Quick overview:
Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 3 blocking script resources and 4 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://www.bluetooth.com/layouts/system/VisitorIdentification.js
...
Optimize CSS Delivery of the following:
https://www.bluetooth.com/cassette.axd/stylesheet/769ad26ea8fe036ac3f5b4ce391fe8db189e63fd/resources/css/bootstrap
...
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:
https://www.bluetooth.com/layouts/system/VisitorIdentification.js (expiration not specified)
...
Reduce server response time
In our test, your server responded in 0.38 seconds. There are many factors that can slow down your server response time. Please read our recommendations to learn how you can monitor and measure where your server is spending the most time.
Optimize images
Properly formatting and compressing images can save many bytes of data.
Optimize the following images to reduce their size by 18.5KiB (12% reduction).
Compressing https://www.bluetooth.com/~/media/images/video-stills/meet_blue.ashx?h=157&la=en&w=300&hash=683F9362E9BD54A5C27C71FF743510858769228B could save 15.6KiB (11% reduction).
...
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 1.9KiB (57% reduction).
Compressing https://www.bluetooth.com/~/media/images/logos/logo.ashx could save 1.9KiB (57% 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 993B (12% reduction).
Minifying https://www.bluetooth.com/ could save 993B (12% reduction) after compression.
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 594B (43% reduction).
Minifying https://www.bluetooth.com/resources/js/jquery/jquery.cookie.js could save 594B (43% reduction) after compression.
