Checkbot vs WebSite Auditor

Checkbot is a Chrome extension for auditing websites for SEO, speed, and security issues. Its checks can flag broken links, duplicate content, invalid HTML, and insecure forms. The crawler can examine hundreds of pages in minutes, while site structure information shows linked pages, image, JavaScript and CSS files, non-indexable pages, and redirects. It can also reach staging and local development sites, password-protected pages, and private networks. Crawling and other functions run locally on the user's machine; Checkbot says it does not operate as a web service. The free Basic plan allows 100 URLs per crawl, unlimited crawls and sites, with ads. Professional costs $10 a year, billed $120 per year, or $15 a month; it raises the crawl limit to 10,000 URLs and adds localhost crawling, PDF reports, CSV and bulk export, and HTTP Auth support. The extension runs on Windows, macOS, Chrome OS, and Linux, but does not execute JavaScript during crawls. Usage analytics and crash reports are opt-in.

WebSite Auditor is software for technical and on-page SEO auditing and website optimization. It crawls site architecture and checks HTTP status codes, broken links, HTML errors, titles, meta descriptions, and link factors. Its content module provides page-specific recommendations, keyword-density guidance, and HTML-element analysis; pages can also be compared with 10 top-ranking competitors. The software generates Google-friendly XML sitemaps, can upload them through FTP and submit them to Google, Yahoo!, Bing, and Ask, and creates and manages robots.txt files via FTP. It supports 750 search engines and UTF-8 content in any language. Google Analytics traffic data and Search Console metrics can be added to projects, with clicks, impressions, CTR, and average rank available for export. The free license covers 500 URLs and one project, with no paid report exports. Professional costs $149 a year; Enterprise costs $359 a year. It runs on Linux, macOS, and Windows. The maker offers a seven-day trial of paid SEO PowerSuite features when requested from support.
