I have a basic business name.com and wondering if it still makes sense to buy other domains with keyword rich.coms and do the 301 forward to the main site. Will it help catch and direct the people searching those keywords or not really? I think its more about quality content now, but is this still helpful to do? Is it worth the $20 year/domain or does it hurt seo? I'm super green and trying to learn the basics. thanks!
