Yes, guest posting is still effective for white hat link building if done right. You must focus on relevant, high-quality sites. Backlink articles work only if they offer real value and aren’t spammy. Find the opportunities via Google search (e.g., "write for us + niche") or use tools like Ahrefs, BuzzSumo, or manual outreach on niche blogs and forums. One think should keep in your mind which site you get backlink, that site must have visitor, high DA-PA, low spam score and related to your niche!
