衡量网站在生成式搜索、答案引擎、AI 引用及传统搜索方面的准备程度。
This site's takeaway scores: SEO 94/100 (grade A) and AIO 88/100 (grade B), from 9 measured visibility categories. Strongest area: Search visibility (100/100); weakest: AI & answer engines (77/100). Strong-ranking sites meet an 85-point profile on these same checks — that is the yardstick for both scores.
SEO: 达到强排名指标. AIO: 达到强排名指标. 85分基准是指一个符合持续高排名网站通行做法的网站在相同检测项上所能获得的分数，是一个经过测量的参照标准，而非实时竞争对手排名。
每个类别均为一组加权实测检查项；无法量化的类别将从评分中排除，而非推测填充。
该网站无法测量此项，已排除而非估算: Local search.
各项得分由加权维度构成；贡献列精确显示每个维度对总分的加分值（权重在可测量范围内重新归一化）。各维度复用相同的底层检测项，不存在重复抓取。
