Need help for Amazon affiliates.

Last month my (Outdoor Niche ) Amazon affiliates conversion was 6% but suddenly my website affiliates conversion rate are decreased. Now it is 3.5% even today affiliates clicks are more than 135 but no sell.

I have updated all of the links but still the same condition.

What I have to do now. How I can increase my conversion. Looking for expert suggestions.

Thanks

Also, 135 clicks is very low to say anything.
