Google relevancy algorithm explanation


Here under a very very very quick explanation of Google relevancy algorithm. It is based on the calculation of Google adwords quality score but the more time goes the more those too are close.

Relevancy = (KW Usage Score * 0.3) + (Domain Strength * 0.25) + (Inbound Link Score * 0.25) + (UserData * 0.1) +(Content Quality Score * 0.1) + (Manual Boosts)- (Automated& Manual Penalties)
