• Complete technical audit. The system examines every element of the website, including HTML, CSS, JavaScript, images, and multimedia resources. The scanning process simulates the behavior of search engine crawlers like Google or Bing, respecting the directives of the robots.txt file. The resulting report catalogs crawling, indexing, mobile usability, and W3C validation errors, associating each detected problem with the affected URLs and providing a step-by-step solution guide.
• On-page factors analysis. This function verifies and evaluates the individual elements of each page that influence its ranking. It checks the optimization of meta tags, titles, descriptions, headings, and keyword density. It detects duplicate or thin content, identifying pages that do not meet the quality standards required to compete in search results.
• Broken link verification. The auditor crawls all internal and external links on the site to locate those returning HTTP errors (such as 404 or 500). The tool generates a list organized by error code and link type, allowing for the systematic repair of broken links that harm visitor experience and the site's crawlability.
• Speed and Core Web Vitals audit. Through integration with the PageSpeed Insights API, this function measures page loading performance. It analyzes key metrics like Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS), generating a report that prioritizes the technical corrections needed to improve the speed score and overall site performance.
• Site structure visualization. This feature generates an interactive graphical diagram representing the internal link architecture and link juice (PageRank) distribution. The visualization helps identify orphan pages, overly deep link structures, and the hierarchy of importance among different sections, facilitating the planning of an effective internal linking strategy.
• Robots.txt and sitemap generator and editor. The tool allows creating, modifying, and validating robots.txt files and XML sitemaps directly within the interface. It offers assistance for correct syntax, allowing you to disable directories, set crawl frequencies, and manage hreflang tags. Modified files can be uploaded to the server via FTP for immediate implementation.
• Mobile usability audit. It examines the website to check its compatibility with mobile devices, detecting issues like incorrect viewports, inappropriately sized touch elements, or non-responsive content. The report details the pages that fail the mobile compatibility tests defined by Google's standards.
• Custom search and extraction with CSS selectors. This advanced function allows locating and extracting any data fragment present in the site's HTML code. Using custom CSS selectors, users can crawl structured data marks, tracking codes, specific content snippets, or any other defined element, facilitating large-scale content audits.
• Customizable crawl settings. Provides advanced controls to adjust scanner parameters according to project needs. It allows limiting the depth of analysis, restricting the crawl to specific directories, scanning sites with subdomains or password protection, executing JavaScript, and controlling the request rate to the server to avoid overloading it during the audit.
• Orphan page detection. Locates pages that exist on the site but do not receive any internal links from other pages, making them difficult for crawlers and users to discover. The function can identify these pages by comparing the sitemap or Google index with the internal link structure discovered during the crawl.

The development of WebSite Auditor began in 2008 by the company Link-Assistant. The software was created as part of a suite of SEO tools aimed at digital marketing professionals and website owners. The program is written primarily in the C++ programming language, a technical choice oriented towards guaranteeing high performance during the intensive crawling and data processing operations of large websites.
