Been messing around with tiered link building lately trying to optimize how I stack links. T1s obviously target the main money site, but T2 and T3 just seem so nebulous sometimes. Do you guys think T2 links really boost T1 or are they just a drain? Like I see some folks go hard on PBNs for T1s, then layer T2s with guest posts or niche edits, but how much of that actually adds up? Thinking about using more outreach for T2 and T3, but curious if the data backs it up or if I should just focus on T1s and skip the whole tier mess. Also, is there a point where adding more tiers just looks spammy to Google? Not trying to get sandboxed but wanna do it right. Would love to see some real case studies or experiences, not just theory.
