We ran into an interesting problem this week: a client was having issues getting certain pages of its website indexed in Google. The pages would resolve fine, the meta data was accurate, but for whatever reason these pages would not index in Google.
We examined the code and found that the links were actually implemented as Redirects. After further research we realized that this handful of redirects failed to tell the browser 301 Permanent Redirect. We changed around the coding to accomodate for this... it will probably take a couple of days for Google to index these pages but at least we were able to fix the problem.
Long story short: if you are using redirects, make sure that you have a return a response status or you will run into the same indexing problems with Google. Incorrectly programmed redirects can cause SEO issues.
Here is a great resource for correctly setting up the 301 redirects.
