We have multiple products and our domain name is separate for each of these products. We have limited resources to manage the blogs. Is it best to maintain one blog for all the products or is it better to keep start by keeping them separate
One blog. Period.<p>The success of a blog is directly related to the quality of the content and the posting frequency. Best practice is to have a posting frequency of no less than once a week but more frequent is better.<p>If you can only manage the once a week scheduled, ensure that the posts occur on a predictable update schedule (such as every Monday morning). After your third post begin submitting the blog to every search engine crawler and RSS aggregator (RPC services) you can possibly find to raise search visibility.<p>Also make sure to have your blog generate sitemaps. Create webmaster services accounts with Google, Bing, Yahoo, etc... and be sure to add your site and the link to your XML sitemaps where relevant.<p>Lastly, once you have been active for a few months, carefully review your analytics and begin tuning your blog to respond to traffic (eg, is a certain kind of product getting better traction? Adjust your product line accordingly if reasonable).<p>I could go on, but this will kick you in the right direction.
