No, not all backlinks are made equal. Backlinks will vary in quality depending on various factors, and the higher quality the backlink is, the more powerful it will be for your Amazon SEO. Low-quality backlinks refer to links from spammy sites or sites with very small domain authority (DA). Low-quality backlinks can do more harm than good, and backlinks from spammy sites should always be avoided. If you have low-quality backlinks pointing to your product pages, you might want to consider disavowing them.
On the opposite end are high-quality backlinks. These backlinks are the ones that come from trusted websites and publications. For example, a backlink from the New York Times will be significantly more powerful than a backlink from an unknown travel blogger. But it should be noted that getting backlinks from major publications can be extremely difficult – instead, try and focus on mid-sized websites with DA’s around 30-40. These backlinks are still powerful, but are easier to get.
