2.4 Trade Wind Algorithm - Controlling Page Turning Induction

In May 2019, Baidu search released a trade wind algorithm to combat the behavior of websites using page-turning keys to induce users.

The trade wind algorithm is mainly for the following situations:

When the user clicks the page key, they will automatically jump to other channel pages of the website (such as catalog pages, off-site advertising pages, etc.).

Question example 15: On the mobile terminal, the user clicks "Next" to directly jump to the channel directory page on the site


Problem example 16: On the PC side, the user clicks "Next" to directly jump to the channel directory page on the site


For such issues, we recommend:

1. Do not place false page turning keys.If you want to get more users to browse and click, you can recommend relevant high-quality content for users after the text ends to attract users to click.

2. Respect the user's browsing experience and avoid deliberately splitting a short article into multiple pages.

For more information on the trade wind algorithm, please refer to:

2019.5.22 Put an end to page-turning induced behavior, Baidu search trade wind algorithm will be launched soon
