简介
我们为网站上的所有可索引对象创建了索引项。这些是搜索引擎能够访问的所有 URL。由于 WordPress 存储内容的方式，其中大部分将是“文章”（在 WordPress 数据模型中，页面也被视为“文章”）。因此，大多数网站上的索引项主要是文章。
我们为某些特殊内容创建了专门的索引项，以避免它们轻易地堵塞数据库。这尤其适用于日期归档页面和系统页面（搜索结果页、404 页面）。它们各自拥有一个索引项，用于存储我们的标题模板，以便在前端使用这些模板。
Which "things" get an indexable?
Posts
There are quite a few different types of using posts within WordPress. Only those that are publicly viewable should be considered indexable objects. Of course a post has to exist to be a valid Indexable object.

Post type archives
A post type archive will only have an indexable when the post type it's registered for is public.

Terms
A term has to be part of a registered, public taxonomy to be an indexable object.

Users
Only when a user has published posts that are public, do they get an author archive. At that point, they become an indexable object.
