As a webmaster no one does not want their own site is very good, or to spell the goal of the Site keyword optimization, or the number of long tail to fight the site, or the appearance of the site, or spell the site's function, we have been working hard to make their own site better, more valuable, so we desperately for the site to do addition calculation. As time passes by, the site is becoming more and more difficult to optimize, even ranking down, or may be Baidu down right. At this stage, I think we should stop the pace of optimization, back to check the details of the site, when you carefully to diagnose every item of the site, I believe you will find your site because your optimization is too drastic, because you have been adding things to your site, so there are too many bloated redundant useless script, so, It is necessary for us to reduce the pressure on the site, do the appropriate subtraction operations, so that the site light.

First, for the mainstream CMS to do page optimization

A brief analysis: I believe many webmaster in the station, will be for their own cost reduction and choose Open Source CMS (Dedecms, phpcms or Imperial cms, etc.) to make changes or two development. For the major mainstream CMS, the function is quite strong, such as the current PHPCMS V9 have real estate, Yellow Pages and video modules, so these mainstream CMS can be said to be "all-encompassing."

Remark: In fact, we are in the actual use of open source mainstream CMS station, there is a considerable part of the function do not need, so it is necessary in the site before the site on the page to label optimization, code reduction and so on.

Optimized strategy: 1. Remove garbage code without mercy. I simply read the garbage code as useless code in the page, and the code is deleted, the site has no impact, there will be no negative effects. For example: Open source CMS with its own advertising code, like Dedecms's own Sogou ads, I last found a customer is really high, the site 9 months of time, Baidu Weight 3 is also good, but the site is also placed in the dedecms of the Sogou advertising code, I really have to admire. In addition to this, including web production software tools such as the default generated by the useless code, including the meaning of the words of the word, space, code and code blank between the blank and unwanted default properties.

2. Remove unnecessary modules without any mercy. In each major mainstream CMS has its own comment function, message function, share plug-in function, comment functions like Dedecms and novel serial function, DZ forum plug-ins are many, for these redundant modules or a lot of plug-ins, do not have everything to your website, Don't put it on your website because you don't need it. I used to learn to do the station of a young guy, just met him when he show me his website, he used is a local forum dzx2.5 construction, I carefully checked the next, all can install Plug-ins he installed, I could not help but ask him these plug-ins on the site when he actually came to the sentence: " Since it is the official to the plug-in, we have to respond, installed after the support of others, so I have all installed ", after listening to, I feel very silent, unexpectedly will use this way to thank the developers. In fact, I think for a plug-in used in the right place, with the use of live to reflect the value of the plug-in itself. Besides, if you install so many useless modules or plug-ins on your website, it will lead to a great reduction in the speed of Web access and therefore reduce the user experience, but also make the search engine crawl the site very hard, I think it is unreasonable. So it must be no polite to remove the redundant modules and plug-ins.

Second, to all types of Web site to do page optimization

In the 1th, we put forward to mainstream CMS page optimization analysis, comment and optimization strategy, the 2nd to say is included in addition to the mainstream CMS site and the mainstream of the Web site to make the optimization of the page, mainly from the following aspects to implement.

1, the optimization of CSS. Here the main optimization is the way to optimize CSS calls, there are a lot of webmaster do station, may go to A5 trading, pig eight precepts and other Granville guest on the issue of the task, please others to help imitation station, and others will be the site of the purpose of the site of all the CSS is taken over, whether or not superfluous, anyway, as long as the function is complete, the style is OK, Finish the job. So webmasters if you have the same experience, you may wish to check your site's CSS, for multiple files of the merged CSS merge, delete the deletion, there is the same CSS file, if there are redundant CSS code also delete processing, to minimize the garbage code, while your CSS code compression processing , you can increase the speed of Web site access.

2, the same to JS (JavaScript) that is, flash to optimize. For Ajax asynchronous calls or JS dynamically generated pages, so far, spiders can not be resolved to the site to play a lot of special effects and use of flash, if it is really not necessary, you can use Div to replace, as far as possible with flash or not. That is to say JS and Flash and the IFRAME framework is actually very unfriendly to search engines, so we must do a good job of optimizing processing. At the same time also to the JS file compression operation.

3. Delete Redundant attachments. When we update the content, may upload some attachments, including pictures, compressed packets, and so on, sometimes there will be redundant attachments, so carefully check these redundant attachments, if not necessary, please delete these redundant attachments.

The above we explained the mainstream CMS production site or other sites, especially for people to copy the site, do some of the site subtraction operations, so that the site's pages more in line with search engines, more conducive to access, but also conducive to further optimization of the site, I hope to webmaster friends have some help.
