Im currently trying to optimise an Internal page for my arcade, Can i still use methods like squidoo, directory submissions, hubpages etc...? If I have already used those methods for the index page on my arcade? Please could someone help thanks!
yes you can still use them , and to grow up in serach engine ... i will encourage you to also gather backlinks for them too
The internal pages can be optimized exactly like new domain names. In fact working on them and making them popular can be better and more convenient than launching new sites from the beginning. Subdomains or folders or internal pages need contents like the other sites and backlinks for rankings.
