Posterous is known as the most “social” networking place of social media. It’s also the ideal solution for sharing content that’s too long for a tweet and too short for a blog post.

There are many different reasons and motivations to create a free Posterous account. Let’s have a look at the 7 most common reasons for businesses to use Posterous.

#1: Can Replace Your Blog

When a regular blog is not for you, Posterous can give you similar advantages to a regular blog without the work of setting up a blog and maintaining it.  All you have to do is send in your content by email.  It’s that simple.  This is why Posterous is great for lifestreaming.

This can be a good starting point for businesses hesitating to create their own blog. Posterous can provide a place to learn more about social media and develop the right content strategies.

#2: Fills a Gap Between Blogging and Microblogging

Posterous is an easy way to publish more content to reach different audiences. Steve Rubel says, “I still see a big space in between blogs and Twitter that allows you to have a hub and spoke strategy and post in multiple formats.”

And as Ted Villa says, “Posterous is clean and nimble, simple to use and a great tool in any organization’s social media toolkit. It’s a great way to extend a client’s footprint online and increase links to their site as well as their social media sites.”

This can fill a gap in your presence on social media.

#3: Can Improve Your Visibility

Posterous can help you improve your visibility in search results in two ways.

First, you have more updates for search engines to find. If you like to share photos and videos online, Posterous makes it very easy to do this (see reason #7 below for more details). And with photo and video publishing made this easy, you end up sharing more content to increase your online search results.

Second, you can publish your Posterous content on your own website. Unlike other social media platforms, you can set up your Posterous account on your own URL.  This means you can set up your Posterous account on:

• Your own domain name separate from your company website
• Or even use a sub-domain of your current website or blog

This is something important to keep in mind as the social media landscape changes over time.

#4: Gives You Another Voice on Social Media

Many business professionals also use Posterous to post content that would be off topic on their main website or blog and engage with a different audience online.

Posterous provides an easy venue to share different “social” content. A separate platform makes it easy to create an additional point of connection with your audience, with a different style, to engage different mindsets.  As Debbie Weil says, “There are distinct differences in how you talk or write for the different platforms.  Simply put, you write in a different ‘voice’ and, generally, talk about different topics.”

This makes it easy to reach out to different audiences.

#5: Makes it Easy for Groups to Publish Content

Posterous allows you to set up group accounts too.  This means you can set up:

• Posterous pages for individual team members
• Collaborative Posterous pages for different company employees to post on the same page
• Collaborative Posterous pages to bring people outside your company to collaborate on one Posterous page

#6: Helps You to Segment Content for Different Audiences

You can use your Posterous account to create different points of contact with your audience.  Pat Kitano says, “I originally intended this slideshow (How to create a blog without “writing” one) for local businesspeople who wanted a blog for marketing purposes, but didn’t have the inclination to start a blog due to writing and time commitments. After posting the slideshow, I received feedback that Posterous was a great method to create new ‘blogs’ on a variety of topics and interests that were parallel to the principal blog. One mentioned how fast Posterous blogs were indexed by Google.”

This makes it easy to test different market segments outside of your main blog or website.

#7: Is the Easiest Option to Share Photos

Posterous is simply the easiest social media platform to share photos and videos.  All you have to do is email your photo or video to Posterous and it does everything else. This means you can publish your favorite photos and videos from any location where you have access to your email, even from your mobile phone.

This is why many users choose to post all of their photos and videos to Posterous and set it up to feed their Facebook, Twitter and other social media profiles.

Bonus: Makes You Easy To Connect With

Sometimes a personal touch helps you to create a stronger connection with your audience on social media.  This is why some business professionals use Posterous as a place to provide a unique glimpse into their personal lives.

A Step Toward Creating Social Connections

Creating a social presence and adapting to different social media platforms are not easy for many businesses.  Posterous provides a way for businesses to make a social connection between their own website and other social media platforms as they learn more about incorporating social media into their current marketing tactics.
