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.
If your site already has a high domain authority (DA), you don’t have to worry about this step. If you don’t know what I’m talking about, domain authority is a search engine ranking score that ranges from 1 to 100, and it predicts how well the site will rank in result pages—it’s based on age, popularity, and size. Your brand-new blog will have a ranking around 1 (sorry), while Facebook has a ranking of 99. As you get bigger and better, your DA score will get higher.
Enhance your writing. So now people are hooked on the appearance of your blog, but now you’ve got to provide stellar content to keep them around. In general, blogs should be written with a light-hearted tone and easy to understand vocabulary (unless it’s an academic or otherwise specific blog). Get your blog optimized for search engines (SEO optimized) by using common search queries throughout your writing. This will move your blog closer to the top of search engine result pages, and make people more likely to read your posts.
I noticed you wrote that people could feel free to re-post the content with a mention or link. I recently had a large directory type website take a dozen or so pages of content from my website and put it on a dozen or so pages on their website (along with content from other businesses) with a mention of my business (but not a link back to the pages that the content came from).
That's a screenshot of the AdAge Power 150, a list that's been maintained for years in the marketing world and receives an endless amount of discussion by those listed (and not listed). For example, why is SEOmoz's Twitter score only a "13" when we have so many more followers, interactions and retweets than many of those with higher scores? Who knows. But I know it's good for AdAge. :-)
