Social media users were out in full force on Tuesday tweeting photos and commenting on McDonald's launch of all-day breakfast.
Data from LikeFolio, a company that measures "purchase intent" enthusiasm for brands and products owned by public companies, revealed that purchase intent mentions for two breakfast sandwiches spiked after the launch, with McMuffin mentions up sevenfold and the McGriddle up sixfold.
Usually, the Big Mac is the chain's most-mentioned menu item on Twitter, but Tuesday, it slipped to No. 3 behind the McMuffin and McGriddle.
"It's a successful first day," Andy Swan, co-founder of LikeFolio, told CNBC. "It's not as enthusiastic as we saw for [Taco Bell's] Doritos tacos, which was a complete outlier that we may not see again. But this is a very positive, successful launch."
Of course, the enthusiasm for buzzy new products, or in this case, hash browns at noon, usually dissipates quickly after the initial launch. But Swan says that companies that can sustain shoppers' passion are often rewarded with big sales numbers.
The iPhone 6, for example, got a lot of love from Twitter users in the last year, and sales of the phone topped 10 million in the first three days, according to Apple.
Obviously, winning on Twitter doesn't guarantee a home run, but the spike in enthusiasm could indicate much-needed positive growth for McDonald's.
