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:

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 65% of the final above-the-fold content could be rendered with the full HTML response.
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 15.9KiB (17% reduction).
Minifying https://unity3d.com/sites/default/files/js/js_xm7x…PR4Cy_jvM6GVmLeL-W8.js could save 10.8KiB (21% reduction) after compression.
Minifying https://unity3d.com/sites/default/files/js/js_FwcA…A11Tu4SuhrXIFzuP7Nc.js could save 4.6KiB (12% reduction) after compression.
Minifying https://s.adroll.com/pixel/5OICZCZ5NJFPHKSELUHDHE/…DSGYF2BCIVATDI5EOQY.js could save 529B (14% reduction) after compression.
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 4.4KiB (35% reduction).
Minifying https://www.google.com/uds/api/search/1.0/584853a4…7d97114/default+en.css could save 3.9KiB (40% reduction) after compression.
Minifying https://www.google.com/cse/static/style/look/v2/default.css could save 555B (18% reduction) after compression.
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 3.8KiB (64% reduction).
Compressing https://img06.en25.com/i/elqCfg.min.js could save 3.8KiB (64% reduction).
Minify HTML

Compacting HTML code, including any inline JavaScript and CSS contained in it, can save many bytes of data and speed up download and parse times.
Minify HTML for the following resources to reduce their size by 840B (11% reduction).
Minifying https://unity3d.com/ could save 840B (11% reduction) after compression.
