(2~3 best) reverse links: the link from home page to home page is a kind of cheating in itself. The anchor text in the article: derailment; Suggestion: (breadcrumb path) For example: Home > Technology is a hyperlink in China, and any inner page has anchor text pointing to the home page. 3, website content: the snapshot of blog class is faster, such as: wordpress, which is related to the content; At least one part is updated with the content update, so as to facilitate the update of the homepage snapshot.
