WebsiteSEOChecker.pro is an SEO analysis platform that helps website owners, marketers, agencies, and developers assess domain strength and identify opportunities to improve search performance. Its tools use the official Moz API for Domain Authority and Page Authority scores, alongside additional verified data sources for other metrics. Users can check up to three domains daily without an account, while free registration unlocks account features and access to bulk analysis.

For each domain, the platform can report Spam Score, an authority score, backlinks and their dofollow/nofollow distribution, domain age, and estimated monthly search traffic. Its bot simulator shows how Googlebot may view a website and helps identify technical issues involving meta tags, canonical URLs, hreflang, crawlability, and robots.txt. Other offerings include backlink analysis, domain research, competitor comparisons, and a REST API for integrating DA/PA checks into custom tools and workflows. Registered users can save analysis history, export results to CSV, and track SEO progress over time. WebsiteSEOChecker presents its services as fast, accessible resources for evaluating domains and supporting SEO research.
