This means:
“The post promises 15 useful household tips involving baking soda, presented as practical tricks that women should know.”
Breakdown
“15 brilliant tricks” = promises a list of clever, useful applications.
“Baking soda” = sodium bicarbonate, commonly used in cooking, cleaning, and deodorizing.
“Every woman should know” = a marketing-style phrase suggesting these tips are essential knowledge, though the tricks aren’t specifically limited to women.
Tone
This is household/lifestyle clickbait. The number 15 makes it feel comprehensive, while “brilliant” and “every woman should know” make the tips sound unusually valuable or essential.
A simpler version:
“15 useful ways to use baking soda around your home.”
