We sponsored a cultural event, got a link back from college website to our domain. To help that page gain some authority and to improve the value of that link, I started pointing links from business local listing and directories to that URL.
Is it kind of link scheme? like pointing local listing/directories to college url to pump that page up in turn helping links in that page to gain value? is it violating any search engine guidelines?
Any suggestion is welcomed. Thanks in advance.
