The Hangar
Free SEO Bookmarklet tools, ready to go.
Predator
Hunts headings. Shows you the full structure. Scans every H1 through H6 on the page and displays them in order with a text preview.
Use it to check heading hierarchy spot missing H1’s at a glance, or verify that a page’s structure aligns with the content.
BLADE
Finds the schema. All of it. Extracts every JSON-LD structured data block on the page and displays the raw markup.
Use it to check what schema is present, verify it’s the right type, or quickly audit a competitor’s structured data without digging through source code.
RAMBO
One click. Get the full picture. Complete on-page audit in your browser. Title, meta, headings, schema, images, canonical, word count, internal and external links.
Use anytime you need to know exactly what’s on a page there and then, save to you bookmarks, use when you need it.
MEMENTO
Checks what Google is and isn’t allowed to see. Surfaces the indexability signals on any page, noindex directives, canonical tags and https status.
Use it to quickly verify a page is actually indexable before doing anything else, or to spot accidental noindex tags after a site migration.
MORPHEUS
Look’s for AI readiness. Structure and entities. Checks whether the page has enough semantic structure to be retrieved and cited by AI models: Heading hierarchy, entity signals, schema presence.
As Language models become a search channel alongside Google, this is the check most tools aren’t running yet.
GHOST RIDER
Spots the impostors. Detects elements styled to look like headings but not marked up as H1-H6 tags.
Its a common pattern in page builders and AI-generated sites. If Ghost Rider finds them, Google can’t read them as headings.
Use it on any page built with a visual editor.
