Kalin Karakehayov is a Bulgarian entrepreneur who describes himself as an SEO marketer, domainer, and giver, and who often notes that he has never held a traditional day job. He is the founder of SEO.Domains, widely regarded as one of the largest providers of expired and aged domains in the world, and of the domain startup Edoms, which runs a portfolio of more than 200,000 domains.

Kalin moved into SEO around 2008 and into domain investing around 2012. After private blog networks were hit by search engine penalties, he and his team built a large-scale operation around catching expired domains and reselling those with existing SEO value to marketers, agencies, and affiliates. SEO.Domains operates as an ICANN-accredited registrar out of Sofia, Bulgaria.

A former competitive chess player, Kalin credits the strategic, long-game thinking of chess for his approach to the domain market. Alongside his businesses he has founded non-profit initiatives including No Cheap Traffic, which targets harmful online advertising, and I Grow Younger, focused on personal development and mental health. He shared his playbook with the Fajela audience in the SEOBox episode below.
