Track competitor price changes in real-time without manual monitoring

Set up a Google Sheet that scrapes competitor pricing daily and flags changes so you respond to price wars the same day.

  1. 1Create a new Google Sheet with columns: Competitor Name, Current Price, Previous Price, Change %, Last Updated, Alert Status.
  2. 2In the 'Current Price' column, use this formula for each competitor's pricing page: =IMPORTHTML("https://competitor-url.com/pricing", "table", 1) (adjust table index if needed).
  3. 3In a helper column, use =IF(ABS(B2-C2)/C2>0.05, "YES", "NO") to flag price changes above 5%.
  4. 4Set the sheet to recalculate daily at 8 AM by going to Extensions > Apps Script > trigger settings.
  5. 5Share the sheet with your marketing team and set up a Slack webhook to notify #marketing when a competitor price changes.
  6. 6Test by manually changing a competitor's price to confirm the formula and alerts work.
