购买反向链接安全吗？
如果您知道链接的站点，那么购买反向链接是安全的。例如，我知道网站所有者已经从forbes，inc等处购买了链接（通过这些平台上的自由撰稿人），并且他们做得非常好。  
您还可以使用链接管理之类的平台从许多站点安全地购买反向链接。
most 反向链接 monitoring tools have detect your 反向链接s by regularly crawling the web and 建造 a 反向链接 database to check your links from. they aren’t perfect and often big enough to detect all links as you build them. even google’s own search console shows a small amount of links you receive. 您 should either give enough time for your 反向链接s to get indexed or use a better link checker tool like ahrefs that probably has the best &最大的实时反向链接数据库。
