Reviews

Individual app breakdowns

Smart SEO

What it does well

  • Quick meta title and description templates for products and collections
  • Low cost entry for stores under 500 SKUs
  • Simple health dashboard for missing alt text and meta

Limitations

  • Template-only approach without collection hub strategy
  • Schema output can conflict with Dawn-based theme JSON-LD

Who it suits: Small UK stores that need baseline meta coverage before a full audit.

Plug in SEO

What it does well

  • Regular scan emails when titles or descriptions break after theme updates
  • Clear pass/fail style reports store owners understand
  • Good first step after migration to catch obvious metadata resets

Limitations

  • Does not fix filter URL indexation or app script weight
  • Alerts create noise if theme changes frequently without a dev owner

Who it suits: Merchants who want monitoring but will still need template-level dev for serious issues.

JSON-LD for SEO

What it does well

  • Adds Product and Organization schema when themes ship thin markup
  • Useful on older custom themes missing structured data

Limitations

  • Most common issue we see: duplicate Product graphs alongside theme or review apps
  • Requires validation in GSC after every app or theme update

Who it suits: Stores with no product schema today, after confirming the theme does not already output JSON-LD.

SearchPie

What it does well

  • Broad feature set: meta, schema, alt text, sitemap tweaks in one subscription
  • Helpful for teams without a dedicated SEO who need defaults fast

Limitations

  • Enabling every module increases script weight on mobile PDPs
  • Automation can mask underlying template problems

Who it suits: Mid-size stores with dev oversight to trim features and validate CWV after setup.

SEO Manager

What it does well

  • Bulk rules for titles and descriptions on large catalogues
  • Export and import workflows for agencies updating thousands of SKUs

Limitations

  • Bulk patterns like “{{ product }} | {{ shop }}” on every URL hurt differentiation
  • Does not replace category hub copy or internal linking strategy

Who it suits: Large Shopify catalogues with consistent naming rules and human QA on top sellers.

Honest limits

What apps cannot do

  • Fix faceted navigation index bloat without theme or filter app rule changes
  • Recover migration traffic from incomplete redirect maps
  • Remove duplicate schema when three apps inject Product JSON-LD
  • Write category hub copy that matches commercial search intent
  • Prioritise fixes against order data instead of crawl export volume
  • Replace Core Web Vitals work on heavy mobile product templates

App weight on PDPs: Shopify app bloat SEO.

FAQ

Do I need a Shopify SEO app at all?

Not always. Modern themes ship adequate meta fields and schema. Apps help when catalogues are large, metadata is inconsistent, or you need monitoring. They do not replace template, speed, and indexation work.

Why did our rich results break after installing an SEO app?

Usually duplicate Product schema from the app plus theme plus reviews widget. Validate one JSON-LD graph per URL and remove redundant outputs.
