Perhaps the most relevant statistics data that we could gather is presented here:
| Data type/Website parameter | Status or value | Our findings |
|---|---|---|
| Site title (meta) | N/A | Sticking to between 50-60 characters for meta title length is a good idea. The length of this website's meta title is 3. |
| Website meta description | Stable and free standard Prolog implementation. Targeted primarily at research and education. Windows, Linux and Unix versions available. Comes with a visual debugger and a GUI environment. | The length of the meta description is 189 characters. Google recommends up to around 280-320 characters at the most. |
| Website load speed | Approximately 0.0864 seconds | Website load speed is on a good level, great! But if an improvement can be made, it's always for the better. |
| Rank by Alexa | 126,901 | We are not fans of the Alexa rank, but if we base our assumptions on it, the website is not that popular. |
| Global rank by Quantcast | 515,511, after last update | Based on the gathered data, Quantcast does not consider this website to be popular. Take it for what it's worth. |
| Pages linking back | We counted 12 | Such a low amount of backlinks is insufficient and either shows the website is of low quality, or does not reach a wide audience. |
| Size of page HTML | 3.2KB | This is a very good result, as search engines prioritize websites that are quick to load. |
| Server data | Server seems to be online. IP adress for this domain is 23.235.40.249. | The location of the server is in Amsterdam, North Holland, Netherlands. The hosting service is provided by a known, trustworthy company. |
| Status of domain | Date of registry: 2001-12-17 19:28:14 | Due to lack of data, we can't provide a meaningful insight. swi-prolog.org has been registered at Hosting Concepts B.V. d/b/a Openprovider |
The basic overview not enough? Let's dive deeper.
A website is not just Quantcast ranks and meta information. There is a whole lot more to it. Let's give it a proper look now, shall we?
| Data type/Website parameter | Status or value | Our findings |
|---|---|---|
| Categories of the website | Computers Programming Languages Prolog Implementations Reference Libraries Library and Information Science Technical Services Cataloguing Metadata RDF Applications |
These are not only the possible categories the website falls into, but also areas of interest of the main target audience. |
| Similar websites | learnprolognow.org gprolog.org amzi.com visual-prolog.com eclipseclp.org |
While we can't speak with a hundred percent certainty, these website seem to fall into the same category as swi-prolog.org. Thus, they probably target the same audience and, likely, keywords. |
The following statistics are provided only as an approximation. We can't guarantee the numbers are absolutely correct, but we do believe they are very much within the ballpark and, as such, can give a pretty good idea about the popularity of this website.
Let's start with some telling numbers and then break it all down.
| Data type/Website parameter | Status or value | Our findings |
|---|---|---|
| Average visit time | 3:22 | This is a good amount of time for visitors to spend on the website on average, great result! |
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.
QUANTCAST is very similar to Alexa, though perhaps enjoys an overall better user opinion even if, by comparison, the data processing company's rank index is smaller. The main interest of QUANTCAST is real-time audience analysis, so again the rank is based on traffic. QUANTCAST gathers this data mainly for advertising purposes of other companies. We know that, so far, QUANTCAST has ranked 58,591,776 websites, give or take a few. With all of this said, Quantcast rank is not really any more useful than that of Alexa and most similar ranking systems. Few of them, if any, take context into account and rate websites purely on traffic numbers (guesstimated, in so many cases). It's by far not the most accurate representation of a website's worth.
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.
If you need more raw data, here's what we managed to gather:
