From d7166c56b65905f23d0966c884033a55b765614e Mon Sep 17 00:00:00 2001 From: Flotapponnier <160007691+Flotapponnier@users.noreply.github.com> Date: Sun, 5 Jul 2026 12:48:57 +0200 Subject: [PATCH] seo: purge thin compare pages + benchmark-first title on products & compare (#908) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * seo: purge thin compare pages + benchmark-first title on products & compare Bing WMT audit 2026-07-05: only 2 of 5093 sitemap URLs indexed. Root cause: 4938 ad-hoc /compare/ pages emitted at ≥1 shared bench threshold, producing near-duplicate templates that starved crawl budget and hurt domain trust. Changes: - sitemap: hybrid threshold. Brand-whitelist pairs emit at ≥1 shared, others at ≥3. Drops from 4938 → ~226 ad-hoc + 21 curated = ~247 URLs. Preserves every commercial X vs Y pair users actually search for (helius-vs-mobula, alchemy-vs-moralis, chain-vs-chain, perp-vs-perp). - compare-pairs: remove jupiter-vs-raydium (raydium has 0 bench appearances so /compare/jupiter-vs-raydium 404s at render). - products/[slug]: title now leads with 'Benchmark {year}' + head-term match on ' benchmark' queries. Meta description ends with 'As of YYYY-MM-DD' for LLM citation extractability (LLM-mediated discovery drives ~80% of Bing query traffic). - compare/[slug]: title now leads with '{a} vs {b} Benchmark {year}'. Meta description is unique per pair (shared bench count + date) killing the identical duplicate signal that had Bing skipping pages. * seo: prose summary above the fold on /compare + /products Replaces the identical templated intro paragraph on both pages with a data-driven prose summary derived from live measurements. Kills the last piece of duplicate above-the-fold text so Bing sees genuinely unique substantive content per URL. /compare/[slug]: Before: 'Side by side OpenChainBench measurements. Identical layout, no editorial verdict...' (same on 247 pages) After: 'Codex leads on 2 of 4 shared benchmarks, Mobula on 2. Codex wins on aggregator-head-lag (128ms vs 195ms), wallet-labels- coverage (42.8% vs 38.1%). Mobula wins on metadata-coverage (96.9% vs 89.1%), network-coverage (80 vs 42 chains).' /products/[slug]: Before: 'Moralis performance benchmarks, live across 2 categories. Reproducible measurements, open methodology.' (same on 104 pages) After: 'Moralis is measured across 2 live OpenChainBench benchmarks, with 1 #1 finish: NFT collection metadata (ranks #1, 96.9% p50), Wallet labels coverage (ranks #2 of 5, 42.4% p50).' Falls back to a neutral sentence when the provider's p50 data is missing (cold ISR, harness restart) so cold pages don't render a lie. * chore(lint): exclude standalone sub-apps from main frontend lint infrastructure/monitoring-ui and infrastructure/prom-admin are independently deployed Next.js apps (own package.json + Railway config, own build/lint/typecheck pipeline). Scanning them from the main frontend's lint pass caused every unrelated PR to fail on their pre-existing warnings that the sub-app maintainers can fix in their own dedicated PRs. worker/ is the materialize worker (own package.json + Railway config), same reasoning.
