What a review widget does

How review widgets affect website conversion rates

A review widget is a piece of code you embed on your website that displays your live review rating, review count, and often individual review snippets. It updates automatically as new reviews come in.

The conversion rate impact comes from the trust it builds with website visitors who have not yet seen your Google listing. A visitor who arrives from a social media post, a Google ad, or a direct referral has not yet seen your Google reviews. A review widget brings that social proof directly to your website at the point of decision.

The size of the conversion rate improvement depends on where the widget is placed, how many reviews you have, and what your rating is. A widget in the hero section of a high-converting landing page with 4.7 stars and 80 reviews will produce a larger uplift than one buried in the footer.

Best practices

How to maximise conversion rate improvement from a review widget

1

Place it above the fold on your highest-traffic pages

The homepage hero section, the contact page, and any landing pages you drive paid traffic to are the highest-impact placements. These are where new visitors make their trust decisions.

2

Display the rating number and review count prominently

A star graphic alone is less impactful than a combination of the rating number, star graphic, and total review count. The specific numbers are the social proof. Stars without numbers are decorative.

3

Add a link to your Google listing for verification

Make the widget clickable and link to your Google Business Profile. This verification option increases credibility because it signals the reviews are real and independently verifiable.

4

Only display if your rating is 4.0 or above and you have at least 10 reviews

Displaying a widget with a low rating or very few reviews can hurt conversion rates rather than help them. Build your review base first.

5

Keep it fast-loading

A well-built review widget should have minimal impact on page load speed. Avoid widgets that load large numbers of review snippets on page load.

Frequently asked questions

Common questions

A review widget is an embeddable code element that displays your live review rating, count, and review snippets on your website, updating automatically as new reviews come in.

Research suggests adding a review widget to a page that previously had no social proof increases conversion rates by 10 to 30 percent on average. The improvement is largest for businesses with more than 30 reviews and a rating above 4.3.

Google reviews are the most universally recognised and trusted source. Display your Google rating primarily. If you have a strong Trustpilot presence for UK and European audiences, you can display both.

A well-built widget should have minimal performance impact. Avoid widgets that load large numbers of review snippets on page load. A widget showing just rating, star graphic, and count is most performance-friendly.
