It is important for a firm to reach out to consumers and create a two-way communication model, as digital marketing allows consumers to give back feed back to the firm on a community based site or straight directly to the firm via email. Firms should seek this long term communication relationship by using multiple forms of channels and using promotional strategies related to their target consumer as well as word-of mouth marketing.
Numerous niches in the blogosphere have a few "big sites" where key issues arise, get discussed and spawn conversations on other blogs and sites. Getting into the fray can be a great way to present your point-of-view, earn attention from those interested in the discussion and potentially get links and traffic from the industry leaders as part of the process.
Once you've determined the communities where your soon-to-be-readers gather, you can start participating. Create an account, read what others have written and don't jump in the conversation until you've got a good feel for what's appropriate and what's not. I've written a post here about rules for comment marketing, and all of them apply. Be a good web citizen and you'll be rewarded with traffic, trust and fans. Link-drop, spam or troll and you'll get a quick boot, or worse, a reputation as a blogger no one wants to associate with.
I have noticed that we get some incredible traffic for series of blog posts and the posts which answer really specific questions. I know this wasn't about content planning but honesty believe that making a schedule and focusing in on a topic of the month is a great way to break budding bloggers into the habit of posting regularly with focussed material.
