Hello Mathew and Mark congrats for the great support and highlights.
In the light of what you are explaning here could you please supoport me in this question concerning Canonical or 301 redirect? My issue is in terms of SEO when doing canolical.
I have a page with a long post title and url path name (more than 70 caracters and 115). This page has many visits but I am changing the SEO website structure according to SEOMOz and forums guidelines for the length names so: I WILL CREATE A DUPLICATE PAGE WITH THE SAME INFO.
This issue has been marked as an issue in the SEO tools, for long names>70 and url path names>115
My question is which option should I use and you would recommend me?
1. OPTION 1: Ideally I would like to keep the old post, so I should use the canonical tag, but my main concern is if the search engines in terms of SEO, even the canonical has been done, will penalise my SEO as there is still a post with bad SEO optimising, or if this is not the case because I already used the canonical. The duplicate content would still exist!
2. OPTION 2: Eliminate the post and redirection 301 to the new page to keep the juice.
I would prefer option 1, as I keep both post and page, but only if searchengines do not penalise my SEO as they detect a long post name and url path name.
Thank you very much for the help,
Antonio
