I have a website and bought several domain names?

Merely linking things to the main website isn't enough. If none of the domains have any content of any value, they themselves will be low-ranked and thus be considered low-value links (or worse, if they're considered spam or junk, a negative influence on your main website!)


The best SEO is quality content, not trying to game the system. If you don't have quality content that prospective customers find valuable, no amount of trickery will compensate for that. Try to create good content that people find useful.
