what you want do have link from home page to your new post that will transfer some page rank forget exact percentage that transfer.link from post back to homepage that way your homepage send pagerank to blogpost then blogpost send pagerank back to homepage improves pagerank of homepage which will then build pagerank of post. this recurring cycle i hope i explain it well enough
Thats not correct. Its better to have a link from the homepage to the post only, then a ton of backlinks to the post directly (mix it up, so PR0-PR9, not just high ones).
When google follows a link and then on that page finds a link back, it discounts or reduces the importance of that link. Also remember links from the same domains and IP's (servers whether or not your own site) also carry much less weight with Google.
This is why linkwheels are so effective, but as a simple example lets say there are only 5 sites. One is your 'money-site' (your actual site) which sits in the middle and the other 4 (A,B,C,D) are mini-onepage-sites based on the same niche sat as a square around it (ok so not looking like a 'wheel' but you get the idea).
All of the sites are hosted on different domains with different servers (IP's). All four sites link directly to your money-site, but this doesnt link back to any. Then site A links to site B, which links to site C, which links to site D, which links back to site A. This way you pump all the PR juice around each site but dont lose anything for reciprocal linking.
Of course it needs to be much bigger than this and these days far more complex as Google try to detect them. Such as also linking C to A and D to B, then linking a random number (1-5) to external independent sites from each one, as well as interlinking money-sites themselves and the different spokes (A-D) of multiple linkwheels (even if its in a different niche). Also use different sets of backlinks to the spokes of the wheel, rather than the same ones on all (dont use links from the same sites for every one).
Sorry wrote a bit more than expected as its off-topic.
But the idea if you only want PR juice is to link your homepage to your post, but dont link back. However, as a general design practice if you want the same people revisiting your blog, then they will want to be able to explore it and you would put a link back so they can see other posts.
