, some animation involves converting text into a image and then using multiple copies of that image to attain a desired effect. This can produce duplicate instances of your text to the SDK output, that might be viewed as duplicate content and not given a lot of importance by Google.
Using the SDK tool, any developer will get the text output from the SWF and see how search engines read the extractable text of any SWF. On a Windows operating system, you can move to the DOS prompt and execute the swf2HTML application terribly easily. The subsequent is an example from the DOS prompt: C:sdkswf2HTML -o test.HTML C:sdkcrt_webfilestest.swf
Search Engine Optimization (SEO) Techniques Used Traditionally for Flash
Every Flash file will not need to be uploaded independently and called as a SWF file; rather a Flash file can be embedded in a commonplace HTML document. One among the most effective techniques is to make a modular net site, where there are many Flash files which make up the web page combined with customary HTML elements. A hybrid website such as this, works particularly well, if your navigation uses ancient HTML links. You’ll use cascading style sheets to give the appearance of flash text links. This sort of hybrid website can invariably rank better than an all Flash site – all other factors being equal. It is also vital to own your HTML page title correct, no matter something else. Many search engines observe meta titles first. In addition to the page title, you’ll add meta tags to the head of the file. Outside of the actual HTML page, off page factors are important. There was abundant written in recent articles that reciprocal links don’t seem to be as important any longer, however certainly, one-method links pointing to your website from highly relevant and high ranking pages will increase your page rank. In addition links from outstanding directories, such as Yahoo and Business.com, placed in the foremost relevant classes can help. One-manner inbound links from relevant sites remains the most effective manner to extend your ranking with or while not Flash.
There are programming techniques that work whereas within the Flash authoring environment. While you are in the Flash authoring surroundings, together with your FLA open…click F12. It will generate the HTML page for you. Examine the code of the page; it creates a place for you to place the text and URL’s utilized in the Flash.
New SEO Techniques for Flash
Today there are many techniques which can overcome the restrictions of the past, where Flash files are concerned. With the inception of the new Macromedia Flash eight, there are techniques that can be implemented to greatly increase the power of search engines to index Flash files and even rank for key words.
Within the past, SWF files may not have titles. This is often one vital reason why Flash files didn’t rank well. This title limitation has now changed. Flash eight will enable you to input meta data. Flash eight defines two fields with meta knowledge for all Flash files. These 2 fields are Title and Description. You’ll be able to access the meta knowledge fields under Document Properties. To add meta information, fill within the text fields and therefore the search engines will apprehend what data to display concerning your Flash file.
SDK is fairly intelligent in terms of recognizing text and links that are embedded within the file. If text is static or dynamically driven by an XML or text file, it will be read. If your content is dynamically driven it should be done therefore using the newest version of ActionScript 2.0. The SDK will parse ActionScript two byte code looking for links. It may conceivably notice the link to the XML file that means and hand it back to a quest engine.
As referenced earlier, certain text will be modified into a symbol instead of strait text. For instance, a button would possibly have the text output two or three times. Alternatively, tweened text has motion associated with the action. Tweens end in a single prevalence in the output from the extraction process. You must additionally notice {that the} link text within the Google results page is identical to the first few lines of text at the terribly prime of the text extracted by swf2HTML. Armed with the knowledge of how SDK parses your content, you’ll manipulate text in your Flash Movies a lot of fastidiously and create your content key word dense, simply indexable, search engine friendly and, with a little more skill, even optimized.
What’s the gist of all this? Flash continues to be not the most effective answer for a pure SEO-based project, however their are large leaps forward by each the search engines and Macromedia in permitting your flash files to be indexed and even rank for the key word phrases you covet.
