12 Best Shopify SEO Apps in 2026: Free and Paid Apps Ranked

Avada is the best all-round pick in this list because the free plan is a working tool, not a demo: 100 image optimizations, 20 on-page audits and 100 AI credits every month. The Pro plan adds unlimited image optimization and audits, bulk meta tags, structured data and 1,000 AI credits, which covers the everyday SEO work of a growing store in one subscription.

The trade-off is price. At $34.95 a month, Pro is the second-priciest entry here, and the trial caps image compression at 100 images, so you cannot test the unlimited tier before paying. If your store has hundreds of products and you want one app to handle them, start here; if you only need schema or images, a cheaper specialist does the same job for less.

Tapita is the budget pick: the free plan covers on-page audits and 900 image compressions a month, and the $9.99 Basic plan adds 150-page audits, 100 image optimizations a day and 100 AI metadata credits. It also bundles LLMs.txt and page-speed tools, so one install covers Google rankings and AI search visibility at the same time.

The catch is the surcharge. Tapita adds $5 a month on Shopify Grow, $30 on Advanced and $60 on Shopify Plus, and extra audit pages and AI credits cost more on top. A store on a higher Shopify plan can end up paying twice the headline price. Check the full cost on the listing before you install, and compare it against the flat-priced apps here.

TinySEO started as an image optimizer and grew into a broad SEO app, and images are still its strongest job. The $14 Beginner plan covers 1,500 image optimizations a month with lazy loading, plus AI meta tags, JSON-LD and broken-link redirects. For a store with hundreds of product photos, that is the cheapest route to faster pages and cleaner image SEO.

The pricing follows your image count, so a large catalog pays $23 or $49 a month, and the free plan's 50 optimizations a month will not last a week on a big store. There is also no keyword research or rank tracking, so you still need another tool to decide what to rank for. Pick TinySEO when slow, heavy images are the problem; pick an all-in-one suite when the problem is content.

Yoast SEO is the only app here from a company that does SEO full-time, and it shows in the guidance: traffic-light checks for SEO and readability, AI suggestions for titles and descriptions, and automated structured data, all for $19 a month. It also bundles the Yoast SEO Academy, so a beginner learns the reasoning behind each fix instead of just following orders.

It is also the narrowest app in this list. There is no free plan, no site audit, no bulk image tools and no rank tracking — Yoast guides your content, it does not fix the store for you. Merchants rate it 4.3 out of 5, the lowest score here, mostly because the guidance can feel strict. Buy it for the teaching; buy an all-in-one suite for the automation.

SearchPie is the most guided app in this list. Its health reports list every SEO issue across the store, and bulk tools fix meta tags and alt text from templates or AI, with auto rich snippets adding JSON-LD for products, breadcrumbs and FAQs. The 24/7 SEO expert support is the safety net: when a fix is unclear, a person explains it.

That guidance costs $39 a month, the highest starting price here, and the free plan is basic enough that most stores will need Premium quickly. The AMP and speed tools are bundled in whether you want them or not. SearchPie fits a beginner who wants a person to call on; a confident store owner gets the same fixes cheaper from Tapita or Avada.

Smart SEO is the value pick for stores that sell in more than one language. The $14.99 Pro plan covers JSON-LD structured data, bulk tag editing and automation, and multilingual SEO starts on the $24.99 Business plan — the cheapest multi-language option in this list. Merchants rate it 5.0 out of 5, and reviews single out support for solving tricky schema and migration problems.

Watch the old prices. Several guides still quote $9.99 as the starting price, but the live listing starts at $14.99, and the AI search tools are new enough that long-term results are unproven. The free plan is also basic — JSON-LD and bulk editing need Pro. For a single-language store, TinySEO or StoreSEO cover the same ground for the same money.

StoreSEO is built for small stores: the free plan covers 25 products with one-click schema, and Lite costs $14.99 a month for 100 products with instant indexing requests, Search Console and Analytics built in. Its standout feature is the MCP connector, which lets Claude or ChatGPT edit your store's SEO directly — no other app here offers that.

The pricing follows your catalog, so a store past 250 products pays $249.99 a month for Advanced, which makes it the most expensive app here at scale. There is no keyword research or rank tracking either. StoreSEO is the right pick under 100 products; once the catalog grows past a few hundred, the flat-priced apps like Tapita and Avada cost less.

SEOWILL, formerly SEOAnt, is the content pick in this list. The $29.99 Pro plan pairs AI-written blog posts and keyword plans with image compression, speed tools, bulk meta editing and JSON-LD, so one subscription covers both the technical fixes and the content that earns rankings. The free plan includes a full site scan, 50 image compressions and 30 AI credits a month.

Two honest caveats come from the app's own listing. The audit can show stale findings because full re-scans are manual, and uninstalling can leave speed snippets in your theme that need manual cleanup. AI credit overage is also a separate toggle that can bill beyond the plan. If you want AI content with your SEO, SEOWILL is the pick — just check the overage toggle first.

Plug in SEO has been on Shopify since 2011, longer than any other app here, and it shows in the depth: guided audits, AI keyword research, rank tracking, broken-link redirects and structured data in one app. The step-by-step guidance and code snippets mean a store owner can fix most issues without hiring an agency, which is the point of the app.

The catch is that there is no free plan — Lite starts at $29.99 a month after a 14-day trial — and Lite scans only 200 pages, so larger stores need Standard at $49.99 or Premium at $79.99. Merchants rate it 4.6 out of 5, below most apps here. It fits a DIY owner who wants keyword research bundled in; pure fixers cost less.

SEO Manager is the monitoring pick: the $9 Starter plan is the cheapest paid entry in this list, and it watches the store continuously with SEO scoring, broken-link tracking and 404 redirect management. It also handles structured data and IndexNow, so new and changed pages reach search engines faster without manual submission.

There is no free plan, so the 7-day trial is the only test before paying, and some reviewers say the $9 Starter plan feels thin and pushes upgrades. Keyword research and content planning are also limited — this app monitors and fixes, it does not plan what to write. Pick it when you want a watchdog for a live store, not when you need content ideas.

SEO King is the bulk-editing pick: paid plans start at $9.99 a month and include unlimited GPT AI for bulk content and image work, while the free plan already covers bulk alt text, meta titles and descriptions. For a large catalog that needs the same fix applied to hundreds of products, that combination is the most automation per dollar in this list.

The pricing needs a careful read. Some premium AI services, including translation and image upscaling, cost extra, and reviewers note the mix of subscriptions and one-time fees can hide the true cost. It also has fewer reviews than the leaders here. If your catalog is large and your budget is small, SEO King is worth the trial — just read the plan page first.

Webrex does one job and does it well: structured data. The free plan includes unlimited product schema plus organization, breadcrumb and local business markup, and Growth costs $9.99 a month to add review schema from Judge.me and 35+ other review apps. Merchants rate it 4.9 out of 5 from 844 reviews, with support praised for fixing schema conflicts fast.

It is a specialist, not a suite: there are no audits, keyword tools or image optimization, so you will still need another app for those jobs. Duplicate schema cleanup and rich-result monitoring also need Pro at $29.99 a month, and the star-rating feature is a separate premium tier. Buy Webrex when rich results are the goal; buy an all-in-one when the whole store needs work.
