Ahrefs Blog is one of the most authoritative SEO and content marketing publications on the internet, run by a tight-knit team of practitioners inside Ahrefs - the $100M+ ARR bootstrapped SEO software company. Led by CMO Tim Soulo, the blog pioneered 'product-led content' - a framework where every article must have real search traffic potential AND directly pitch Ahrefs as the solution. With 600,000+ monthly search visits, 284,000 newsletter subscribers, a Domain Rating of 91, and a YouTube channel with 664,000 subscribers, the Ahrefs Blog is both a masterclass in SEO and a primary driver of company growth - all without a single salesperson.
Amanda Natividad is VP of Marketing and Chief Evangelist at SparkToro, the audience research platform co-founded by Rand Fishkin.

A trained chef and former tech journalist before she was ever a marketer, Amanda brings a rare blend of narrative discipline, culinary generosity, and data-driven rigor to a field that often settles for one of the three. Her newsletter 'The Menu' reaches 16,000+ subscribers and was named by Forbes among the top marketing newsletters. She has 200,000+ combined social followers and has guest lectured at Columbia Business School, Cornell, Stanford, and the University of Washington.
