Australian visits to Missguided have declined 78.4% since 2019, according to SEMRush analysis.
The data showed a severe decline in traffic in September 2021, falling 77.54% from the month prior.
In the first four months of 2022 compared to 2021, site traffic declined 46.43% representing a loss of more than 252,000 visitors over that period.
The result was despite a strong Q1 2022, where traffic increased year on year by 19%.
Last week, Frasers Group salvaged the brand from administration by securing certain intellectual property for a cash consideration of £20 million.
Following completion, the business will be operated by the administrator under a transitional agreement for a period of approximately eight weeks.
It is then the intention that Missguided will operate as a standalone business within the Group.
Frasers Group CEO Michael Murray said he plans to leverage its digital-first approach.
"We are delighted to secure a long-term future for Missguided, which will benefit from the strength and scale of FG's platform and our operational excellence," he said.
"Missguided's digital-first approach to the latest trends in women's fashion will bring additional expertise to the wider Frasers Group."
