Here it is, Drum-roll Please...
* Write and Publish Golden Content *
You've probably heard it before. If you think you've already achieved this and checked it off your list, think again. Utilize tools like woorank.com and Google Analytics to see how others (including search engines) are responding to your content. Pay attention to your content-to-code ratios. Check for property keyword density, links, spelling and grammar. Ensure your titles, descriptions, h1's and body content are all on par with each other.
Many web designers and SEO experts will highly advise that you do NOT attempt any other SEO strategies until this single (and most important) step is completed.
Hopefully we just saved you thousands of dollars.
