Optimization

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 Missing

Your website doesn't have a robots.txt file - this can be problematic.

A robots.txt file allows you to restrict the access of search engine robots that crawl the web and it can prevent these robots from accessing specific directories and pages. It also specifies where the XML sitemap file is located.
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.

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 56.8KiB (76% reduction).

  • Compressing https://10.im.cz/sos/3fb/de7/3fbde72126f696cac99b34948cfbe63a/duoroX%20sacivykon%20vanoce%20300x600.js could save 47.2KiB (78% 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:

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 1KiB (27% reduction).

Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 10 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/2.0.50/js/polyfill/es5-only-clients.min.js
  • https://www.seznam.cz/2.0.50/js/client-babel-runtime.min.js

Prioritize 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 59% of the final above-the-fold content could be rendered with the full HTML response snapshot:13.
