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://cdn.pubnative.net/static/adserver/contentinfo.png (expiration not specified)
http://cdn.pubnative.net/widget/v3/assets/Uptodown_V3_320x100.css (expiration not specified)

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 54% of the final above-the-fold content could be rendered with the full HTML response.
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 3.1KiB (55% reduction).
Compressing https://d31qbv1cthcecs.cloudfront.net/atrk.js could save 2.2KiB (61% reduction).
Compressing http://cas.criteo.com/delivery/ajs.php?ptv=17&zone…F%2Fen.uptodown.com%2F could save 877B (46% reduction).
