User reviews

HeadingsMap is praised for its effectiveness in accessibility testing, SEO heading analysis, and navigation of complex web content. Users value its simplicity and fast performance. However, multiple reviews complain about the removal of HTML5 section analysis, inconsistent functioning on many sites, and conflicts with certain web applications. There are also requests for better export features and customization options. Despite some bugs and occasional crashes, it remains a useful tool for web developers, SEO professionals, and academic readers.

I use this for accessibility testing and it is a wonderful extension. Great job!

the extension differed from all others by the ability to work with HTML 5 - now it has been removed. What is it for then? the rest of the functionality is always full in other SEO tools = return it, but for now 1 point

Очень полезный плагин для контроля структуры страниц с точки зрения заголовков и блоков по SEO.
