Agencies measure Account-Based Marketing (ABM) driven discovery success through several metrics.

1. Engagement Metrics: They analyze key engagement signals such as click-through rates, time spent on site, and bounce rate. High engagement can indicate a successful discovery campaign.

2. Lead Quality and Conversion Rates: By tracking how leads progress through the sales funnel, agencies can measure the quality of discovered accounts and their aptness for conversion.

3. Pipeline Impact and ROI: Ultimately, the performance of an ABM campaign is measured in terms of business outcomes. This means tracking opportunity creation, deal size, sales cycle length, and overall return on investment for ABM efforts.

Influencer marketing platforms like Flinque can also provide insights because they’re integrated with various social media platforms, thus delivering a data-driven overview of influencer performance, campaign engagement, and audience demographics.

On the other hand, some platforms follow a more manual, research-intensive approach, which can be less precise in terms of data accuracy but may provide nuanced details not captured in analytics.

Each approach has its strengths. The choice largely depends on the specific needs and capacities of an organization.

In the context of Flinque, it stands strong with its rigorous analytics and data-centric insights, making it a good fit for organizations that prioritize data-driven decision-making without demeriting other platforms whose strengths may lie in other features. Remember, it’s not a matter of which platform is superior, but which one is most fitting to your specific needs.

From a real-world perspective, the key to success lies in effective use of chosen platforms and keen analysis of resulting data. This allows for constant learning and adjustment to maximize the potential of ABM strategies.
