Site Performance and Stats
In Detail

Website Performance – The Geeky Part

What, all that information was not enough? You want... more? Right, then. You asked for it.

Website load speed analysis

• The homepage takes approximately 0.51 seconds to load. Load speed (and overall responsiveness) is such an important factor for both search engines and user experience, would you not agree? With that in mind, this is a very good result.
• The HTML of the website weighs in at around 102.7 kilobytes. We don't think 102.7 KBs is something to worry about.
• There are at least 85 images on the homepage of this website. This seems an ok number of images to have on the homepage.
• We've counted at least 128 server requests before the homepage was fully loaded. Oh my, this needs to be worked on. The more server requests are made, the longer it takes to load the page. Not a good result by any measure.

Alexa ranking in-depth

With over 4 million websites indexed (which can seem as a lot, or very little, depending on your point of view), Alexa is perhaps the oldest and certainly the best known ranking system, deservedly or not. The Alexa Global and Local ranks of a website are based on an approximate amount of visitors a given website receives. The more visitors, the higher the rank. The Alexa rank, be it Local or Global, should be taken with a pinch of salt. After all, visitor count is by far not the simple measure of a website's success it's made out to be. For example, a gardening website is never going to be as popular as a movie review website. It does not mean it's not popular within it's niche.

• ct.cz takes up 996 651 place globally, according to Alexa. We made sure to update this information on 2017-05-26.
• Compare the current rank to all-time best of 730 062, which this website enjoyed on 2017-04-28.
• On the other end of the scale, the worst rank ever was 996 651, rated on 2017-05-26. Compare that to the current rank to see a marked improvement, even if of debatable importance.
• Given all the numbers, the average Global rank is at 882 157.

Detailed Host Server Information

Similarly to how a hard drive or a modern SSD device holds your files, a server holds all the files the website needs to operate. To load a webpage, your browser needs to contact the said server and request files - strings of code that make up the website into what it is, including images, text and database entries. Each physical server has a unique IP address that is used by the browser to contact it.

• The website's server IP address is 160.218.161.61.
• Server appears to be online.
