So SEO is my thing as you’ve noticed. I love SEO probably because its just so quantifiable. You can see your target URLs climbing up the rankings and your traffic increasing in Google analytics, where as coding and other fun techy geeky things are great but how do you really know what you’re doing is actually good? Its quite subjective really.
SEO the failure or success is clear to see in the simplest of ways. Are all your keywords in the top 3 SERPs?
