A great way to strengthen your AMR links is with more AMR links. Develop a list of the crappiest 50 or so, with no editorial management whatsoever and low PR, that are based on wordpress. Prepare an AMR campaign where the spin has a random 20 links in it, to the last campaign you just ran.
Make sure you get a report of the successful AMR postings and verify it with scrapebox to make sure your link actually exist on your page. Then use that list to build the random 20 links. In case it isn't obvious, set up the random 20 links in spintax (insert 200 or so successful post URLs, batched into 10 random groups of 20 links).
