Little tip.. set your daily budget to about 5$.. then set it to post engagement optimization.. so it will give you traffic for whatever price.. once you see the results, you will get a ctr.. if the ctr is over a certain percentage you keep the post.. if the ctr is too low, they will charge you alot per click.. I cant tell you what you should do, because only you know what your promoting.. if the thing your promoting has a good profit.. example if 1 sale you make say 30$.. then the way you would look at it would be different than say if you convert you get 1$.. anything over 10% ctr which is 100 clicks over 1000 impressions will get you like 2-5 cent clicks.. anything about 2% get you about 10 cents per click from my experience.. everything below 1% then it starts getting costly.. and you have to figure out your return rate.. if product you pushing has huge profit if convert it might be worth it to still run ad on low ctr.. You have to become master at ads to make good money.. title, image etc are huge for ctr.. even if its a vague ad.. you would rather a deceptive ad that gets you 2 cent clicks.. than a ad thats very descriptive that cost 80 cents a click.. if the title and image are close enough, and the target is correct, from my experience you can convert.. sheeettt 40 clicks for 80 cents, may convert 2-3 offers.. where 1 click for 80 cent may not even though its extremely targeted
