Link footprints

[asystematic]

Hi! I have question about link footprints. What should be taken into consideration? Is it real issue when your backlinks have heavy footprint? Thanks for answer..

Here are a few footprints which Google can use when evaluating your links (some are algorithmic and some manual if you are under audit/review and some are cross-referenced):

• Time of the link placement and any related groups of links generated within the same timeframe
• Link location (blog roll, footer vs content and navigation)
• Pattern of buying from known link sellers
• Strict use of exact match commercial terms in anchor text
• IP address / C-class
• Author name in article submission
• Open calls and invitations for link exchanges, selling, buying
• Widget anchor text manipulation

Or anything else that can be seen as a link scheme.
