Data Sources
本站所有数据均可追溯至下列来源之一。评测页面注明每项指标的抓取时间。
| Source | 提供的内容 | Timeliness |
|---|---|---|
| SEO2AIO crawler (SEO2AIOBot) | Every measured check: homepage HTML and headers, response timing, robots.txt, sitemap, llms.txt, host variants, 404 behavior — with per-check evidence | At submission time; at most one crawl per site per 30 minutes; timestamp on every review |
| RDAP registry records (rdap.org) | Domain registration dates for the domain-age check — public registry data, no key | Fetched with each review; registries update on their own schedule |
| Tranco research list (tranco-list.eu) | Global domain-popularity ranks (top 1M), aggregated from major traffic datasets — powers the authority check; being unlisted never subtracts points | Refreshed monthly |
| Own review database | Aggregate statistics (averages, grade distribution) behind Ask the Data and the public API | Live from cache |
Not used: commercial backlink/link-index data, live keyword-ranking data, and map-profile (Google Business Profile) data — checks depending on these say "not measured" instead of estimating. 数据可能随时不完整或被修订；请在采取行动前对照原始来源进行核实。
