XML Sitemap Missing

Your website does not have an XML sitemap - this can be problematic.

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

We didn't detect an analytics tool installed on this website.

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.

  Should Fix:
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/2.0.197/js/polyfill/es5-only-clients.min.js
  • https://www.seznam.cz/2.0.197/js/client-babel-runtime.min.js

  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 5.4KiB (69% 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 4.4KiB (77% reduction).
  • Compressing https://i.imedia.cz/html/pub_sync.html?pmId=3A2AC1C5-8DF8-440F-B4BE-C7B6DC751AAD could save 397B (48% reduction).
  • Compressing https://i.imedia.cz/html/www.seznam.cz/reklama.html?url=https%3A%2F%2Fwww.seznam.cz%2F could save 348B (48% reduction).
  • Compressing https://i.imedia.cz/js/sync_codes.js could save 275B (46% 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:

  • https://geo.seznam.cz/static/js/geo.js (expiration not specified)
  • https://www.seznam.cz/favicons/stream/episode/5c436c0b0397cb086cd70000/400/225 (30 minutes)

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 1.4KiB (20% reduction).

  • Minifying https://i.imedia.cz/html/cmp.html could save 477B (28% reduction) after compression.
  • Minifying https://h.imedia.cz/html/adform_sync.html could save 340B (27% reduction) after compression.
  • Minifying https://c-ko.imedia.cz/imp?k=19e2ff6d-bca6-48ea-9d9c-8f5c5135b238&f=0&r=cMSVaT4O6Uwx3L0CKCFTxnnbR1w-12-1 could save 285B (12% reduction) after compression.
  • Minifying https://i.imedia.cz/html/pub_sync.html?pmId=3A2AC1C5-8DF8-440F-B4BE-C7B6DC751AAD could save 217B (26% reduction).
  • Minifying https://i.imedia.cz/html/www.seznam.cz/reklama.html?url=https%3A%2F%2Fwww.seznam.cz%2F could save 103B (15% reduction).

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 2KiB (15% reduction).

  • Minifying https://login.szn.cz/static/hpbox/hpbox.js?1545236843 could save 849B (23% reduction) after compression.
  • Minifying https://gacz.hit.gemius.pl/xgemius.js could save 809B (12% reduction) after compression.
  • Minifying https://h.imedia.cz/js/sid.js?server=h.imedia.cz could save 207B (11% reduction) after compression.

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/2.0.197/js/polyfill/es5-only-clients.min.js
  • https://www.seznam.cz/2.0.197/js/client-babel-runtime.min.js
  • https://www.seznam.cz/2.0.197/js/client-init.min.js
  • https://www.seznam.cz/2.0.197/js/client-bundle-page-hp.es5.min.js
  • https://www.seznam.cz/js/api/login.js
  • https://www.seznam.cz/2.0.197/szn-select/szn-select.bundle-full.es3.min.js
