How can the domain name and program be changed after the website is completed without being demoted?

　　 1： How long is the website suitable for modification?

The small editor suggested that it should be revised at most once in two years and submitted after being revised and improved. Of course, these two years refer to the change of domain name, not the change of program! If the program is changed, as long as the old program is not really eliminated by the industry, or cannot seriously meet the current needs, we do not recommend making changes.

　　 2： Is there any big bug in the new domain name program?

Many webmasters like to buy some old domain names that have been registered for a long time to build websites, but many people have suffered a "dark loss". For example, new domain names are blacklisted by search engines because of illegal information. In this case, if you change the domain name to a new one, you will surely die. So webmaster must pay attention to query before buying domain names. The query method can be to enter "www.domain name" and "top-level domain name" in Baidu, and replace Chinese characters with your domain name.

In terms of programs, I saw too many "junk" programs, which have gorgeous functions, but are very bad in terms of optimization. What we usually recommend is not to select partial programs, but rather popular programs, not to mention that general programs will affect optimization. There is no such thing. At the same time, not all websites need to be developed independently. Let me tell you a little secret. Maybe the program you bought with tens of thousands of dollars is not as good as the website made with a "free version" program.

　　 3： URL path and website revision

Relatively speaking, domain name modification is the simplest. No matter the path, just change the domain name, and then make changes and submit. Basically, there are no major problems. However, when the program is revised, the path will be changed, for example, the ASP program will become a PHP program.

I have solved such problems for many customers here. What preventive measures do you need? First: 301 redirection can be done for those who can do 301 redirection. Article 2: Do not delete if 301 redirection is not available. Third, it is also very important: try not to repeat too much data information of old and new sites. If it is unavoidable, such as product duplication, it should be less. If it is repeated too much, it needs to be reprocessed.

Of course, according to the complexity of the website, there are some other options for the website replacement program. The above is a general type, which is also the most suitable way for small and medium-sized websites, not for large websites.

　　 4： Optimize the new program before going online

Don't mention that after my website goes online, I will slowly find problems, just "click" what is wrong! No good website does this: please solve the optimization problem before the new program goes online. For example, after some programs go online, there will be a problem of multiple links to content, or the number of pages turned is very short, but the number is very large and so on.

Only by doing this can the website achieve a real smooth transition, otherwise the probability of weight reduction will be greatly increased. Of course, any website may change its domain name or program, even if it does well, to reduce its rights. No one can do this 100%. So don't go to such extremes unless you have to!
