You installed a reviews app last quarter. The stars still missing from half your product templates. The hub page is a blank section. Support still owns every fit question. This afternoon is for finishing the theme work. Leave the app bake-off for another day.

In this article
Four surfaces, one afternoon: product stars, reviews hub, Q&A, thank-you ask.
Four surfaces, one afternoon: product stars, reviews hub, Q&A, thank-you ask.

We make Idukki. On Shopify its theme blocks cover Product Rating Stars, review layouts, Q&A and a thank-you invite. Stars can emit optional review JSON-LD. The steps below fit any reviews app that ships theme app blocks. Stay inside one product for the afternoon.

The 90-minute clock

Afternoon setup, timed

  1. 01

    0–10 min: app + embed

    Confirm the app is installed. Enable the app embed in the theme editor.

    10 min

  2. 02

    10–30 min: PDP stars + list

    Add rating stars near the title. Add the review list below the fold on one product template.

    20 min

  3. 03

    30–50 min: hub page

    Create or edit /pages/reviews. Drop the hub or all-reviews block. Link it from the footer.

    20 min

  4. 04

    50–70 min: Q&A

    Add the Q&A block to the same product template. Seed two answers from support.

    20 min

  5. 05

    70–85 min: thank-you

    Add the thank-you or order-status block that asks for a photo or review.

    15 min

  6. 06

    85–90 min: QA pass

    Run the checklist below on phone and desktop, then publish.

    5 min

Use a duplicate theme or a theme preview. Publish only after the QA pass.

Install order that avoids broken previews

  1. 1Install or open the reviews app in Shopify admin.
  2. 2Online Store → Themes → Customize → App embeds: turn the reviews embed on.
  3. 3On a product template, add Product Rating Stars (or equivalent) under the title.
  4. 4Add the review list / photo reviews block where shoppers expect proof.
  5. 5Create the reviews hub page and place the hub block.
  6. 6Add Q&A on the product template; seed at least two answers.
  7. 7Open Checkout → Thank you / Order status customisations; add the post-purchase block.
  8. 8Preview as a customer on mobile; then publish the theme.

Shopify's thank-you and order status app blocks work on plans below Plus. You do not need Plus only to ask for a review after payment.

Product stars and structured data

Stars near the title answer "is this trusted?" before the fold. The review list below carries the bodies and photos.

If your block offers "Add SEO structured data", limit it to first-party reviews on that page. Google's guidelines say not to mark up ratings aggregated from other websites. Imported Google or Trustpilot scores can stay visible; leave them out of the JSON-LD.

Hub, Q&A and thank-you

  • Hub: a /pages/reviews URL with filters. Shoppers and crawlers can browse proof off the PDP.
  • Q&A: one block on the product template. Seed from the support inbox so it is not empty.
  • Thank-you: a light ask for a photo or review after payment. Keep scripts off the payment steps.
Hub page sketch: rating summary, recent photo reviews, link back to top products.

QA checklist before you publish

SurfacePass looks like
App embedEmbed on; no console errors on the PDP
Stars under titleAverage and count match the review list for that product
Review listBodies and photos visible without a second click maze
Structured dataValidator passes; no second AggregateRating from another app
Reviews hubPage loads, lists recent reviews, linked from footer
Q&AAt least two seeded answers; ask box works while logged out
Thank-you blockShows after a test order; no checkout payment-step scripts
MobileStars and ask box reachable with one thumb
Empty productProduct with zero reviews shows no fake 5.0 aggregate
Check on a real phone and on desktop. Fix red rows before publish.

Run a sample URL through the review schema validator after the stars block is on.

What this afternoon is not

This is not a tour of every Shopify reviews app. Switching apps mid-afternoon resets theme work you already owe yourself. Finish the blocks on the stack you have. Compare vendors later with a clear list of surfaces you already run.

Questions merchants ask

  • Do I need Shopify Plus for thank-you review blocks?

    No. Thank you and Order status app blocks are available below Plus. Payment-step checkout extensions are the Plus-gated surface.

  • Should I enable review JSON-LD on every product?

    Enable it where first-party product reviews are visible. Omit aggregates on products with no rated reviews. Do not mark up imported third-party scores.

  • What if I already use Judge.me stars?

    Keep one markup source. Judge.me can stay as collector and Google submitter. Decide how theme blocks share the page. Avoid double AggregateRating.

  • How long should seeding Q&A take?

    Two to five answers from last week's support macros is enough for the afternoon. Expand after publish.
