  grigorios charam: Use mysql database and store keyword description of any page and title id and slug for any page. After this create link:
  
  
  And make redirect if article id exist redirect to slug url version for protect for duplicate content.
  
  For any page print the meta for mysql and for home page create a general meta tag!
  
  Any page or category for empty meta generate dynamic a link rel=canonical to link a home page...
  
  
  Any question???

  Richard Hearne: Hold on  ;- are you saying that you've been employed to do SEO work on this site?  ;Is it a client site or your own site?
• 
  Kapil Bhardwaj: Thanks  ;...
  
  And  ; Its not my site its client site..... ;
• 
  Richard Hearne: Does the client know that you have no idea what you're doing?
  
  I think you should seriously reconsider whether you are qualified to be providing these services.  ;I cant see any way you can deliver a quality service if you're knowledge of basics is so poor.

  Kapil Bhardwaj: Hahaha nice point..... Tell me one thing, suppose u have new seo work and client can't share website details or website access with you... So i think your  ;knowledge of basics is so poor.
• 
  Richard Hearne: >> client can't share website details or website access with you
  
  What type of client cant give you access to the target site?  ;It's probably not their site so.
  
  >> ;So i think your  ;knowledge of basics is so poor.
  
  It's not me asking the questions.  ;I have nothing to prove.
