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) | 免费PDF图书-人类学PDF/TXT下载-人口学PDF/TXT下载-民族史PDF免费下载-文化人类学PDF图书下载-社会科学PDF图书下载 | Sticking to between 50-60 characters for meta title length is a good idea. The length of this website's meta title is 69. |
Website meta description | 免费PDF图书,人类学PDF免费下载,人口学TXT下载,民族史PDF/TXT下载,文化人类学PDF/TXT下载,社区PDF免费下载,图书馆学档案学PDF下载,语言文字PDF免费下载,社会科学理论TXT下载,社会结构和社会关系PDF免费下载,社会科学丛书、文集、连续出版物PDF/TXT下载,心理学PDF/TXT下载,公共关系PDF免费下载,统计学PDF/TXT下载,社会生活与社会问题PDF图书下载,社会科学类教材PDF下载,教育PDF/TXT下载,社会调查TXT下载,研究生/本科/专科教材PDF免费下载,文化人类学人口学PDF免费下载,社会保障PDF免费下载,新闻传播出版TXT下载,经典名家作品集PDF图书下载,民族学TXT下载,社会科学总论PDF免费下载,人才学PDF图书下载,社会学PDF免费下载,新闻出版TXT下载 | The length of the meta description is 363 characters. Google recommends up to around 280-320 characters at the most. |
Metadata keywords | 免费PDF图书,人类学,人口学,民族史,文化人类学,社区,图书馆学档案学,语言文字,社会科学理论,社会结构和社会关系,社会科学丛书、文集、连续出版物,心理学,公共关系,统计学,社会生活与社会问题,社会科学类教材,教育,社会调查,研究生/本科/专科教材,文化人类学人口学,社会保障,新闻传播出版,经典名家作品集,民族学,社会科学总论,人才学,社会学,新闻出版 | Oh. It's unexpected, to put it mildly, to see meta keywords still being used. After all, they are no longer a ranking factor and associate with spam more than anything else. |
Website load speed | Approximately 2.9426 seconds | It takes too long to load the website – we would suggest the webmaster to look into it. |
Rank by Alexa | 775,327 | We are not fans of the Alexa rank, but if we base our assumptions on it, the website is not that popular. |
Homepage links | Approximately 438 | Such an amount of links on a homepage might raise a question or two. |
Size of page HTML | 78.5KB | If it were up to us, we'd urge the webmaster to improve. The result isn't very good, you see. Just saying. |
Server data | Server seems to be online. IP adress for this domain is 43.245.220.197. | Due to lack of data, we can't provide a meaningful insight. |
The basic overview not enough? Let's dive deeper.
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.
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:
