How Quickly Does Google Alerts Pickup a New Web Page

This blog is an experiment to find out how quickly Google Alerts picks up new webpages.  In this example, I have set an alert for the term:

John F. Kennedy Campaign Button for Sale

My client, Alex Cooper Auctioneers, is selling a John F. Kennedy Campaign button in their upcoming auction on February 7th, 2023.  The auction went online on 1/24/2023 at the latest.  When I create a Google Alert for "John F. Kennedy Campaign Button", their auction item does not appear. When I create an alert for " "John F. Kennedy Button" for sale " (double quotes on purpose), their auction item appears in the results, but not prominently.  When I create an alert for " "John F. Kennedy Campaign Button" auction" it appears prominently. 

Normally auctions take place every six weeks and have about 2 weeks of  ad time before the auction ends.  I'd like to know how strong a roll Google Alerts might play in people discovering an item for sale.  

I'd like to do a second comparison for this term:

Tory Burch Quilted Flap Backpack

There is also a Tory Burch Quilted Flap Backpack in the Feb 7th sale, and I'd like to see if I get an alert for that immediately.

Still no alerts.  Added a new alert with settings for "all results" and without the "for sale" modifier.
