Dangerous! Make Auto Post to Another Blog with Posterous

Are you looking for a short way to make auto post from your blogs to another social media like Facebook, Twitter, LinkedIn, Google Buzz, or even Plurk?

Well, Posterous give you all simplicity with their single account. It is true that super simple to post your content to your blog and post to any or all of the following:

Facebook (Profiles and Pages), Twitter, LinkedIn, Google Buzz, FriendFeed, Jaiku, Plurk, Identica, Blogger, Tumblr, Livejournal, Shopify, Typepad, Xanga, WordPress (XML-RPC must be enabled), MoveableType, Drupal, Flickr, Picasa, YouTube, Vimeo, Viddler, Blip.tv, Scribd, and Delicious.

But what they are not saying is that if you use Posterous to post to another blog, and you want the other blog to be the official source of of the information in Google search results, you will run into problems. Google has made changes to their search indexing algorithm, called "the Panda Update." They are penalizing sites that post information that is duplicated elsewhere, and are favoring (rightfully so) the original content.

A made up but realistic use case.

To get an idea about how this could effect a Posterous user, let’s create an imaginary use case. Joe Blogger has a Blogger blog with a custom url pointing to his blogspot blog. He uses Posterous to email his post to Posterous, and auto posts to his main blog, facebook page and send a tweet about it. Very cool. Or is it?

There are two problems with this.

First - Google will naturally see that Posterous, not joeblogger.com is the originating website for the content, thereby indexing the main sight lower, if at all.

The second problem is this - the facebook post and the tweet are going to point the reader back to Posterous, not Joe Blogger's intended sight, and this hurts Joe's main sight rankings even more. Search engines are now taking social networks and the amount of sharing into account when they rank content.

So, what to do moving forward?

The last couple of years of claims that Posterous is the super simple way to post everywhere may be true, but it isn't really the best way, AND it was never really the intention of the company for it's users to operate this way.

I have pretty much done what he suggests, that is make Posterous my main and pretty much only platform. If I had a lot of link love built up on another platform however, I'd be hard pressed to make the switch, the platform is just to limiting for many people.

That's why it can be dangerous way if you want to make auto post to another blog with Posterous. So, what do you think?
