## Proprietary Indices

- [Lighthouse AI Search Disruption Tracker](https://lighthousedata.io/data/products/ai_search_disruption_tracker): Annual trend series pairing the rise of AI search (AI Overview presence, AI marketing adoption) against the decline of classic organic CTR. Answers: 'how fast is AI search eating organic clicks — and does adoption hype match measured behaviour?'
- [Lighthouse Conversion Rate Trend](https://lighthousedata.io/data/products/conversion_rate_trend): Year-over-year trend series for the conversion-rate family: annual median per metric plus the YoY point delta between consecutive annual medians. The generic 'conversion_rate' metric mixes incompatible definitions (ecommerce site ~2-3%, landing page ~5-15%, email, paid ads, lead-to-customer ~10-30%), so it is published ONLY as per-definition segments (conversion_rate.<segment_key>) via the deterministic segment_split below; its mixed-definition aggregate is never published as a trend. Rows whose text context matches zero segments or more than one segment are unclassified and excluded.
- [Lighthouse Email Engagement Benchmark](https://lighthousedata.io/data/products/email_engagement_benchmark): Annual median / p25 / p75 benchmarks for core email engagement metrics, computed from the publishable corpus. Answers: 'what does a believable email program look like this year — and is my number actually good?'
- [Lighthouse Forward Benchmarks](https://lighthousedata.io/data/products/forward_benchmarks): Next-year forecasts for three headline series (email open rate, paid search CPC, conversion rate) via ordinary least squares on annual medians, published with a 95% t-distribution prediction interval. Answers: 'what should I budget against next year — with honest error bars?'
- [Lighthouse Marketing Cost Index (LMCI)](https://lighthousedata.io/data/products/marketing_cost_index): Single annual index (base year 2020 = 100) tracking the cost of paid customer acquisition, combining the CPC / CPM / CPL family as an equal-weight geometric mean of yearly median price relatives. Answers: 'how much more expensive is it to buy attention than it used to be?'
