What is a high-DA backlink?
A high-DA backlink comes from a domain with a high authority score (a third-party metric estimating ranking strength). Higher-authority domains tend to pass more PageRank — but DA is a proxy, not a guarantee.
Why relevance beats raw DA
A high-DA link from an unrelated or spammy page is worth far less than a mid-DA link from a relevant site. Always weigh relevance first, then authority.
