The user experience has always been the core content of SEO work, good user experience can create and leave more customers for us. Based on this, in order to give users a good browsing experience, search engines are constantly adjusting and improving this work. And good user experience the first element is the speed problem, most netizens will have such an experience, after waiting for 5-8 seconds if a Web page has not been able to open, we often choose to give up browsing this page.

So, as the site webmaster, you are not lost a chance to win users? If you can find this problem in time and solve the adverse effects it brings to you in time, it is not too late to mend. But if you allow the Internet to be so slow over time, you will lose a large number of users. So test speed, fully understand your Web site to run the situation is particularly important. There are a lot of online speed measuring tools, we can borrow a group of these tools to the speed of their own site to diagnose, such as Baidu statistics with the site speed diagnostic function is very good.

I use the Web site of the virtual host is million nets, according to million network technician is in the intelligent multi-wire room (because before the blog because of the problem of the window advertising requirements million network replacement server, so switch to the intelligent multi-wire room), the following figure is the diagnosis of some of the data.

Data show that through the network Point page when open time is 0.39 seconds, faster than 95.3% of the Web site to open, and through the Telecom Point page takes 0.65 seconds, only faster than the 91.9.% Web site opened faster, the data reached the conclusion of the Netcom line users faster than the telecommunications, However, in my personal use of telecommunications broadband experience, the general situation next page completely open in 3-5 seconds, overall, the speed of access is good, the single diagnosis score is not high, which also put forward the diagnostic recommendations, gave the impact of the speed of the three factors, these three factors is what we need to pay attention to when doing the site, We do site optimization can follow these points to optimize the code structure and access speed.

I. Connection Network

The less time you have to request a connection to open a page, the faster it will be, as shown in the figure above, when my blog page is open, it has experienced 42 requests (a Web site with more than 33% requests), saving 18 connections. According to this author subdivided a few aspects.

1, Merge Domain name: will only have 1 resources domain name merge under other domain name

2, Merge JS: by merging the same domain name JS to reduce the number of network connections

3, Merge CSS: Reduce the number of network connections by merging the CSS under the same domain name

4. Cache static Resources: static resources with few changes can set up client caching to reduce requests

5, using CSS Sprite: Use CSS Sprite technology can reduce the number of requests

Second, download the page

Page opening speed is also affected by the size of the page, that is, the server request to send back to the page, the smaller the page size, the faster the speed of the Web page. The figure above shows that during the opening of my Site page, a total of 175.9 KB (more than 23% site bytes) can be downloaded to reduce 10.4 KB. This requires the use of compression methods to adjust, through the compression technology to reduce the volume of elements, so as to improve speed.

Third, open the page

Page content size, design and many other factors will affect the user browser to open the page speed. This requires us to start with the next two details:

1, JS location, in order to speed up the page opening speed, JS placed in the final page

2, the picture size declaration, to the size of the picture that did not require the page needs to be rendered again, its speed must be affected

The host itself configuration, environment and other factors, although the page opening speed also has some impact, but this is not the main factor, the site itself is really the main reason to affect the speed, so for how to optimize the internal structure of the site and code and other issues are critical. The above three aspects are the most direct and most common factors that affect the speed of page opening. Perhaps your site has done well enough, and perhaps a lot of details have not been done, then start with these details to improve it.
