What Makes A Page Spam?

What makes a page spam?:

• Hidden text or links – may be exposed by selecting all page text and scrolling to the bottom (all text is highlighted), disabling CSS/Javascript, or viewing source code
• Sneaky redirects – redirecting through several URLs, rotating destination domains cloaking with JavaScript redirects and 100% frame
• Keyword stuffing – no percentage or keyword density given; this is up to the rater
• PPC ads that only serve to make money, not help users
• Copied/scraped content and PPC ads
• Feeds with PPC ads
• Doorway pages – multiple landing pages that all direct user to the same destination
• Templates and other computer-generated pages mass-produced, marked by copied content and/or slight keyword variations
• Copied message boards with no other page content
• Fake search pages with PPC ads
• Fake blogs with PPC ads, identified by copied/scraped or nonsensical spun content
• Thin affiliate sites that only exist to make money, identified by checkout on a different domain, image properties showing origination at another URL, lack of original content, different WhoIs registrants of the two domains in question
• Pure PPC pages with little to no content
• Parked domains
