do know that the site is very important to the user experience site, which we do SEO which is the most important factor in the heart repeatedly stressed, and search engines are constantly adjusting to make further improvements in this talent, are hoping to give the user a good browsing experience while on our site can affect the browsing experience is the first element is the opening page of time. A page in the 5 to 8 seconds to open yet, I think we did not patiently wait, directly off trouble, this also increases the bounce rate, but also the performance of the user experience is not good, how do we analyze our Open access to the site time and speed of it, there are many online speed online tool, I am here to introduce the statistical own site Baidu speed diagnostics.
my site is used by million net virtual host, network technicians, according to Wan is the smart multi-line room (because of his previous blog because there pop ads issue requirements million net replacement server, so the switch to the Intelligent multi-line engine room), below is part of the data after diagnosis.
test data points for the Netcom page open time 0.39 seconds, compared with 4.7% of the site opens a long time, and telecommunications point of time 0.65 seconds to open the page, more than 8.1% of the site open for a long time from diagnosis data, the user opens the Netcom line speed faster than Telecom's, but in my view the use of broadband telecommunications, home basically in 3 to 5 seconds to fully open access speed point of view is quite good, but the diagnostic score is not high, the back also gives the diagnostic recommendations, summed up the impact of the three pages long when open, rather these points is what we do when the site points to note, we do website optimization can optimize the code in accordance with these points to the structure and access speed.
First, connect to the network
page to open the process, the fewer the number of connection requests to open faster, and my blog page open process, total of 42 requests (33% of the site than the number of requests and more), can save 18 to connect. Also subdivided into several areas.
1, merging the domain name. Recommended that only one resource domain into other domain names under
2, merge JS. Combined under the same name of the js, you can reduce the number of network connections.
3, combined CSS. Combined under the same domain of CSS, you can reduce the number of network connections.
4, cache static resources. Little change in the static resources to the client cache can be set to reduce the request.
5, using Css Sprite. Use css sprite technique can reduce the number of requests.
Second, the download page
back pages to the server processes the request, subject to the impact of page size, page size back to the smaller, faster the sooner. I open the web page process, the total download 175.9 KB (23% of sites than the number of bytes more), can reduce 10.4 KB. This point needs to focus on adjustment. The main elements of the approach is to use compression to make, use compression techniques to reduce the element of volume, increased network speed.
Third, open the page
user's browser opens the page in the process, subject to the page content size, design and other effects. The main aspects of the following two details from the start:
1, JS position. JS on the last page, you can speed up the page opens faster.
2, image size statement. If the picture size not to define, you need to re-render the page, speed is affected.
Although the addition rate also open the page and configure the host and environmental factors themselves are related, but the most important factor is the site itself, so we have a good website to optimize the internal structure and the code are very necessary, the above three aspects are the most direct impact is the most common pages open faster, maybe some of you have done well enough, and perhaps some details have not noticed, you can begin to improve from these details.
