FIX GOOGLE AD OR PROVIDE AN ALTERNATIVE

I sell health supplements and I get my orders from google ads, but unfortunately I want to believe there is a problem with google's algorithm, unlike how it used to be, my ads now run with thousands of click with very little to no orders (most times zero orders) coming into my order form... besides this the whole responsiveness of ads is missing... something seems amiss with the google ad.

I want someone who can fix this or possibly profer an alternative setup for me that will get my orders popping in again.

Thanks
