Challenge

Mac Lang Orillia was facing down steep competition, with regional competitors established for almost 100 years in the area. Unlike the competition, Mac Lang Orillia doesn't sponsor the local arena, stadium, or other traditional big-ticket promotional or marketing items - How could we win online?

Solution

We created a network to monitor the competition's every move on social media. We tracked their activity, posting, audience intent, and response. Reach Ecomm created a highly effective customer psychographic profile from the data and combined it with tight reporting.

Result

The result was a meteoric rise in the overall combined social audience between Facebook, Instagram, TikTok, LinkedIn and YouTube. We created content that spoke to the user, was directed with specific intent, and, most importantly - resonated with the target consumer. Our client is happy; we are too!

Challenge

Hubject’s marketing reports were inconsistent and lacked detail. Clear Click introduced a structured reporting framework for regular, in-depth updates. Budget planning was unclear due to minimal documentation, so a transparent media spend system improved allocation. High translation costs in Google Ads were reduced by leveraging machine translation and in-market partners, saving budget while maintaining effectiveness.

Solution

Clear Click streamlined Hubject’s reporting, reducing ad hoc requests by 40% and improving efficiency. Budget planning was optimised using data models, securing an extra £40K for digital channels. Google Ads translation costs were cut by £25K by focusing on high-volume markets, reallocating savings to other media. A targeted Google Ads strategy drove a 610% YoY increase in customer acquisition by refining geographic targeting and continuous optimisation.

Result

610% increase in new customers year-on-year. £40,000 saved by introducing budget modelling. £25,000 saved by most cost effective translation services.
