Google Algorithm

  As SEO expert I decided to challenge myself and try to explain Google Algorithm formula. My work based on my observations, research, and reading.

 Domain:

• Domain age - WHOIS database
• Domain history - past and present owners. Bad history could affect current owners.
• Domain name - related keywords in domain could improve rankings.
• Domain usage
• Brand name
• gTLD
• Where registered (Geographic location) - helps to rank in local search.

 Inbound Linking:

• Link age - older link better.
• Related website
• Website quality (TrustRank, Domain power).
• Deep links
• Page straight - SEOmoz provide some type of tool which might help you find Page straight.
• Quantity - not important for low quality links.
• Type of a website (blog, directory, forum, social network, static, dynamic…)
• Anchor text
• Surrounding text (text around link) - thats why content links is important.
• Link Position (content, footer, header, sidebar etc) - link inside content is the most powerfull.
• One way
• Reciprocal - loosing power.
• Page type (partners, news, clients, archive, resources etc)
• Amount of other inbound links on the page.
• Pagerank (loosing value)
•  gTLD - .gov, .edu, .mil rank better

Keywords:

• Domain, folder, url
• Header 
• Meta title - keep under 150 chars
• Meta keywords - keep under 500 chars
• Meta description - keep under 200 chars
• Tags
• Position in content
• Page title
• Anchor text - links which point to web page.

Content:

• Duplication - often can meet in php
• Grammar mistakes
• Academic language
• Quotations
• Paragraphs
• MLS writing style
• Tags and title
• Location on the page - keywords in the header and body rank better.
• Amount of content pages
• Amount of unique words, letters
• Content changes (old pages without changes rank worse)
• Privacy page - Google doesn’t trust websites without privacy page.
