Hi I have a medium competitive keyword in the second page for around 5 months, but in the fact all the backlinks I have got in last months is very weak. SERP is #13 to #17 in the last 5 months. Keyword difficulty in Moz is 33. Now I have the chance to get 3 good backlinks (I plan to get them at intervals, 1 link every 3 weeks maybe to look natural). First : DA 21 / PA 30 Same niche website. Second : DA 28 / PA 35 Not same niche website but content around the link related to my niche. Third : DA 35 / PA 30 Not same niche website but content around the link related to my niche Do you think these 3 backlinks is enough to see movement ?
