Any body know creating High quality Backlinks with XSS hacking

I was shocked after seeing the webiste backlink profie.
I open 100s of link target sites to find the backlink of that website.
I didn't find any backlinks of that site on those sites all the sites are linked directly to the home page.

finally, I found after researching for hours.

all the target websites have the search box, YES.
HE IS CREATING BACKLINKS WITH THE HELP OF JAVASCRIP INJECTING THROUGH THE SEARCH BOX. [XSS HACKING]

if anybody knows this process please help me to find the right solution how to create the backlinks.

thanks.

As far i know about XSS and sql injection hacking, it's only temporary front end(browser) process then it's not permanent process that script hosted in server, if u place javascript to form for GET or POST request and u got that script run then it's a xss,
But idk if the xss vuln can be indexed or cached by google

Yes you are right, they are temporary. but after creating backlinks through query strings

i mean abc.com?s=http://www.oursite.com then if this creating link on that searchpage.

then we should create backlink for this abc.com?s=http://www.oursite.com then google accept it as backlink.

The website using xss backlin process ishttps://www.pluginsaddonsextensions.com/

We can’t talk about hacking in here afaik.
