It was a great idea to gather audiences of those who have made conversions, so that next season, using remarketing, to target our products with special offers. This allowed us to save the budget for attracting new customers. Due to this, we were able to expand our customer base 1.4 times (per year). We added a branded search campaign, began to take 98% of all users who were looking for our brand and did not let them go to competitors. Advertising in gmails for those who were already our clients and their look-a-like audience gave a huge increase in sales, even in the off-season. After the first year of work, we replaced our strategy by 70% for 3 years, as we learned about new tools, began to understand the niche better and already understood where our points of growth were.
