Plug In SEO vs SEOLab: Which Shopify SEO App Is Right for You? (2026)

We build Plug In SEO, so weigh that against everything below. Every price, rating, and feature comes from each app’s live Shopify App Store listing as of August 2026. None of it is from memory. SEOLab: All in SEO — AI SEO, built by Commerce Plus, is a genuinely well-reviewed app. It has 2,338 reviews and a fully free listing, with no paid tier surfaced anywhere on the page. It’s a serious option worth comparing honestly, AI product descriptions and AI-visibility tracking included.

The short answer

SEOLab vs Plug In SEO, side by side on the Shopify App Store

Pricing, ratings, and features as listed on the SEOLab Shopify App Store page and Plug In SEO’s own listing, August 2026. Check each listing directly — both apps update pricing and features periodically.

Where SEOLab pulls ahead

The bottom line: SEOLab packs technical automation, AI content generation, and cross-platform visibility tracking into one subscription — and charges nothing for any of it.

A free plan with almost everything included

SEOLab’s listing shows no paid tier at all. The free plan covers meta tag, alt text, and JSON-LD automation. It also handles broken-link detection with bulk redirects, image compression and lazy loading, robots.txt management, and 404 handling. Local SEO, bulk editing, keyword analysis, and rank tracking round it out. It even carries Shopify’s Built for Shopify badge — the same standard Plug In SEO meets on its paid plans.

AI product descriptions and AI-visibility tracking

SEOLab’s listing names a feature to “instantly create SEO engaging, high-converting product descriptions” using AI, generated in bulk across the catalog. Plug In SEO doesn’t generate AI content at all. Its Keyword Studio suggests AI-drafted copy per page, but a person approves or rejects it before it goes live. Bulk, hands-off AI writing is a different job. Our sibling app, Plug In AI, does that instead. It writes titles, descriptions, alt text, and meta, in your store’s own voice.

SEOLab also markets visibility tracking across “Google, ChatGPT, Gemini, and more,” plus llms.txt support. That’s the same GEO/AEO territory we care about. Whichever tool writes your product copy, the same publishing standard applies:

That’s not a knock on SEOLab specifically — it applies equally to Plug In AI’s bulk output or any AI writer. Review what gets generated before it goes live, whichever app is doing the writing. For more on what “AI SEO” does and doesn’t mean for a Shopify store, see our full breakdown.

The llms.txt claim

SEOLab’s llms.txt support sits in the same category as similar claims from other SEO apps we’ve reviewed:

SEOLab sells a real, named llms.txt feature, and we’re reporting that honestly. Whether it moves the needle on AI visibility is a separate question. No vendor, including us, can currently answer that with confidence. Structured data and genuinely useful content remain the mechanism Google has actually confirmed.

Where Plug In SEO pulls ahead

The bottom line: Plug In SEO trades SEOLab’s automate-everything scope for a narrower, human-reviewed loop — every suggestion explained, every change approved, every result tracked against real Search Console data.

A reviewed workflow, not blanket automation

Keyword Studio works page by page. Auto-research pulls keyword ideas from Search Console and the web, while “generate new ideas” scans the page’s own content. Expert mode lets you add any keyword manually. Each suggested keyword shows priority, match status, volume, and competitiveness before you use it. The AI drafts updated copy with its reasoning attached, but you approve or reject each change — it doesn’t auto-publish across your catalog. The SEO Scanner works the same way. It flags heading structure, missing schema, and content gaps, and a support link explains how to fix each one.

Rank tracking that tells you if it worked

Plug In SEO connects to Google Search Console and shows top pages, rankings, position, and click-through rate inside the app. Issues get color-coded red, yellow, and green, so you know what to fix first. That closes a loop SEOLab’s automation skips. You can see whether a change actually moved a ranking, not just that a change was made. Every plan also adds Product, Article, WebSite, Organization, Social, and BreadcrumbList schema automatically. Weighing a similar trade-off against a different app? Our Plug In SEO vs SearchPie comparison covers another angle of it.

The honest trade-offs

On price and scope: SEOLab genuinely costs nothing. It already covers AI product descriptions, cross-engine visibility tracking, image and speed work, and bulk technical automation. Plug In SEO splits some of that into a separate app (Plug In Speed handles images and speed). The rest, it charges for from day one, with no free plan at all.

On AI content specifically: SEOLab writes product descriptions in bulk, automatically. Plug In SEO doesn’t do that at any price. Plug In AI is the app that does, as a separate install with its own tone settings. If bulk AI copy across your catalog is the gap you’re filling, weigh SEOLab against Plug In AI, not against Plug In SEO.

On automation versus control: SEOLab scales by acting on your store directly — tags, meta, JSON-LD, and product copy all update automatically. Plug In SEO adds a step SEOLab’s listing doesn’t offer. It shows you the fix, explains why it matters, and waits for your approval before tracking whether the ranking moved. That explain-then-verify step is the reason to pay for Plug In SEO. It’s not that SEOLab is a lesser app — it optimizes for hands-off speed, where Plug In SEO optimizes for a human checkpoint.

How to choose between Plug In SEO and SEOLab

Strip away the feature lists and it comes down to your actual bottleneck:

• “I want a free app that handles meta tags, JSON-LD, broken links, and AI product copy automatically.” → SEOLab’s free plan covers this well.
• “I want cross-engine AI visibility tracking bundled with technical SEO, at no cost.” → SEOLab is built for exactly that.
• “I don’t want anything published to my store without reviewing it first, and I want an app that explains every issue in plain English.” → Plug In SEO’s guided audit-and-approve workflow.
• “I want rank tracking tied to Google Search Console, so I know if a fix actually worked.” → Plug In SEO’s dashboard.
• “I want bulk AI-written product copy specifically.” → Neither SEOLab nor Plug In SEO alone is the whole answer here — compare SEOLab against Plug In AI, our bulk-content app, directly.

The honest summary: SEOLab is a legitimate, well-reviewed pick if you want one free app that automates meta tags, redirects, AI product copy, and visibility tracking. If your gap is a reviewed workflow with rank tracking that proves a fix worked, that’s what Plug In SEO’s $29.99/month starting price is paying for.
