This is pretty interesting as I was skeptical it would have any noticeable effect... I had done an AMR blast a few weeks ago to my money site for a 1k exact keyword. That and some other things such as SB blasts had me stuck for a week or more near the top of 4th page. Actually after the initial AMR blast I think I crept to bottom of 3rd then soon after got stuck at around 3rd from top on 4th which I didn't seem to budge even though I had been SB blasting round the clock. So yesterday I thought I'd try another AMR blast but to the 1st AMR tier making it a 2nd AMR tier. I took all the livelinks from the 1st blast and spintax'd them into the new article and blasted away. I did that yesterday not expecting much but today to my pleasant surprise I see I've moved from around 3 from top on 4th to three up from the bottom on the 3rd. So a 6 slot jump which is I think is sweet considering I was having trouble getting any movement before. I want to keep testing this stacking principle and see how much juice I can get out of doing this before it becomes diminishing returns. Maybe I'll do a garbage auto spin today with the same article and reblast to 2nd tier. One good thing I was thinking about the linking structure is due to the spintax the linking is gonna be random of which article leads to which so I am guessing that produces some sort of diversity in the pattern to aid in the juice.
