Heading Structure CheckerTASK
Work only with current page inspected through approved read-only DOM code. Export heading levels and text, flagging missing or skipped structure for review. Create a CSV file named webact-heading-structure-checker.csv. Keep the complete file under 48,000 UTF-8 bytes. If required, propose a read-only run_js inspection of the current document for my explicit approval. Do not fetch URLs, access credentials, execute remote code or change page content. Use only observed content and facts I supply. Keep missing values unknown. Preserve IDs, dates, units and currencies. Report omitted, truncated or unreadable content; do not claim full coverage. Verify the output against the source and stop if the required input is unavailable. Keep one header row, consistent columns, escaped quotes and literal spreadsheet-safe text. Ask me for any required settings or source facts that are missing before starting. Start with up to 25 records or one short document. Report exactly which source content was included.

Paste in Task mode with Browser model selected.

Make it yours. Specify the fields, tone or level of detail you need. Keep the original facts and mark anything that needs your review.

A PRACTICAL GUIDE

How to inspect a webpage's heading structure

Headings help readers and assistive technology understand how a page is organized. A heading inventory makes it easier to spot unclear hierarchy or sections whose labels do not describe their content.

Start with the right material.

What you provide
current page inspected through approved read-only DOM code.
The intended result
Export heading levels and text, flagging missing or skipped structure for review.

How the workflow works.

Record the heading text and level in page order. Consider whether the relationship between sections is understandable rather than treating every numbering jump as the same kind of problem.

What to check in the result.

Review the actual content around a flagged heading before changing it. Visual size and semantic heading level can differ, so inspect the markup when the supplied view is incomplete.

Import the CSV with a consistent delimiter and inspect text identifiers, dates and amounts before using spreadsheet totals. Keep the original file available while checking any automatic type conversion.

Learn from the worked example.

The downloadable CSV example uses these columns: Position, Level, Heading, Observation. Compare a complete record with the source before sorting, combining or importing your own output.

The supplied example is illustrative. It is not a recorded run on your data.

Chat or Task? Choose your mode
What input does this Heading Structure Checker need?

current page inspected through approved read-only DOM code. Expand the relevant content and share only the context needed for this task.

What should I check in the result?

Report shows the hierarchy jump with exact headings. Only the selected visible content is included. Missing facts stay unknown; verify the result before use.

Is this a full SEO audit?

This is a check or draft for one current document. It does not crawl a site, measure rankings, query a backlink database or guarantee search performance. Review observations against the actual page.

Can I use this on the Free plan?

Yes. Install the Chrome extension, verify your WebAct account and use an available ChatGPT browser connection in the same Chrome profile. Free includes 25 user-started automation tasks per calendar month (UTC), shared across all tools. A task counts when its first action starts; steps and necessary retries within that task do not count separately. Provider limits apply. After 25 tasks, upgrade or wait for the reset.

Does this page run the task?

This page provides an illustrative example and a task to copy. Run it through WebAct on the source page you activate. Selected page context is processed by your browser AI provider. An ordinary answer in browser Chat uses no WebAct automation allowance; creating a file or changing fields in Task mode does.
