on October 1, 2015

Publishing Agreement Expands Network Reach With More Quality Ad Real Estate

LOS ANGELES, Oct 1, 2015MANTIS, the largest cannabis-friendly ad network, and Grasscity, a leading digital community for marijuana culture and cultivation, announced that all Grasscity properties have officially joined the MANTIS family of publishing partners.

logosWith more than 600,000 members, over 10 million posts, and millions of pageviews per month, the Grasscity community is a lively meeting place for many cannabis enthusiasts. The forum’s influence in the growing sector of the industry is unrivaled, providing marketers with quality ad real estate — especially nutrient/soil, equipment, lighting, and other ancillary companies looking to stake their claim in a developing market. Grasscity Magazine, an international digital news syndication agency, covering relevant topics within the cannabis industry and beyond, has also implemented MANTIS’ ad tags and is now displaying ads powered by MANTIS on its web pages.

“The partnership is a win-win for both parties; MANTIS expands its offering with more highly segmented ad real estate, and Grasscity gets access to a network of advertisers and top-notch ad software to manage everything with ease.”

– Matt Price, CEO of MANTIS

Utilizing MANTIS’ powerful marketing platform, existing Grasscity advertisers are now able to segment their audience based on a wide variety of requirements, including the ability to target by geo-location, age, device, time of day, and more. MANTIS’ proprietary ad software allows the Grasscity team to focus on other tasks, like expanding the already-popular Grasscity shop.

By adding a key publishing partner like Grasscity to its network, MANTIS has effectively generated more ad inventory for its current and future advertisers while solidifying its position as the leading marketing platform in the cannabis niche. The network now collectively reaches over 10 million (unique) monthly readers across more than 150 cannabis-friendly websites, more than any other network.
