We track three categories of metrics: visibility (what appears on page one of Google for your brand keywords, and how that changes over time), share of voice (the ratio of positive, neutral, and negative results in your top 10 and top 20), and brand mentions (volume, sentiment, and emerging threats across the web).
You receive regular progress reports with clear before-and-after comparisons. The reports show what's been suppressed, what's been built, what's currently dominant, and what's trending — so you can see the work and its impact, not just trust that it's happening.
