  Tessa Bonacci: I use word press and there are multiple pages the previous person intended to be "posts", but they did not do it correctly and added them as pages. The pages are spamy and offer no good content. Can i just delete these pages or will that cause broken links? ;

  SEMXE: +Tessa Bonacci ;you can do one thing.. create fresh quality content for all these pages (as they were supposed to be blog posts earlier).. make them live... and redirect your current pages to these posts.. tht way you won't have to face any broken links issue or won't lose any seo benifits of these pages.

  Tessa Bonacci: +SEMXE ;Correct, they were intended to be blog posts but were created as pages with urls that are extremely long and have about ten hyphens in them. I want to make sure I understand you correctly. When i create new blog posts, I should make these pages redirect to a blog post? What about the content that is currently on the pages?  ;

  Crea Content Marketing: Hi +Tessa Bonacci, ;
  Are these pages driving any traffic for you? And how many links do you have pointing to these pages? If there aren't many, and if you can change your own links that currently point to these pages to your new posts with actual content, getting rid of them completely (especially if they're spammy!) may be your best best. ;

  Tessa Bonacci: +Crea Content Marketing ;That is what i was thinking as well. We have no links pointing to the pages and I would like to get rid of them. They bring 0 traffic. They are basically just in the WP database with no links pointing to them but they are "published"

  Crea Content Marketing: +Tessa Bonacci ;here's some advice from SearchDiscovery:
  
  There are three main choices when it comes to addressing undesired URLs on a domain.
  
  1. Delete them and just let them fail (404 not found error)
  2. Redirect those pages (sure, but which ones?)
  3. Leave them alone (just do nothing – Undesired!)
  
  Some pages need to fail. They just do. Reviewing the advice from Wysz above, removing / deleting (not redirecting) low quality pages is sometimes the best choice.

  Hope that helps!

  SEMXE: +Tessa Bonacci ;as I read your comment above that these pages are driving 0 traffic and have 0 zero link value, then simply delete them... that will show 404 error.. but to overcome that issue.. block these urls from robots file and then submit a request to Google via GWT to remove these pages from their index.. tht way u won't face any issue.
