Website Performance – The Geeky Part

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

eru.cz In Detail

As we've mentioned before, traffic is not a key metric. However, the target audience does say a lot about what's been done to optimize the website, as well as what should be done going forwards. Let's see if we have any useful information here.

eru.cz Website Safety

Now this is rather important. With viruses and malware so dominant these days, website safety is among the key ratings. It's importance is such that a website marked as unsafe is more than likely not to rank at all, let alone on the first page. Now, some sources are more reliable than others, but we'll try to present you with all the information we've managed to gather, along with some relevant commentary.

1. Out of all the security solutions we've managed to include, Norton stands tallest. The cyber security company behind this software, Symantec, has a well deserved reputation. As such, we trust their analysis and suggest you do, too. If they deem a website less than safe, there's probably a real reason for it. It can't be absolutely reliable, but as close as makes no difference, we think. Symantec deems eru.cz to be no_data. According to Symantec, no annoyance factors have been found. No computer threats were found. And finally, no identity threats were come across.
2. Even though we are including WoT (or Web of Trust) in this report - after all, any source is an important source when given context - it's nowhere near as reliable as, say, Symantec/Norton. We would not trust WoT all too much, but it's better to be falsely warned than falsely safe. Just be sure to double-check using other sources, as WoT has been less than trustworthy (oh the irony) over the last few years. According to WoT, eru.cz has a Trustworthiness rating of 64 out of 100. Child Safety has been rated at 96 (out of 100). Just remember - no grain of salt is too big here. These ratings can be blatant lies.
3. Sucuri is cool. Purchased a while back by GoDaddy, it's an online security expert company started in 2010 by the founder Daniel B. Cid. That makes it quite young, but don't mistake apparent lack of decade-long experience of the company itself for lack of quality data. According to Sucuri, No Malware Detected by External Scan. And lastly, the website is apparently Not Currently Blacklisted (10 Blacklists Checked).

eru.cz Visitor Information

Absolute accuracy is accessible only by the webmasters. If you keep that in mind, perhaps you will find out approximate numbers of some use.
Where appropriate, we'll add an insight, but the numbers themselves speak clearly enough, eh?

Website load speed analysis

• The homepage takes approximately 0.4367 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 48.7 kilobytes. We don't think 48.7 KBs is something to worry about.
• There are at least 10 images on the homepage of this website. We are glad to say that such an amount should not impact the load speed of the website. Great result!
• We've counted at least 28 server requests before the homepage was fully loaded. Every server request made increases the load time of a website. Thankfully, this is a pleasingly low amount.

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.

• eru.cz takes up 489 309 place globally, according to Alexa. We made sure to update this information on 2018-01-29.
• Compare the current rank to all-time best of 261 941, which this website enjoyed on 2016-02-22.
• Over the last three months, the position has changed by -66046.
• On the other end of the scale, the worst rank ever was 999 111, rated on 2016-07-20. 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 689 013.
• When compared to Czech Republic websites, eru.cz ranks in 5 669 place.

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 89.233.146.80.
• Server appears to be online.
