Easy to cause sandbox effect SEO details [stationmaster must see]_ website operation

Believe that Google's sandbox (Sandbox) mechanism has a more in-depth understanding. Because I have written several articles about the sandbox mechanism before. Related articles such as:
The effect of 1.Google sandbox sand box
2.seo,google sand box and the right to drop
For the sandbox of some of the more basic things, do not understand the above two articles can be seen.
Before, we have said. A website online, 90% will encounter Google sandbox. The reason for this sandbox is that it has been mentioned in the first two articles. This is not repeated here.
According to the SEO industry experience, not that only new sites will encounter the sandbox. Even if the site is running for several years, if some SEO factors are not handled well, it will trigger the sandbox mechanism. Let the website sink into the sandbox.
For example:
1. External links increased too quickly;
External links are growing too fast to be used by search engines as unconventional tools. This may trigger Google's sandbox mechanism, causing the search engine's attention.
2. The anchor text of the external link is too single;
External link text should try to use a number of different anchor text, but each anchor text should be related to the site theme. For example, you can use: SEO, hangzhou seo, seo, hangzhou search engine optimization, search engine optimization and other anchor text.
3. A sudden increase in content;
The frequency of site content updates, it is best to maintain consistency. For example, every day is updated with 10 articles. If a sudden increase of 100 more than before, it will also cause the search engine's attention. The trigger sandbox mechanism is just one, and there should be other aspects of the impact.
Basically, the important details that can trigger the sandbox mechanism are the above points.
If you accidentally get the site into the sandbox, you don't have to worry too much. As long as you keep updating, you can keep expanding the quality of external links. The only effect is that it will waste a lot of time.
