Imagine following thing:

My site works some specific keywords (keyword 1, keyword 2, keyword 3) as usual and inside it i have pages for each one of them:

www.mysite.com/keyword1.php ;
www.mysite.com/keyword2.php ;
www.mysite.com/keyword3.php ;

So, i want to get rank for my index with those 3 keywords. I can use the keyword anchors mentioned in each one of them linking to my index cause all of those pages are related - i´m mentioning those keywords in all pages. But if i do that i´ll lose the natural flow of information in the contents of my intern pages.

What i mean is … the anchor keyword1 in the page www.mysite.com/keyword2.php ; can link to my index instead of www.mysite.com/keyword1.php ; but this approach brake the flow of information. I opted to strengthen my index in this scheme instead of my internal pages.

I would like know what do you think about this approach?If is good forget those anchors for the internal pages or give power to my index through blog articles, link building with external pages and keep those anchors to each specific page.
