Local Client's Website & Review Snippets

Hey Guys and Gals,

One of my clients has some great metrics and been established for a long while - the website has strong trust flow, citation flow, pa and da, though does not perform.

The business has a large amount of reviews on google, trust pilot, etc; at the bottom of most of the site's pages currently are testimonials from customers to simply build trust for visitors and get them to call.

My question is, is it worth changing all these to review snippets, with review url's pointing to the original site they are posted on?

I assume this will increase the click through rate, if shown by Google, though will placing a snippet on every page have a positive effect / what's your recommendations?

Thanks

Google uses many metrics to determine ranking. Traffic is the catalyst for all the elements that go into local rankings. Now I can't say for sure that this will have any effect on your rankings, but a backlink couldn't hurt.

Any other thoughts on this?
