I imagine similar methods have been shared, but I just saw in a MOZCON video and thought it was brilliant: Step 1. Find niche related blogs that have expired a couple years ago through whatever site you like. Don't know where to look start at expireddomains.net Step 2. Throw the URL in the waybackmachine at archive.org to grab the post. Step 3. Test post in google to make sure they are not PLR's or something Step 4. Post those bitches, spin them and submit, whatever you want to do its all good original content related to your niche!
