我們發現有許多網站成功轉換，並對搜尋排名和流量造成小幅影響。Wayfair 大型零售網站 SEO 行銷總監 Brian Wood 表示：「我們已成功將 Wayfair.com 遷移至 HTTPS，對 Google 排名或 Google 自然搜尋流量沒有多少影響。很高興在此宣布，所有 Wayfair 網站現在都採用完整的 HTTPS 技術。」CNET 是大型科技新聞網站，一樣也有類似的經驗：CNET 技術工程部副總裁 John Sherwood 表示，「我們在上個月成功將 CNET.com 遷移至 HTTPS。從那時起，我們的 Google 排名或 Google 自然搜尋流量沒有任何變化。」
如果網站含有廣告，網站擁有者在遷移大量網站時，也應密切監控大型網站遷移時的廣告成效和收益。過去 3 年來，透過 HTTPS 放送的 Google 廣告流量比例大幅提升。來自 Google 來源的所有廣告一律支援 HTTPS，包括 AdWords、AdSense 或 DoubleClick Ad Exchange；直接銷售的廣告 (例如透過 DoubleClick for Publishers 放送的廣告) 仍須設計為支援 HTTPS。這表示遷移至 HTTPS 之後，來自 Google 來源的廣告在網站上的顯示不會有任何變化。許多發布者在成功完成 HTTPS 轉換作業後都發現了這種情況。Washington Post 的程式輔助廣告總監 Jason Tollestrup 表示，「轉換至 SSL 對 ADX 收益沒有任何實質影響。」

In the interest of a safer web for all, at Google\nwe've worked alongside many others across the online ecosystem to better understand and address\nthese challenges, resulting in real change. A web with ubiquitous HTTPS is not the distant future.\nIt's happening now, with secure browsing becoming standard for users of Chrome.\n\n\nToday, we're adding a\n[new section to the HTTPS Report Card in our Transparency Report](https://www.google.com/transparencyreport/https/metrics/)\nthat includes data about how HTTPS usage has been increasing over time. More than half of pages\nloaded and two-thirds of total time spent by Chrome desktop users occur via HTTPS, and we expect\nthese metrics to continue their strong upward trajectory.\n\n\nAs the remainder of the web transitions to HTTPS, we'll continue working to ensure that migrating\nto HTTPS is a no-brainer, providing business benefit beyond increased security. HTTPS currently\nenables the [best](https://istlsfastyet.com/)\n[performance](https://blog.chromium.org/2013/11/making-web-faster-with-spdy-and-http2.html)\nthe web offers and powerful features that [benefit](/web/showcase)\nsite conversions, including both new features such as\n[service workers](/web/fundamentals/getting-started/primers/service-workers)\nor offline support and\n[web push notifications](https://www.mobify.com/insights/google-web-push-notifications-case-study/),\nand existing features such as\n[credit card autofill](/web/updates/2015/06/checkout-faster-with-autofill)\nand the\n[HTML5 geolocation API](/web/updates/2016/04/geolocation-on-secure-contexts-only)\nthat are\n[too powerful to be used](https://www.chromium.org/Home/chromium-security/deprecating-powerful-features-on-insecure-origins)\nover non-secure HTTP. As with all major site migrations, there are certain steps that site owners\nshould take to ensure that search ranking transitions are smooth when moving to HTTPS. To help\nwith this, we've posted\n[FAQs](/search/docs/crawling-indexing/site-move-with-url-changes#http-to-https-migration-faqs)\nto help sites transition correctly, and will continue to improve our\n[web fundamentals guidance](/web/fundamentals/security/encrypt-in-transit/why-https).\n\n\nWe've seen many sites successfully transition with negligible effect on their search ranking and\ntraffic. Brian Wood, Director of Marketing SEO at Wayfair, a large retail site, commented: \"We\nwere able to migrate Wayfair.com to HTTPS with no meaningful impact to Google rankings or Google\norganic search traffic. We are very pleased to say that all Wayfair sites are now fully HTTPS.\"\nCNET, a large tech news site, had a similar experience: \"We successfully completed our move of\nCNET.com to HTTPS last month,\" said John Sherwood, Vice President of Engineering and Technology\nat CNET. \"Since then, there has been no change in our Google rankings or Google organic search\ntraffic.\"\n\n\nSite owners that include ads on their sites also should carefully monitor ad performance and\nrevenue during large site migrations. The portion of Google ad traffic served over HTTPS has\n[increased dramatically](https://transparencyreport.google.com/https/overview) over the past 3 years.\nAll ads that come from any Google source always support HTTPS, including AdWords, AdSense, or\nDoubleClick Ad Exchange; ads sold directly, such as those through DoubleClick for Publishers,\nstill need to be designed to be HTTPS-friendly. This means there will be no change to the\nGoogle-sourced ads that appear on a site after migrating to HTTPS. Many publishing partners have\nseen this in practice after a successful HTTPS transition. Jason Tollestrup, Director of\nProgrammatic Advertising for the\n[Washington Post](https://developer.washingtonpost.com/pb/blog/post/2015/12/10/moving-the-washington-post-to-https/),\n\"saw no material impact to AdX revenue with the transition to SSL.\"\n\n\nAs migrating to HTTPS becomes even easier,\n[we'll continue](https://security.googleblog.com/2016/09/moving-towards-more-secure-web.html)\nworking towards a web that's secure by default. Don't hesitate to start planning your HTTPS migration today!\n\nPosted by [Adriana Porter Felt](/search/blog/authors/adriana-porter-felt) and Emily Schechter, Chrome Security Team"]]
