I've been digging around looking at sites who have a lot of hits to see how they are doing things.
I noticed on Tumblr, a few big sites posting to their Tumblr page using shortened URLs for posts that link directly to their main site. There seems to be no easy way to do this, so I assume they are copy/pasting URL into a shortener tool like bit.ly and then posting on Tumblr.
My question is why would they do this? Does it hurt your SEO to post full site URLs on Tumblr posts which link to all…
