De curand au fost niste "scurgeri" referitoare la modul in care Google clasifica si identifica web spamul.
* Long domain names
* .info, .cc, .us and other cheap, easy to grab TLDs
* Short registration period (1 year, maybe 2)
* High ratio of ad blocks to content
* Javascript redirects from initial landing pages
* Use of common, high-commercial value spam keywords like "mortgage," "poker," "texas hold 'em," "porn," "student credit cards," and related terms
* Many links to other low quality, spam sites
* Few links to high quality, trusted sites
* High keyword frequencies and keyword densities
* Small amounts of unique content
* Very few direct visits
* Very few links sent out in (non-spam) email to the site
* Registered to people/entities not associated with trusted sites
* Not frequently registered with services like Yahoo! Site Explorer, Google Webmaster Central or Live Webmaster Tools
* Rarely have short, high value domain names
* Often contain many keyword-stuffed subdomains
* More likely to have longer domain names
* More likely to contain multiple hyphens in the domain name
* Less likely to have links from trusted sources
* Less likely to have SSL Security certificates
* Less likely to be in directories like DMOZ, Yahoo!, Librarian's Internet Index, etc.
* Unlikely to have any significant quantity of branded searches
* Unlikely to be bookmarked in services like My Yahoo!, Del.icio.us, Faves.com, etc.
* Unilkely to get featured in social voting sites like Digg, Reddit, Yahoo! Buzz, StumbleUpon, etc.
* Unlikely to have channels on YouTube, communities on Facebook or links from Wikipedia
* Unlikely to be mentioned on major news sites (either with or without link attribution)
* Unlikely to register with Google/Yahoo!/MSN Local Services
* Unlikely to have a legitimate physical address/phone number on the website
* Likely to have the domain associated with emails on blacklists
* Often contain a large number of snippets of "duplicate" content found elsewhere on the web
* Unlikely to contain unique content in the form of PDFs, PPTs, XLSs, DOCs, etc.
* Frequently feature commercially focused content
* Many levels of links away from highly trusted websites
* Rarely contain privacy policy and copyright notice pages
* Rarely listed in Better Business Bureau's Online Directory
* Rarely contains high grade level text content (as measured by metrics like Fleisch-Kincaid Reading Level)
* Rarely have small snippets of text quoted on other websites and pages
* Cloaking based on user-agent or IP address is common
* Rarely contain paid analytics tracking software
* Rarely have online or offline marketing campaigns
* Rarely have affilliate link programs pointing to them
* Less likely to have .com or .org extensions
* Almost never have .mil, .edu or .gov extensions
* Rarely have links from domains with .edu or .gov extensions
* Almost never have links from domains with .mil extensions
* Rarely receive high quantities of monthly visits
* Rarely have visits lasting longer than 30 seconds
* Rarely have visitors bookmarking their domains in the browser
* Unlikely to buy significant quantities of PPC ad traffic
* Rarely have banner ad media buys
* Likely to have links to a significant portion of the sites and pages that link to them
* Extremely unlikely to be mentioned or linked-to in scientific research papers
* Unlikely to use expensive web technologies (Microsoft Server & Coding Products that Require a Licensing Fee)
* Likely to be registered by parties who own a very large number of domains
* Unlikely to attract significant return traffic
* More likely to contain malware, viruses or spyware (or any automated downloads)

Documentul respectiv am avut ocazia sa il vad mai demult, vad ca abia acum se discuta despre el....
Discutam despre criteriile aste? Au valabilitate si pe .ro?
