what is google bowling?

[Jaygour]

Google Bowling means Manipulating the external ranking factors that Google uses to penalize a site against your competitors (or someone you just don’t like or want to appear in the SERPs).
There is one thing that protects a website against Google Bowling - a solid back link profile of its own. The more your "real" quality backlinks grow, the less anyone Else's malicious actions can affect it.

Thanks for share such information.
