A Shopify SEO app is an App Store extension that automates the jobs the platform doesn't do in bulk: alt text and meta tags across hundreds of products, extended structured data, image compression, bulk redirects. Shopify already handles sitemaps, canonicals, robots.txt and the title and meta description fields on its own, so a store with a few hundred products often doesn't need one, and when it does, one per job is enough.
On 10 October 2026 the SEO category of the Shopify App Store listed 1,165 apps.
The guides on page one of Google UK for "shopify seo apps" list anywhere from 10 to more than 20, and several date from 2023 and 2024. Most are ranked lists. We wanted to see what's actually in the code of UK Shopify stores.
Without that, the same thing keeps happening:
- people install an app to do what Shopify already does (sitemap, canonical), and pay for it every month;
- they install two apps that write the same structured data, and the product page ends up describing the same product two or three times;
- they choose by the stars, which in the SEO category are almost all the same (we'll get to the numbers shortly).
We see it on the Shopify stores we work on.
Scovaventi, an Italian food producer, had a store with traffic but no sales: after the rebuild on Shopify it closed a year with €77,000 in sales and an average order value of €190.
Bosatta sells Vespa and Piaggio spare parts in four countries: €240,000 in sales in a year and 127 enquiries from dealers and workshops.
What does that have to do with SEO apps?
On a store in four languages the right question isn't "which SEO app" but "which app handles Italian, Spanish, French and German without duplicating pages". And on Shopify, the feed that brings in sales from Google Shopping is generated by an app that doesn't even appear in the SEO category: Google & YouTube.
Here you'll find:
- what Shopify does without any app, with the official documentation;
- our test on 24 product pages from UK stores that show up on Google, with what we found in the code;
- eight apps compared on price, rating and languages, with App Store data from 10 October 2026;
- how many apps to keep and how to remove them without leaving residue in the theme.
Let's start with what you shouldn't pay for.
What Shopify does without apps (and what you risk paying for twice)
Shopify generates the sitemap, robots.txt and canonical tags by itself, and for every product, collection, page and blog post it lets you write the title, meta description and URL. These are the things half the SEO apps put in their shop window as features.
Everything else depends on the theme or on your time.
The table sets what Shopify's documentation says against when an app really makes sense.
| Element | What Shopify does on its own | When you need an app |
|---|---|---|
| Sitemap.xml | Generated automatically, split into products, collections, blogs and pages, with sitemap files for each international domain | Almost never |
| robots.txt | Default file, editable through the robots.txt.liquid template | Never for the basic rules: Shopify itself warns that incorrect use "can result in loss of all traffic" |
| Canonical | The theme prints it with the canonical_url object | No: it was there on 24 product pages out of 24 in our test |
| Title and meta description | One field per item; if you leave it empty the theme uses the product name and the store name | Only to rewrite them in bulk on large catalogues |
| 301 redirects | Added by hand or imported from CSV, up to 100,000 (20 million on the Plus plan) | For migrations with wildcard rules, which Shopify's page doesn't cover |
| Product structured data | Depends on the theme | Only if the theme doesn't write it, or to add reviews and shipping |
| Image alt text | One field per image | To fill it in bulk: it was missing on 9 product pages out of 24 |
What about apps that write titles with AI?
Shopify has one of its own: Grow SEO. It suggests longer page titles and descriptions for products and collections. But it's in early access, "available only to certain merchants", shows up to 100 suggestions and works in English only.
For a UK store the language isn't the obstacle, access is. If you have it, try it before paying for an AI app.

What we found on 24 UK Shopify stores (test of 10 October 2026)
On 24 product pages from UK Shopify stores (for stores on every platform, see our test of ecommerce SEO tools), the canonical was always there and the meta description was missing only once. The problems were elsewhere: 7 titles over 60 characters, 9 pages with images missing alt text, 8 with the product described two or three times in the structured data and 3 with no product structured data in the HTML.
Here's the method, so you can repeat it.
We used DataForSEO to read Google UK results (desktop, 10 October 2026) for five product searches: coffee beans online, handmade scented candles, handmade silver jewellery, loose leaf tea online and buy extra virgin olive oil online. We checked 35 shop domains in those results (leaving out supermarkets, marketplaces, review sites and social networks) and kept the ones running on Shopify, identified through the public /products.json endpoint: 24 (one more didn't answer). For each we opened one product page and counted, in the HTML as served (without running JavaScript), the structured data blocks, the app extensions loaded and the basic checks. Shopify started answering 429 (too many requests) after a few dozen calls, so we spread the requests out over time.
| Product page check | Stores | Out of 24 |
|---|---|---|
| Canonical tag present | 24 | 100% |
| Meta description present | 23 | 96% |
| Only one product in the structured data | 13 | 54% |
| Product described 2 or 3 times in the structured data | 8 | 33% |
| No product structured data in the HTML (JavaScript not run) | 3 | 13% |
| Title over 60 characters | 7 | 29% |
| Images without an alt attribute | 9 | 38% |
| H1 missing or duplicated | 4 | 17% |
| App extensions loaded on the page (median) | 3.5 | from 0 to 9 |
What does this table tell us?
That on Shopify the technical side is already handled by the platform: the canonical was never missing.
What was missing was the part a person writes: titles up to 76 characters, one product page whose title was just the store name, another with no title tag at all, and images without alternative text.
Then there's the most interesting case.
On one of the eight pages with the product repeated, the structured data described the same product three times, spread over six JSON-LD blocks, with 4 app extensions loaded. That's the typical signature of a theme writing its own Product and one or two apps adding theirs.
Is it a serious mistake?
It isn't a penalty. But Google's structured data guidelines ask for markup that is "a true representation of the page content": three versions of the same product, perhaps with prices or availability updated at different times, are the quickest way to lose the stars and the price in your snippet without knowing why. How to check it and fix it is in our guide to structured data.
How many times does Google read the same product on your store?
You've just seen that on 8 stores out of 24 the product page described the product more than once, and that on 9 some images had no alt text. We check your product pages on the same points, tell you which apps to keep and which to remove, and what to fix by hand before you pay for another subscription.
Book a strategy consultationShopify SEO apps worth knowing: prices, ratings and languages
The most installed Shopify SEO apps cost between $9.99 and $39 a month on their first paid plan, almost all of them have a free plan with limits, and the number of interface languages ranges from one to 27. The table shows what the App Store listings said on 10 October 2026. Prices are in US dollars because that's how Shopify lists and bills them: none of the eight publishes a sterling price.
| App | Rating (reviews) | Free plan | First paid plan | Interface languages | Built for Shopify |
|---|---|---|---|---|---|
| SearchPie | 4.9 (2,444) | Yes | $39/month | 18 | Yes |
| Booster AI SEO + AEO | 4.8 (5,481) | Yes | $39/month | 10 | Yes |
| Avada AI SEO Image Optimizer | 4.9 (4,689) | Yes, 100 images | $34.95/month | 14 | Yes |
| Smart SEO AI (Sherpas) | 5.0 (956) | Yes, 50 images | $14.99/month | 20 | Yes |
| StoreSEO | 5.0 (759) | Yes, 25 products | $14.99/month | 11 | Yes |
| SEO King | 4.7 (542) | Yes | $9.99/month | 27 | Yes |
| Yoast SEO | 4.3 (177) | No, 14-day trial | $19/month | 1 (English) | Not shown |
| Ilana's JSON-LD for SEO | 4.9 (441) | No, 7-day trial | $399/year | 1 (English) | Not shown |
Three things the table doesn't show.
The suites do everything, and that's exactly the risk. SearchPie, Booster and Avada compress images, write meta tags, add JSON-LD and handle 404s. If your product page already has structured data (21 stores out of 24 in the test did), the schema feature should be switched off, not added.
Yoast on Shopify isn't the Yoast you know from WordPress. It has been on the App Store since September 2021, costs $19 a month, has 177 reviews with a 4.3 rating and is in English only. It makes sense if you write a lot on the store's blog and want the content analysis you're used to. On the technical side it doesn't add much to what Shopify already does.
Ilana's JSON-LD for SEO does one thing. $399 a year for structured data and nothing else. It's the choice when the theme doesn't write it properly and you don't want a suite that also touches images and meta tags.
Recommended reading: if your store runs on WordPress rather than Shopify, our comparison of the best CMS for SEO covers both. In the UK, Shopify runs 10.4% of .uk sites with a known CMS according to W3Techs, WordPress 57.3% (10 October 2026).
Why App Store stars won't help you choose (17 apps out of 20 at 4.9 or above)
In the SEO category of the Shopify App Store, the first 20 apps in the default order nearly all have the same rating: 17 out of 20 are rated 4.9 or 5.0, and 18 of the 20 have a free plan or are free to install (the other two offer a trial). Here, the rating doesn't tell them apart.
We counted them on 10 October 2026.
And there's a second figure: 15 of the first 20 apps have "AI", "AEO" or "GPT" in their name. Alt text generators, article generators, apps "for ChatGPT".
And the first app on the list isn't even an SEO app in the strict sense: it's Judge.me, a reviews app, with 48,322 reviews.
So what do you choose on?
On three questions, in this order:
- which job do I need taken off my hands (alt text on 2,000 images? redirects for a migration? schema the theme doesn't write?);
- does the app work in the languages I sell in, in the interface and in the text it generates;
- does it have the Built for Shopify badge, which comes with written performance rules (more on this two sections down).
"AI" apps and the llms.txt file (what Google says)
You don't need any special file or markup to appear in Google's AI Overviews and AI Mode: Google says so in its documentation on AI features in Search. In its own words: "You don't need to create new machine readable files, AI text files, or markup to appear in these features".
Put simply: an llms.txt file won't get you into Google's AI answers.
Yet six of the eight apps in the table (SearchPie, Booster, Smart SEO, StoreSEO, SEO King and Yoast) list it among their features.
So it's useless?
For Google, yes. For other assistants there's no equivalent documentation saying otherwise, so it remains a cheap bet, as long as it isn't the reason you pay for the app. What counts for AI answers is what counts for Search: product pages with real copy, readable prices and availability, reviews. If you're interested in the next step, agents that buy on people's behalf, we've written about it in agentic commerce.
Generated text has another catch if you sell abroad. A title written automatically by a model has to be reread line by line, and on 500 products in three languages the time saved shrinks fast. Of the eight apps in the table, six have an interface in ten languages or more; Yoast and Ilana's are in English only.
How many apps to install (and how to remove them without leaving code in the theme)
One per job. In our test the product pages loaded a median of 3.5 app extensions, with a maximum of 9, and every extension is extra code to download.
Shopify has written rules here. To get the Built for Shopify badge, an app must not reduce the storefront Lighthouse performance score by more than ten points.
Ten points out of a hundred.
That's the ceiling for a single app, not for the total. Three apps at the limit make thirty points.
And not every app has the badge: in our table it wasn't shown on the Yoast and Ilana's JSON-LD listings.
And when I remove it?
It depends on how it's built. Apps that use theme app extensions are removed from the theme automatically and completely when you uninstall them, again according to Shopify's requirements. Older apps that wrote directly into the theme files can leave orphaned snippets and structured data behind.
So, before uninstalling:
- save a copy of the theme (Online Store, Themes, Duplicate);
- export the redirects the app created, if it managed them rather than Shopify;
- after removing it, check a product page with Google's Rich Results Test: if the Product still shows up twice, the leftover is in the theme.
Speed is still where apps weigh most: how to measure it without being fooled by a score is in our guide to page speed.
Which SEO app to choose, store by store
The choice depends on two numbers: how many products you have and how many languages you sell in. Below a few hundred products in one language, Shopify with the fields filled in by hand is often enough.
| Situation | What you need | What to avoid |
|---|---|---|
| Fewer than 200 products, one language | No SEO app: titles, meta and alt text written by hand, plus a reviews app | $39/month suites for features Shopify already has |
| Catalogue of thousands of products | An app for bulk alt text and meta, in the language you sell in | Generated copy published without rereading |
| Theme that doesn't write structured data | A dedicated schema app, or the code in the theme | Two sources of Product on the same page |
| Store in several languages (the Bosatta case) | Languages managed by Shopify, with the platform's sitemap and hreflang | Translation apps that create copies of pages |
| Migration from another CMS | A redirect app with bulk rules, only for the migration period | Leaving it installed for years |
We won't name a reviews app. We'll tell you where to look: the reviews should appear in the product page code and not only in a widget loaded afterwards, and the app shouldn't add a second Product to the theme's.
What about Google Ads?
If you sell on Shopify and run Shopping campaigns, the app that decides how many of your products are on show on Google is the feed app. In Google Ads for ecommerce you'll find how we set it up, with the Scovaventi case: €20,000 of budget, €77,000 in sales.
Summary
Shopify does the sitemap, canonical and robots.txt.
Titles and alt text are yours to write, or to have written in bulk.
One Product per product page.
One app per job, with the badge and in your languages.
An llms.txt file won't get you into AI Overviews.
What the industry rarely says is that the most useful SEO app for many Shopify stores isn't in the SEO category. The first app on the list is a reviews app, and Scovaventi's sales from Google went through a feed generated by Google's own app. Before comparing ten suites, ask which piece of data the product page is really missing: nearly always it's copy written by someone who knows the product, and no app installs that.
If you'd like us to look at your store's product pages, we start from the eight checks in the table: it's the first step of our work on ecommerce SEO, and if the store needs rebuilding we handle the Shopify development too. Until next time!
Frequently asked questions
No. Shopify generates the sitemap, robots.txt and canonical tags on its own and has fields for the title, meta description and URL of every product. An app is useful when you need to do something in bulk that would take days by hand, such as writing alt text for thousands of images, or when the theme doesn't write product structured data.
It depends on the job you want off your plate. On 10 October 2026, 18 of the first 20 apps in the SEO category had a free plan or were free to install, but with different limits: Avada starts at 100 images, Smart SEO at 50, StoreSEO at 25 products. Choose by the limit that affects your catalogue and by the languages you sell in.
Yes, if they do different things. The problem starts when two apps, or an app and the theme, write the same structured data: in our test on 24 UK stores, 8 product pages described the product more than once. Keep one source for each job.
Yes. It has been on the App Store since September 2021, costs $19 a month with a 14-day trial, has a 4.3 rating from 177 reviews and is available in English only. It makes most sense for stores that publish a lot on their blog.
It depends on what the app did. Apps that use theme app extensions are removed from the theme completely; older ones can leave code and structured data in the theme files. Before uninstalling, duplicate the theme, export any redirects the app created, then recheck a product page with Google's Rich Results Test.
No. Google's documentation on AI features in Search says you don't need new machine readable files, AI text files or special markup to appear in AI Overviews or AI Mode. The same rules as traditional Search apply.
