Each endpoint returns specific SEO metrics. The "Get Domain Authority" endpoint provides Domain Authority, PageRank, Global Rank, and Spam Score. The "Get Backlink Profile" endpoint returns total backlinks, unique referring domains, and top linking URLs. The "Get Referring Domains" endpoint lists external domains linking to the target, while the "Compare Domains" endpoint offers a side-by-side comparison of multiple domains' authority metrics.
Key fields vary by endpoint. For "Get Domain Authority," fields include domain, pageRank, rank, domainAuthority, and spamScore. The "Get Backlink Profile" includes totalBacklinks, referringDomainsCount, and topBacklinks. The "Get Referring Domains" features totalFound and referringDomains, while "Compare Domains" provides domains and a leaderboard with rank, domain, pageRank, domainAuthority, and spamScore.
Response data is structured in JSON format. Each endpoint returns an object containing relevant fields. For example, "Get Domain Authority" returns a single object with metrics, while "Get Backlink Profile" returns an object with total backlinks and an array of top linking URLs. This structure allows for easy parsing and integration into applications.
The "Get Domain Authority" endpoint provides authority scores and spam metrics. The "Get Backlink Profile" offers insights into backlinks and referring domains. The "Get Referring Domains" endpoint lists unique domains linking to the target, and the "Compare Domains" endpoint allows users to analyze multiple domains' authority metrics side by side, facilitating competitive analysis.
Data is sourced from reputable platforms: Domain Authority and Spam Score are derived from Moz, PageRank and Global Rank from Open PageRank, and backlinks and referring domains from Common Crawl. This combination ensures comprehensive and reliable SEO insights.
Users can customize requests by specifying the target domain in the endpoint parameters. For example, when using "Get Domain Authority," simply provide the desired domain as a parameter. For "Compare Domains," users can input 2 to 5 domains for comparison, tailoring the output to their specific analysis needs.
Typical use cases include SEO audits, competitor analysis, and client reporting. Developers can integrate the API into SEO tools, while agencies can automate research and generate insights for clients. Freelancers may use it for quick assessments of domain authority and backlink profiles.
Users can leverage the returned data to assess domain credibility, identify backlink opportunities, and compare competitors. For instance, the Domain Authority score helps gauge a site's SEO strength, while the backlink profile reveals potential link-building strategies. This data can inform SEO strategies and enhance digital marketing efforts.
