koelner-zoo.de Safety Assessment

Website safety – both in terms of malicious actions as well as of the content itself – is a key factor that should not be underestimated. With not only viruses, but also harmful and hateful articles and opinions aplenty, it's important to protect our computers and friends and family from any harm.

1. Norton is one of the most renown security softwares and services in the world, provided by California-based cyber security experts Symantec. As such, we take their verdict on a website's security very seriously. Norton deems koelner-zoo.de as no_data. Experts report no annoyance factors. Norton did not find any computer threats. Hoorah! Lastly, the company has found no identity threats.
2. When it comes to great reputation, Norton and the company behind the software, Symantec, are up there with the best. When it comes to infamy, WoT is quite lonely. WoT (or Web of Trust) is, to put it mildy, perhaps the least reputable and trustworthy (oh, the irony) of sources that we can think of at this moment. The reason is simple - so many of the negative reports are false. And, what's even worse, WoT used to sell personal user data to third parties. Yeah, it's that bad. Still, we are including the data here for one reason - in case they are right, even one time out of a hundred. Just keep the context in mind and double-check... after tripple-checking. Got all of that? Ok, then. According to Web of Trust, koelner-zoo.de has a Trustworthiness rating of 60 (out of 10). We can't help but wonder what rating WoT themselves should receive... But let's not dwell. Take these ratings for what they are worth (which is to say, not always all that much).
3. Heard of Sucuri? You may have, despite the young age of the online security company. It was first started by Daniel B. Cid a few years back, in 2010, and is now owned by GoDaddy. Young it may be, but it already has proven to be quite a reputable expert and we tend to trust Sucuri's assessments. Now that that's clear, let's get to the point - Outdated Software detected. The website is also Not Currently Blacklisted (10 Blacklists Checked).

Website speed analysis

• The website load in around 0.5981 seconds. A very good result, this. Remember, search engines such as Google place a lot of their website ratings on its speed.
• The page HTML weighs approximately 139 kilobytes. Such an amount is nothing to worry about.
• The homepage of the website contains at least 60 images. Such an amount of images to have on a homepage is alright, so long as they are well compressed.
• Around 125 server requests have been made before the webpage was fully loaded. For the sake of users and ranking in search results, we hope this gets improved soon. Succife to say, we are not too enthusiastic about such a high number of server requests.

Detailed Alexa rank overview

ALEXA rating is based on the number of visitors a given page receives. The higher the visitor count, the higher the rating. Currently, ALEXA has over 4 million websites indexed. If you sense cynicism in our words, you're not mistaken - we think Alexa rating is overrated, to put it mildly. A website's worth (and contextual popularity) is more than the sum of the views. So take the rank with a grain of salt.
