Amazon - 7% CTR on "product review pages" vs 70% CTR on "Top 5" pages

Hello,

It's been a few years I started an affiliate site principally based on amazon and I've seen that on every product review pages that I have the CTR is only 7% (Only 7% of the visitors are clicking on a link to go to Amazon) and on my "Top 5" pages the CTR is 70%.

Is it a normal thing?

I think I'm leaving a lot of money on the table, how could I improve that?

I write long quality reviews of 3000 words.

The visitors are staying very long on each pages, but they don't click.

Is it normal? Do you have any tips?

Thanks!

7% is normal
you can use a comparison table

When I said 7%, that's 7% of all my visitors that click on a link to get redirected to amazon! It feels so bad for the qualified trafic I'm getting

Do you make comparison tables on product review pages? Like "Dyson X Review"?

I do have a comparison table on my "Best X" pages but I don't really see how I could make one on a product page

Comparison table with alternative products?

Thanks!
