For teacher-authors and course creators

Keep the links in your teaching-resource PDFs usable

A workbook activity sends learners to a museum page, video or teaching resource. Months later, that destination moves while your PDF stays unchanged. A useful maintenance check tells you which resource, version and PDF page need attention, so you can review the activity and update the source.

Pagekeep’s current PDF link checker for teacher resources is an email-operated pilot. Request a limited free check; a page-specific report is due within 24 hours of acceptance. Planned $19/month monitoring is waitlist-only. No payments are collected.

A checklist you can use without signing up

Download the link-maintenance checklist (CSV)

The download is a blank audit sheet with named columns, ready to open in a spreadsheet. Use one row per link occurrence, even when several pages share a destination. No account, email address or file submission is needed to use it.

1. Identify the export. Record the file name and version, then use the PDF viewer’s page number rather than relying on printed labels.
2. Capture the destination. Record the linked URL behind the text or image. Check written addresses too; the visible URL and clickable target can disagree.
3. Date the check. Record the last checked date, result and any redirect destination. Preserve evidence before deciding what needs repair.
4. Separate uncertainty. Keep blocked, rate-limited, login-required and incomplete checks distinct from confirmed missing pages. Add a review action rather than guessing.
5. Choose the next step. Record a verified replacement URL or a decision to remove or rewrite the activity. Review classroom suitability yourself.
6. Close the loop. Record the new file version, export recheck and republish date. Set a next review date that suits how often you maintain the resource.

The CSV includes all these fields plus notes. Empty cells are intentional: fill them with your own audit evidence. Keep student information and private access links out of a shared maintenance sheet.

Before publishing and after release

Before release, check the final exported PDF rather than only the editable document. Click annotation links and compare them with any written URLs. Open the destination as a reader would, without relying on an author’s signed-in browser session. A successful response does not prove the right worksheet or video is available.

After release, choose a review schedule based on your resource library. A rarely updated file may only need a one-off audit before reuse. A frequently maintained collection may benefit from repeated checks with file versions and page references. Recurring checks still need a creator to decide whether an activity remains accurate and suitable.

Follow one real demonstration finding

Open the Curious Planet demonstration PDF at viewer page 10 and find the micro:bit projects activity. The existing sample records the destination below:

Next, open the full sample report and expand its request evidence. Locate the same URL and page before deciding on a replacement. The report records observations from 1 November 2026 UTC; those findings are historical, not a current availability claim.

Compare that confirmed failure with NOAA education on viewer page 1. Its automated request returned HTTP 403 and stayed unverified. A bot block is not evidence that learners cannot use the page. Redirected destinations also need manual review rather than an automatic broken label.

This workbook is an original demonstration, not a customer case study or vetted curriculum. It contains six deliberately invented stale-looking URLs; they are not known historical resources. The page-10 micro:bit link was not one of those invented paths. The sample provenance explains the seeds and the limits, including an invented URL that returned HTTP 200.

Update the resource after a finding

Verify a replacement in a browser and read enough of the destination to assess the activity. Check age suitability, access requirements and whether the instructions still make sense. Pagekeep checks HTTP access, not educational quality.

Edit the original document, updating both the visible address and embedded link where needed. Regenerate the PDF and recheck the exported targets. Re-upload the new resource to your distribution locations, then record its version and republish date in the checklist.

Previously downloaded copies keep their old links. Pagekeep does not edit files, update store listings or fetch replacement PDFs automatically. No TpT or course-store credentials are required; you handle publication and send a new PDF when you update it. Pagekeep is not endorsed by Teachers Pay Teachers or a learning platform.

Request the current free email check

Email one PDF you own or have permission to share, or a download link you control. Include “I have permission to share this file.” The free pilot supports up to 10 pages, 50 unique public URLs and 10 MB, with one free check per creator and five free checks total across the pilot.

The report is due within 24 hours of acceptance. This is not an instant upload scan. Remove student records, credentials, private links and signed URLs first. Scanned or password-protected PDFs, login-only resources and content-quality review are outside the pilot. Read the handling and deletion explanation; free-check working files are deleted within seven days of delivery.

For libraries needing recurring checks

Planned monitoring is $19 USD/month and remains waitlist-only. The planned scope is up to five PDFs, 10 MB each, and 300 unique public HTTP(S) URLs across the files. Planned weekly emailed reports would preserve document versions and page mappings and include a repair list and request evidence, even when nothing changes.

No payments are collected and no card is requested. Joining the waitlist is optional and is not a condition of a free check. Review the full offer and limits before expressing interest.
