Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.0
GPA, above 7 of the 78 other SEO plugins and apps we grade
Plug in SEO is a Shopify app that audits a store's pages for SEO problems and explains each fix, and many fixes can be applied in bulk with templates for titles, meta descriptions and alt text. It adds JSON-LD structured data automatically, finds and redirects broken links, and includes AI keyword research and AI-written titles and descriptions that you approve before they go live. There is no free plan.
To get you started, here are 9 things to know about Plug in SEO, taken from its own pages and our grades.
The audit explains each fix in plain English, but templates are written in Shopify's Liquid and every AI change waits for you to approve it.

The report card
Best for a Shopify SEO audit with steps for each fix
Plug in SEO audits a Shopify store, explains each problem in plain English and fixes many of them in bulk, with JSON-LD, broken-link redirects and keyword research on top. There's no free plan, and Lite at $29.99 a month only scans 200 pages and runs 2 full audits a month. Speed reports and the expert call start at $49.99.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | D | Lite is $29.99 every 30 days, nearly three times this category's $10.99 middle, and it scans only 200 pages with 2 full audits a month. Standard, with 2,000 pages and speed reports, is $49.99, well into the dearest tenth. No yearly price is listed. |
| Free plan and trial | C | No free plan, but every plan has a 7-day trial that needs no card. After that it's $29.99 a month at the least. |
| Features | C | Audits with fix steps, bulk alt text, URL and meta edits, Liquid templates, AI keyword research, AI titles you approve, JSON-LD and one-click redirects. The listing names no sitemap, image compression or llms.txt tools, and Lite's 2 audits a month is a real cap. |
| Ease of use | C | No store rating on record. The audit explains each fix in plain English, but templates are written in Shopify's Liquid and every AI change waits for you to approve it. |
| Platforms and integrations | B | Web, inside the Shopify admin, with Google Search Console, Bing, Judge.me, Langify and Locksmith. 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.

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 Plug in SEO 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.
That makes this kind of software worth paying for, not this one in particular: 61 of the 78 other SEO plugins and apps grade higher. It costs $359.88 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.
- It plugs into other products, Google Search Console, Bing and Judge.me among them.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. Plug in SEO’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.
