HTML Metatags
Title
Živě.cz – O počítačích, IT a internetu
The title has an optimal length. Search engines typically displays the first 50–70 characters of a title tag. If you keep your titles under 70 characters, our research suggests that you can expect about 90% of your titles to display properly.
Description
Nejčtenější web o počítačích, IT, internetu a spotřební elektronice. Každý den články, aktuality a videa.
The description has optimal length. Keep in mind that the "optimal" length will vary depending on the situation, and your primary goal should be to provide value and drive clicks.
Encoding
UTF-8
You should always specify the encoding used for an HTML page. If you don't, you risk that characters in your content are incorrectly interpreted. This is not just an issue of human readability, increasingly machines need to understand your data too.
Language
cs Czech
Identifying the language of your content allows you to automatically do a number of things, from changing the look and behavior of a page, to assisting search engines in extracting information. If part of the page uses text in a different language, you can add a language attribute with a different value to the element that surrounds that content.

As a general rule, search engines do not interpret the content of image files. The text provided in the <img alt> attribute enables the site owner to provide relevant information to the search engine and to the end user.
H1-H6 Tags Information

For search engines, <H> tags helps understand the structure of the text on a page better. For users, headings are like anchors in a wall of text, navigating them through the page and making it easier to digest. The <h1> tag reinforces the core keyword(s) found in the <title>, <description>, and the <body>. We recommend that the <h1> tag includes keywords that reflect the contents of the page and that it is not longer than 150 characters in length, but don’t overuse the tags and the keywords in them. Keep it readable for users.

Line 623, ...<h1><a href="https://vtm.zive.cz/clanky/dobre-vedet-proc-chtit-hv...

Line 1619, ...<h1><a href="/clanky/zive-z-pekingu-otestovali-jsme-velky-cinsky-...
Your H1 introduces the topic your page is all about, just as a title tells a reader what a book is all about. Remove redundant H1 tags from the page source, so that only one H1 tag exists.
H2
Line 601, ...<h2> <a href="/obchodni-sdeleni" class="ga-event-tracker idve...
The H2s are akin to book chapters, describing the main topics you’ll cover in sections of the article.
H3
Subsequent headers, H3s to H6s, serve as additional sub-headings within each section, just as a book chapter may be split up by multiple sub-topics.

Since search engines consider the content in iframes to belong to another website, the best you can hope for is no effect on SEO. Iframes tend to neither help nor hurt your search engine ranking. For this reason, it’s best to refrain from using iframes on main pages that you want to rank high in search engine results. Instead, fill high-priority pages with useful, unique content and save iframes for other pages.
Code To Text Ratio
Code To Text Ratio
5.31 %
A good code to text ratio is anywhere from 25 to 70 percent. This percentage refers to the visible text ratio, as opposed to HTML elements, image tags and other non-visible information. This has become especially apparent since search engines, such as Google, released the Panda update which placed importance on content-driven sites.
Favicons

Favicons are the little piece of graphic that represents your brand on browser tabs, bookmark lists, search history, search ads and even search results. These files are placed in a file called favicon.ico and placed in the root directory of a website. There are no direct SEO effects of having favicons. However, there may be indirect benefits such as increased usability of site and bookmarks. It makes your website look more professional and help a users to remember your site while browsing through multiple URLs. If you want to get mentioned benefits you have to specify icons for different web browsers and sometimes even for different mobiles.

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 37% of the final above-the-fold content could be rendered with the full HTML response snapshot:67.

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 7KiB (28% reduction).

Minifying http://code.jquery.com/jquery-migrate-1.2.1.js could save 2.2KiB (40% reduction) after compression.
Minifying http://www.zive.cz/Client.Scripts/Controls.Page.js?ver=6.0.7 could save 1.3KiB (20% reduction) after compression.
Minifying https://img.cncenter.cz/static/data/blesk/cncenter/cnc2Ad.js?v35 could save 1.3KiB (29% reduction) after compression.
Minifying http://www.zive.cz/Client.Scripts/jquery.cookie.js could save 1KiB (68% reduction) after compression.
Minifying http://spir.hit.gemius.pl/xgemius.js could save 637B (13% reduction) after compression.
Minifying http://www.zive.cz/Client.Scripts/jquery.query-object.js?v=0.1 could save 573B (26% reduction) after compression.

Compacting CSS code can save many bytes of data and speed up download and parse times.
Minify CSS for the following resources to reduce their size by 908B (18% reduction).

Minifying http://www.zive.cz/_rev2015/css/content-article.css?r=0.4.0502 could save 908B (18% reduction) after compression.

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 50% of the final above-the-fold content could be rendered with the full HTML response snapshot:25.
