January 7 marked as Swipe Sunday, with dating expert Sera Bozza warning against these profile red flags

Aussie singles have been told to bookmark this Sunday as one of the busiest days on dating apps and warned to watch out for these red flags.

Tinder data reveals activity on the dating app soars on the first Sunday of the year, with a dating expert calling on those looking for a relationship to polish up their profiles and avoid major online dating red flags.

Tinder dating expert Sera Bozza said her “No.1” warning for singles was to avoid being negative and using phrases like “don’t swipe on me if you’re gonna ghost or if you’re gonna do this or that”.

“It’s really sad because it’s so obvious that the person you’re talking to has been burned in the past,” she said.

“The person themselves probably thinks they’re protecting themselves from that kind of behaviour, but to be on the opposite side of the screen, you’re like: ‘This person is so negative, I do not want this energy’.

“It ends up almost being a self-feeding cycle because you’ve been burned in the past, but then it’s so negative, no one want to go anywhere near you.”

The Sydney-based dating coach also advises against writing out “laundry lists” or getting too specific on ultimatums.

“You don’t need to put rules on the other person. If you do have a laundry list, keep it in your head,” she said.

“If there’s something in the other person’s profile, for example you see them holding a cigarette in multiple photos, you can just think this person is probably not for me, and therefore, I’m not going to swipe on them.”

The warning comes ahead of the first Sunday of the year – January 7 – which is responsible for 22 per cent increase in the number of messages sent on Tinder, with users also responding by an average of 19.4 minutes faster compared with other Sundays in the year.

Tinder has coined the day Swipe Sunday, which delivers an 18.2 per cent boost in the number of likes compared to the rest of the year.

Tinder spokeswoman Kirsty Dunn said the first Sunday of the new year was globally one of the “busiest days of the year on dating apps”; however, Australians also had the advantage of longer summer days and warm nights.

Singles have been told to polish up their profiles, as use of dating apps skyrockets on the first Sunday of January.

The enthusiasm lasts from the first Sunday of January all the way until February 14 – or Valentine’s Day.

“During this period there are 11.4 million more messages sent globally compared with the rest of the year and a stunning 58.7m more likes sent compared to the rest of the year,” Ms Dunn said.

“Many Aussies have spent the holidays self-reflecting, so they’re armed with their NY resolutions and intentions, and making new connections is top of mind.”

As for the most controversial opening line, Ms Bozza says it’s the simple three-letter word “hey”.

“There’s one side of people who are like that is disgusting, it’s audacious, it’s lazy, you’ve got to put in more effort,” she said.

However, she says people shouldn’t be too quick to judge.

“You are technically a total stranger and maybe you didn’t give them enough to work with on your profile,” she said.

“Let’s be real: If someone approached you in a bar or a cafe, you wouldn’t expect them to come at you with fireworks. A simple, ‘Hey, how are you?’ would do the trick and we all know it translates to ‘Hey, I noticed you, I think you’re cute’.

”On Tinder, just matching with someone is saying the exact same thing.”
