I consult for a 7-figure ecommerce business, and here's what we've observed about reviews...

They're important, but not the MOST important thing.

To get more reviews, we will send a post-purchase email a few weeks after the product was purchased to leave a review. Most good ecommerce businesses I know follow a similar strategy (review email post-purchase).

In general, a good strategy for understanding whether something works is to observe what the most successful companies are doing! Sign up for their newsletters, look at their popups.

To give you actual data, we send our review email 30 days after purchase. We see a 51.3% open rate, and 9.1% click rate. Use these numbers as a baseline for your own numbers.

What we've noticed is MORE effective than reviews are referrals from friends. In other words, incentivizing friends to share with their friends and become ambassadors for your brand.

Since it's against most terms of service for review sites (like Google, Yelp, and Amazon) to incentivize for review you can't do it there.

However, we often do something like "give $10, get $10" using a tool like ReferralCandy (no affiliation). In fact, another company I help generated five figures in income last month through referrals alone.

Hope this helps. If you have any follow-up questions, feel free to book a call. Can answer a bunch more questions about reviews and what we've done in less than one hour.
