SEOLab VS SEOWill Which Shopify SEO App Is Better in 2026?

SEOLab is the better choice for most Shopify stores in 2026 because it includes for free what SEOWILL sells on Pro ($29.99) and Premium ($59.99) plans. SEOLab gives you bulk meta tags, JSON-LD, alt text, image compression, and auto fix for broken links with no image quotas, credit meters, or on-page audit caps listed. SEOWILL is a well reviewed, Built for Shopify app, rated 4.8 from 1,813 reviews and live since 2019, with an AI blog generator and support that reviewers praise, 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 SEOWILL's own help center on 3 October 2026, cited dated merchant reviews with the developer's replies, and gave SEOWILL a section of its own. SEOWILL's listing and help center are the source for every SEOWILL price and limit below, and third-party roundups were not used. SEOWILL also sells a separate speed app, and this post covers SEOWILL: AI SEO and AI Blog Post.

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

Ratings come from the live SEOLab listing and SEOWILL 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.

What Does Each Plan Really Include?

SEOWILL sells a free plan and two paid plans, and the real differences are monthly image allowances, AI credit pools, and how many pages the on-page audit covers. Here they are side by side with SEOLab.

SEOWILL's listing adds that recurring and usage-based charges are billed every 30 days. Check the app for the plan you would actually be offered.

What Does a Year of SEOWILL Really Cost?

On monthly billing, 12 months of Pro is about $360 and 12 months of Premium is about $720. The annual plans are listed at 20 percent off, $287.90 for Pro and $575.90 for Premium, which saves about $72 and $144. SEOLab is free at the time of writing, and the figures below exclude any usage-based charges.

Annual billing is a fair discount if you are sure you will keep the app, and the 7 day trial lets you test it first. The point is that with SEOLab there is no plan to commit to, while with SEOWILL the price follows your needs for images, credits, and audits.

How Do the Image Compression Allowances Compare?

Image compression is SEOWILL's strongest practical feature. A September 2026 reviewer compressed 11,870 images and reported about 96 percent savings, roughly 7 GB, and said the compressed files stay on Shopify's CDN after cancelling. SEOWILL's listing allows 50 images on Free, 2,000 a month on Pro, and 6,000 a month on Premium. SEOLab's Image Optimization tab reports images optimized and average size saved, with no monthly image quota listed, and its Alt Tags tab has a Fix all alt text button.

• Small catalogs: 2,000 images a month covers many stores, and the quota resets monthly.
• Big one-off jobs: a 12,000 image store needs two months on Premium, while SEOLab has no cap listed.
• Safety: a December 2025 reviewer said the app replaced product images with cached versions, so keep your own copy of originals before any bulk run, on any app.

See our image optimization guide and the Image Compression page.

What Should You Know About Credits and Auto-Charge?

SEOWILL's AI features run on credits, and credits can be topped up by an auto-charge setting. In September 2026 a US reviewer on the free plan said they were charged for AI. SEOWILL's reply said the free plan has limited AI quotas and the charge came from used up credits with an overcharge toggle enabled, and it offered a full refund. In August 2026 another US store said it paid $200 in one day and got a full refund through support.

SEOWILL's help center says to adjust the limit under Settings, Account, Auto-charge, and that because of Shopify's limitations you can only increase the spending limit, not lower it afterward. That is a design worth knowing before you click anything AI related. SEOLab's AI Optimizer has no credit meter, so there is no spending limit to manage.

To stay safe on any credit-based app, open the billing settings before your first bulk job, check what is charged beyond the plan, and watch the Shopify billing page for the next 30 day cycle.

How Do the On-Page Audit Limits Compare?

SEOWILL's on-page audit covers 20 pages on Free, 1,000 pages on Pro, and unlimited pages on Premium. Every product, collection, page, and blog post is a page, so a store with 1,500 products passes the Pro limit alone. SEOLab's Page Optimization scores every product, collection, blog, and page in one scan with no cap listed, and SEO Audit and Site Health returns a health score, mobile and desktop speed scores, and a prioritized Do These Next list. See the SEO Audit and Site Health page.

Audit accuracy matters as much as audit size. A September 2026 reviewer said SEOWILL reported 3,051 pages with multiple H1 tags when independent checks found one per page, and flagged 2,720 pages as title too short when they were too long. SEOWILL replied that all three points were valid, that full scans run at installation and then need manual rescans, and that titles are measured from Shopify's SEO field only and not from the store name a theme appends. It committed to measuring rendered titles in pixel width. Whichever audit you use, spot check a few flagged pages in your browser before you bulk fix.

Is an AI Blog Generator Worth It, or Is Page Optimization Enough?

This is where SEOWILL genuinely differs. Its listing includes a blog builder with a drag-and-drop editor, templates, bulk creation, multi-language output, embedded products, and AI generation, and the free plan includes 30 blog credits. SEOLab does not list a blog generator, and focuses on the meta tags, schema, alt text, and links of the pages you already have.

Before you generate content in bulk, remember what Google says. Its spam policies target scaled content abuse, meaning many pages produced mainly to manipulate rankings without helping users, however they are made. Use AI to draft, then add real expertise, product detail, and photos. Our meta titles guide and the Meta Title and Description Optimizer page cover the on-page side.

How Do Speed Optimization and Theme Code Compare?

SEOWILL's one-click speed optimization duplicates your current theme, applies changes such as image compression and CSS and JavaScript optimization to the copy, lets you preview it, and keeps your original theme restorable. That is a careful design, and the tiers are Basic on Free, Rocket on Pro, and Turbo on Premium.

Reviews show why you should still preview. A 2025 reviewer said speed optimization disabled checkout functionality, and 2026 reviewers in the UK and Ukraine said code or HTML sitemap links stayed in their theme after uninstalling. SEOWILL's reply attributed residue to revoked API access tokens and promised better offboarding documentation. SEOLab includes a Speed Booster and separate mobile and desktop scores. Whichever you use, test checkout, cart, and key pages, and read our speed optimization guide.

How Do They Compare on Technical SEO, JSON-LD, and Broken Links?

SEOWILL lists JSON-LD, FAQ, and How-To schema, auto redirect for broken links, bulk meta tag editing, and sitemap tools from Pro, and its help center has articles on structured data, 301 redirects, and managing 100,000 plus redirects. SEOLab includes JSON-LD and an auto fix toggle for broken links in its free install, alongside a robots.txt customizer and a Sitemap and Indexing Manager that connects to Google Search Console.

After enabling schema in any app, test a product URL in the Rich Results Test, and read our JSON-LD guide. For redirects, our broken links playbook explains why sending every 404 to one target is triage, not strategy, and the Broken Link Redirects and Sitemap and Indexing Manager pages show the workflows.

What About AI Visibility and llms.txt?

SEOWILL lists llms.txt from Pro and competitor GEO and SEO analysis on Premium, and SEOLab includes LLMs.txt and Agents.md on the built-in plan. Keep this 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 Do Merchants Say About Each App?

SEOWILL holds a 4.8 rating, with 91 percent of its 1,813 reviews at five stars and 51 at one star. Its newest reviews, from July to September 2026, repeatedly praise support, with merchants calling the team responsive, quick, and helpful. The critical reviews tell a fuller story, so here are the patterns on SEOWILL's 1-star reviews:

These are individual reports against 1,813 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 and credits before you click, duplicate your theme first, test bulk image jobs on a few products, and verify a live page after changes.

How Do You Switch From SEOWILL to SEOLab Safely?

Final Verdict: Which App Should You Choose?

Across meta tags, JSON-LD, broken links, indexing, images, audits, speed, and AI search, SEOLab covers the same ground as SEOWILL's Pro and Premium tiers at no cost, and without image quotas, credit pools, or an auto-charge setting to watch. That matters most on large catalogs, where 2,000 products push SEOWILL past its Pro audit limit and a 12,000 image library takes months of allowance. 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.

SEOWILL remains a credible option if you want an AI blog generator with bulk creation, a speed optimizer that works on a copy of your theme, and a team that reviewers praise, and you are comfortable managing credits and paying $29.99 to $59.99 a month. Whichever you choose, do not stack two SEO apps, and verify results in Google Search Console after any change.
