Unfortunately I think you will find a budget of 15€/day a little too low to see much traction quickly. Most advertising platforms have gone all in on ML in a way that until you have had a significant amount of traffic they can't really train their algorithms. I would consider a sorter sharper campaign to see what you can achieve. From our experience you need to be spending 8-10x that per day to kick start a campaign on Facebook. Additionally, depending on your projects market Facebook/Instagram results can vary very widely. Targeting is hard, you can obviously use Facebooks audience tools to try and target but from our experience these can be difficult to get right. Without a little more information about your project I can't really suggest anything else. This is where the ML targeting is essential but as I said that need significant traffic to work. > Facebook ... say they sent 300 clicks in a week, but I only see 120-130 in Analytics This is about right from our estimation, it's a fairly new occurrence and down to Apples tracking changes that came in with iOS 14.5. If your target market are likely to have a large proportion of iOS users the tracking of Facebook ads has gotten quite bad. We estimate that up to 60% of iOS clicks are not tracked by Facebook/Analytics, Facebook obviosly know someone clicked the ad, but after that the tracking can break very easily. This is particularly bad for conversion tracking. We have also experienced big problems with tracking people who leave the Facebook in app browser and move to their main browser to continue. We have found popping up a message encouraging them to open in their main browser if they try to navigate away from the landing page works well. It ensures that any Facebook/Analytics url args are still present in the URL when they move browser, setting a new tracking cookie based on them. When we introduced this before Christmas we saw a massive increase in general trackability with Facebook. > Are there any other platforms that are more suitable for my budget? I would consider Google search result ads, it potentially allows you to target people who are already looking for something like what you are doing. It tends to have a significantly higher conversion rate than display advertising. Particularly at your daily budget it would be easer to play with, although at 15€/day you will only be getting 10-20ish (ballpark) clicks per day. If you have a conversion rate of say 2.5% (again about ballpark) then that's about 1 conversion every two-four days.
