Welcome to the Q&A Forum

I believe this file is the base template for all the others.  So if you put it on the main one, it should be on the others.  That is why I suggested to add it and then view the code of the others to verify it is there as well.

The rel=canonical is based on the actual url structure.  So whatever your url structure is (your navigation), then the rel=canonical tag should match.

Run a detailed Linkdetective scan and start contacting each blog.

This type of marketing works better with larger sites.  When you have a simple website with just a home, about, contact, and pricing page, it is really hard to optimize a Contact page for something else then contact.  (it may be done, but I wouldn't focus on this).

Remember that you already have greenscreen in your url.  So if you really want to focus on different phrases, you may have to break apart or build more pages about what you do.  Or even have a section that is "what-is-greenscreen/"

With this site and only having 4 pages, I would focus on link building towards the home page.

Also, with taking a quick look you have a few other issues you should take care of.  The first is with Canonicalization.  As of right now you can access your home page with two different urls (seen as duplicate content).

• http://www.liveimagegreenscreen.com
• http://www.liveimagegreenscreen.com/index.html

I hope that helps.

I would be very careful on how you manage this right now.  It all depends on the old and new urls.  If this is something in Dev staging, like http://dev.examplesite.com, then it is alright to do everything possible to clean them up.  But if the new urls are going to be the new final urls, then you have to be careful.

The best thing you could do right now would be to password protect the new site.  That way there isn't a chance of anything getting to it.

All it takes is Google finding one link to the site then it will crawl from there.
