I'm wondering whether niche relevance is really that important for backlink exchanges. If niche relevance is essential, wouldn't that mean we'd mostly need to collaborate with competitors or businesses in the same industry? The number of websites that are both niche-relevant and open to backlink exchanges seems quite limited. So, how important is niche relevance in practice, and is it okay to build backlinks from websites that aren't in the exact same niche but are still high-quality and relevant in a broader sense?
