Which domain to choose for Amazon review site?

[vk_lord]

You can choose any domain and with time it will attain a nice PA, DA. However, we would advise to include a word in the domain which you will use in the titles of your product reviews.

For example; If you choose like amazonproductreviewdotcom, then you must have product review titles as amazon product review #1.
This will make your reviews SEO friendly and also get priority by Google.

I wouldn't suggest DA/PA. They are a trash metrics. Rather than those OP has many important things to look at.
