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 0.1039 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.

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.

• blackhole.sk takes up 766 170 place globally, according to Alexa. We made sure to update this information on 2018-01-18.
• Compare the current rank to all-time best of 409 299, which this website enjoyed on 2015-04-15.
• On the other end of the scale, the worst rank ever was 992 041, rated on 2017-12-30. 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 727 397.

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 37.9.168.56.
• Server appears to be online.
