How to Choose Leading Digital Marketing Companies
The selection and review of agencies was a careful and impartial review. The assessment focused on key areas – client results, real stories and examples, and measurable metrics like ROI and traffic growth. Below is how the agencies were evaluated:
- Client Results: Agencies were assessed on real examples of successes; in some instances, both client reviews and clear metrics showing increases in traffic and ROI were used.
- Agency Experience: This was primarily gauged by the length of time in business, past successes from various projects and campaigns, and the agencies’ ability to apply best practices from different fields and businesses.
- Services: This assessment judged agency ability to offer a very broad range of services – SEO, link building, digital PR, content marketing (and SEO-friendly content creation), PPC, and paid media.
- Reputation and Credibility: Overall industry accolades, mentions and awards in publications, and credibility.
- Transparency: Agencies were assessed on openness in processes, reporting, and client expectations.
- Innovation: Specific programs about using AI-based strategies and unique campaign models reserved for specific uses.
- Global Capabilities: Agencies were viewed much more favorably if they could prove the capacity to service clients when operating in multiple languages and countries.
- Expert Evaluation: This area was to include expert oversight but mainly consisted of agency assessment in areas of experience, creativity, and real value offered to clients.
The agency’s size or revenue wasn’t factored into the evaluation; the focus was strictly on measurable outcomes and client results.
