Attack points

Feature sections ('Realtime', 'Vector', 'Storage', 'Authentication') are one sentence each — no definitions, limits, or pricing anywhere in 979 words.measuredReaders searching 'what is Supabase' need what it does, what it costs, and where it breaks; a structured explainer with a pricing table serves decision-stage intent this tile list ignores.

The React code sample appears twice verbatim and the Lovable customer story is duplicated back-to-back.measuredVisible copy-paste duplication is a thin-content tell; a clean, non-duplicated explainer with original examples reads as more trustworthy to both readers and ranking systems.

No publication or update date and no version numbers; the only figures are undated vendor quotes ('$10M ARR', '2,000+ employees').measuredUndated claims look stale in 2026; a dated, sourced guide with current Postgres version and pricing as of Nov 2026 wins freshness and AI-overview citations.

No pricing, free-tier quota, or self-hosting cost content exists in the H2 tree.measuredCost is the top unanswered question for hosting buyers; owning 'Supabase pricing' and 'Supabase self-hosting cost' captures a high-intent segment the homepage never addresses.

No comparison or migration content ('vs Firebase', 'vs Neon', 'migrate existing Postgres').inferredComparisons and migration guides pull mid-funnel searchers who already know the product; a vendor pitch page cannot rank for 'vs' queries without a side-by-side table.
