Frequently Asked Questions

What makes Black SEO Analyzer different from other SEO tools?

Unlike traditional SEO tools with browser-based interfaces and subscription models, Black SEO Analyzer is a command-line tool that integrates directly into your development workflow. This approach enables automation capabilities that aren't possible with other tools, plus you genuinely own the software with a one-time purchase.

How does the source code guarantee work?

Your purchase includes a legally-binding commitment that gives you access to the full source code if we ever discontinue the product, cease operations, or fail to provide updates for 12+ consecutive months. This ensures you can continue using the software indefinitely, regardless of our company's future.

Is Black SEO Analyzer difficult to use for non-developers?

The tool is designed primarily for technical users comfortable with command-line interfaces. If you're a developer, system administrator, or technical SEO professional, you'll find the interface intuitive and efficient. For non-technical users, browser-based tools may be more appropriate.

How are updates handled?

Updates are provided via our GitHub repository and automatically checked by the tool itself. When new versions are available, you'll be notified when running the program. You'll receive all future updates at no additional cost.

What's the difference between the free trial and the paid version?

The free trial allows you to analyze up to 3 pages for feature demonstration purposes, so you can try before you buy. The paid version removes this limitation and includes all advanced features plus our source code guarantee.

Can I use Black SEO Analyzer in automated environments?

Absolutely. The command-line interface makes it ideal for automation. You can integrate it into CI/CD pipelines, cron jobs, scheduled tasks, or custom scripts. All output formats are designed to be machine-readable for further processing.
