Il est maintenant possible d'extraire ces informations en format texte pour les inclures sur votre site pour que l'information qui est contenu dans le vidéo soit finalement déchivrable par les moteurs de recherche. Voici comment procéder :
- Vous trouver un vidéo avec des sous-titres (closed captionning) comme celui de mon guru préféré Matt Cutts :
- Vous allez ensuite sur l'URL suivant chez Google Vidéo qui va extraire le fichier xml du sous-titrage en replaçant le numéro d'identité du vidéo (en italique ici) :
- Vous copier le code généré avec les étiquettes XML et vous aller ensuite sur cet outil de NiceTutor (http://www.nicertutor.com/xml.cgi) pour enlever les étiquettes et ne conserver que le texte. Et voilà !!!
Exemple du vidéo de Matt Cutts :
Today's question comes from Brian, in Seattle, Washington. Brian asks, Many are talking about losses of traffic with long-tail searches." And he points to a webmasterworld url. "I was wondering if you could give us an update on what is happening with Google right now?
Caffeine update? Algorithm change? Temporary?"
Ok, fantastic question! A lot of webmasters have been talking about it, so I'm glad I have a chance to address it. Uh, this is something that webmasterworld called "Mayday", and it
sort of happened April 28 through May 3rdish, so right around the first of May, so that's
why they've been calling it Mayday. Um, it is an algorithmic change, and it does affect
long-tailed searches more than head searches. Uh, it is deliberate, and it's a quality change that's been through all the normal quality launch committee, side-by-sides, making sure that things look good from a quality perspective. So, it has nothing to do with Caffeine, although Caffeine is proceeding apace, so it's completely independent or orthogonal of Caffeine. It is an algorithm change and so there's no manual stuff involved here, this is purely our algorithms thinking that some sites are a better match for some queries than some other sites. Uh, and it's not temporary. This is something where we're trying to assess the quality of sites, we're trying to find the best sites that match up to long-tailed queries, and it's an algorithmic change that changes how we assess which sites are the best match for long-tailed queries. So uh if you're affected by Mayday, the sort
of thing to think about is, you know, go back, ask yourself: Have I got the highest-quality
Am I showing up for the most relevant searches?
What sort of thing can I do in terms of adding great content, making sure that you know, people consider me an authority, that I'm not just matching something that's off-topic, or that users won't find all that useful?
But the main thing to know is, it is an algorithmic change, it's gone through the full process. Uh, we don't expect this to be temporary, there was no sort of human judgment involved with, "We thought this site was good, or we thought it was bad" instead it is algorithmic. It does affect long-tailed searches more, and after going through the entire evaluation, we did decide that it was a quality win, uh and so a few people have noticed it, but not the entire world has noticed it. Bear in mind that we make over four hundred
changes per year, in terms of actual quality changes where we're tweaking, or introducing, or improving an algorithm. So, this is one of those changes. It was a little more visible to, uh, some people who really pay attention to long-tailed searches, but we do believe it's a quality win, and we do expect it to continue going forwad.
