What is the Proper Use of 301 redirects for SEO purposes?

I heard and read from different sources that 301 redirects from aged domains with healthy link profiles is great to boost a sites rank as oppose to building a site around the page and linking it to the domain you want to rank. Whats is the best practice for this strategy?

Thanks

Take every 301 redirect you can get.  There may be link equity which is unitilsed there.

Well a 301 redirect is a permanent redirect so it passes on 90-99% of link juice gained by the page your are redirecting. Therefore it would be better to 301 redirect an old page domain with a healthy link profile as you will pick up benefit from the multiple links gained as opposed to one link from a site of reasonable authority if you were to build a site around that page. The ranking impact from the redirect will be far greater as you are essentially gaining multiple links in one hit once the search engines catch up and recognize the redirects, thus having the greatest impact on ranking in relation to the two methods you mention above. Hope this makes sense...
