keyphase + "review" boost ranking ?

In an article suggested for the topic of SEO for product Review, the author has suggest that google will rank in favour of keyword phase plus "review". That means if your site is doing some product review, or you keyword is targeted with this "review" phase, google will give you a higher ranking.

I will probably try this out as my website is somehow about review too. I shall try to include "review" into my keyword and see what it brings to the SERP changes.
