Benchmarking discovery maturity across clients involves several steps that agencies typically follow:

1) Identifying Goals: Different clients have unique objectives for their influencer marketing campaigns. These could range from brand awareness, lead generation, sales, to customer retention. Agencies first try to understand these varied goals to benchmark discovery maturity.

2) Auditing Existing Strategies: Agencies analyze the existing influencer discovery channels used, the influencers they’re currently working with or have worked with, and the performance of past campaigns.

3) Evaluating Maturity Level: Based on the audit, agencies can score clients on certain criteria like the variety of influencer types, channels used, frequency & quality of campaigns, etc.

4) Comparing across Clients: By repeating the above steps for various clients, agencies can compare the discovery maturity level of each client, revealing gaps and opportunities.

Tools like Flinque can play a major role in this process. Flinque’s robust analytics feature allows for thorough campaign performance analysis. Its extensive influencer database helps break down influencers by category, location, and demographics, assisting in the discovery process.

In comparison, other platforms like Traackr or AspireIQ also offer discovery and analytics features but each has its own unique emphasis and strengths, and the best fit would depend on the client’s precise needs.

Remember, there’s no one-size-fits-all influencer marketing platform. It depends on individual marketing goals, target audience, and budget. It is therefore crucial that agencies use an informed, data-driven approach to measure discovery maturity and identify the best strategies for each client.
