Google modifie les règles d’utilisation du nofollow
En marge du salon search engine marketing expo SMX Matt cutts a mis en garde les webmasters sur les dangers de l’utlisation du no-follow.
Il en ressort que google veut absolument se réserver le droit d’utiliser le « nofollow ». Prosaiquement lorsqu’un webmaster utilisait le nofollow c’était pour redistribuer le potentiel de la page émetrice vers d’autres pages « destinataires » sauf celle vers laquelle le « nofollow » est appliqué.
On a donc appris la semaine dernière au SMX qu’une partie du potentiel que le webmaster souhaite économiser ou redistribué entre quelques sources sera perdu. Google cherche ainsi à décourager les jeunes webmaster qui utilisent abusivement le no-follow.
Un compte rendu de l’avis de Matt cutts:
So today at SMX Advanced, sculpting was being discussed, and then Matt Cutts dropped a bomb shell that it no longer works to help flow more PageRank to the unblocked pages. Again — and being really simplistic here — if you have $10 in authority to spend on those ten links, and you block 5 of them, the other 5 aren’t going to get $2 each. They’re still getting $1. It’s just that the other $5 you thought you were saving is now going to waste.
Further, it was explained that YouTube wasn’t doing sculpting way back in 2007 as a way to boost certain video content. Instead, it was that YouTube randomly shows some video content and didn’t want these random selections to perhaps gain more authority than they should. And even with the change announced today, that still works. In the past, the unblocked videos got more authority money and the blocked ones got none. Now, the unblocked videos still get authority money — just not as much — and the blocked ones still get none.
