Do stand friends know that the host is the basis of the site, host of good or bad directly affect the fate of the site. Only a stable host is very conducive to search engine spiders crawl, will not affect the inclusion and ranking.
If the site hosts are not stable, search engine spider every time to the site can be opened or not open, then the search engine will assume that the site can not crawl the new page, will reduce the number of spiders crawling and update the number of times, if the host can not open the long time, the search engine will determine that the site has been closed, Not only the rankings without a trace, the site will also be severely deleted included in the number of Seoer, the site will be sentenced to death, how cups! So stable host, SEO is the full necessary factor of one of the important SEO significance.
Stable host is so important to SEO, then how do we choose a suitable site for their host better optimize the site, the following to share under the purchase method:
1. Select multi-line virtual host.
Consulting host is a single virtual host or dual-line virtual host, many people in the domestic use of telecommunications, but there are many in the use of Netcom or unicom, if it is only one line, will cause a lot of people will not open, estimated that the potential customers have not been patient waiting for your site.
2. The program environment supported by the virtual host
See whether to support their own programs, whether or not to give the corresponding database virtual host Server Common there are two kinds: one is windows; one is Liunx. Windows is a versatile space to support ASP,. NET, PHP, JSP, and so on; Liunx hosts only support a few programs, such as PHP and CGI. So before purchasing must consult clearly what the host support program, do not buy the wrong.
3. What are the limitations of the mainframe?
Common hosts are: IIS restrictions, traffic restrictions, CPU limits. Any of these three items should be asked clearly at the time of purchase. Restricting IIS is to limit the number of people online at the same time, to see their own needs properly bought. Limit the flow of the host, see the situation to buy, need large flow do not buy. Limit the best not to buy CPU, because it is equivalent to limit your traffic and IIS, if you IIS super or traffic is too large will lead to excessive CPU usage, will cause the site can not open.
4. Access speed of virtual host
Speed This is very critical, the general virtual host service providers have a demo of the IP or site, you can ping, see how the link speed, the general words of the domestic 60MS, foreign 200MS or so are normal, but also to help open the test of friends from different areas.
5. The stability of the virtual host
The stability of this to use before the clear, buy before you can let good friends recommended, practice is the best. If the recommendation of a friend did not find the right, the choice of more well-known IDC service providers, may Zooey site will not open, not worth the candle. Here to friends recommend a host-host, very stable, speed is also good, and Yan Yan is also good, hope that friends useful good stable host also to share out, so that when the purchase will have more and better choice.
6. How many stations are there under the same IP host?
Check the host with the IP under the number of sites if not buy independent IP, the best check before the purchase. Usually a virtual host can set up hundreds of thousands of sites, if a virtual host of the number of sites, he should have more CPU and memory and the use of server arrays, if from the virtual host Distributor to buy virtual host, they in order to achieve the highest profit, Set up as many Web sites as possible on a single host. and the virtual host server is not prompted, resulting in slow access to the Web site, more important if the same IP site appears to be the phenomenon of search engine punishment, then our own site will be the corresponding joint punishment, resulting in the site's ranking drop or in the search engine was cleared. Everyone in the online search has a free software-through the domain name to view the number of sites on the virtual host tools, before buying the best to see under the host to buy how many sites, there is no penalty.
The above is my humble opinion of the host and SEO relations, welcome everybody to correct to add!
