Performance

Your page has 3 redirects. Redirects introduce additional delays before the page can be loaded.

Avoid landing page redirects for the following chain of redirected URLs.

  • http://youtube.com/
  • https://youtube.com/
  • https://www.youtube.com/
  • https://m.youtube.com/

Your page has 4 blocking script resources and 2 blocking CSS resources. This causes a delay in rendering your page.

None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

Remove render-blocking JavaScript:

  • https://m.youtube.com/yts/jsbin/mobile-blazer-nirvana-phone-vfl52KHON/core.js
  • https://m.youtube.com/yts/jsbin/mobile-blazer-nirvana-phone-vfl52KHON/watch.js
  • https://m.youtube.com/yts/jsbin/mobile-blazer-nirvana-phone-vfl52KHON/noncore.js
  • https://m.youtube.com/yts/jsbin/mobile-blazer-nirvana-phone-vfl52KHON/logged_out_users.js

Optimize CSS Delivery of the following:

  • https://m.youtube.com/yts/cssbin/mobile-nirvana-phone-mangled-vflOVhiIS.css
  • https://m.youtube.com/yts/cssbin/mobile-html5-player-mweb-2x-mangled-vflvHM-sG.css

Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.

The entire HTML response was not sufficient to render the above-the-fold content. This usually indicates that additional resources, loaded after HTML parsing, were required to render above-the-fold content. Prioritize visible content that is needed for rendering above-the-fold by including it directly in the HTML response.

  • Only about 2% of the final above-the-fold content could be rendered with the full HTML response snapshot:5.

Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.

Leverage browser caching for the following cacheable resources:

  • https://i.ytimg.com/vi/0NeuAFz7NFk/sddefault.jpg (5 minutes)
  • https://i.ytimg.com/vi/is7F-n5xiXg/hq720.jpg?sqp=-oaymwEhCK4FEIIDSFryq4qpAxMIARUAAAAAGAElAADIQj0AgKJD&rs=AOn4CLD2syiDMkRTA3eSDIQhJW6V1ad93w (5 minutes)
  • https://i.ytimg.com/vi/6ZfuNTqbHE8/hq720.jpg?sqp=-oaymwEhCK4FEIIDSFryq4qpAxMIARUAAAAAGAElAADIQj0AgKJD&rs=AOn4CLDCv5qJfxHHcNCzzHJZl5Gw1seO1w (2 hours)
  • https://i.ytimg.com/vi/i23aUei_7ig/hq720.jpg?sqp=-oaymwEhCK4FEIIDSFryq4qpAxMIARUAAAAAGAElAADIQj0AgKJD&rs=AOn4CLDWQrLIMfnJOCkGd3z-vC_wcQivgA (2 hours)
  • https://i.ytimg.com/vi/kXIa6uxBVRU/hq720.jpg?sqp=-oaymwEhCK4FEIIDSFryq4qpAxMIARUAAAAAGAElAADIQj0AgKJD&rs=AOn4CLA-32IIYGvHGXWA5ruNBvaYGXYMAA (2 hours)

Properly formatting and compressing images can save many bytes of data.

Optimize the following images to reduce their size by 6KiB (38% reduction).

  • Compressing https://yt3.ggpht.com/-2Si7CTpzGag/AAAAAAAAAAI/AAAAAAAAAAA/YN7Ka115V88/s68-c-k-no-mo-rj-c0xffffff/photo.jpg could save 1.5KiB (37% reduction).
  • Compressing https://yt3.ggpht.com/-Wu_k28Kxbpg/AAAAAAAAAAI/AAAAAAAAAAA/eJ5-MrqZZjc/s68-c-k-no-mo-rj-c0xffffff/photo.jpg could save 1.5KiB (46% reduction).
  • Compressing https://yt3.ggpht.com/-_DMSPt1vZaw/AAAAAAAAAAI/AAAAAAAAAAA/sSVARCDuXwE/s68-c-k-no-mo-rj-c0xffffff/photo.jpg could save 1.4KiB (46% reduction).
  • Compressing https://yt3.ggpht.com/-058HlQo6Dfc/AAAAAAAAAAI/AAAAAAAAAAA/h3mTqyvMa8E/s68-c-k-no-mo-rj-c0xffffff/photo.jpg could save 985B (38% reduction).
  • Compressing https://yt3.ggpht.com/-TI5ffZo0Qd4/AAAAAAAAAAI/AAAAAAAAAAA/glgeFHJ0Sto/s68-c-k-no-mo-rj-c0xffffff/photo.jpg could save 343B (24% reduction).
  • Compressing https://yt3.ggpht.com/-Dt0hmpZLxII/AAAAAAAAAAI/AAAAAAAAAAA/eDY7TF6sTsw/s68-c-k-no-mo-rj-c0xffffff/photo.jpg could save 254B (17% reduction).
