It's a worrying sign more than anything, really, as websites with meta keywords often tend to be spammy. |
Load time | 2.9449 seconds on average | Load speed is a concern and should be improved if and when possible. |
Alexa global | 943 973, as last updated | According to Alexa, the website's popularity is not exactly high. Take this rank with a healthy pinch of salt. |
Total links on homepage | We found 495 links | Honestly, this is a strange amount of links for a homepage. |
Page HTML size | 108.9KB | How do we put this... improvement is quite necessary. Load speed is a very important factor in so many ways! |
Website server | Server appears to be online. The IP address for the server is 43.245.220.197. | It's unfortunate, but despite our best attempts, we failed to gather enough data to provide a meaningful insight at this time. |
What, all that information was not enough? You want... more? Right, then. You asked for it.
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.
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.
Let's see what technical information we've managed to gather:
