A good space is the first condition for a site to obtain a good ranking. The measurement criteria of a space are as follows:
1. Fast space speed
2. Good spatial stability
3. Sites under the same IP are of high quality
In view of the above three points, we can analyze it from the following aspects:
1. How to test whether the space speed meets the needs of your website
① Ping is the simplest way to test the speed of local access to the website, but this Ping is inaccurate in certain procedures due to many factors. You can also use the Super Ping of Webmaster Home to test the access speed within the national visit, the address is http://tool.chinaz.com
② Get a demo site from the space provider and test the speed in person.
2. Space stability is very important, and sites that are frequently down will definitely not have a high weight.
① Spatial stability is long-term, and it does not mean that the results can be tested in a day or two. We can use some detection tools. The domestically famous Monitoring Bao http://www.jiankongbao.com and the foreign Uptime Robot http://www.uptimerobot.com are both very good detection tools. Use them to detect a server. Stability, for example, it will automatically send email or text message notifications when it is down.
3. Once the space IP enters the blacklist, it will undoubtedly be fatal to the new website.
① For ordinary small business sites, it is enough to buy a virtual host, and many domestic virtual hosts share IPs. The disadvantage of shared IPs is that they are afraid that the IP will be blacklisted by Baidu or Google.
② What happened to being blacklisted? Spiders enter the site by IP. For example, the IP address is your house number. There are many sites under one IP. If a site is a spam site, and the spider crawls it several times and finds that the information on this spam site is of no value to us and is purely advertising, then the spider will think that this site has no practical significance. , will not crawl again or will crawl very little in the future, and the judgment is based on IP, then the site with the same IP will definitely suffer. In response to this situation, we can do the following things to avoid this situation: check whether the IP has entered the blacklist and then change the IP.
③ To check which websites have the same IP, you can use the same IP website query in Webmaster Home http://tool.chinaz.com/Same. Enter the IP or domain name and some sites will be listed (the judgment is based on the query history), so There are some discrepancies, and then we have to check whether the domain name is the same IP as ours. After confirming that it is on the same IP, we start to conduct some comprehensive SEO queries on the domain name. Generally speaking, as long as the domain name website has a few pages included, it can be considered that the website has not entered the sandbox, which means that the IP is normal and can be used, and there is no need to change the IP.
Based on the above 3 points, a good space will be screened out, which is beneficial to SEO! Of course, what Fendou Xiaodong talks about here is all about the domestic space, and the foreign space is more complicated (I have a year of purchasing and promotion experience before, and I also ran a host evaluation blog) I will definitely write an article for your reference when I have time.
