Welcome to the Q&A Forum

I agree with Ray. However, I tried to crawl both your old url & new one always got a "Connection refused" error in Screaming Frog (even when reducing crawlspeed & increasing default response timeout). . Maybe this is completely unrelated, however never had this on other sites before. Did you try to fetch the new pages in Webmastertools? Your robots.txt is quite long - you're sure that all pages that need to be indexed can be indexed? (completely unrelated to the indexing problems - I used webpagetest.org to see if your site was accessible by other automated tools - it worked, but also revealed that your pages are extremely heavy to load) Dirk

If you want Google to recognize items in your portfolio as separate pages then you should really create HTML snapshots. You can find pretty much every thing you need to know about the process here  https://developers.google.com/webmasters/ajax-crawling/

To clarify, I agree with Joe's response as well. On your home page, like your facebook page. On the remaining pages of your site, tie the like function to the page. Some sites break their like buttons down further. You can have a product page which shows multiple products where you place a Like button next to each product. Another example would be this Q&A section. You can place a Like button next to each reply and Like them individually. The system offers a lot of flexibility and some experimentation is suggested to determine what works best for your site.

Interesting idea but I heard meta refreshes have been looked at negatively as well from SEs. http://www.seobook.com/archives/000297.shtml
