要激活网站再营销推广活动，需要达到多少网站访问量？

To activate a website retargeting campaign on LinkedIn, your website must have received at least 300 unique visitors in the last 30 days. This minimum threshold ensures a sufficient audience size for effective retargeting and allows LinkedIn's algorithms to optimize campaign delivery. Fewer visitors (e.g., 100) would likely result in too small an audience for meaningful retargeting, while higher numbers (e.g., 500 or 900) are not the minimum requirement. There is a specific minimum requirement, so "no minimum requirement" is incorrect.
