It's relatively minor for most businesses, but sometimes it isn't. Inconsistent messaging makes it a lot easier for someone to set up a phishing attack against your customers. My bank uses several different URLs, email sending addresses, and taglines for its services. It's not always easy to tell if an email is actually from the bank.

Google adding more permutations into the mix doesn't help.

Google changing the way title tags are formatted on their SERP is not the reason that your bank's customers are falling for phishing attacks.

Of course not. I didn't say it is. It's a whole bunch of things. Google changing things is one very small factor.

But it is a factor...
