SparkToro
Rand Fishkin is one of the most influential people in modern SEO, not only because he co founded Moz, but because he helped shape how an entire generation of marketers thinks about search, visibility and audience research. Today he is CEO and cofounder of SparkToro, along with other ventures, and his current work is less about traditional keyword rankings and more about understanding where audiences spend time, who influences them and how brands can build demand before a search even happens. That makes him especially interesting in a top list of global SEO specialists, because his career shows how SEO has grown from a technical channel into a broader discipline connected to brand, content, distribution and market insight.
