Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.6
GPA, above 49 of the 78 other SEO plugins and apps we grade
SEO King is a Shopify app that brings store scans, image optimization, JSON-LD, broken links and redirects, sitemaps, robots.txt and llms.txt editing, and Search Console analytics into one dashboard. Paid plans add unlimited AI writing of meta titles, meta descriptions, alt text and product descriptions, one at a time, in bulk or through MCP. Paid tiers are priced by the number of store pages covered.
To get you started, here are 9 things to know about SEO King, taken from its own pages and our grades.
- 1
Best for AI meta text on a Shopify store, priced by page count
But the AI that reads your photos, translation and background removal cost extra from prepaid credits, and it only works on Shopify.
- 2
Paid plans start at $9.99 a month
As its pricing page puts it: $9.99 per month for up to 500 pages, billed every 30 days.
- 3
There is a free plan
Free basics: unlimited alt text, meta title and meta description updates, photo renaming and optimization, a store scan, and Search Console and keyword analytics. No AI text.
- 4
It runs on Web
Web.
- 5
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.
- 6
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.
- 7
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.
- 8
A 2.6 GPA, above 49 of 78
That is against the other SEO plugins and apps we grade, on value, the free plan, features, ease of use and platforms.
- 9
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.

The report card
Best for AI meta text on a Shopify store, priced by page count
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.
| Subject | Grade | Comment |
|---|---|---|
| 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. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who SEO King is for
- Fits if you run a Shopify store and want AI meta text without counting credits
- Works for large catalogs, since 20,000 pages is $16.99 a month
Who it is not for
- Skip it if your store isn't on Shopify, as that's the only place it installs
- Tight if you stay free, because AI text, bulk photo work, robots.txt and llms.txt are all paid
- Watch out: alt text read from the photo itself is about $1 per 400 photos, and translation and upscaling also use prepaid credits
- Pricey if you want it done for you, as the Full-Service tier is $95 a month or $595 a year, with no theme work
Good to know
Good for
- Shopify stores that want AI-written meta tags without counting credits

- 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.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
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.
What you could make
- Schema markup: an app builder makes this well.
What you could not
- Search volumes for millions of keywords, gathered and kept up to date.
- A crawler that checks every page of a site.
- A score built from what the top results for each keyword cover.
- Daily checks of where your pages rank in search results.
- AI features, unless you pay a model provider for each request yourself.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. SEO King’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
