CarGurus' sitemap lists 160,840 /research/compare/ pages, and in a sample of 19, five told search engines "noindex, nofollow", among them 2022 VW ID.4 vs 2023 Ford Mustang Mach-E and 2024 Pacifica Hybrid vs 2024 Ioniq 5. These are not thin pages: they show prices, listing counts, expert ratings, pros and cons and specs. The sitemap asks Google to crawl them while the page asks it not to index or follow them, and "ID.4 vs Mach-E" is exactly the kind of question shoppers now put to search and AI assistants. The new Content Engineer is hired to track where CarGurus content is cited in AI answers; these pages are the cheapest citations to win back.

Why it works
Pull every comparison URL in the sitemap with its robots tag and canonical. Join with search demand for each pair. Index pairs with real demand and complete data, with self-canonicals (and fix pairs that canonicalize to a noindex "customcompare" URL). Drop the rest from the sitemap so crawl effort goes to listings. Add a short written verdict and a link to matching listings on indexed pairs, then track rankings and AI citations for the top 500.
Comparison queries come from shoppers deciding between two cars, one step from searching listings. Each page already holds CarGurus' unique data (prices, deal counts, ratings); it only needs to be allowed to rank.

Risks and how to handle them
Indexing low-value pairs dilutes quality
Index only pairs with demand and complete data; keep the rest out of the sitemap.
Evidence
- Your websiteComparison pages sampled from the sitemap on October 23, 2026 (rechecked the same day): 5 of 19 return "noindex, nofollow", including 2022 Volkswagen ID.4 vs 2023 Ford Mustang Mach-E, 2024 Chrysler Pacifica Hybrid vs 2024 Hyundai Ioniq 5, 2024 Nissan Kicks vs 2025 Mazda CX-70 and 2022 Nissan Versa vs 2023 Tesla Model 3. These pages are full: prices, listing counts, expert ratings, pros and cons and specs. One sitemap URL (2023 Mazda CX-5 vs 2024 Toyota RAV4 Hybrid) canonicalizes to a "customcompare" URL that is itself noindex.Source
