Indexing and Backlinking Question

Hello,

When you first create a new site in a micro niche do you finish publishing all articles before you start thinking about indexing as a batch or do you publish one, start to get that indexed and then move onto the next article?

Also in regards to building back links, if you have a site that is targetting one main keyword but each post targets a micro niche inside that particular niche, where do you send your backlinks?

It will be easier to explain with an example, say you have the niche:

'improve tennis swing' and the URL is improvetennisswing.com, then you create a post about 'how to improve my forehand' so you structure the URL 'improvetennisswing.com/groundstrokes/how-to-improve-my-forehand' - do you then send your links directly to the post or just straight back to the homepage? I have asked another warrior and he just sent directly to the homepage but I was wondering what everyone else did with this.

I personally was thinking that I would send the majority back to the homepage but if I am commenting on blogs I would link directly back to the post?

Can anyone outline their strategy for the above two questions.

Thanks in advance!
