It also includes strength indicators such as inlink rank and domain inlink rank, along with statistics related to the contextual relevance of the keyword within the analyzed domain. This makes it easy to detect whether the domain has a strong or weak presence around that keyword.

The Competition Check endpoint returns key SEO metrics for a specified domain, including total backlinks, referring domains, authority scores, inlink rank, and counts of .edu and .gov links. This data helps assess the domain's strength and relevance for a given keyword.
The response data includes fields such as total_backlinks, referring_domains, edu_links, gov_links, authority_score, inlink_rank, and contextual_relevance, providing a comprehensive overview of the domain's SEO performance.
The response data is structured in a JSON format, with each key representing a specific metric. For example, you might see fields like "total_backlinks" and "authority_score" clearly labeled, making it easy to parse and analyze.
The Competition Check endpoint accepts parameters such as the domain name and the keyword for analysis. Users can customize their requests by specifying these parameters to receive tailored SEO metrics relevant to their needs.
Typical use cases include evaluating a competitor's SEO strength, identifying backlink opportunities, and assessing the relevance of a domain for specific keywords, which can inform strategic marketing decisions.
The data is sourced from various SEO tools and databases that aggregate backlink profiles, domain authority metrics, and contextual relevance indicators. This ensures a comprehensive view of the domain's SEO standing.
Users can analyze the returned metrics to identify strengths and weaknesses in their SEO strategy. For example, high authority scores and a strong backlink profile indicate a competitive domain, while low metrics may suggest areas for improvement.
Data accuracy is maintained through regular updates and quality checks, ensuring that the metrics reflect the current state of the domain's SEO performance and backlink profile.
Users can expect to see a range of backlink counts, authority scores, and inlink ranks that vary widely based on the domain's SEO strength. Patterns may indicate strong or weak keyword relevance based on contextual metrics.
