Facebook Ads Retargeting Question

Hi everybody, hope you doing well.

I run Facebook Ads and I started to do Retargeting because I have low results. I want to share my retargeting options to you and to hear any opinios about it because I still have no results even with retargeting ads.

So I have an Ad containing Dynamic Creatives, 3 images with general information bout my services with "Traffic" Objective.

Also I have created Custom Audience with Page View traffic, 2 days retention, 4 days 6 and 8 days retention. 4 Custom Audiences.

Now I have made 1 Ad that has 4 Ad sets, all of them containing 4 different images like 1 ad set - 1 image.

So my Retargeting strategy is like this:

1st Adset - 1 creative. Audience Include - Traffic that went to my website 2 days retention.
2nd Adset - 1 creative. Audience Include - Traffic that went to my website 4 days retention. Audience Exclude - 2 days retention
3rd Adset - 1 creative. Audience Include - Traffic that went t my website 6 days retention. Audience Exclude - 4 days retention
4th Adseet - 1 creative. Audience include - Trffic that went to my website 8 days retention. Audience Exclude - 6 days retention

My strategy is to show different creatives during 8 days. Every 2 days different creatives.

I hope I wrote everything well to make you understand what I did.
I would like you guys to tell me your opinions about my retargeting strategy and if I made it in a correct way. Maybe I did something wrong somewhere and I have no leads. Thank you in advance and hope to read some opinions and maybe some advices on how to improve what I have now. Thank you.
