• Robots Directive Identification. Examines the meta robots tags of each URL to determine if a page is blocked from indexing (noindex) or link following (nofollow). Provides a clear listing of all applied directives.
• Redirect Monitoring. Logs and classifies all HTTP redirects, both temporary (302) and permanent (301). Helps detect excessively long redirect chains that can dilute page authority.
• Title and Meta Description Analysis. Reviews each page to locate duplicate, missing, or overly long titles. Delivers a report with current values to facilitate optimization.
• Duplicate Content Detection. Compares text fragments and content hashes between pages to flag potential internal duplicates. Allows managing the risk of keyword cannibalization.
• HTTP Header Verification. Analyzes cache headers (Cache-Control, ETag), Gzip or Brotli compression, and the HTTPS protocol. Identifies mixed content (HTTP/HTTPS) that could compromise security.
• Structured Data Validation. Scans the code for JSON-LD and Schema.org markup. Checks for required properties and notifies syntax errors that prevent the generation of rich snippets.
• Hreflang Tag Analysis. Reviews hreflang implementation for multilingual sites. Verifies that language and region codes are valid and that correct reciprocal relationships exist between pages.
• Robots.txt and XML Sitemap Inspection. Fetches and analyzes the content of robots.txt. Crawls XML sitemaps, even nested ones, and reports the included URLs, identifying those blocked by robots.txt.
• Link Graph Visualization. Generates an interactive force-directed graph representing the site's internal link structure. Shows how pages connect and helps identify isolated nodes or those with excessive depth.
• URL Depth Analysis. Calculates the click distance from the homepage to each crawled URL. Highlights important pages that are more than three clicks away, which may hinder crawling.
• Security Header Check. Inspects the presence and value of headers like HSTS (Strict-Transport-Security) or Content-Security-Policy. Evaluates if the server configuration follows recommended security practices.
• PDF Report Export. Compiles all crawl findings into a structured PDF document. Includes summary charts and detailed lists of issues for presentation in professional reports.

Development of Seodisias began in 2020. The application is written in the C# programming language and uses .NET to run on Windows systems. The developers focus on providing a desktop tool that performs complex analyses directly on the user's machine, avoiding reliance on cloud services with page limits.
