Here is an overview of what we consider to be the key website statistics and information:
| Parameter name | Status | Comment |
|---|---|---|
| Website meta title | 程序员实验室 - C++基础教程 - C++ Tutorial | Search engines recommend title length of around 50-60 characters. The length of this title is 31. |
| Meta description | 针对入门级的C++基础教程，在线阅读，无需下载。本教程对C++主要知识点均有例证说明，清晰易懂，深受读者好评。关键词中英文对照，方便理解，更可为你打开阅读原版资料的大门。 | To make sure all the meta description is visible in search results page, Google recommends length of up to 320 characters at the most. This description has exactly 85 characters. |
| Keywords | C++基础，C++入门，C++，C++基础教程，C++ tutorial | We did not expect meta keywords to be used. It's a worrying sign more than anything, really, as websites with meta keywords often tend to be spammy. |
| Load time | 0.47 seconds on average | Website load speed is pretty fast. |
| Alexa global | 839 921, 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 47 links | This is a normal amount of links. |
| Page HTML size | 11.4KB | Load speed (and overall responsiveness) is such an important factor for both search engines and user experience, would you not agree? With that in mind, this is a very good result. |
| Website server | Server appears to be online. The IP address for the server is 162.210.102.65. | 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:
