## Ways to pay less

- **Save up to 52% with yearly billing** (Annual discount): The listing offers the 500-page tier at $69.99 a year (42% off), 5,000 pages at $79.99 (52%) and 20,000 pages at $99.99 (51%). Source: https://apps.shopify.com/seo-king

## Key features

- **Unlimited AI meta text:** Paid plans write meta titles, meta descriptions, alt text and product descriptions with GPT and Gemini models, with no credit limit, and can keep them updated.
- **Image optimization:** Compresses, resizes, converts and renames photos without a meter. Vision AI alt text from the photo itself is pay-per-use, about $1 per 400 photos.
- **Store scan and SEO checklist:** Scans the store for SEO issues on every plan and lists fixes in a checklist and dashboard; changes can be previewed before they go live.
- **JSON-LD, sitemaps and robots.txt:** Advanced JSON-LD schemas including FAQ markup, image sitemaps, and robots.txt and llms.txt editing on paid plans.
- **Keywords and SERP rankings:** Google Search Console stats and site keyword analytics on every plan, with SERP rank tracking and a page tracker in the app.
- **Links, redirects and translation:** Finds broken links and 404 errors, manages redirects and URL rewriting, and writes SEO text in more than 40 languages.

## Good for

- Shopify stores that want AI-written meta tags without counting credits
- Large catalogs, since the 20,000-page tier is $16.99 a month
- Merchants who want one app instead of separate image, schema and redirect apps

## Worth knowing

- Works only on Shopify stores; it is installed from the Shopify App Store.
- AI text, auto-updating, bulk photo work, robots.txt, llms.txt and advanced JSON-LD all need a paid tier; tiers differ only in pages covered.
- Vision AI, translation, upscaling and background removal are paid per use from prepaid credits, or by an optional unlimited AI credits plan.
- A done-for-you Full-Service tier with expert setup and monthly strategy calls costs $95 a month or $595 a year, without theme work.

## ToolGPA grades

**GPA: 2.6 out of 4**, graded Oct 23, 2026. SEO King is a Shopify app that scans your store, edits meta tags and alt text, handles images, JSON-LD, redirects and sitemaps, and on paid tiers writes meta text with AI with no credit limit. Paid tiers start at $9.99 every 30 days for 500 pages. But the AI that reads your photos, translation and background removal cost extra from prepaid credits, and it only works on Shopify.

- **Value for money: C.** $9.99 every 30 days for up to 500 pages, a little above the $8.25 where this category's cheaper quarter ends. Yearly billing brings it to $69.99, about $5.83 a month, and the 20,000-page tier is $16.99 a month. Vision AI and translation cost extra.
- **Free plan and trial: B.** The free basics have no stated cap: alt text, meta title and description edits, photo renaming and compression, a store scan and Search Console stats. A small store could run on that. What's missing is any AI text, bulk photo work, robots.txt and llms.txt.
- **Features: B.** Store scans with a fix checklist, image compression, JSON-LD with FAQ markup, image sitemaps, robots.txt and llms.txt, broken links and redirects, rank tracking and SEO text in 40+ languages. Nothing in the listing leaves a gap in the job; tiers differ only in pages covered.
- **Ease of use: C.** No store rating on record. It installs from the Shopify App Store, but you connect Search Console, work through the checklist and choose what the AI rewrites and keeps updated.
- **Platforms and integrations: B.** Web, inside the Shopify admin, with Google Search Console, Google Merchant Center, Easy Watermarks and Swap Photo Editor, and AI writing through MCP. No phone or desktop app, and nothing for stores off Shopify.

## Keep it, or make your own?

**Keep it.** To replace SEO King you would be making search volumes for millions of keywords, gathered and kept up to date. That is not a weekend's work, with an AI app builder or without one. It costs $119.88 a year.

- You could make: Schema markup: an app builder makes this well.
- You could not: Search volumes for millions of keywords, gathered and kept up to date.
- You could not: A crawler that checks every page of a site.
- You could not: A score built from what the top results for each keyword cover.
- You could not: Daily checks of where your pages rank in search results.
- You could not: AI features, unless you pay a model provider for each request yourself.
- You could not: The depth: we grade its features B, which means it covers the whole job.

A judgement by ToolGPA from this listing, by rules that are the same for every tool. Nothing was built to test it.
