What’s a Google alert? It’s an automatic notification that Google has found something new matching search terms of your choice. It’s very handy.
I have just discovered that for some time now many of my carefully crafted Google alerts have not been working. The reason is that I had used the + search operator. Until a year or two ago, + could be used to force Google to include a particular +word in the search result. No longer. Now you must do the same thing by putting quote marks around the “word”.
I read about it when the change happened, and have used it when searching, but it never occurred to me to check that my alert search terms still worked.
So, go and check your Google alerts!
