The website operates 24 hours a day. If the server fails, the users will not be able to access the website, thus missing some potential customers. In addition, the stability of the server will also affect the web performance in the search engines. If a website cannot be accessed for a long time or makes frequent errors, it will also cause the search engine to clear the pages that cannot be accessed during its multiple visits or updates, or even reduce the overall weight of the website.

Another important consideration is the available bandwidth. If a server sharing 100MB bandwidth is used and there is no guarantee of the minimum bandwidth, when other servers in the same room occupy too much bandwidth, your website might have server access timeout or network failure. If the search engine spiders would happen crawl to your web pages at this time, it would not capture any content information. That would leave a negative impression to the spiders.

If a virtual space is purchased, the space provider will generally limit the number of connections accessed. One space will be controlled to the number about 150. In our business practice, we should select the space according to the actual situation of the website. For example, if the peak volume of visitors showing at the same time is more than 150, you should choose one with less connections, otherwise, there would run timeout or much delay, which will also affect the friendliness of the search engine.
