Cannot get the same links as my #5 and #6 competitors, seems like PBNs! Also I shy away from using PBN’s… Could you suggest a long lasting strategy? On page I’ll improve with more rich content (Already have pics, videos and 3300 words).
As already mentioned, perhaps wait a little and if nothing changes you need to build back-links and authority to help compete. See if you can see what they did differently over the past couple of weeks to get the rank improvements.
Did they add any additional content?
What back-links did they recently get?
