Common Ninja is one of the most popular Elfsight alternatives — a library of 200+ embeddable widgets with a visual editor and CSS/JS customisation. For reviews, though, it has the same architectural limits as Elfsight.
This page compares Rated Stores vs Common Ninja for businesses where reviews matter.
What is Common Ninja?
Common Ninja offers 200+ no-code widgets you can embed on any site — countdown timers, image galleries, charts, audio players, Google reviews, Trustpilot reviews, and dozens more. Pricing starts at $3.19/month per widget.
Strengths: breadth, cheap entry, deeper customisation than Elfsight (CSS/JS available).
Weaknesses for reviews: scraped data, iframe-based, no collection, no compliance, no AI.
What is Rated Stores?
Rated Stores is a review-platform-first product. Every feature is built for reputation management — collecting verified reviews, aggregating across sources, displaying with SEO impact, and replying with AI assistance.

Where Common Ninja Wins
- Sheer widget variety. 200 widgets > 15. If you need countdowns + galleries + audio + reviews in one tool, Common Ninja covers more ground.
- CSS/JS customisation. Developers can deep-customise beyond template boundaries.
- Low entry price. $3.19/mo single widget is among the cheapest in market.
Where Rated Stores Wins
- Reviews you can collect, not just display. Common Ninja scrapes — Rated Stores collects.
- Rich snippets in Google search. Iframe widgets can't deliver this; Rated Stores' JSON-LD does.
- 19+ source integrations. Vs Common Ninja's handful of review sources.
- AI built in. Sentiment, summaries, reply suggestions — none of this exists in Common Ninja.
- Verified-customer checks for UK/EU compliance.
- Review management dashboard — flag, reply, audit. Common Ninja has none of this.
SEO: Why It Matters
Common Ninja widgets render in iframes. Google indexes iframe content as a separate document — your host page does not get credit for the reviews shown.
Rated Stores widgets use Shadow DOM with JSON-LD review schema injected into the host page. Google sees the reviews as part of your page and shows star ratings in search results.
For ecommerce stores, rich-snippet stars regularly produce double-digit CTR gains. This isn't a feature you add later — it's an architectural choice Common Ninja made years ago that they can't reverse.
When Common Ninja Is the Right Pick
- You want one vendor for many unrelated widgets (reviews + galleries + countdowns + maps)
- You're a developer who wants raw CSS/JS control
- Reviews are a small piece of a wider widget need
- SEO and compliance don't apply to your business
When Rated Stores Is the Right Pick
- Reviews are core to your conversion strategy
- You sell into UK or EU (compliance matters)
- You want Google rich-snippet stars
- You want to collect new reviews automatically
- You aggregate reviews from multiple sources
- You want AI-powered analysis and replies
Migration: Common Ninja → Rated Stores

Verdict
Common Ninja is a fine generalist widget library — particularly for developers who want low-cost flexibility. But for reviews specifically, a dedicated platform wins on SEO, collection, AI, and compliance.
