You may decide to hire an online marketing agency if your marketing strategy is unclear or lacking and/or you’re struggling to generate leads. A full-service agency can help supplement your existing house marketing team by providing resources and knowledge you don’t already have access to and filling in any gaps.

These additional resources and value can help you get ahead of your competitors regarding visibility, reach, and engagement. Suppose you do not have an existing internal marketing team. In that case, an agency partner can help by taking over marketing responsibilities from you so you can focus on your core business or project goals.

Oftentimes, hiring a marketing agency can be more cost-effective than hiring full-time or even part-time employees, as it comes with salary, benefits, and overhead. By investing in an independent ad agency, you’re only paying for services. Online marketing agencies can also specialize highly in your product, service, or target demographic.

This specialization can mean decades’ worth of combined experience in your specific niche and goals. To track your ROI with a marketing agency, they typically provide extensive reporting and quality insights that allow you to track their impact and make long-term business strategic decisions.

Both in-house marketing teams and marketing agencies have pros and cons. An internal marketing team will be more familiar with your product and customer base, whereas a marketing agency will have to take the time to learn these things.

This is why it’s important to find a marketing agency with a clearly structured onboarding process where they take the time to understand and become experts in your product and customer personas. With the familiarity of in-house marketing teams, stagnation, and creative blocks can also sometimes occur. This is where a marketing agency can come in and bring fresh ideas, perspectives, and experiences.
