Website SEO Analysis
In-Depth

Detailed Website Analysis

The basic overview not enough? Let's dive deeper.

Page speed overview

• It takes around 0.1442 seconds for the homepage to fully load. This is a very good result, as search engines prioritize websites that are quick to load.
• It's worth to note the HTML of the page is around 16.1 kilobytes in size. A good result that should not impact load speed in any negative way.
• Judging by tags, the homepage contains at least 1 images. A great amount! Not too many, at least. Images should not impact page load speed negatively.
• Our database tells us around 3 server requests are made before the homepage is loaded completely. This is a pleasingly low number of server requests and adds to the improvement of website load speed.

Host Server In-Depth

What is a server? It's basically a physical storage device (one that, sometimes, makes up several virtual servers for the cheaper shared hosting) that holds all the files and databases associated with a specific website or websites. Obviously, it's a touch more complicated than that (servers also have processors), but the essence is quite simple - your browser contacts the server, which then sends all the neccessary information and files to your computer. Each physical server has a unique IP address assigned to it, too, for easy recognition.

• The current IP address for this website's server is 104.25.69.103.
• Server seems to be online.
