  Katrina Joy Plam: Question RE: Duplicate Content ;
  
  I have a client creating a a 7-part blog series. In each installment, there's an identical into and outro paragraph which explains the series and is important to the user. ;
  
  Any suggestions to avoid the duplicate content issue across this blog series?
  
  Thank you in advance!!! ;

  Jason Squardo: If you are able to work within the page code you have a few options. ; One simple solution is to include the text in an image instead of text. ; You can also use JavaScript to include the text to the page which will essentially make it invisible to engines.
  
   ;It sounds like each part will be pretty lengthy, assuming all the other content is unique you probably don't have much to worry about from a duplication standpoint.

  Mikita Shah: +Jason Squardo hey Jason you have a good suggession but don't you think that by making content invisible for engines would create a problem in indexing the pages.

  Ranu Jain: Hi Katrina,
  
  Google has cleared that duplicate content issues are rarely a penalty. ;Duplicate Content won’t hurt your site, unless it is Spammy. ;
  
  This is what  ;Matt Cutts said twice that you should not stress about it, in the worse non-spammy case, Google may just ignore the duplicate content. ;

  Jason Squardo: +Mikita Shah it would depend how you executed it. ; You would only want that specific set of content to utilize the JavaScript to display. ; This would not affect the indexing of the rest of the page.
