IKEA's digital marketing strategy aims to increase online sales by 5% over one year. It will launch an interactive blog promoting home improvement projects for Millennials aged 25-40. Users can share stories and photos for a chance to win a $5000 monthly shopping spree. The blog, social media, Google ads, and SEO will drive traffic to the online store. The $10 million budget will be split between these channels, with performance tracked through Google Analytics.
