I want to create some TEST pages, with different seo efferts on each, (different keyword density, titles etc) and see what does my site best etc etc so say for e.g. i made a test page on test1.domian.com and that turned out to high keyword density and search engines saw it as spam and banned it would that ban the entire domain.com from the engine or just the sub-domain? any advice will helpfull and no i do not plan on spamming the engines, i am doing this to help myself learn what they do and do not like.
I don't think anyone knows for certain. I think that a lot of Google banning is done manually by Google employees who do not live in the U.S. and are paid about the same as the people who make tennis shoes. Either way, it's only around $10 to register a new domain.
yeh i think i should just register a new domain just in case i do get banned or whatever, only thing is ill have to wait till end of the month till i get paid
