Blogging Quantities

Okay...got a few niche sites up and traffic is coming from seo and some submitted articles to ezinearticles. I've been posting comments on blogs but I'm not sure at what scale I should be doing this. Anyone care to comment???

I know this is VERY arbitrary...but per week...what type of average marketing efforts should I be seeking?

Number of blogs to leave comments on per day? per week?
Number of articles to submit per week? per month?

Advice?

I would say that it's more important to blog consistently and do guest blogging before commenting on blogs. It also depends on your niche but that's what I recommend. And I would do the guest blogging over submitting articles.

I'm not sure about anyone else but I don't use articles from directories on my sites/blogs anymore.

Just some quick thoughts.
