Trabzonspor president Ertugrul Dogan revealed live on Turkish broadcaster HT Spor that the club sold 18,000 season tickets in the three days following Salah's signing.
"If we reach a total of 25,000, the entire cost of the transfer will be covered," Dogan said, underlining the scale of the impact Salah's arrival has had on the club commercially.
Salah signed a two-year contract with Trabzonspor as a free agent after leaving Liverpool at the end of last season, and is reported to be earning around €17m a year, making him the best-paid player in Turkish football.
The 34-year-old was greeted by huge crowds on his arrival in the city, with local officials also moving quickly to capitalise on his profile - the mayor of Arakli, a district in Trabzon province, offered Salah a plot of land in the area during his visit.
Salah leaves Liverpool having scored 257 goals in 442 appearances across nine years at Anfield, winning two Premier League titles and the Champions League among eight major honours, and his move is already being viewed in Turkey as one of the most significant in the history of the Super Lig.
Speaking after training with his new team-mates for the first time, Salah described the reception he had received as unlike anything he had previously experienced in his career.
"The last couple of days, it's an experience I have never had in my life," he said.
"I just want to thank everyone of you for being here today and yesterday. You showed me so much love, and I never expected that reception. I'm here to win."
The move has also been framed by Turkish and international media as a significant boost for tourism in Trabzon, with an expected surge in visiting Egyptian and Arab fans seen as a further benefit of the deal beyond the club's own finances.
