Should I keep an unprofitable campaign running for organic ranking?

I have a product that has a low rating. Right now I am just running one auto campaign that is losing money but TACoS is low and I am still making money as a whole each week, though not a lot. The campaign doesn’t spend its budget and contributes to almost no sales (I also get little sales overall) but I’m worried if I pull it and have no ad campaigns that I will losing organic sales. What should I do? Thanks!
