Desde hace más de 5 años, Google viene indexando documentos realizados con la popular tecnología Adobe Flash. Ya en abril de 2004 os contábamos cómo el buscador de Google comenzaba a leer dentro de algunos de estos documentos Flash, indexando el texto que hay en su interior y permitiendo que los usuarios pudiésemos localizar información dentro de ellos (ejemplo de búsqueda en ficheros SWF).

Se trataba de una buena noticia para muchos webmasters y diseñadores web que utilizan esta tecnología para crear sus contenidos en la WWW, y que veían cómo mucha de la información que ponían online no estaba disponible a través de las búsquedas en Google. Ahora, según se anuncia en este post oficial, el robot de Google ha comenzado además a seguir los links que se encuentren dentro de este tipo de documentos Flash, por lo que aparecerán nuevos contenidos y, suponemos, comenzará a incluir estos enlaces dentro del algoritmo de asignación de relevancia a los documentos.

En ese mismo post oficial, se recuerdan varios puntos:

:: Google sigue sin indexar los ficheros FLV (el formato que se utiliza en los populares vídeos en formato Flash como los de YouTube. La razón es que, como Google es un buscador de texto y estos ficheros FLV no contienen información textual, no tiene sentido indexarlos.

:: Ahora se indexan además más ficheros en formato Flash que antes Google no era capaz de hacerlo (como por ejemplo, gadgets Flash), gracias en parte a nuevas librerías SWF proporcionadas por Adobe.

:: Se recuerda a los webmasters que no deben realizar ninguna acción especial para que Google indexe sus contenidos Flash, y que el robot de Google accederá a estos documentos cuando lo crea oportuno, aunque mejorando la forma en la que rastrea la información y los enlaces.

:: Se reconoce que, aunque se haya mejorado la indexación y el rastreo de documentos Flash, sigue habiendo numerosas limitaciones como por ejemplo la ejecución de cierto código JavaScript que suele existir junto a los ficheros Flash.

A pesar de estas mejoras con la indexación de documentos Flash, nuestra recomendación sigue siendo la de, a la hora de generar información en la WWW, utilizar tecnologías abiertas y no propietarias, como el HTML. Además, conseguiréis un mejor posicionamiento en Google.

Google learns to crawl Flash

Posted by Ron Adler and Janis Stipins, Software Engineers

Google has been developing a new algorithm for indexing textual content in Flash files of all kinds, from Flash menus, buttons and banners, to self-contained Flash websites. Recently, we've improved the performance of this Flash indexing algorithm by integrating Adobe's Flash Player technology.

In the past, web designers faced challenges if they chose to develop a site in Flash because the content they included was not indexable by search engines. They needed to make extra effort to ensure that their content was also presented in another way that search engines could find.

Now that we've launched our Flash indexing algorithm, web designers can expect improved visibility of their published Flash content, and you can expect to see better search results and snippets. There's more info on the Webmaster Central blog about the Searchable SWF integration.

Improved Flash indexing
Monday, June 30, 2008 at 9:31 PM
We've received numerous requests to improve our indexing of Adobe Flash files. Today, Ron Adler and Janis Stipins—software engineers on our indexing team—will provide us with more in-depth information about our recent announcement that we've greatly improved our ability to index Flash.

Q: Which Flash files can Google better index now?
We've improved our ability to index textual content in SWF files of all kinds. This includes Flash "gadgets" such as buttons or menus, self-contained Flash websites, and everything in between.

Q: What content can Google better index from these Flash files?
All of the text that users can see as they interact with your Flash file. If your website contains Flash, the textual content in your Flash files can be used when Google generates a snippet for your website. Also, the words that appear in your Flash files can be used to match query terms in Google searches.

In addition to finding and indexing the textual content in Flash files, we're also discovering URLs that appear in Flash files, and feeding them into our crawling pipeline—just like we do with URLs that appear in non-Flash webpages. For example, if your Flash application contains links to pages inside your website, Google may now be better able to discover and crawl more of your website.

Q: What about non-textual content, such as images?
At present, we are only discovering and indexing textual content in Flash files. If your Flash files only include images, we will not recognize or index any text that may appear in those images. Similarly, we do not generate any anchor text for Flash buttons which target some URL, but which have no associated text.

Also note that we do not index FLV files, such as the videos that play on YouTube, because these files contain no text elements.

Q: How does Google "see" the contents of a Flash file?
We've developed an algorithm that explores Flash files in the same way that a person would, by clicking buttons, entering input, and so on. Our algorithm remembers all of the text that it encounters along the way, and that content is then available to be indexed. We can't tell you all of the proprietary details, but we can tell you that the algorithm's effectiveness was improved by utilizing Adobe's new Searchable SWF library.

Q: What do I need to do to get Google to index the text in my Flash files?
Basically, you don't need to do anything. The improvements that we have made do not require any special action on the part of web designers or webmasters. If you have Flash content on your website, we will automatically begin to index it, up to the limits of our current technical ability (see next question).

That said, you should be aware that Google is now able to see the text that appears to visitors of your website. If you prefer Google to ignore your less informative content, such as a "copyright" or "loading" message, consider replacing the text within an image, which will make it effectively invisible to us.

Q: What are the current technical limitations of Google's ability to index Flash?
There are three main limitations at present, and we are already working on resolving them:

1. Googlebot does not execute some types of JavaScript. So if your web page loads a Flash file via JavaScript, Google may not be aware of that Flash file, in which case it will not be indexed.
2. We currently do not attach content from external resources that are loaded by your Flash files. If your Flash file loads an HTML file, an XML file, another SWF file, etc., Google will separately index that resource, but it will not yet be considered to be part of the content in your Flash file.
3. While we are able to index Flash in almost all of the languages found on the web, currently there are difficulties with Flash content written in bidirectional languages. Until this is fixed, we will be unable to index Hebrew language or Arabic language content from Flash files.

We're already making progress on these issues, so stay tuned!
