Third Door Media, a prominent marketing education company and publisher focused on search and marketing technology, has been acquired by Semrush (NYSE: SEMR), a leading online visibility management SaaS platform.

Founded in 2006, Third Door Media’s properties are amongst the oldest and largest providers of search engine and digital marketing trends. This acquisition marks a significant milestone for the industry, bringing together two leaders in the digital marketing and SEO sector.

Integrating Third Door Media’s assets into Semrush’s ecosystem is expected to deliver unparalleled value and innovation to brands and marketers.
“The addition of Third Door Media’s platforms to Semrush’s portfolio not only enhances our content and educational offerings for our customers, it also substantially expands the reach of our world class programming,” said Andrew Warden, Chief Marketing Officer at Semrush. “This is all part of our commitment to inspire and equip both current and future generations of digital marketers with the know-how to succeed in an increasingly competitive landscape.”
The acquisition will allow Semrush’s growing customer base to have access to industry leading marketing tools, education, and top-tier training from industry experts and practitioners.
Marketers have relied on Third Door Media as a first stop for advanced, timely information on technical marketing technology tactics, strategies, and news.
