A Little Piece of the Google Algorithm - Revealed
GoogScore = (KW Usage Score * 0.3) + (Domain Strength * 0.25) + (Inbound Link Score * 0.25) + (User Data * 0.1) + (Content Quality Score * 0.1) + (Manual Boosts) - (Automated & Manual Penalties)
Where
Inbound Link Score
- Age of links
- Quality of domains sending links
- Quality of pages sending links
- Anchor text of links
- Link quantity/weight metric (Pagerank or a variation)
- Subject matter of linking pages/sites
Inbound Link Score * 0.25.
Any better formula or only pure guessing around own sites? Come on WPW members, beat this forumla.
