One of the coolest things about business blogging is the social interaction and community that is built when readers leave meaningful comments. Like a good story, a post elicits a response from the reader. As your community develops, the value of your brand increases. But this warm and fuzzy feeling that people get about your brand as they interact with you on your blog can be hard to measure and quantify. That’s where blog interaction metrics come in.

Building a blog to one or more interaction metrics can help you focus on what’s important - brand engagement.

Do you measure a successful post by the number of readers, bookmarks added to del.ic.ious, diggs, comments, number or quality of backlinks, or a combination of all the above? Some metrics have a place in your blog marketing scorecard, like number of comments. And some do not, like number of trackbacks (unless you like counting spammers — and that you could do all day!). Because the last thing you need is just more data for the sake of data.

Avinash Kaushik came up with some really nifty blog success metrics that really resonate with me. I bet they’ll resonate with you too. They are:

• Raw author contribution (posts per month and words per post)
• Audience growth (onsite & offsite, visitors and unique visitors)
• “Conversion” rate (comments per post)
• Citations (blog inlinks, Technorati rank)
• Ripple Index (# of unique blogs linking to your blog)
• Cost (time, hardware/software technology, opportunity cost
• Benefit / ROI (comparative vs. direct vs. “non-traditional” vs. unquantifiable)

As you start measuring the above and then gauging the success of what you’re doing on your blog based on these metrics, you can tie your activities back to something more meaningful than just the “hits” you’re generating.

If you want to learn more about metrics, I encourage you to watch the archived recording of a “Website Metrics and ROI” webinar that Avinash and I presented last year. No registration required. Just click and watch (or download). It’s 100 minutes of the two of us talking about our favorite metrics — not just for blogging, but also email marketing, web marketing, search marketing, and more. And if you just want to scan over our Powerpoint slides before you invest 100 minutes of your time (and I don’t blame you — time is precious!), here’s the PPT file. Enjoy!

What blog metrics do you value most? How do your readers interact with you? Do you have any particular reporting tools you recommend? Your interactivity is welcome and invited.

Not getting as much marketing power out of your blog as you’d hoped? The rules for successful blogging are the same whether you’re writing for personal or business reasons. First of all, you have to write about what you love or what you’re passionate about. When you write about what you are passionate about, readers will feel it too, and the entire process of writing will be more enjoyable as well. If you’re running out of topics or your blogging feels like a chore, then you should find a new angle on your work — one that you’re passionate about. Hopefully you love your work and your job, so it shouldn’t be too difficult to find things that are fun to write about, but sometimes it’s better that you concentrate on a specific aspect of your work that you’re particularly interested in.

If you have no passion for what you are writing about, why are you writing at all? Your entries will come across as boring or flat and you will not gain the readership your writing skills deserve. When you write about what you love, it is a lot easier to sound like an expert in your field. If you are not sure what you are passionate about, take the time to figure it out. You owe it to yourself, and your potential readers, to know and write about what makes you get out of bed in the morning. If your goal is to make money with a blog, write about what you love and the money (or sales) will follow… You will have more readers and will write better posts. Great content brings traffic/conversions and when you write about something you love it is difficult to write poorly.

What’s it like to read your favorite blogs? I’d have to say my all-time favorite blogger from a writing perspective is Fake Steve Jobs. Sure, he’s not even real, but he “keeps it real.” Every post is witty, and I love his creative use of language and his invented words (e.g. MicroTards, Freetards). The blog provides a little window into Steve Jobs’ psyche. Well okay, maybe not, since it’s actually being written by a Forbes magazine journo, but wouldn’t it be cool if it were the real Steve Jobs?

FSJ may not be the real Apple CEO, but Jonathan Schwartz definitely is the real CEO of Sun Microsystems, and his blog is an excellent example of great blogging. Jonathan posts about Sun projects that he finds exciting, and technology trends that he has an interest in. As a top-level industry insider, Jonathan makes you feel like you’re getting a unique perspective on information technology.

In the past I’ve held up science teacher Steve Spangler’s blog as an excellent example of business blogging, as well. Steve’s blog helps establish his expertise and showcase his brilliance, which keeps him busy in his various adventures. If you like science and haven’t visited Steve’s site yet, you’re missing out.
