12 Eliminate render-blocking JavaScript and CSS in above-the-fold content

Your page has 18 blocking script resources and 10 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:

4 Enable compression

Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.


Enable compression for the following resources to reduce their transfer size by 33.8KiB (69% reduction).

Compressing http://ads.nicovideo.jp/assets/js/ads-2.27.0.min.js could save 31.9KiB (70% reduction).
Compressing http://notification.nicovideo.jp/res/notify.js?140901 could save 1.2KiB (53% reduction).
Compressing http://xid.i-mobile.co.jp/RestoreXidToMediaStorage.html could save 789B (59% reduction).

2 Prioritize visible content

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 64% of the final above-the-fold content could be rendered with the full HTML response.

2 Minify JavaScript

Compacting JavaScript code can save many bytes of data and speed up downloading, parsing, and execution time.


Minify JavaScript for the following resources to reduce their size by 11.8KiB (44% reduction).

Minifying http://nicovideo.cdn.nimg.jp/uni/js/nicolib/Sugges�uggestSearch.js?170209 could save 6.8KiB (50% reduction) after compression.
Minifying http://nicovideo.cdn.nimg.jp/uni/js/nicoheader/nic�cationHeader.js?150618 could save 3KiB (42% reduction) after compression.
Minifying http://nicovideo.cdn.nimg.jp/uni/js/nicoheader/siteHeader.js?171031 could save 859B (30% reduction) after compression.
Minifying http://nicovideo.cdn.nimg.jp/uni/js/personal_frame.js?161215 could save 675B (42% reduction) after compression.
Minifying http://nicovideo.cdn.nimg.jp/uni/js/zero_index.js?1702092 could save 563B (25% reduction) after compression.

1 Minify CSS

Compacting CSS code can save many bytes of data and speed up download and parse times.


Minify CSS for the following resources to reduce their size by 2.3KiB (20% reduction).

Minifying http://nicovideo.cdn.nimg.jp/uni/css/zero_index.css?170830 could save 1.7KiB (20% reduction) after compression.
Minifying http://nicovideo.cdn.nimg.jp/uni/css/zero_common.css?171031 could save 574B (24% reduction) after compression.

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 61% of the final above-the-fold content could be rendered with the full HTML response.

6 Leverage browser caching

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:

http://ads.nicovideo.jp/assets/js/adsSimple-1.3.0.min.js (expiration not specified)
http://embed.enquete.nicovideo.jp/static/js/enquete.js (expiration not specified)
