Baidu input "website optimization" is the overwhelming number of Web site optimization related articles, how to improve the site rankings, how to improve the site traffic, today, Beijing website optimization to talk about is not these, but how to optimize the performance of the site?

Why do you want to optimize your site performance? There are several reasons:

1 Save resources, server, network resources;

2 eliminate or reduce the bottleneck of the system;

3 Improve the user experience

Most companies make optimizations from the previous two, while the "enhance user experience" is from the point of view of the user (site visitors), but rarely to a very important level.

In addition, perhaps there are also the factors of the technology, in order to optimize the optimization, of course, this is not advisable.

Establish effective metrics

An effective method of optimization is to have effective metrics. A user visits a website, from submitting a request to getting a response, seeing the page completely, each link in the middle should ensure proper optimization. Otherwise, if the back end has been "perfect" optimization, single user requested page has http://www.tm224.com.cn many pictures, is also a bad thing. There are likely to be large deviations before end-to-end measurement data collection is established.

The common question is, do you know what line users are using to access their site? What kind of ADSL line, how many still use dial-up Internet? How many users are there in Internet cafes? How many are mobile device users? ... If such data collection is deficient, it is difficult to make effective performance metrics.

Some mistaken understanding of optimization

Server pressure down = User Access speed This is the most common kind of optimization attitude. Technical personnel to their own web site exhausted a variety of optimization means, server pressure finally reduced, single users will be really satisfied? Not。 But it is futile to have never seen the end user's access habits and network connectivity as an objective factor.

Front-End optimization is not as important as back-end optimization is still not deserved, and most designers still turn a blind eye to performance problems, to get a 1M-size activity page for them, the image design is gorgeous may be the most important. For the increasingly need for multimedia, rich media performance of the page, front-end optimization is in fact the most important. Both hands are hard to grasp. Users visit the laborious page, again gorgeous is rubbish.

Save PV = reduce PV to KPI-oriented Web companies, PageView may be a lot of people's jobs, easy to den. But for KPI makers, at least have the PV to identify the false boom (unless they are also members of a cheating gang). Unnecessary PV can save on savings, and savings in bandwidth resources are left to more valuable applications.

To do optimization as a project to do some of the sites will have "a project to a certain block to do an optimization" thing. Optimization should be a long-term, ongoing thing, if simply as a project to do, may be a wave of warm past no one.
