2. Sitebulb: A Visual Approach to Auditing

Key Features:

Visual Data Representation: Sitebulb’s ability to present audit results through graphs, charts, and node structures makes it easier for users to digest complex data. 

In-depth Technical Audits: It flags common SEO issues such as broken links, duplicate content, missing alt text, and thin content, giving users specific recommendations for improvement.
