Detailed Website Analysis

The basic overview not enough? Let's dive deeper.

centrum.cz Data In-Depth

A website is not just Quantcast ranks and meta information. There is a whole lot more to it. Let's give it a proper look now, shall we?

centrum.cz Traffic Statistics

The following statistics are provided only as an approximation. We can't guarantee the numbers are absolutely correct, but we do believe they are very much within the ballpark and, as such, can give a pretty good idea about the popularity of this website.
Let's start with some telling numbers and then break it all down.

Page speed overview

• It takes around 0.3752 seconds for the homepage to fully load. This is a very good result, as search engines prioritize websites that are quick to load.
• It's worth to note the HTML of the page is around 15 kilobytes in size. A good result that should not impact load speed in any negative way.
• Judging by tags, the homepage contains at least 58 images. This is an ok number of images to have. Not too many, but not too few, either.
• Our database tells us around 119 server requests are made before the homepage is loaded completely. Wow, that's a lot. Certainly, so many server requests contribute to slower page load times.

Alexa rank up close and personal

Alexa, perhaps the oldest ranking system of its sort, bases it's website rating on approximated number of visitors of a specific page. In other words, the more visitors, the higher the global and local ranks. As of recently, Alexa has well over four million websites ranked. Having said all that, Alexa rank should be taken with a grain of salt. Or a massive bucketload. In other words, we think it to be greatly overrated, as it never takes into account how popular a website is within its niche.

• Alexa claims centrum.cz takes up 3,984 place globally, among all the indexed websites. We updated this information on 2018-01-17.
• Compare that to the best rank this website has taken 2013-11-26, which is 1,640.
• The delta of this rank over the last three months is around 54.
• As far as we know, the worst position for centrum.cz was 4,606 (on 2016-10-23).
• The average Alexa rank for centrum.cz is 2,948 at this time.
• It's worth to mention that in Czech Republic, centrum.cz is in 17 place.

QUANTCAST rating in detail

QUANTCAST is very similar to Alexa, though perhaps enjoys an overall better user opinion even if, by comparison, the data processing company's rank index is smaller. The main interest of QUANTCAST is real-time audience analysis, so again the rank is based on traffic. QUANTCAST gathers this data mainly for advertising purposes of other companies. We know that, so far, QUANTCAST has ranked 99,262,223 websites, give or take a few. With all of this said, Quantcast rank is not really any more useful than that of Alexa and most similar ranking systems. Few of them, if any, take context into account and rate websites purely on traffic numbers (guesstimated, in so many cases). It's by far not the most accurate representation of a website's worth.

• As reported by Quantcast, the website takes up 80,380 place globally. This rating was last checked on 2015-02-05.
• The best Quantcast rank of 11,119 was achieved on 2014-01-15.
• As far as we know, the worst position for centrum.cz was 298,676 (on 2014-08-07).

Host Server In-Depth

What is a server? It's basically a physical storage device (one that, sometimes, makes up several virtual servers for the cheaper shared hosting) that holds all the files and databases associated with a specific website or websites. Obviously, it's a touch more complicated than that (servers also have processors), but the essence is quite simple - your browser contacts the server, which then sends all the neccessary information and files to your computer. Each physical server has a unique IP address assigned to it, too, for easy recognition.

• The current IP address for this website's server is 46.255.231.48.
• Server seems to be online.
