Website Evaluation and Review In-Depth

If the basic information we presented you with above is not enough, get ready to dive in much deeper!

Website speed analysis

• The website load in around 3.2271 seconds. Ah. Well. We were hoping for better results... We would urge the website owners to improve load speed as soon as possible.
• The page HTML weighs approximately 5.9 kilobytes. Such an amount is nothing to worry about.
• The homepage of the website contains at least 5 images. Such an amount can be considered spot on and should not impact the load speed of the website in any negative way.
• Around 6 server requests have been made before the webpage was fully loaded. This is a good number of server requests. As every request made increases the time it takes to load the page, such a low amount of requests probably improves page load time.

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.

Host Server Details

Servers are physical storage devices that contain all the files and databases associated with a specific website, sometimes more than one. At times, a server makes up several virtual devices - separate servers used for shared hosting (tends to be cheaper). Entering website address into the address bar of your browser starts the request process during which your browser contacts the server and asks for specific files and database entries in order to display the requested website.

• Server IP for this website is 211.43.212.238.
