I have a pretty big authority forum. I am building backlinks for it gradually. I focus mainly on long tails (e.g. 100-1000 monthly US searches). I am tracking the forum using Ahrefs. I observe this: Number of organic keywords increases (pretty) consistently Traffic is pretty unstable. Sometimes I feel great when I see that the traffic increases for a few days. Then a few days or 1-2 weeks later, traffic decreases and it returns back to the initial state (I feel frustrated). So traffic stays same (no significant improvement). Why doesn't my traffic increase? How can I solve this? Other details: I resumed building backlinks to the forum a few months ago. So I am not doing this for a long time. Rankings increase but I did not achieve top 10 on purpose for targeted keywords yet (as I said I did not do this for long) I try different link building strategies for testing. But my primary link building strategy at the moment: - Tier 1: web 2.0 blogs - Tier 2: web 2.0 blogs or cheap PBN posts I use handmade articles for Tier 1 and spun articles for Tier 2. I hope to hear some good tips to beat G safely.
