ESBO started in 2015 with a simple belief: real authority is earned, not bought from a marketplace. While much of the industry turned link building into a self serve catalogue and an inbox full of automated pitches, we chose to stay boutique, to know our clients, and to hand pick every placement ourselves.

Over the years we built a network of more than 300,000 real websites across every niche, language, and authority level. We became known for the markets others avoid, the regulated and competitive niches like iGaming, crypto, finance, and health, where trust and domain authority are everything.

Today we are a distributed team working remotely across Europe and Southeast Asia, from our home base in Plovdiv, Bulgaria. We pair smart tooling, which we use to qualify domains and check Ahrefs so no site ever repeats, with real people who build the relationships and answer when you message. Technology finds the right sites. People earn the placements.
