Where to find the most cost-effective and quality advertisement based on price?

Hello. I am looking for ads that will increase the click-through rate for our social media services panel. I have been running ads on Facebook and Instagram for a few days now, but despite optimizing them to start from 0.005 TL, the sales can be considered relatively stable on a daily basis (5-20 orders). We also have members who work with API, and about 3 to 5 of the incoming 5-20 orders belong to them. Where can we place the most cost-effective ads? Currently, our budget is a bit tight, but we definitely do not use the money generated by sales, as it goes back into advertising every morning.
