Pinterest experiences growth following earnings. Cramer predicts the stock's continued success in the long term.

Cramer believes in Pinterest's reinvention plan, citing its strong third-quarter earnings report as evidence.

Under CEO Bill Ready, who assumed leadership in June 2022, Pinterest is now converting all its user interest into ad sales, according to Cramer on "Squawk on the Street." Pinterest's new emphasis on improving the shopping experience benefits both users and advertisers. Pinterest is a digital pinboard where people seek inspiration for interior design, fashion, and more.

"This platform, along with Meta (Instagram's parent company), is now a destination for you to advertise on, keeping you in one place," Cramer stated.

The CNBC Investing Club utilizes the portfolio of Cramer's Charitable Trust, which contains shares of Meta, the parent company of Facebook and WhatsApp. Although Meta is significantly larger than Pinterest, both companies generate the majority of their revenue from advertising.

On Tuesday, Pinterest's shares increased by more than 19% to approximately $30 each, following the release of better-than-anticipated third-quarter results on Monday evening.

"This stock will be a long-term winner and will go higher, as Cramer stated," said Cramer.

Cramer was impressed by Pinterest's 11% revenue growth, improved profitability, and expanding user base. The company's global monthly active users increased by 8% compared to the previous year, reaching 482 million.

Cramer considers Pinterest's recent ad partnership with Amazon, which is also owned by his trust, to be "very smart."

Pinterest's earnings call on Monday revealed that the company is happy with its Amazon partnership, which was announced in late April. Ready stated that the "most significant" revenue impact will be seen starting in early 2024.
