Tools for the Trade

We'll use the right amount of sugar to make your brand sweet.

Graphic Design

Having a crisp, consistent image is the foundation for any marketing campaign (digital or traditional). Graphic design is our bread and butter! We use the Adobe Creative Cloud to create captivating imagery for both print and digital platfroms.

Outbound Marketing

If your business is in need of direct, outdoor, video, or graphical advertising, Sour Marketing is here for you. From content creation to placement selection, we have the experience needed to help your brand break through the clutter.

Inbound Marketing

Inbound marketing focuses on adding leads and prospects to your sales funnel. A successful inbound strategy employs a wide range of channels with a focus on bringing customers 'inward' (hence the name inbound). Do you want to give inbound a shot? Sour Marketing can help.

Search Engine Optimization

Google has become the modern version of a library for both information and purchase decisions. In fact, you may have found us through a Google search! From AdWords to organic SEO placement, we'll help you get a "sweeter" search rank.

If you've got it, flaunt it!

These are some of our most recent projects.

PMG Intelligence

Digital Marketing

Before working with PMG Intelligence, their marketing efforts were predominantly traditional. To remain competitive in the modern marketing research industry, they need to modernize their marketing strategy. The goal is to set PMG up with an inbound marketing strategy. Using CRM, marketing automation, social media marketing, and search engine optimization, we are working towards making that goal a reality.

As a member of the organizing committee, Sour Marketing has helped build the YAM brand to what it is today. From the branding to the social media strategy, Sour Marketing has been there to help YAM with their great work in the Catholic faith.


Marketing Strategy

In 2016, Wilfrid Laurier University had its first ever TEDx event; the theme was "The Next 100 Years." Sour Marketing had representation on the organizing committee. Graphics were created, social media was managed, and a promotional video was created. The great work from all organizers ensured that TEDxWLU would be a huge success.
