Buy backlinks only from strong, trustworthy sites. Look for Domain Rating (DR) 50+, URL Rating (UR) 20–40+, Domain Authority (DA) 40+ (or 20+ in niche fields), Trust Flow 20+, and Spam Score under 5%. Avoid sites with Spam Score over 15%.
Your link should sit naturally inside real content - not in footers or sidebars. Relevance matters more than size: a smaller site in your niche is better than a big unrelated one.Use varied anchor text - your brand name, phrases like “learn more here”, or short descriptions. Skip cheap links - they often risk penalties.
If your traffic dropped, check the site’s IP and blacklist status - just to be safe.
