newbie questions about blog posting

hi few questions about blog posting just so I know I am doing it right or wrong. Let's say I find an auto approve blog where I can comment, then:

1. I put 1 comment on the article or also possible more than 1 to cater for different keywords that I have?

2. I put this comment with my root URL as link or I must link to specific articles? or mix?

3. Do I also post comments on other posts of that same AA blog? lets say do I do 1 keyword per post? or I do max few comments on different posts and that's it?

Anything else please add

Thank you for your advice!!!

Q1. I put 1 comment on the article or also possible more than 1 to cater for different keywords that I have?
If you have only one domain then you should comment only once on each comment page.. You can comment on same page for different domains..


Q2. I put this comment with my root URL as link or I must link to specific articles? or mix?

choose the url according to the keyword.. if you want to promote root url then comment using root page url and its corresponding keywords.. if you want to promote some article then put url of article along with keyword of article..

Q3. Do I also post comments on other posts of that same AA blog? lets say do I do 1 keyword per post? or I do max few comments on different posts and that's it?

You can post comments on other posts of the same AA blog.. But limit it to 5-6 only because if you will write comments on all posts of same blog then it will treat your site as spam and hence may remove all of your comments,,,

if still have some confusion then you can pm me..

In general, 1 comment with 1 link to a domain per article is enough. I only would write 2 or more comments or include 2 links to the same domain, if it would be a PR6 or higher and d0-follow. But that's just me.
But of couse you can use the same AA blog more then one time. Everytime you created a new blog/site, you can return there and add your link.

Always create backlinks to all of your pages and not only to your root domain. You want not only rank with your root domain but with your pages also.

And yeah it's also not a bad idea to comment on the other pages of the AA blog too. The more links the better, especially when we're talking about low quality blog comments.
