Booster SEO vs Plug In SEO for Shopify: Which Is Cheaper?

2026-10-10 · seo

If you're running a Shopify store and comparing SEO apps, Booster SEO and Plug In SEO are two names that come up constantly—usually because both offer a free tier and both promise better rankings without you touching code. The real question isn't which one has more features. It's which one costs you less for the traffic and product count you actually have.

Booster SEO vs Plug In SEO: What Each App Actually Does

Booster SEO (by Booster Apps) is built around bulk optimization. It scans your store, flags missing meta titles, descriptions, and image alt text, and lets you fix them in batches rather than one product at a time. It also handles JSON-LD structured data, sitemap generation, and Google Search Console integration. The pitch is speed: get a store with hundreds of products into decent SEO shape in an afternoon.

Plug In SEO (by Illumination Digital) takes a diagnostic-first approach. It runs a health check across your store and produces a prioritized list of issues—broken links, duplicate content, missing metadata, slow-loading pages—with plain-English explanations of why each one matters. It also includes a built-in SEO score, competitor comparison tools on higher plans, and tracking for keyword rankings.

The practical difference:

• Booster SEO is a fixer. You point it at problems and it helps you resolve them fast.
• Plug In SEO is a checker. It tells you what's wrong and educates you on the fix, which suits store owners who want to learn SEO rather than outsource it.

Neither app replaces good product copy or a solid site structure. Both are tools for catching the mechanical errors that quietly suppress rankings.

Pricing Breakdown: Monthly Costs and Free Plan Limits

Both apps use freemium pricing, which makes direct comparison tricky because the free tiers cap you in different ways.

The important detail is what the free plan limits. Booster SEO's free tier historically restricts how many products you can optimize or how many bulk actions you can run. Plug In SEO's free tier typically limits how many issues it will surface or which diagnostic tools you can access.

Because both vendors adjust pricing and plan boundaries periodically, check current pricing in the Shopify App Store before you commit. What matters for your budget is whether the free tier covers your catalog size—a 30-product store and a 3,000-product store will hit the paywall at very different points.

One cost people forget: if you outgrow the free plan on either app, you're paying monthly forever. At roughly $20–$40/month (verify current rates), that's $240–$480 a year—real money for a small store. Compare that against the one-time cost of hiring someone to fix your SEO manually, which for a small catalog may actually be cheaper.

Feature Comparison: What You Get at Each Price Point

On free plans, expect:

• Basic metadata editing (titles and descriptions)
• Some form of site scan or health check
• Limited bulk actions or capped issue reporting
• No competitor tracking or advanced schema tools

On paid plans, expect:

• Unlimited or near-unlimited bulk optimization
• Structured data / rich snippet support
• Keyword tracking and rank monitoring
• Broken link detection and redirect management
• Priority support

Booster SEO leans harder into automation and bulk editing on paid tiers. Plug In SEO leans into reporting, education, and competitive analysis. If you want the app to do the work, Booster SEO's paid tier is more directly useful. If you want to understand your SEO gaps, Plug In SEO's diagnostics are more valuable.

Neither app writes content for you, builds backlinks, or fixes page speed. Budget separately for those if they're gaps in your store.

Which App Is Cheaper for Your Traffic Level?

Traffic level matters less than product count and how often you add new items.

• Under 50 products, low traffic: Both free tiers likely cover you. Cost: $0. Pick based on which interface you prefer.
• 50–500 products: You'll probably hit free-tier caps on bulk actions. One paid plan on either app is enough—don't pay for both.
• 500+ products, regular new listings: Paid tier is unavoidable. Booster SEO's bulk automation tends to save more time here, which has a real labor cost even if the subscription price is similar.
• High traffic, competitive niche: You need rank tracking and competitor data, which pushes you toward Plug In SEO's higher tiers—or a dedicated tool like Ahrefs or Semrush alongside a cheaper Shopify app.

The cheapest option is rarely the free plan if it leaves 200 products with duplicate meta descriptions. Fixing that manually costs more in your time than a $20/month subscription.

Best for Small Stores on a Tight Budget

If you're under 50 products and just launched:

• Start with Plug In SEO's free tier to get a clear picture of what's broken.
• Fix the top 10 issues manually using its guidance.
• Only upgrade if you're adding products weekly and the manual fixes become a bottleneck.

This approach costs nothing and teaches you the fundamentals. Booster SEO's free tier works too, but its value is in bulk actions—which you don't need at this size.

Best for Stores Planning to Scale

If you're heading toward 500+ SKUs or running paid ads that depend on organic landing pages:

• Booster SEO's paid tier pays for itself in time saved on bulk metadata and schema.
• Add Plug In SEO only if you specifically need its competitor or rank-tracking features—otherwise you're paying twice for overlapping diagnostics.

Scaling stores should also budget for a proper keyword research tool. Neither app substitutes for that.

Final Verdict: Choosing Based on Your Monthly Budget

If your budget is $0, run Plug In SEO's free tier first, fix what it flags, and revisit in 90 days. If your budget is $20–$40/month and you have more than 100 products, Booster SEO's paid tier delivers more automation per dollar. If you need rank tracking and competitor insight, Plug In SEO's higher tiers justify the cost—but only if you'll actually use the data. Don't pay for both; they overlap heavily on the basics.

Conclusion: For most small Shopify stores, the cheaper path is starting free with Plug In SEO, then switching to Booster SEO's paid plan once bulk editing becomes a time sink. Match the app to your product count, not to feature lists you'll never use.

FAQ

Is Booster SEO free forever? Both apps offer free plans, but "free" comes with usage caps on products or actions. Check current pricing to confirm what the free tier includes today—vendors change limits.

Can I use Booster SEO and Plug In SEO at the same time? You can, but it's usually wasted money. They overlap on metadata editing, site scanning, and schema. Pick one for core SEO and spend the savings on content or a keyword tool.

Do I need a paid SEO app at all for a small Shopify store? Not necessarily. Under 50 products, manual fixes guided by a free diagnostic tool often outperform a subscription—especially if you're not adding products regularly.
