You have to remember "good" is a relative term. The white hat forums want you to believe that good content is original and unique content that will engage your visitors to make them want to return to your page and recommend your site to their friends.
Good luck with that!! LOL
Actually, even if you do have good content by that definition you still need to get visitors to find you. You still want to show up in the serps when people search for terms related to your website. If everyone else is trying to have "original and unique content" then what is it that will make the search engines think your content is better than the rest.
Read the reply aReJay made again. That's some really good advice. As far as SEO is concerned "good content" means pages that have been optimized for SEO as much as possible. You can read the
Basic SEO practices for newbies thread in the White Hat SEO forum to get a good idea where to start with onpage SEO. Then continue browsing the WhiteHat SEO and BlackHat SEO forums to learn even more.
There's a lot to this idea, it's actually what the Google algorithm was designed to measure. Natural backlinks are great, but they're also impossible to control. You can make a website with the best content you can and still people might not start making links. Natural backlinks are about the most unreliable thing you could ever count on, and yet that's what your told you need to get.
Good luck with that too! LOL
A natural backlink would be something like Joe Smith in Arizona has a blog on the same topic as your website, he see's your website, likes it, and posts an article on his blog with a backlink to your site. That isn't something you can control, but You can actually go to a free blog site, make up a name like Joe Smith in Arizona, create a blog on the same topic as your website, then post an article on that blog linking back to your main website. The best thing is that Google can't actually tell the difference between those two backlinks.
So it turns out you're in luck. It actually is possible to get natural backinks, or at least simulate that you have natural backlinks. Now to do that on a large scale involves some work. Google does want natural backlinks so you need to make sure that even on a large scale they appear to be natural. If you want some ideas on how to do that go read
