Which software to build the backlinks automatically and fast?

Someone send me a website： thehearup.com
and it has https://sem3.hoocs.cn/analytics/organic/positions/?db=us&device=desktop&q=thehearup.com&searchType=domain&date=20210820 traffic. But the major keywords that contribute to the traffic look no sense.
Keyword search volume
https://sem3.hoocs.cn/analytics/keywordoverview/?db=us&device=0&q=msum%20d2l 18,100
https://sem3.hoocs.cn/analytics/keywordoverview/?db=us&device=0&q=vipleague 90,500

https://sem3.hoocs.cn/analytics/keywordoverview/?db=us&q=ana%20nello 2,900

Are these search volumes real? Or does the blogger use the software to create the search volume?

If the search volume is real, how to find these keywords?

the title and content of your post are not even remotely related. I don't know what you want to be honest...
