Each endpoint returns specific SEO-related data: the "Get Domain Authority" endpoint provides metrics like Domain Authority and Spam Score; "Get Backlink Profile" offers total backlinks and unique referring domains; "Get Referring Domains" lists external domains linking to the target; and "Compare Domains" delivers a side-by-side comparison of multiple domains' authority metrics.
Key fields include "domain," "domainAuthority," "spamScore," "totalBacklinks," and "referringDomainsCount" for the respective endpoints. For example, "Get Backlink Profile" includes "topBacklinks" with URLs and metadata, while "Compare Domains" features "leaderboard" with ranks and scores for each domain.
Response data is structured in JSON format, with each endpoint returning a specific object. For instance, "Get Backlink Profile" returns an object containing total backlinks and an array of "topBacklinks," while "Compare Domains" returns a leaderboard array detailing the rank and metrics of each domain.
Each endpoint provides distinct information: "Get Domain Authority" offers authority scores; "Get Backlink Profile" details backlinks and referring domains; "Get Referring Domains" lists unique domains linking to the target; and "Compare Domains" presents comparative metrics for multiple domains.
Data is sourced from reputable platforms: Domain Authority and Spam Score are from Moz, PageRank and Global Rank come from Open PageRank, and backlinks and referring domains are managed by Common Crawl, ensuring a comprehensive and reliable data set.
Users can customize requests by specifying the target domain in the endpoint parameters. For example, when using "Get Domain Authority," simply input the desired domain to retrieve its specific metrics. Each endpoint accepts a single domain or multiple domains for comparison.
Typical use cases include SEO audits, competitor analysis, and client reporting. Developers can integrate the API into tools for real-time backlink analysis, while agencies can automate research and generate insights for client presentations using the comparative data.
Users can leverage the returned data for strategic decision-making. For instance, the "Get Backlink Profile" can identify strong linking domains for outreach, while "Compare Domains" helps visualize competitive positioning, aiding in SEO strategy formulation and client pitches.
