Will Google index this reviews?

1. It is up to Google. They are output in a format that Google looks at, but if they don’t think your page has enough authority they may not display in search results. Nothing we can control.

2. If there are more words, it will affect keyword density. My standpoint is that your customers will use phrases relevant to your topic in their reviews so it actually helps you out and adds more searchable phrases to the page.

Google uses a complicated formula that uses links to pages and references to establish credibility of the website or page.
