Website SEO Analysis

Detailed Website Analysis

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

Page speed overview

• It takes around 0.4809 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 58.6 kilobytes in size. A good result that should not impact load speed in any negative way.
• Judging by tags, the homepage contains at least 25 images. A great amount! Not too many, at least. Images should not impact page load speed negatively.
• Our database tells us around 85 server requests are made before the homepage is loaded completely. Wow, that's a lot. Certainly, so many server requests contribute to slower page load times.

Alexa rank up close and personal

Alexa, perhaps the oldest ranking system of its sort, bases it's website rating on approximated number of visitors of a specific page. In other words, the more visitors, the higher the global and local ranks. As of recently, Alexa has well over four million websites ranked. Having said all that, Alexa rank should be taken with a grain of salt. Or a massive bucketload. In other words, we think it to be greatly overrated, as it never takes into account how popular a website is within its niche.

• Alexa claims sciencemag.cz takes up 953,214 place globally, among all the indexed websites. We updated this information on 2017-10-10.
• Compare that to the best rank this website has taken 2017-03-06, which is 490,919.
• As far as we know, the worst position for sciencemag.cz was 997,506 (on 2016-11-06).
• The average Alexa rank for sciencemag.cz is 727,308 at this time.

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 89.187.144.182.
• Server seems to be online.
