Keyword ideas, domain overview, organic competitors and backlinks for SEO research.
Each endpoint returns specific SEO-related data. The Keyword Ideas endpoint provides keyword suggestions with metrics like search volume and competition. The Domain Overview endpoint offers insights into a domain's traffic and authority. The Organic Competitors endpoint lists domains competing for similar keywords, while the Backlinks endpoint details referring pages and their metrics.
Key fields vary by endpoint. For Keyword Ideas, fields include "phrase," "volume," "cpc," and "difficulty." The Domain Overview includes "authority_score," "number_of_backlinks," and "search_traffic." Organic Competitors features "domain," "competition_level," and "traffic," while Backlinks includes "source_url," "target_url," and "page_ascore."
Each endpoint accepts specific parameters. The Keyword Ideas endpoint uses a seed keyword and an offset (0-90) to paginate results. The Domain Overview requires a domain name. The Organic Competitors and Backlinks endpoints also use a domain name and an offset for pagination, allowing users to customize their data requests effectively.
Response data is structured in JSON format. Each response includes a "success" status, a "requestId," and an "items" array containing the relevant data. For example, the Keyword Ideas response lists keywords with associated metrics, while the Domain Overview presents a summary of traffic and authority metrics in a structured format.
The data is sourced from various SEO tools and databases that track keyword performance, domain authority, and backlink profiles. This includes search engine data, web crawlers, and user-generated content, ensuring a comprehensive view of SEO metrics.
Typical use cases include keyword research for content creation, competitive analysis to identify market positioning, and backlink analysis to enhance SEO strategies. Users can leverage this data to optimize their websites, improve search rankings, and identify growth opportunities.
Users can analyze the returned data to identify high-potential keywords, assess domain authority, and understand competitive landscapes. For instance, by examining keyword difficulty and search volume, users can prioritize content topics. Backlink data helps in strategizing link-building efforts.
If results are partial or empty, users should check their input parameters for accuracy. For example, using a less common seed keyword may yield fewer results. Adjusting the offset or trying different keywords can help retrieve more comprehensive data.
