XML Sitemap Missing

A sitemap lists URLs that are available for crawling and can include additional information like your site's latest updates, frequency of changes and importance of the URLs. This allows search engines to crawl the site more intelligently.
Robots.txt http://seznam.cz/robots.txt

Great, your website has a robots.txt file.
Analytics Missing

Web analytics let you measure visitor activity on your website. You should have at least one analytics tool installed, but It can also be good to install a second in order to cross-check the data.

Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 6 blocking script resources and 1 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:

  Consider Fixing:
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 7.7KiB (70% reduction).

  • Compressing https://image6.pubmatic.com/AdServer/PugMaster?rnd=14881141&p=49307&s=0&a=0&ptask=ALL&np=0&fp=0&mpc=0&spug=1&coppa=0&gdpr=0&gdpr_consent=&sec=1&kdntuid=1 could save 4.3KiB (77% reduction).
  • Compressing https://image6.pubmatic.com/AdServer/PugMaster?rnd=14881141&p=49307&s=0&a=0&ptask=ALL&np=0&fp=0&mpc=0&spug=1&coppa=0&gdpr=0&gdpr_consent=&sec=1 could save 2.5KiB (74% reduction).
  • Compressing https://i.imedia.cz/html/pub_sync.html?pmId=DD6A5587-B41C-43D2-89FC-001EEAECBAC2 could save 397B (48% reduction).

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:

Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 6 blocking script resources and 1 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.seznam.cz/2.0.239/js/polyfill/es5-only-clients.min.js
  • https://www.seznam.cz/2.0.239/js/client-babel-runtime.min.js
