priority - 8Eliminate render-blocking JavaScript and CSS in above-the-fold content

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

Remove render-blocking JavaScript:

http://fast.fonts.com/jsapi/074b2034-0974-462a-b78c-3dfcd18c7c2b.js
http://cooper.edu/sites/default/files/js/js_FPCjTN…F4DLH7jOj-CG4bfjAMI.js

http://cooper.edu/sites/default/files/css/css_9OP8…eHS2lOPiAOA.css?oig6mc

priority - 2Enable 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 21KiB (73% reduction).

Compressing http://cooper.edu/ could save 21KiB (73% reduction).

priority - 2Prioritize 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 32% of the final above-the-fold content could be rendered with the full HTML response.

priority - 1Minify 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 10.7KiB (19% reduction).

Minifying http://cooper.edu/sites/default/files/js/js_FPCjTN…F4DLH7jOj-CG4bfjAMI.js could save 10.7KiB (19% reduction) after compression.

priority - 1Leverage 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://js.hubspot.com/analytics/1483653900000/316075.js (5 minutes)
http://www.google-analytics.com/analytics.js (2 hours)

priority - 0Minify 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 4KiB (14% reduction).

Minifying http://cooper.edu/ could save 4KiB (14% reduction).

cooper.edu Ping

Ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It measures the round-trip time for messages sent from the originating host to a destination computer that are echoed back to the source.

cooper.edu TRACEROUTE

Traceroute is a computer network diagnostic tool for displaying the route (path) and measuring transit delays of packets across an Internet Protocol (IP) network. The history of the route is recorded as the round-trip times of the packets received from each successive host (remote node) in the route (path); the sum of the mean times in each hop is a measure of the total time spent to establish the connection. Traceroute proceeds unless all (three) sent packets are lost more than twice, then the connection is lost and the route cannot be evaluated.

Your page specifies a fixed-width desktop viewport. Use a responsive viewport to allow your page to render properly on all devices.

priority - 4Size tap targets appropriately

Some of the links/buttons on your webpage may be too small for a user to easily tap on a touchscreen. Consider making these tap targets larger to provide a better user experience.

The following tap targets are close to other nearby tap targets and may need additional spacing around them.

cooper.edu HTML validation

Errors

Bad value “revision” for attribute “rel” on element “link”: The string “revision” is not a registered keyword.

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

Element “span” not allowed as child of element “time” in this context. (Suppressing further errors from this subtree.)

The text content of element “time” was not in the required format: The literal did not satisfy the time-datetime format.

Element “p” not allowed as child of element “h3” in this context. (Suppressing further errors from this subtree.)

Warnings

Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.

Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).

Empty heading.
