How can we minimize the loss of large-scale website revisions?

How can we minimize the loss of large-scale website revisions? For large websites, traffic starts from, but any website has to be revised because of business needs or system upgrades. How can we correct the revision to minimize the loss of the website? This is especially true for large websites. In this article, he Guijiang provides several typical revisions and guidance.

I. Template change revision

In the website revision process, template change is the most common revision. this revision is normal without any risks, but there are still some website problems, so what is the situation?

First case: there are many optimization problems in the website template itself, which leads to poor overall website optimization. you must know that the search engine looks at the website front-end. if the previous optimization is not as good as the previous one, rankings naturally go backward.

The second case: the layout of the internal chain has a problem. Simply put, a page generates a ranking because the whole site gives it enough weight for the internal chain, but in the new template, if this weight disappears, will the ranking be generated?

The revision of the template is the easiest, but for large websites, the more complicated the template is, the more risks it faces. do not place templates that are not well-handled by SEO on the program, once it is put up, do not modify it! In addition, after the template is changed, 404 monitoring is required, which can be viewed using the Baidu webmaster tool or LOG.

II. revision of the change procedure

Some websites were built very early. some time ago, a website was used for SEO diagnosis. The website has been built for more than a decade, but it is still the most basic ASP, and even dynamic links, the system features are also very weak, and basic topic title settings are not supported. Therefore, you need to make a new version of the program (his website includes more than 0.3 million) while performing SEO diagnosis ).

For his revision, it was an ASP program. how should I change it to a PHP program? We recommend that you directly set up a PHP program on the current site and redirect all the column pages to the new column page 301. In addition, the previous content cannot be deleted, and the previous content pages cannot be stored in new programs. This Webmaster used to collect data from the entire site to the PHP site, which is totally wrong. even if it can be 301, it is still not suitable! Do you know?

The above is a form of revision, which is the same type of language, and may cause a large number of directory and structure conflicts that cannot be avoided at all. how can this be done? You can add the old site to the new subdomain name, and then set it to 301! This kind of loss is also the biggest. it is important to submit the website revision rules on the webmaster platform!

III. system upgrade revision

In addition to the template change, the system upgrade is the most widely used by webmasters. for example, adding a module and creating a new function are all system upgrades. However, such upgrades will cause problems for some websites.

At the end of 2015, I diagnosed a website, and then the website was upgraded to a system. as a result, the number of records recorded in the website increased by 2 million in a week! Why? The new upgrade program will overwrite the robots.txt behind the optimization! This is a very serious problem. The indexing of million junk pages has a great impact on the website!

To do this, we should remember that, no matter how the website is upgraded, if there is a coverage upgrade, we must check what can be covered, which are not covered.

There are also some system upgrades, such as the addition of modules, feature development will generate some new pages, such upgrades should be evaluated in advance: whether the new page meets the search engine rules, whether the new page has enough information to improve the page, to meet users' needs, is not just a framework.

In addition, the revision of the system upgrade should pay close attention to the frequency of crawling by search engines, as well as whether the crawling test can be quickly connected, and whether a series of problems such as slow crawling will occur due to the large page size.

Finally, there is a very important note: The larger the website traffic, the more data is included, the more attention should be paid to the revision principle: as long as there is no problem, it will not be changed, but only make necessary changes to the problem, other modifications will be made when the website development bottleneck is reached! Why is the ranking worse for some websites with improved performance? It was because the changes were too frequent, but they did not realize this problem!
