SEO impact of redirecting domain to subpage on other site?

I noticed a well known IM product guru has a set up where each product (this person has many products) has a dedicated domain name, but the domain reroutes to a subfolder on this person's blog. So several different product-based domains all send the user to different folders of the same authority blog. These blog pages are where the squeeze/sales pages are contained.

I would like to know more about this strategy. What are the pros and cons of doing this? Does this give more link juice to the page on the blog? Does it give more link juice to the blog?

That's part of a greater question I have. Here it is:

• Let's say I have a domain mydomain.com. And it redirects to yoursite.com.
• (Does that mean that the page mydomain.com/index.php gets redirected?)
• Now, if I put out there 100 backlinks to mydomain.com/(index?), does Google see that as 100 links for mydomain.com/, or 100 links to othersite.com/page?
• Does google reward the first or the second site as getting 100 backlinks?
• One scenario might be that I create a bit.ly/123 link to my site, put that in an article, and get that article to show 100 times on the internet. From a perspective of SEO (rather than organic traffic), does having 100 copies of the bit.ly link out there help me?

In the case I mentioned at the beginning of this post,

• where site.com/ redirects to othersite.com/folder/page, and Google gets redirected to the second page from the first , does it associate everything it sees on the page it lands on with the first URL or the second URL?

Do links to a blog post count (for SEO), as links to the main blog URL itself (because if SEO treats each page as separate then the answer should be no)? Do lost of backlinks to a domain name help out the serp position of the sub pages (again ...)?


And, for all this, does the type of redirect matter? I know there are several flavors but I can never keep them straight.

Curious because I was wondering if I host sales pages as subpages of my blog, instead of on their own domains, will that benefit my blog?
