We are seeing some success with clients using our EDU pages to build up multiple results in Google. The indented link you see below some search results is for multiple pages that are both relevant. Webmasters desire this additional link to make your page stand out in the results.
We have advised some clients to link to some optimized internal pages. We like to see clients mix up their campaign with some links to homepage, and some to internal pages that are optimized for that particular keyword. We are seeing some results with multiple listings, and indented results.
What we did for a client already ranking #1 in Google:
We recently worked with a high profile client who had done extensive SEO work. They were already #1 for their keyword, so we linked that keyword to 2 different internal pages that were optimized for that word. This was a 15 page package, with 2 links per page, the same 2 links on each page, to these internal pages. The results: #1, #2, and #4 spot in Google.
