I'm trying to figure out how to get a tumblr blog to run under a subdirecory (not subdomain) and I'm kind of stuck. I was thinking of changing the cname of my domain to tumblr blog but that would change the entire domain, correct?Would it be done somewhere in the .htacess?I've seen it in action here http://www.senanyc.com/blog/ but I have no idea how they did it .
Installing tumblr on a subdirectory
301 redirect;tumblr
I haven't tried it myself, but this guy offers a solution: http://web.archive.org/web/20070702115331/http://henrik.nyh.se/2007/06/tumblr-in-a-subdirectory. You need access to to your htaccess file and you need to be able to save a php script. It looks fairly straightforward. You can draw further inspiration (at least for the redirecting part) from this guide on how to install Wordpress in a subdirectory:http://codex.wordpress.org/Giving_WordPress_Its_Own_DirectoryAnd finally, on SO the question has been asked, it is basically the same method (changing your htaccess file: https://stackoverflow.com/questions/10034152/htaccess-how-to-redirect-subdirectory-to-external-urlAs for SEO benefits of using a sub-directory, this guy here states that using a sub-directory is best from an SEO standpoint. http://www.agent-seo.com/blogging/seo-subdomain-vs-subdirectory/. This one here seems to agree: http://www.timpeter.com/blog/2011/12/14/subdomains-vs-subdirectories-and-seo/.I don't know how that applies to your situation where the blog is hosted on a different IP address - Tumblr is elsewhere, after all. I don't think there is a big impact though - I have found no evidence to support it. I would only ask myself that question if you are trying to rank for highly competitive keywords. But then you would be probably better closing your Tumblr blog and moving the posts to a subdirectory on your site. But again, this is only important if you are competing with lots of other sites where every bit of SEO benefit counts.
