A practical little workflow

From “I need to…” to done.

01

Describe the visible trail

Add at least two ordered levels, with a display name and full HTTP(S) URL for each.

02

Review the hierarchy

Check the names, order and URLs against the navigation your visitors actually see.

03

Validate on your own page

Download JSON-LD, place it in an application/ld+json script on the matching page, then use Google’s Rich Results Test.

Will this improve my search ranking?

There is no ranking or rich-result guarantee. Structured data must follow Google’s guidelines and match visible content. Breadcrumb presentation also depends on search surface and eligibility.

Does this generate the visible navigation?

No. It exports JSON-LD data. Your website still needs its own visible, accessible breadcrumb navigation.

Can I insert the file directly as HTML?

Use the JSON inside a script element with type application/ld+json. When embedding manually, escape any < character as \u003c to prevent an embedded closing-script sequence. Validate the final page.

What happens to my data?

Working text and local files are processed in this browser tab and are not sent to a server or an AI service. Reloading clears this workspace. Optional analytics and feedback have separate privacy controls; see Privacy below.

Your work stays yours.

Files and text are processed in this browser tab. The tool does not upload your working files or text. Feedback is optional: opening Feedback loads a Tally-hosted form, and submitted feedback is processed by Tally. The form is not attached to your working files. No advertising is installed. On our official lavmio.com websites, optional Google Analytics loads only after you allow it. It measures visits, approximate location, device/browser information, tool completion and download actions. Working files, text, filenames and form contents are not attached. Page query strings, fragments and referrer paths are excluded. We disable advertising features and automatic form/link tracking. Your preference is stored for six months across Lavmio websites; Google Analytics cookies also expire after six months. Use Analytics choices in the footer to change your choice or withdraw permission. Google processes measurement data; see how Google uses information from partner sites. Preview addresses do not run analytics.

Campaign presets are stored only when you choose Save. Other workspaces are cleared when reloaded. Like any website, the hosting server can receive ordinary page-request information, such as your IP address.

Downloads are saved to your device. Check results before using them in a production workflow.
