What are advertising agencies?

An advertising agency is a company that’s dedicated to assisting clients research, set up, and execute target advertising campaigns. These campaigns may include print ads, social media ads, paid search advertising, television ads, and more.

How do ad agencies get paid?

Top advertising agencies may have different ways of charging clients. Some may ask for a monthly retainer for ongoing account upkeep. Additionally, some firms could request to be paid a percentage of the ROI generated through the ads they create.

How can advertising agencies help my business?

Advertising agencies can help businesses educate their customers on their products and services. With an advertising partner, businesses can create memorable, measurable, and compelling strategies or campaigns. Advertising agencies also enable businesses to increase customer reach and build better brand awareness. By investing in advertising, businesses have a greater chance of gaining an advantage over their competitors.

What kind of ROI (return on investment) should I expect when hiring an advertising agency?

Businesses should anticipate seeing a tangible return on their investment when partnering with an advertising agency if the right measures and resources are implemented. Businesses should monitor key performance indicators (KPIs) such as customer acquisition cost (CAC), revenue growth, and return on ad spend (ROAS). Typically, these metrics don’t appear instantaneously after a campaign ends but rather after a few weeks or months.
