The Scenario
Your agency landed a competitive audit project. The client wants above-the-fold comparisons for 30 competitor landing pages — layout, CTA placement, hero copy — and the account manager has already promised delivery by end of day Thursday.
Column A of the "Competitors" worksheet has all 30 URLs. Column B is empty.
The bad version:
- Open each URL in a browser, trigger the Serpdog screenshot API call manually, wait for the capture, copy the output image URL, paste it into column B, close the tab, find your place in column A, open the next URL
- Repeat 29 more times across three different browser windows because you kept losing the workbook in the taskbar
- Discover at row 22 that two URLs redirect and the screenshot captured the redirect destination, not the page you wanted — and you have no idea which ones because you were not checking
Thirty URLs takes about two hours that way, and the audit itself — the part you were actually hired to do — still has not started.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It reads the workbook, understands the data in context, and talks to Serpdog on your behalf. Open the SheetXAI sidebar, and give it this prompt:
For each URL in column A of the "Competitors" worksheet, use Serpdog to capture a full-page desktop screenshot with a 2-second load delay and write the resulting screenshot URL into column B
What You Get
- Column B fills with Serpdog screenshot image URLs, one per row, aligned to the source URL in column A
- Any URL that fails — redirect loop, timeout, 403 — gets a brief error note in column B instead of leaving a blank that you might not notice
- The "Competitors" worksheet stays intact; nothing else in the workbook is touched
- The entire 30-URL run finishes in a fraction of the time it would take manually
What If the Data Is Not Quite Ready
Some URLs in column A have trailing slashes, others do not
Normalize all URLs in column A — remove trailing slashes and ensure each starts with https:// — then use Serpdog to capture a full-page desktop screenshot of each and write the screenshot URL into column B
Column A has a mix of live URLs and placeholder text like "TBD" or "N/A"
Skip any row in column A where the value is not a valid URL, use Serpdog to screenshot the valid ones, and write the screenshot URL into column B — leave skipped rows blank
The URLs are split across two worksheets — "Tier 1" and "Tier 2" — and you need both captured
Combine URLs from the "Tier 1" worksheet column A and the "Tier 2" worksheet column A, use Serpdog to capture a full-page desktop screenshot of each, and write the screenshot URL back into column B on the matching worksheet for each URL
You need the screenshot, plus a note on whether the page loaded correctly, all in one pass
For each URL in column A of the "Competitors" worksheet, use Serpdog to capture a full-page desktop screenshot — if the capture succeeds write the screenshot URL into column B and "OK" into column C, if it fails write the error message into column B and "FAILED" into column C
The fastest approach is always to ask for the cleanup and the action in the same prompt — one instruction handles both.
