backlink_summary

Tool of DomainKits

SEO backlink analysis powered by DataForSEO. Use when: (1) user explicitly requests SEO analysis or domain valuation, (2) evaluating expiring/deleted domains before acquisition. Do NOT call for general browsing or availability checks. Key fields and interpretation: - rank: Domain authority on a 0-1000 logarithmic scale (based on PageRank). Each point higher is exponentially harder. Reference points: apple.com/iphone ~848, stackoverflow.com ~740, forbes.com ~650, ahrefs.com/blog ~395. - backlinks_spam_score: Spam score of all incoming backlinks (0-100). 0-30 low, 31-60 medium (warrants investigation), 61-100 high (significant risk). - target_spam_score: Spam score of the domain itself (0-100). Same thresholds. - Always calculate key ratios from the raw data: backlinks per referring domain (total_backlinks / referring_main_domains — high ratio like 500+ means a few domains contribute most links), referring IPs vs referring domains (low ratio suggests shared infrastructure, potential PBN signal), broken backlinks as percentage of total (high percentage means decaying link profile), follow vs nofollow distribution from referring_links_attributes (near 100% follow is unusual for a natural profile). - referring_links_platform_types: If message-boards or web2.0 platforms dominate, this can indicate low-quality link building. - referring_links_tld: Note presence or absence of .edu/.gov links. - new vs lost backlinks and referring domains indicate whether the profile is growing or shrinking. Caveat — passive referrals on aged domains: Some low-quality or scraper sites automatically link to old domains (abandoned blogrolls, scraped content, auto-generated pages). A small amount of this noise is normal for aged domains — Google's algorithms can identify and ignore these junk links, so a few low-quality referrals should not be treated as a risk signal. However, a large volume of junk referrals is a different story — it may indicate the domain was used for black-hat SEO, link schemes, or was targeted by malicious backlink attacks. As with everything, degree matters: a handful of scraper sites is background noise; thousands of them is a red flag. Present facts and data. Do NOT make buy/don't-buy judgments — let the user interpret the signals.
