This is interesting, i have 2 relatively new client sites on a different niche, one is on a food niche (site A) and one is on a health niche (site B). I manage to rank around 15+ keywords on the first page for Site B in just 2+ month, the KC is easy and medium. While on site A, KC is easy-medium and it's been almost 5 months and i'm still stuck on page 2.
My link buiilding strategy on both sites are pretty much the same, except on site B i don't use PBN at all, just a couple of 301 redirect from an expired domains on the same niche. While on site A i drip 15 links/month PBN post the last 3 month and still stuck at page 2.
From your experience, how much time did it take to break through from page 2 to page 1?
