About website sitemap(.xml)

Sitemap is a xml format document that lists URLs with metadata in websites, originally introduced in 2005 by Google, and now supported by all the well-known search engines, which can help webmasters to inform search engines about the pages on their sites that are available for crawling, so it’s also an important part of SEO(Search Engine Optimization).

The metadata in the sitemap of a certain URL contains the last updated datetime, the frequency of page changes, importance, relative to other URLs in the site, than makes search engines more intelligently crawl and display the site.

[Google] HTTPS as a ranking signal

原文 : HTTPS as a ranking signal

大意是Google很重視安全,除了自家產品預設都是走https外,也希望讓整個網路世界更佳的安全,所以網站有沒有使用https來保障傳輸之間的加密也成了Google搜尋引擎排序演算法的一部份,但目前比重仍然低於其他項目,例如[內容品質]這個項目,但為了鼓勵所有網站從http轉到https,之後可能會增加權重

然後接下來幾個禮拜Google會發布一些優秀的實作細節資訊來幫助大家更容易使用TLS加密,並且避免犯上一些常見的錯誤,例如要選擇怎樣的憑證、protocol-relative URL之類的,實在是就甘心…

所以走https可能會變成SEO要做的事情之一、而免費的StartSSL可能又會突然爆走然後暫停申請xD?

不知道之後Extended Validation、憑證的class、簽憑證的機構對於ranking的影響又是多少?
