Search Engine Optimization (SEO)
  SEO技术 - Factors Affecting Ranking in Search Engine
 
  • Age of site
  • Length of time domain has been registered
  • Age of content
  • Regularity with which new content is added
  • Age of link and reputation of linking site
  • Standard on-site factors
  • Negative scoring for on-site factors (for example, a dampening for sites with extensive keyword meta tags indicative of having being SEO-ed)
  • Uniqueness of content
  • Related terms used in content (the terms the search engine associates as being related to the main content of the page)
  • Google Pagerank (Only used in Google's algorithm)
  • External links, the anchor text in those external links and in the sites/pages containing those links
  • Citations and research sources (indicating the content is of research quality)
  • Stem-related terms in the search engine's database (finance/financing)
  • Incoming backlinks and anchor text of incoming backlinks
  • Negative scoring for some incoming backlinks (perhaps those coming from low value pages, reciprocated backlinks, etc.)
  • Rate of acquisition of backlinks: too many too fast could indicate "unnatural" link buying activity
  • Text surrounding outward links and incoming backlinks. A link following the words "Sponsored Links" could be ignored
  • Use of "rel=nofollow" to suggest that the search engine should ignore the link
  • Depth of document in site
  • Metrics collected from other sources, such as monitoring how frequently users hit the back button when SERPs send them to a particular page
  • Metrics collected from sources like the Google Toolbar, Google AdWords/Adsense programs, etc.
  • Metrics collected in data-sharing arrangements with third parties (like providers of statistical programs used to monitor site traffic)
  • Rate of removal of incoming links to the site
  • Use of sub-domains, use of keywords in sub-domains and volume of content on sub-domains? and negative scoring for such activity
  • Semantic connections of hosted documents
  • Rate of document addition or change
  • IP of hosting service and the number/quality of other sites hosted on that IP
  • Other affiliations of linking site with the linked site (do they share an IP? have a common postal address on the "contact us" page?)
  • Technical matters like use of 301 to redirect moved pages, showing a 404 server header rather than a 200 server header for pages that don't exist, proper use of robots.txt
  • Hosting uptime
  • Whether the site serves different content to different categories of users (cloaking)
  • Broken outgoing links not rectified promptly
  • Unsafe or illegal content
  • Quality of HTML coding, presence of coding errors
  • Actual click through rates observed by the search engines for listings displayed on their SERPs
  • Hand ranking by humans of the most frequently accessed SERPs
