Il semblerait que Google soit en train de mettre en place un programme spécifique à l'attention des webmasters. Il serait notamment prévu qu'un système automatisé prévienne les responsables de sites lorsqu'une tentative de spam a été détectée sur leurs pages afin de leur signaler leur mise en liste noire. Un mail de ce type serait envoyé aux webmasters :
From: Google Search Quality DO NOT REPLY
Date: 8 September 2005 23:10:04 BDT
To: [addresses removed]
Subject: Removal from Google's Index
Dear site owner or webmaster of [url removed],

In order to preserve the quality of our search engine, we have temporarily removed some webpages from our search results. Currently pages from [url removed] are scheduled to be removed for at least 30 days.
Specifically, we detected the following practices on your webpages:
On [url removed], we noticed that pages such as [url removed]/flight-to-sydney-australia.htm redirect to pages such as [url removed] using JavaScript redirects.
We would prefer to have your pages in Google's index. If you wish to be reincluded, please correct or remove all pages that are outside our quality guidelines. When you are ready, please submit a reinclusion request at [link]
You can select "I'm a webmaster inquiring about my website" and then "Why my site disappeared from the search results or dropped in ranking," click Continue, and then make sure to type "Reinclusion Request" in the Subject: line of the resulting form.
Sincerely,
Google Search Quality Team
Ce programme, en phase pilote, sera-t-il étendu ? Disponible en d'autres langues et pour d'autres pays ? Est-ce un signe annonciateur d'une vaste campagne de lutte de Google contre le spam ? Le projet a été confirmé par Google, Matt Cutts, porte-parole technique du moteur, indiquant qu'une première "salve" d'avertissement portait sur les liens JavaScript, mais que le texte caché était également "dans le collimateur"...
