I researched other advertisement agency's website to get a better idea how other agency's designed their homepage. I noticed many ad agencies use a large hero video on their homepage to show the work culture in their office. They also have different sections for each category like, "Who we are", "Careers", "Contact", etc.
I developed low-fidelity wireframes for their website to get a better idea on layout and the user's flow while scrolling and navigating their website.
I made a simple high-fidelity mobile version of the website, since most of their traffic comes from mobile users. I included a large hero image on the homepage and bold colors that matched their logo.
