SEOLab vs Smart SEO: Free All-in-One or $14.99 to $49.99 a Month?

SEOLab is the better choice for most Shopify stores in 2026 because it includes for free what Smart SEO spreads across a free plan and Pro ($14.99), Business ($24.99), and Premium ($49.99) tiers. SEOLab gives you bulk meta tags, JSON-LD, alt text, image compression, and auto fix for broken links with no image or AI generation quotas. Smart SEO is a mature, well reviewed app, rated 5.0 from 954 reviews, with a low paid entry price and strong support, so it deserves a fair look. Here is how they compare.

Disclosure: SEOLab is our app. To keep this fair we compared both against their live Shopify App Store listings and public product pages on 2 October 2026, cited dated merchant reviews, and gave Smart SEO a section of its own. Smart SEO's own product page and listing are the source for every Smart SEO price and quota below, and third-party roundups were not used.

SEOLab vs Smart SEO: What Are the Key Differences at a Glance?

Ratings come from the live SEOLab listing and Smart SEO listing. SEOLab is free at the time of writing, and independent reviewers note the team plans paid tiers later, so check the listing before you commit long term. Smart SEO's listing name is Smart SEO AI & Image Optimizer, and the developer, Sherpas Design, is based in Sofia, Bulgaria.

What Does Each Plan Really Include?

Smart SEO sells four plans on its Shopify listing, and each paid plan has a 7 day free trial. Here are the plans side by side with SEOLab.

Annual billing brings Business to about $250 and Premium to about $500 a year. For a store that needs automatic broken link fixing and the highest quotas, that is the price of Premium, before any usage-based charges.

Which App Handles Meta Tags and AI Generation Better at Scale?

Smart SEO's Free plan includes meta tag and alt tag optimization, and bulk editing starts on Pro. Its AI writing is metered. The Sherpas product page lists 20 AI generations on Free, 200 on Pro, 500 on Business, and 1,200 on Premium, with unlimited generations on Premium if you connect your own AI key. The Pro column also lists extra AI generations at 10 cents each, extra audit pages at 1 cent, and extra images at 1 cent, and the listing says usage-based charges are billed every 30 days. SEOLab handles this in Page Optimization: a scan scores every product, collection, blog, and page, then shows a focus keyword, an SEO score, and an AI Optimizer button per row, with no generation meter.

• Coverage: both apps reach products, collections, blogs, and pages, and SEOLab adds the home page as its own tab.
• Control: SEOLab shows the score and the suggestion before you apply. Smart SEO adds AI bulk optimization on Business, which is faster but touches many pages at once, so preview a sample first.
• Cost: on Smart SEO, regenerating a description you dislike uses another generation. On SEOLab the AI Optimizer is included.

For the mechanics of a good title and description, see our meta titles guide and the Meta Title and Description Optimizer page.

How Do They Compare on Technical SEO and JSON-LD Schema?

Technical SEO covers the code layer: JSON-LD schema, canonical and robots handling, sitemaps, and URL structure. Smart SEO's Free plan includes a sitemap and NoIndex tags, and it lists JSON-LD on Pro at $14.99 a month. Reviewers praise its multilingual JSON-LD, which matters if you sell in several store languages.

SEOLab includes JSON-LD in the free install, alongside a Search Appearance section, a URL handle and slug manager, and a robots.txt customizer. The most common schema problem on Shopify is duplicate Product markup from a theme, a reviews app, and an SEO app together. A September 2026 Smart SEO reviewer describes support tracing exactly that to their theme and Judge.me, so test a product URL in Google's Rich Results Test after enabling schema in any app, and read our JSON-LD guide for the fix.

Which App Fixes Broken Links and Redirects Better?

This is where the free-versus-paid split shows up again. Smart SEO finds on-site broken links by crawling and records visitor 404 hits, and per its broken links guide you can fix links one by one or in a selection by redirecting them, with the homepage as the default target. Automatic fixing by rules for products, collections, blogs, articles, and pages sits on Premium at $49.99 a month, and the Free plan checks 100 links. SEOLab's URL Management includes a toggle for auto fixing broken links, which monitors new 404s and redirects them to a target URL you set, plus a Broken Links Finder, manual redirect creation, and a Link Monitor with Unresolved, Manage Redirects, and Ignored queues.

One caution applies to both: an automatic rule that sends every 404 to one target is triage, not strategy. Send high value URLs to a relevant page. Our broken links and redirects playbook explains why, and the Broken Link Redirects page shows the full workflow.

What About Indexing, Sitemaps, and IndexNow?

Getting new pages discovered quickly matters most for stores that launch products often. Smart SEO lists IndexNow and Google Search Console integration on Pro, and its sitemap and indexing controls start on the Free plan. SEOLab's Sitemap and Indexing Manager generates a sitemap where you choose which products, collections, pages, and posts to include, submits important URLs directly, connects to Google Search Console, and keeps a submission history. Its optional GPTLab companion adds IndexNow.

Set expectations on both. IndexNow's FAQ lists Amazon, Bing, Naver, Seznam.cz, Yandex, and Yep as participating engines and does not list Google, and it says submitting a URL does not guarantee indexing. For Google, your sitemap and Search Console are what count. See the tool at Sitemap and Indexing Manager, and Smart SEO's own explainer on why Google does not index some pages.

Which App Is Better for Image Optimization?

Smart SEO optimizes 50 images on Free, 1,000 on Pro, 3,000 on Business, and 5,000 on Premium, with compression and backup, AI-generated alt text, and bulk editing of alt text, filenames, and compression. Filename optimization and AI bulk filename work sit on Business. SEOLab puts alt text and compression in one place: an Alt Tags tab with a Fix all alt text button, and an Image Optimization tab that reports images optimized and average size saved.

• Alt text: both cover it, and Smart SEO adds AI generated alt text inside its generation quota.
• Compression: Smart SEO is capped by plan. SEOLab is not capped.
• Safety: Smart SEO lists image backup. Keep your own copy of product images before any bulk compression, on any app.

Image work is often the largest speed win on a store, so see our image optimization guide and the Image Compression page.

How Do the Audits and Focus Keywords Compare?

Smart SEO's audit scans 20 pages on Free, 200 on Pro, 500 on Business, and is unlimited on Premium. According to its audit tool article, it checks title length, focus keyword placement, description length, alt tags, and handle length, lets you edit product fields inside the audit, and uses the product title as the default focus keyword. Sherpas is candid that the score is internal and that Google does not see or use it, which is the right way to treat any SEO score.

SEOLab's SEO Audit and Site Health scans the home page, products, collections, and blogs, and returns an SEO health score and separate mobile and desktop speed scores. A prioritized Do These Next list turns findings into actions, and the dashboard includes competitor comparison for SEO and speed. See the SEO Audit and Site Health page.

How Do They Handle AI Search, LLMs.txt, and MCP?

Both apps lean into AI search. Smart SEO lists LLMs.txt and Agents.md catalogues, Google Search Console integration with MCP and Sidekick, and a Model Control Protocol server for AI agent insights, all from Pro. SEOLab's AI Visibility section includes LLMs.txt and Agents.md on the built-in plan, and the GPTLab option adds LLM citation tracking, competitor analysis, prompt testing, IndexNow, and AI traffic monitoring.

Keep the claims in proportion. Google's AI features documentation says there are no additional requirements to appear in AI Overviews or AI Mode, and that you do not need new machine readable files, AI text files, or special markup. Neither app can guarantee a mention in ChatGPT. Our AI SEO guide explains what actually moves citations.

What Should Merchants With Large Catalogs Know?

Catalog size turns plan limits into a pricing decision. Consider a store with 2,000 products, 2,000 product images, and AI descriptions for every product:

Smart SEO's overage pricing offers another route. At the 10 cents per generation listed in the Pro column, the 1,800 generations beyond Pro's 200 would add about $180 to a single month, so for a large one-off job it can cost more than Premium. Bulk meta templates cost no AI generations, but the AI writing is where quotas bite. For catalogs past a few hundred products, uncapped bulk tools are the deciding factor.

What Do Merchants Say About Each App?

Smart SEO holds a 5.0 rating, with 97 percent of its 954 reviews at five stars and five at one star. Its newest reviews, in August and September 2026, repeatedly name support agents Ivailo and Todor, praise multilingual JSON-LD and image compression, and call it good value. The critical reviews tell a fuller story, so here are the patterns on Smart SEO's review page:

These are individual reports against 954 reviews, so most merchants are satisfied, and the recent feedback is warm. They still support the same practical advice for any SEO app: check billing before you approve a plan, keep one SEO app active, and verify a live page after changes.

How Do You Switch From Smart SEO to SEOLab Safely?

Final Verdict: Which App Should You Choose?

Across meta tags, JSON-LD, broken links, indexing, images, audits, and AI search, SEOLab covers the same ground as Smart SEO's Pro, Business, and Premium tiers at no cost, and without image, audit, or AI generation quotas or usage-based charges. That matters most on large catalogs, where 2,000 images and 2,000 AI descriptions push Smart SEO to its $49.99 Premium tier. Its scan-and-approve workflow also lets you review changes before they touch your store. That makes SEOLab the stronger pick for most merchants, and the clear pick for large catalogs and budget conscious stores.

Smart SEO remains a credible option if you value hands-on support, want to run AI generation on your own key, or want a long-established app, and you are comfortable paying $14.99 to $49.99 a month. Whichever you choose, do not stack two SEO apps, and verify results in Google Search Console after any change.
