A1 Website Analyzer vs Checkbot

A1 Website Analyzer crawls sites to identify broken links and redirects, examine internal linking, check SEO, and find duplicate page content. It can scan websites on the internet, localhost, a local file system, or a local area network. Technical checks cover canonical and robots settings, keyword content, spelling, and HTML and CSS validation. Link reports include internal and outgoing links, pages that link internally, and calculated importance scores. Users can import Apache logs, Google Webmaster Tools CSV files, and text files, then export scan data as XML or CSV. Command-line parameters and Windows Task Scheduler can automate scans. The software is available for Windows and macOS. Free mode permits 500 page URLs and 500 imported URLs per website. Professional is listed at $49 a month, with no fixed crawl limit and command-line support. The maker lists a fully functional 30-day evaluation period and a 30-day satisfaction guarantee. The maker also says support is free before and after purchase and usually responds within 12 hours.

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.
