What is Source Impact?
Source Impact is a metric that evaluates the influence and contribution of a source — such as a website, social media account, news outlet, or influencer — within the digital ecosystem. It goes beyond counting mentions and assesses how much visibility and engagement a source can generate for a brand.
Key elements that define Source Impact include reach, engagement, and authority of the source. A single mention from a high-impact outlet can be more valuable than hundreds of mentions from low-visibility sources.
Why is Source Impact important?
Monitoring Source Impact allows brands to:
- Identify valuable sources that amplify their visibility.
- Benchmark channels and understand which media types matter most.
- Refine communication strategy by focusing on the sources that drive conversation effectively.
- Prioritize resources towards outlets, platforms, or influencers with the greatest proven impact.
Example of Source Impact in action
A company tracking its online presence might see that a mention in a leading news website generates wider visibility and engagement than dozens of smaller blog posts. By evaluating Source Impact, the company can understand which sources truly elevate brand presence.
What can be measured with Source Impact
- Impact per source: score assigned to individual sites, outlets, or accounts.
- Channel-level impact: which platforms (news, blogs, social media) carry more influence.
