User Reviews

Mangools SEO extension provides a user-friendly and comprehensive set of SEO tools comparable to its Chrome counterpart, appreciated for its helpfulness and time-saving features. However, its free version is limited, requiring registration and subscription to access most features. Users report issues with language support and login functionality. Overall, it is considered a sophisticated SEO tool with valuable metrics, but some usability hurdles remain due to payment and technical drawbacks.

Pros

User-friendly interface with easy handling and good overview of key SEO metrics like DA, PA.
Time-saving for SEO experts, providing sophisticated and helpful SEO options.
Free version offers limited usage such as five keyword or website lookups, allowing some basic functionality without immediate payment.

Cons

Most valuable features are locked behind a paid subscription, limiting free usage significantly.
Requires users to register an account to access full services, which may be inconvenient.
Issues with language support, especially with Lithuanian CAPS letters not displaying correctly in snippet previews.
Login problems where the extension fails to recognize premium login and causes a registration loop.
