Factors that affect slow page loading

2. First, DNS domain name resolution

   When the browser makes a request to the server, first there will be DNS resolution, so that the site URL to resolve to a specific IP address, in this step, can do a lot of work. For example, many small sites use a single-line IP, Portal construction Company's many sites are used in the telecommunications single-wire IP, but when the Netcom users open, the speed is surprisingly slow, at this time, we can use two-wire IP, telecommunications an IP, netcom an IP, and then use dnspod for intelligent judgment, Analysis, when the users of Netcom to visit our site, we use the IP of Netcom to respond, when the telecommunications users access, we use the IP of telecommunications to respond, so greatly accelerated the loading speed of the page. And the big website, is generally uses the CDN to accelerate (CDN's full name is the content Delivery network, namely the contents distribution net. The basic idea is to avoid the bottleneck and link of the Internet which may affect the speed and stability of data transmission, and make the content transmission faster and more stable. By placing the node servers in the network, a layer of intelligent virtual network based on the existing Internet, the CDN system can re-direct the user's request to the nearest service node according to the network traffic and the connection of each node, the load condition and the distance and response time of the user. The goal is to enable users to get the content they need, address the congestion of Internet networks, and improve the responsiveness of users to websites.

4. Second, the network environment where the server resides

   Here involves the hardware environment and some output settings, and some room even air-conditioning is not, so when the server to a certain extent, the temperature will be very high, it will be very easy to crash, some sites often open, there may be this reason, the general hosting server rooms are very demanding, such as temperature, humidity, dust-free, etc., so do site construction in the selection of servers, it is important to choose some of the environment better than the custodian, the other is its output bandwidth, if its output bandwidth is very limited, then access to your site will also have a great impact.

6. Third, the hardware and software aspects of the server

   Server is actually a computer, the performance of this computer will affect our SEO effect, we can go to see their own server hardware configuration, as far as possible to configure, stable performance, in addition to its system software selection is also very important, Now we use a lot of basic is Windows host and Linux host, under the same conditions, the Linux system will be stable a lot, almost rarely crashes, few problems, the corresponding Windows host problem frequency is much more, so now a lot of people choose to use the Linux host, Linux with Apache, the performance is very stable, so maintenance will be much easier.

8. Iv. procedures used by the website

   Website used by the program will also affect the SEO effect, for example, most people use CMS system, in the blog, ASP with more Zblog, and PHP with more than WordPress, in fact, WordPress program than ASP performance much better, Many of its functions have taken into account the SEO, maintenance is very convenient, and zblog is worse, in some foreign trade website, you can choose Mengeto Program, Zencart. These are good SEO friendly programs
