Improving google rank and backlinks
 

I want to increase my backlinks for one of my domain names, If I did text only webpages with just one link to my domain name I want backlinked and put that page on thousands of subdomains would that improve my back links and google rank?

No. The google crawler is wise to that trick and compares IP's.

There are always ways to cheat with the search engines, but it's a dirty tactic. Not only will you be frowned upon by most web-developers but if the search engine catches you (and they often do), then you're banned from their listings for life.

Earn your search engine position by offering genuine unique content, optimizing your sites for search engines (without cheating), and do it the right way.
