How to know if keyword has sound searches?

[bilawalgul]

Is there any way to know how many searches for a particular keyword have within Fiverr. My specialty is product description and after months of consistency I have reached to the first page on major keywords related to product description, i.e;

Amazon Product description
Product description writer

On both keywords, I am dominating the first page without any review. Still, I am not getting orders I don’t know what is wrong. Can anyone help me guidance what else could be improved in the Gig in order to receive the order.

Are these keywords not worthy to be ranked on? Should I work on other gigs instead of Product description?

Here is a link of my gig: https://www.fiverr.com/bilawalgul/write-appealing-product-description-for-amazon-and-web

Kindly advice. Thanks.
