What are your opinions on time that should be alloted for adding products to a commerce site vs. building links through blogs, directories, articles, social media, etc.
building links is priority, but don't neglect your content either. just think - there is no point in having lots of content if nobody sees it, and there's no point in having lots of visitors if you have little content.
I agree with Matt5409... Until you are about 75% satisfied with your back links, I would spend almost half my time working on that. If they are both important then, they both need to be taken care of. 50/50 I say!
