Performance

Your page has 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.

Optimize CSS Delivery of the following:

  • https://q.bstatic.com/mobile/css/core/c6efdfabf75428ae49c2e70ee73575df00e9a187.css
  • https://r.bstatic.com/mobile/css/app/284f3f48afb0ec23aaf3987ff78a69892a034990.css
  • https://r.bstatic.com/static/css/fonticons_clean/102693ab649a7f3c2807170f8dc14ad9c9537126.css
  • https://r.bstatic.com/static/css/destfinder_icon_font/7f07255f20594d2ced60f1cbade8a16b52a7b047.css

Your page has 2 redirects. Redirects introduce additional delays before the page can be loaded.

Avoid landing page redirects for the following chain of redirected URLs.

  • http://booking.com/
  • https://booking.com/
  • https://www.booking.com/

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://tags.tiqcdn.com/utag/booking.com/main/prod/utag.js (5 minutes)
  • https://tags.tiqcdn.com/utag/tiqapp/utag.v.js?a=booking.com/main/201802220422&cb=1519942474807 (10 minutes)
  • https://www.googleadservices.com/pagead/conversion.js (60 minutes)
  • https://www.google-analytics.com/analytics.js (2 hours)

In our test, your server responded in 0.22 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.

Properly formatting and compressing images can save many bytes of data.

Optimize the following images to reduce their size by 989B (68% reduction).

  • Compressing https://r.bstatic.com/static/img/facebook/fb_icon_58x58/8f9fc05b2a9ac4456eef29d2e4d2bd7cb0a988d6.png could save 989B (68% reduction).

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 150B (24% reduction).

  • Minifying https://4228414.fls.doubleclick.net/activityi;src=4228414;type=funne910;cat=cross;u20=index;u27=0;ord=2403218e0006a1f1e3a2b815b455cdfc? could save 150B (24% reduction) after compression.

You have compression enabled. Learn more about enabling compression.

Your CSS is minified. Learn more about minifying CSS.

You have the above-the-fold content properly prioritized. Learn more about prioritizing visible content.

Your JavaScript content is minified. Learn more about minifying JavaScript.

Mobile Usability

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.

  • The tap target <label for="input_destination" class="search_hotels_subtext">Destinations,…ven an address</label> is close to 1 other tap targets final.
  • The tap target <div class="searchbox--rad…-purpose-label">Are you traveling for work?</div> is close to 2 other tap targets final.
  • The tap target <a id="newsletter_button_footer" class="newsletter_but…etter_hideable">Subscribe</a> is close to 1 other tap targets.
  • The tap target <a href="https://www.bo…_site_type=www" class="u-display:inli…te u-padding:5">Desktop version</a> and 4 others are close to other tap targets.

The text on your page is legible. Learn more about using legible font sizes.

The contents of your page fit within the viewport. Learn more about sizing content to the viewport.

Your page specifies a viewport matching the device's size, which allows it to render properly on all devices. Learn more about configuring viewports.

Your page does not appear to use plugins, which would prevent content from being usable on many platforms. Learn more about the importance of avoiding plugins.
