About The Customer
Magazine Luiza is one of the largest retail chains in Brazil. The company was established in 1957 and has more than 600 stores across Brazil. The company's name, Magazine Luiza, was chosen in a local radio contest. Luiza was the first name of one of its founders, and the Portuguese word 'magazine' means 'department store' in English. The company launched its extensive website in 1999, which offers about 35,000 products to online shoppers.
The Challenge
Magazine Luiza, one of the largest retail chains in Brazil, was facing challenges in managing its Google AdWords campaigns. The company had a large number of tags on its website, which was making the tracking and management of its campaigns complex and inefficient. The company wanted to reduce the number of tags to a minimum and simplify the measurement and management of its campaigns. The company's IT team was handling all of the tag implementations, changes, and requests, which was time-consuming and inefficient.
The Solution
Magazine Luiza decided to deploy Google Tag Manager on its website to simplify the tracking and management of its AdWords campaigns. The company worked with digital firm Agência CASA to make the switch from its old system of changing or adding tags one at a time. With Google Tag Manager, the company was able to shift the management of tags from its IT team to its marketers. The time needed to plan and deploy a new tag dropped from around two weeks to as little as five minutes. The company was able to deploy 23 tags using Google Tag Manager.
Operational Impact
  • The company saw a 30 percent increase in return on investment (ROI) for its AdWords campaigns, thanks to better tracking and optimization via conversion tags that Google Tag Manager made possible.
  • The website also runs about eight percent faster.
  • The time needed to plan and deploy a new tag has dropped from around two weeks to as little as five minutes.
Quantitative Benefit
  • 30 percent increase in ROI for AdWords campaigns.
  • 8 percent increase in website speed.
  • Significant reduction in time needed to plan and deploy a new tag, from two weeks to five minutes.
