SEO King vs Yoast SEO for Shopify (2026): which should you pick?

Pick SEO King if

• Fits if you run a Shopify store and want AI meta text without counting credits
• Works for large catalogs, since 20,000 pages is $16.99 a month

Look elsewhere if

• Skip it if your store isn't on Shopify, as that's the only place it installs
• Tight if you stay free, because AI text, bulk photo work, robots.txt and llms.txt are all paid
• Watch out: alt text read from the photo itself is about $1 per 400 photos, and translation and upscaling also use prepaid credits
• Pricey if you want it done for you, as the Full-Service tier is $95 a month or $595 a year, with no theme work

Pick Yoast SEO for Shopify if

• Fits if your team writes a lot of product and blog copy and wants tips while it types
• Works for merchants who already know Yoast from WordPress

Look elsewhere if

• Skip it if you're not on Shopify, as it installs and bills only through Shopify
• Not for you if you want a free plan, since the trial ends at $19 every 30 days plus VAT
• Pricey if you want to see how AI assistants describe you: that's AI+ at $45 a month, in a separate MyYoast account
• Watch out: star ratings in Google need a supported reviews app installed alongside it
• Too light for fixing broken links or redirects, which the listing doesn't mention

SEO King

• Works only on Shopify stores; it is installed from the Shopify App Store.
• AI text, auto-updating, bulk photo work, robots.txt, llms.txt and advanced JSON-LD all need a paid tier; tiers differ only in pages covered.
• Vision AI, translation, upscaling and background removal are paid per use from prepaid credits, or by an optional unlimited AI credits plan.
• A done-for-you Full-Service tier with expert setup and monthly strategy calls costs $95 a month or $595 a year, without theme work.

Yoast SEO for Shopify

• Works only on Shopify stores; it is installed from the Shopify App Store and billed through Shopify.
• There is no free plan: the 14-day trial leads to $19 per 30 days, and Yoast's site quotes prices before VAT.
• AI Brand Insights needs AI+ at $45 a month and is used in a MyYoast web account, not inside the Shopify app.
• Star ratings in search results need a supported reviews app installed alongside it.
