  12. 12. London| 18–21 February 2013 | #SESLONUsing Xenu• If the site allows being crawled you can use Xenu to crawl it and then look at the information that comes out of it• Arrange it and behold …. @optimizeyourweb
  13. 13. London| 18–21 February 2013 | #SESLONUsing Copyscape• Copyscape was originally created to find “stolen” copy but works great when it comes to DC
  14. 14. London| 18–21 February 2013 | #SESLONContent ownership• Websites are often developed on a DEV url, which is in many cases open, but only used for collaboration between developers and site owners, then somebody uses Google mail to share it or it is sniffed by a subdomain finder. Then content ownership can be an issue… for a long time. @optimizeyourweb
  15. 15. London| 18–21 February 2013 | #SESLONImage Plagiarism• A search for ‚ritzy bryan‘ gives 895.000 results• When you click images... 5 of top 9 top are the photographers• But the top two are not on his website• Click on the image• Click ‚Image details‘ and you get lots of similar images• Scroll down and you get lots of plagiarizing websites

  17. 17. London| 18–21 February 2013 | #SESLONFrequent causes when starting a new site• Firstly make sure that your dev.server is under lock and key – Close it when you are done• If you are using something like a news or a product module over multiple sites, make sure that the ownership is clear• Not all of our content creates duplicate content on your site – Scrapers can give you hell! • Report plagiarism to Google as soon as you find it – take ownership. @optimizeyourweb
  18. 18. London| 18–21 February 2013 | #SESLON301, 404 – Default or not default and ….• 404s that are not 404s – Things can go a bit crazy if not inserted properly on large commerce sites as an example• WWW, Non-WWW & Default pages• Query strings and session IDs• Template content• Boilerplate repetition, publishing stubs & similar content• User generated duplicate (replica) content @optimizeyourweb
  19. 19. London| 18–21 February 2013 | #SESLONThe mother of all checklists ;-)• Take everything that is a likely cause and create a checklist and go through these items one by one and make sure they are in order• This is all common sense stuff and there is so much information online. You should not have to do the same mistakes as those before you….• Know your CMS before you start implementing it! @optimizeyourweb
