How to Automatically Monitor Mentions of Your Book Online
Short answer: set up a free Google Alerts alert with your book's title and your author name in quotation marks, so you get an email every time that exact phrase appears on a new page indexed by Google.
How to set it up
Go to Google Alerts and create an alert with your book's exact title in quotes (e.g., "Book Title").
Create a second alert with your author name in quotes, to catch mentions that don't include the title.
Choose "as-it-happens" frequency if you want to know right away, or "once a day" if you'd rather get a digest.
Taking it a step further with n8n
If you'd rather centralize these mentions in a spreadsheet instead of just getting emails, you can use the RSS feed each Google Alert generates as a trigger in n8n, and add every new mention as a row in Google Sheets with the date and link.
Google Alerts is free and requires no paid account; its known limitation is that it only covers content Google has already indexed, so there can be a delay of hours or days from the actual publish time.
