10 Best Shopify SEO Apps of 2026

Smart SEO from Sherpas Design has been on the Shopify App Store since August 2015, and its plan ladder is the easiest to justify on this list. The free plan covers meta tag and alt tag optimization, a sitemap, noindex tags, a broken link check on 100 pages, 50 image optimizations, 20 AI generations and an automatic audit of 20 pages. Pro at $14.99 a month, or $149.90 a year, adds JSON-LD, IndexNow and page speed tools, bulk meta and alt tag optimization, bulk image optimization, 404 hit detection and llms.txt and Agents.md files for AI assistants. Business at $24.99 adds AI bulk work on filenames, meta tags and alt tags, backlinks and multi language support, and Premium at $49.99 removes the audit cap. The trade-off is that the AI bulk features most stores want sit one tier above Pro. Merchants rate it 5.0 from 960 reviews.

Booster SEO, listed as Booster AI SEO + AEO Optimizer, is the most reviewed app in this group, with 5,489 merchant reviews and a 4.8 rating in November 2026. It has been on the Shopify App Store since March 2016. The free plan gives an SEO score and health badge, alt text optimization with custom templates, broken link detection and reporting, manual audits, weekly sync for 50 images, weekly email reports and 24/7 chat support. Pro at $39 a month, or $349 a year, is where the automation starts: meta title and description optimization, templates for every meta tag, autopilot fixes and monitoring, automatic broken link fixes, Google rich snippets and structured data, sitemap submission and preparation for ChatGPT and AI search. Premium at $69 adds image compression with 5GB a month, URL keyword optimization, image filename SEO and 365 days of Search Console metrics. It costs more than Smart SEO for similar features, so the case for it is automation and its track record.

TinySEO is the app many merchants still know as TinyIMG; the developer now lists itself as TinySEO (former TinyIMG) and the app has been on the Shopify App Store since June 2019. Its pricing is built around image volume. The free plan includes 50 image optimizations a month, alt text and filename optimization and a 30-day image backup. Beginner at $14 a month, or $140 a year, raises that to 1,500 optimizations and adds image resizing, JSON-LD for return policy and shipping details, site audits with automated fixes, lazy loading, asset preloading and an AI blog builder. Advanced at $23 adds IndexNow, broken link detection and redirects, automatic AI metadata, CSS and JavaScript minification and llms.txt editing, and Expert at $49 adds 15,000 optimizations and extended JSON-LD. Overage is billed per image, from 2 cents down to 0.8 cents. Merchants rate it 5.0 from 2,587 reviews, and it is the most direct pick when large product photos are slowing the store.

Avada SEO, listed as Avada AI SEO Image Optimizer, launched in April 2020 and showed a 4.9 rating from 4,692 reviews in November 2026, the second largest review base here. The free plan is generous: 100 image optimizations, a basic speed booster, an HTML sitemap, meta tags, 20 on-page audits with 100 AI credits, basic Google structured data and an image alt text optimizer. Pro at $34.95 a month, or $348 a year, makes image optimization and on-page audits unlimited, raises AI credits to 1,000 and adds a turbo speed booster, pro structured data, a broken link manager with URL optimization, an XML sitemap generator, a robots.txt editor and AI alt text. Enterprise at $99 adds consulting, an AI audit agent with 10,000 credits and advanced structured data. The gap between the free plan and $34.95 is wide, with no cheap middle tier, so it fits stores that will use unlimited audits rather than those that want a $10 to $15 upgrade.

SearchPie, listed as SearchPie: AI SEO & Schema by PieLab, has been on the Shopify App Store since July 2019 and showed a 4.9 rating from 2,459 reviews in November 2026. Its free Starter plan does more than most: an SEO health and AI readiness score, breadcrumbs and store schema, a sitemap, image compression, CSS minification, bulk meta tags and alt text with templates, AI SEO and alt tags, an LLMs.txt file, IndexNow and 404 detection across all pages. Premium adds price, rating, in-stock and FAQ schema, JavaScript minification, lazy loading, automatic tag optimization, AI product descriptions, automatic 404 fixes and backlink submission. Enterprise adds sitelink and article schema, unlimited image compression, keyword research and tracking and 5,000 AI SEO tags. In November 2026 the listing showed Premium at $19.50 a month for the first 3 months, then $39, and Enterprise at $49.50, then $99, as a Black Friday offer. Plan on the regular prices.

Plug in SEO, now listed as Plug in SEO: SEO Audit & Fix, is the oldest app here, on the Shopify App Store since June 2011. It is built around scanning: the app checks pages for missing tags, broken schema and other issues, then lets you fix alt text, file names, URLs and meta tags in bulk. Starter at $4.99 a month is the cheapest paid plan on this list and includes a scan of up to 30 pages, AI keyword research for 2 pages, one monthly audit, JSON-LD tools, one-click broken link redirects and search trend analytics. Lite at $29.99 raises the scan to 200 pages and adds title and description management and bulk AI edits. Standard at $49.99 covers 2,000 pages with a 30-minute expert call, and Premium at $79.99 is unlimited. The 30-page cap on Starter only suits very small stores, and there is no free plan. Merchants rate it 4.6 from 678 reviews.

SEO Manager by venntov launched in May 2012 and is one of the longest running SEO apps on Shopify. It positions itself as SEO infrastructure: managing metadata across products, collections, pages and blog posts, structured data, product catalogs, broken links and 404 redirects, with IndexNow for faster indexing. Starter at $9 a month includes SEO monitoring and scoring, a simulation of how pages appear in Google results, image and page optimization, structured data testing and missing page and broken link tracking. Essential at $29 adds enhanced scoring and reporting, advanced meta tag control, out of stock redirects and automated broken link management. Professional at $59 adds AI broken link handling, automated enhancements, AI content generation, an HTML sitemap and advanced Google integration. There is no free plan and the interface is English only, and the AI features cost more here than in Smart SEO. Merchants rate it 4.6 from 488 reviews.

Schema Plus, listed as Schema Plus: AI & SEO JSON-LD, does one thing: it adds structured data so Google and AI assistants can read product, price and review details. It has been on the Shopify App Store since November 2018. Lite at $10.99 a month covers up to 5 product and review schemas and works with AliExpress, Judge.me, Junip, Loox, Okendo, Reviews.io, Ryviu, Stamped.io and Yotpo reviews. Essential at $17.99 covers up to 250 schemas and adds organization, blog, collection, store page, search box and breadcrumb schema. Premium at $28.99 is unlimited and adds a Search Console performance report, merchant listings, shipping and return policy, local business, video, recipe and FAQ schema. Every plan includes 24/7 chat and a free setup call. It has no meta tag, image or speed tools, so most stores pair it with an SEO suite and switch off that suite's schema module. Merchants rate it 4.9 from 592 reviews.

JSON-LD for SEO, listed as Ilana's JSON-LD for SEO, has been on the Shopify App Store since October 2015 and is sold as a single Annual Pro plan at $399 a year. That works out to about $33 a month, paid up front. The app adds expanded schema.org markup for products, reviews, blogs, breadcrumbs, the homepage, loyalty programs, recipes, FAQs and video, and connects the schema fields Google Merchant Center needs with or without a product feed. It supports more than 20 review apps, can be customized for preorders, product condition, subscriptions and minimum quantities, and includes ongoing rich results monitoring, a structured data audit and an SEO video course. Like Schema Plus, it has no meta tag, image or speed tools. The annual-only price is the main barrier for a new store, but there are no schema caps or tiers. Merchants rate it 4.9 from 442 reviews.

Yoast SEO brings the analysis panel many WordPress users know to Shopify; the app launched in September 2021. It works inside the product editor, scoring each product for SEO and readability and suggesting meta titles and descriptions with AI. Yoast SEO Premium at $19 a month, or $190 a year, includes SEO and readability analysis, automatically added structured data, technical SEO improvements such as llms.txt generation, a bulk editor with import and export and 24/7 support. Yoast SEO AI+ at $45 a month, or $450 a year, adds an AI Visibility Index with sentiment analysis, competitor benchmarking and citation and source tracking for AI assistants. What it leaves out matters: there is no image compression, broken link handling or speed tooling, so a store would still need another app for those. Its listing showed a 4.3 rating from 173 reviews, the weakest score and smallest review base on this list.
