Proven Track Record

The selected agency should have a portfolio of results and case studies that demonstrate they’ve achieved the result you’re currently looking for, and for similar types of brands and industries to yours.

Social Specialism

The agency should offer customized strategies tailored to each client's specific needs, rather than a one-size-fits-all approach. Expertise across multiple social media platforms is crucial, as is the ability to create engaging, platform-specific content.

Data-Driven

All good agencies back up their social, creative, influencer and paid strategy with data. Not only are they able to demonstrate the ROI they're driving, but they showcase the logic behind why they’ve made particular decisions when tweaking the strategic approach to the scope of work they’re delivering for you.

Industry Leaders

Agencies that have won multiple awards show signs that they’ve been recognised within the industry and that they produce quality work, which is recognised by industry people. They should also be at the forefront of industry trends and social media platform changes, ensuring they and their clients stay relevant in the ever-changing market.
