Content is King/Content Doesn’t Matter
Some SEO bloggers think quality content is the only route to SERP success while others tend to downplay its importance in favor of other SEO techniques. As it turns out, they’re both wrong.
Quality content is very important, hugely important, but it doesn’t exist in a vacuum.
You can have the most fantastic content in the world but unless you’ve done the rest of your job, like good keyword research, it won’t matter much at all. On the other hand awesome keyword research without quality content won’t help much either.
Good SEO means balancing out various techniques to the most out of each one.
