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

We build Plug In SEO, so weigh that accordingly — but every price, rating, and feature below comes from each app’s live Shopify App Store listing as of August 2026, not from an old screenshot or a competitor’s marketing page. SEOWILL (the app was formerly called SEOAnt, and its listing still credits developer CWILL) is a real, actively updated app with a genuinely large review base, an AI blog-writing engine, and automated technical fixes. If you’re trying to decide between an app that acts on your store automatically and one that explains before it acts, here’s exactly what each gets you, at every price point.

The short answer

SEOWILL vs Plug In SEO: side by side

Pricing, ratings, and features as listed on the Shopify App Store, August 2026. Check each listing for the latest — both apps update pricing periodically.

What SEOWILL is best at

The bottom line: SEOWILL is built to act on your store with minimal input — including writing blog content for you — and its free plan is a genuinely functional starting point, not a stripped trial.

The free plan alone covers an SEO checker and site audit, basic page speed optimization, alt-text editing, 50 image compressions a month, keyword research tools, an HTML sitemap, a broken-link scanner, and 30 AI blog-post credits. Paying unlocks depth and automation: Pro ($29.99/month) adds advanced speed optimization, 2,000 image compressions a month, 200 AI blog-post credits, bulk meta tag editing, JSON-LD markup, and automatic redirects for broken links; Premium ($59.99/month) adds 6,000 image compressions, 500 AI blog-post credits, a rank tracker, competitive analysis, and AMP support.

The AI blog-post engine is the clearest differentiator here — Plug In SEO doesn’t write blog content, and if that’s specifically what you need, SEOWILL fits. (If your gap is AI-generated product titles and descriptions instead of blog posts, that’s what our other app, Plug In AI, is built for — written in your store’s own voice rather than generic AI phrasing.) SEOWILL is the better fit if your real bottleneck is “I don’t have time to write blog posts, and I want technical fixes applied without reviewing each one.” Just plan to edit AI-drafted copy before it goes live rather than treating it as a finished post.

What Plug In SEO is best at

The bottom line: Plug In SEO is built to diagnose issues and explain them in plain English before anything changes on your store, with AI keyword research and rank tracking on every plan — depth SEOWILL’s listing doesn’t offer at any price, and why Plug In SEO doesn’t come free.

Its core loop is scan → explain → approve. The SEO Scanner flags technical issues (heading structure, missing schema, URL problems, double meta tags) and content issues (keywords missing from titles, descriptions, alt text, file names). Every flagged issue links to a step-by-step fix guide, so you decide what changes instead of an automated system changing it for you. Keyword Studio runs AI-powered keyword research per page and site-wide on every plan, the bulk meta editor uses additive templates (your own words wrapped around a variable like %% product.title %%, so pages stay unique instead of turning identical), and it adds Product, Article, Website, Organization, Social, BreadcrumbList, and Search structured data automatically, on every plan — not gated to a paid tier the way SEOWILL gates its bulk JSON-LD to Pro and up. Broken links get detected too, but the redirect itself is a one-click, human-confirmed step: paste the new URL, the app creates the redirect.

It’s the better fit if your real problem is “I don’t know which keywords to target or whether my SEO is actually improving, and I’d rather approve a change than trust a bot to make it” — not just get fixes applied faster or get blog drafts written for you.

The honest trade-offs

The bottom line: the real question isn’t which app has the stronger reviews — SEOWILL’s 4.9★ across 1,717 reviews (91% five-star) is a genuinely strong track record — it’s whether you want fixes and content generated automatically or explained to you first.

On the free plan itself

SEOWILL’s free tier isn’t a gimmick. A real site audit, alt-text editing, 50 monthly image compressions, keyword research tools, and 30 AI blog credits are usable features for a small store on day one. But the automation SEOWILL is best known for — bulk meta tags, JSON-LD, auto-redirects, rank tracking — sits behind the paid Pro and Premium tiers. So the free plan mostly gets you visibility and a taste of AI content, not the full automated loop. Across SaaS broadly, traditional freemium-to-paid conversion averages only around 3.7%. That’s exactly why free tiers are usually built with a ceiling, not as an afterthought.

On price once you do pay

The two ladders scale differently. SEOWILL’s tiers gate features — bulk fixes, JSON-LD, auto-redirects, and rank tracking only unlock as you move up. Plug In SEO’s three plans (Lite $29.99 / Standard $49.99 / Premium $79.99) all share the same feature set. What scales is how many products and pages you’re covering, plus AI-research and audit quotas — not what the app can do. SEOWILL’s entry Pro plan matches Plug In SEO’s entry Lite plan dollar for dollar ($29.99), but SEOWILL’s top Premium tier ($59.99) lands well below Plug In SEO’s top Premium tier ($79.99). Where SEOWILL clearly wins on access is the bottom of the ladder: it has a real $0 plan, and Plug In SEO has none, only a 14-day trial.

On what the price buys

The trade-off is automation-plus-content versus control. SEOWILL, at every tier, is about scanning, writing, and then acting — less manual work, including on content creation, but also less visibility into exactly what changed, or what an AI wrote, before it’s live. Plug In SEO adds a layer SEOWILL’s listing doesn’t offer at any price. It tells you which keywords to target, tracks whether your rankings are actually moving on every plan, and requires your approval before a meta tag or product description changes. If hands-on control and strategy guidance is what you need, that’s the reason to pay $29.99/month instead of using a free automated app — not because SEOWILL is a lesser tool, but because it’s optimized for a different kind of merchant.

How to choose between SEOWILL and Plug In SEO

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

• “I need blog content written for me and technical fixes applied without much input.” → SEOWILL’s AI blog credits and free-to-paid ladder are built exactly for this.
• “I want a real free plan before I commit to anything.” → SEOWILL has one; Plug In SEO only offers a 14-day trial.
• “I don’t know which keywords to target or whether my SEO is actually improving.” → Plug In SEO — keyword research and rank tracking are core on every plan, not add-ons gated to the top tier.
• “I want to see and approve every change before it goes live on my store.” → Plug In SEO’s scan-explain-approve loop is built for that; SEOWILL’s automated fixes and AI drafts are built for the opposite.

The honest summary: if your need is hands-off technical fixes, AI-written blog drafts, and a genuine free tier, SEOWILL is a strong, legitimate option with the review count to back it up. If your gap is strategy and control — knowing what to target, tracking whether it’s working, and approving every change — Plug In SEO is built for that, and that’s what the $29.99/month starting price is paying for.
