The Review Schema Engine generates valid JSON-LD structured data for reviews and star ratings — the markup behind the rating stars you see in Google results and the review snippets AI engines cite. Pick a mode (a single Review, an AggregateRating on a Product, an AggregateRating on a LocalBusiness, or Review plus AggregateRating combined), fill in the item name, author, rating value, review body and counts, and the tool builds a ready-to-paste script block, live-validated with a required-field checklist so you know the markup is complete before publishing.
This free tool by Hosting Cambodia is ideal for hotels, restaurants, shops and service businesses in Phnom Penh, Siem Reap and across Cambodia that collect genuine customer reviews and want them reflected as rich results. Star ratings in search results dramatically lift click-through rates, and structured review data is one of the clearest trust signals AI answer engines read. Remember the golden rule the tool also warns about: only mark up real reviews that are visible on the page — fake review markup risks Google penalties.
Frequently asked questions
Will this markup guarantee star ratings in Google?
No tool can guarantee it — rich results are always at Google's discretion. Valid, complete markup for genuine on-page reviews is the prerequisite; from there Google decides per query whether to display the stars.
Which mode should I choose for my business?
Use AggregateRating on LocalBusiness for your homepage or Google-style overall rating, AggregateRating on Product for product pages with many reviews, and single Review or the combined mode when you display individual customer testimonials alongside an overall score.
Is it safe to mark up reviews I collected on Facebook or Google?
Only if those reviews are actually displayed on the page carrying the markup. Structured data must describe visible page content — marking up ratings that appear nowhere on the page violates Google's guidelines and can trigger a manual action.
