谷歌向移動化領域又邁進了一大步，開始在索引中使用網站的移動版，而不是電腦版內容。

多年前，當更多人開始在手機和移動設備上進行搜索時，谷歌調整了算法，對在移動設備上展示良好的網站給予更高的排名。

之后在2016年末，谷歌宣布將開始調整搜索排名系統，優先展示網站的移動版而非電腦版內容。調整的原因是有時候電腦版網站當中會包含一些在移動版中無法顯示的元素，如果移動用戶點擊谷歌搜索結果，卻沒有看到他們想看的內容，他們就會不滿。

現在，經過一年半的試驗，谷歌宣布已經開始調整搜索算法，將優先顯示“遵循移動優先索引最佳實踐的”網站的移動版。也就是說，這些網站的移動版和電腦版所包含的內容及元數據完全相同。

軟件工程師張帆（音譯）寫道：“我們的抓取、索引和排名系統通常使用電腦版的網頁內容，如果電腦版內容與移動版內容存在太大的區別，這會給移動搜索用戶帶來麻煩。移動優先索引意味著我們將使用移動版網頁內容進行索引和排名，以更好地幫助用戶找到他們搜索的內容，主要是移動用戶?！?

但谷歌強調僅提供電腦友好內容的網站不需要恐慌，因為“相對于沒有通過這種方式抓取到的移動版內容或者電腦版內容，通過移動優先索引方式抓取的內容并不具有排名優勢。”

但考慮到谷歌在2015年進行的搜索排名調整，人們顯然應該提高自己網站的移動友好度。（財富中文網）

Google has made another big step in its shift towards mobile, by starting to link to the small-screen rather than desktop versions of many websites.

A few years ago, when more people started searching through their phones and tablets than on desktop computers, Google changed its algorithm to give higher rankings to sites that display well on a mobile device.

Then, in late 2016, the company said it would start steering its ranking systems towards the mobile rather than desktop versions of sites. This was because desktop sites sometimes include elements that are missing on their mobile versions—if a mobile user clicks on a Google result expecting to see something that then doesn’t show up, it’s frustrating.

Now, after a year and a half of experimenting with that latter shift, Google said it has started steering its search algorithm towards the mobile versions of sites that “follow the best practices for mobile-first indexing.” That essentially means sites that include the same content and metadata on both mobile and desktop versions.

“Our crawling, indexing, and ranking systems have typically used the desktop version of a page’s content, which may cause issues for mobile searchers when that version is vastly different from the mobile version,” wrote software engineer Fan Zhang. “Mobile-first indexing means that we’ll use the mobile version of the page for indexing and ranking, to better help our—primarily mobile—users find what they’re looking for.”

Google stressed that those running sites with only desktop-friendly content needn’t panic, as “content gathered by mobile-first indexing has no ranking advantage over mobile content that’s not yet gathered this way or desktop content.”

However, it was clear that people should continue to make their sites more mobile-friendly, due to the ranking changes Google introduced in 2015.
