I have been looking at threads alot about footprints to find .EDU & .Gov links. Well, you don't have to save the footprints in notepad & word doc anymore. Just find platforms and build links whenever required.
Here is the tool: Drop My Link - Find sites to create backlinks on (I know you will bookmark this for sure )
Enter the niche and you will find loads of places where you could build links (some even allows instant approvals) for your website.
Hope this helps.
