Best SEO Apps for Shopify in 2026: Free Plans and Prices
Seven Shopify SEO apps compared on what the free plan covers, the first paid price and what the top tier adds.
Short answer: Smart SEO is the best starting point, with a free plan that covers broken links on 100 pages and 20 AI generations, and a Pro tier at $149.90 a year. If the monthly bill is all that matters, SEO Manager starts at $9 a month, but AI content generation only comes with its $59 Professional plan. StoreSEO is the free plan to test first on a small catalog, since it stops at 25 products.

Most Shopify SEO apps sell the same job: fixing page titles, meta descriptions, image alt text, structured data and broken links across a catalog too large to edit by hand. The price difference sits in two places, the limit on the free plan and the tier that lifts it.
This page compares seven apps on those two points, plus the trial length.

Toolradar data: Toolradar tracks 259 SEO tools as of October 12, 2026, and 48% of them are free, freemium or open source, according to Toolradar's SEO tools ranking.
Five of the seven Shopify apps below have a free plan. The other two, Plug In SEO and SEO Manager, start at a paid price and rely on a 7-day trial to test.
Methodology: we read each app's Shopify App Store listing on October 12, 2026, and recorded the free plan, every paid tier, the annual price where the listing shows one and the trial length.
We ranked the seven on what the free plan covers first, then on the cheapest paid step that adds the core SEO work.

What it is
A Shopify SEO app edits or audits the search fields of your store for many products at once: page titles, meta descriptions, image alt text, structured data, sitemaps and broken links. Shopify's product editor already has a search listing for each product, so an app earns its fee when it saves hours across a large catalog, not when it adds one more field.
General SEO platforms such as Semrush and Surfer SEO are built for keyword and content research, so they are not ranked here.
Your Shopify plan is a separate bill, covered in our Shopify pricing guide and the Shopify review.
Why it matters
A free plan is a test budget, and its limit says where the test ends. StoreSEO's free plan covers 25 products, so a store with a larger catalog pays from the first week.
Smart SEO's free plan covers broken links on 100 pages and 50 image optimizations, which suits a store whose main problem is dead links or missing alt text, rather than a catalog where every title needs rewriting. For the wider app stack, see our best Shopify apps guide.
The paid step is where prices diverge.
Plug In SEO sells audit depth by pages scanned, from 200 pages on Lite to unlimited pages on Premium, and it has no free plan. SEO Manager sells monitoring at the lowest monthly price on this list, but its AI content generation only starts with the Professional tier.
Choose the app whose free limit you will hit last, then check which tier lifts that limit. Our AI apps for Shopify guide covers the wider AI tools that sit next to SEO.
Key features to look for
Pricing
The cheapest paid tier of each app, billed monthly for 12 months, works out to $108 on SEO Manager's Starter, $179.88 on Smart SEO's Pro and StoreSEO's Lite, $359.88 on Plug In SEO's Lite, $419.40 on Avada's Pro and $468 on SearchPie's Premium and Booster's Pro.
Each total is 12 monthly payments at list price, so Avada's Pro is $34.95 x 12, or $419.40.
Annual billing lowers four of those bills: Smart SEO's Pro to $149.90, Avada's Pro to $348, Booster's Pro to $349 and SearchPie's Premium to $374.40.
StoreSEO, Plug In SEO and SEO Manager show no annual price on their listings, so the monthly figure is the one you can check there.

The bottom line
Start with Smart SEO if you want a free plan to test on and the lowest published annual price for its Pro tier. Choose SEO Manager only when the monthly bill is the constraint and AI writing can wait.
For a catalog of 25 products or fewer, StoreSEO's free plan covers the test. Plug In SEO earns its entry price only if you need page-by-page audits and keyword research at scale. Read each free plan's limit first, then the paid step that lifts it.
If the store platform is still open, compare Shopify with WooCommerce in our comparison. For the email side of the same stack, see email marketing for Shopify.
