Cross posting is all about spreading the reach of your blog content with minimal effort – you just publish an entry on your main blog and it gets mirrored across all your other blogs.

Here are some scenarios where you may consider cross-posting your blog articles:

Why Cross-Post your Blog Entries?

1. You have just one blog but are looking for a system that will backup all your blog posts automatically.

2. You maintain two blogs – one is private (or password protected) for family members while the other one is open for all. You can use cross posting to publish blog posts that may be of interest to either groups.

3. You have some old blogs on Live Journal or TypePad that are now lying in an abandoned state but there are some people who are still subscribed to those blogs. Cross posting (with short summaries) will help you grab the attention of your old audience to your latest content without any effort.

4. You are into some sort of "reputation management" business and have therefore created blogs across every blogging, μ-blogging or social networking platform including Tumblr, Twitter, Facebook, Bebo, Xanga, MySpace, Diigo and so on. You can thus spread word about your client’s new product more easily by posting the same message to multiple sites simultaneously.

How to Set-up Cross-posting?

Now that you know the benefits of cross posting the same blog content to multiple sites, here’s how you can do it with Windows Live Writer.

The first step is to install the xPollinate plugin from Windows Live Gallery. Now add all your secondary blogs to Windows Live Writer – this is a mandatory step because this plugin uses the Live Writer database to figure out addresses of your other blogs.

Now publish some article to your main blog and click the xPollinate button. Here you have the option to pick individual sites / blogs that should mirror your original blog post. You may choose excerpts instead of republishing the full article on secondary blogs and these cross-posts can also link to the source article – all in a simple click.

And since the plugin can be integrated with Ping.fm API key, you may use Windows Live Writer to update your current status on Facebook, LinkedIn and other social sites.
