I’m working with a Google Docs file that has several headings throughout the document. I already shared links to specific headings with other people via email. These links look something like:
The first part identifies my document and the second part after the # symbol points to a specific heading in the doc.
Now I need to add another heading right before the one I already linked to. The problem is I’m worried this might mess up the existing links I sent out. Is there a way to insert a new heading above the current one without changing the unique identifier of the heading that people already have links to? I can do this either manually through the Google Docs interface or write some code if needed.
Google Docs handles this way better than you’d expect. The anchor IDs stick to the actual heading element, not where it sits in the document. When you add a new heading above an existing one using the normal heading styles, the original heading keeps its internal ID. I found this out the hard way after breaking a bunch of shared links in quarterly reports because I was overthinking it. The trick is clean insertions - don’t mess with the original heading’s formatting or text. Just put your cursor right before the existing heading, hit Enter for space, then style your new content as a heading. Your links should keep working fine. Just don’t cut and paste the original heading since that can sometimes mess with the ID.
i get your worry! but don’t stress, adding a heading up top shouldnt mess with your links. they’re linked to the specific spot in the doc, not just the heading text. just keep the heading text the same to be safe.
been there with shared meeting docs! the anchor links should work fine as long as you don’t mess with the original heading. just click right before it, add your new heading, and leave the existing one alone. test one of your links afterward though - google sometimes gets weird when you change documents.
Had this exact problem managing API release docs. Always needed to add sections without breaking bookmarks.
Manual editing gets messy quick. You think you’re safe, but Google Docs is unpredictable with heading IDs when you move stuff around.
I automated it instead. Built a workflow using Google Docs API that handles heading insertions programmatically. Now I control exactly how headings get added and keep anchor links intact.
The workflow checks document structure, finds the target heading, inserts the new one above it, and verifies existing anchor points still work. Takes 30 seconds vs. manual edits and crossing your fingers.
Set it up once, reuse it whenever you modify document structure. Way more reliable.
You’re adding new headings to a Google Doc that already contains headings linked to by others, and you’re concerned that adding a new heading above an existing one will break those links. You want to add a new heading without invalidating the existing links.
Understanding the “Why” (The Root Cause):
Google Docs uses internal IDs for its headings. These IDs are associated with the heading content itself, not its position within the document. While there’s a small chance of ID regeneration if you significantly alter the heading’s formatting or copy-paste it, simply adding a new heading above an existing one generally preserves the ID of the original heading. The links remain valid as long as the target heading’s content and formatting aren’t changed.
Step-by-Step Guide:
Back up your document: Before making any changes, create a copy of your Google Doc to safeguard your work. This allows you to revert if issues arise.
Add the new heading: Place your cursor immediately before the existing heading you want to add the new heading before. Press Enter to create a new line above. Then, add your new heading using the standard heading formatting options from the toolbar (Heading 1, Heading 2, etc.). Do not copy and paste the existing heading to create the new one.
Verify links in incognito mode: After adding the new heading, test your shared links in an incognito or private browsing window. This ensures that the links function correctly regardless of any cached data in your regular browser session. If the links still work, you’re good to go. If they don’t, this suggests that there may have been a problem with formatting; try simply repeating the steps again.
Common Pitfalls & What to Check Next:
Copying and Pasting Headings: Avoid copying and pasting headings. This can sometimes lead to Google Docs unintentionally regenerating the internal ID for the copied heading. Type the new heading directly.
Extensive Formatting Changes: While unlikely, extensive formatting changes to the target heading could trigger a regeneration of the ID. If you’re making more significant modifications beyond simple insertions, back up your document to a new copy first.
Incognito Mode Verification: Always test the shared links in an incognito window to exclude any browser caching issues from interfering with your verification.

Most people here are on the right track, but manual editing can still mess things up. I’ve been there - managing docs that get shared across multiple teams is a pain.
The real problem isn’t Google Docs breaking anchor links (it usually doesn’t). It’s when you’re doing this over and over with tons of documents or major restructuring.
Manual insertion works fine until you’ve got dozens of docs to handle. I built an automated solution using the Google Docs API instead. It maps all existing headings and anchor IDs before making any changes, then drops in new content without breaking the original structure. Plus, it checks that all existing anchor links still work afterward.
This kills the guesswork and gives you something reliable you can run whenever you need to restructure documents. No more incognito testing or crossing your fingers that Google won’t randomly regenerate IDs.
