Best SEO Apps for Shopify in 2026: 6 Compared
Six Shopify SEO apps compared by rating, reviews and price, from their App Store listings, plus what Shopify already does for SEO by itself.
Shopify handles more SEO by itself than most store owners realise, and most “SEO apps” sell help with the part it leaves to you. Before paying a monthly fee, it is worth knowing which is which.
We should be clear about what this article is. PureGPL sells WordPress products, and we have not run these Shopify apps on a store. What follows is what Shopify does by itself, and the ratings, review counts and prices each app shows on its own Shopify App Store listing, read on 2 October 2026.
What Shopify already does
- Lets you edit the page title, meta description and URL of every product, collection and page.
- Generates a
sitemap.xmlautomatically. - Adds canonical tags, so duplicate product addresses point to one.
- Provides a
robots.txt. - Most themes include basic product structured data.
What it does not do for you: write those titles and descriptions across hundreds of products, compress images, add alt text in bulk, extend structured data, or tell you which pages have problems. That is what the apps are for.

How to choose
- Hundreds of products with empty descriptions and alt text: a bulk editor such as SEO King or Smart SEO.
- You want rich results (stars, price, stock) in Google: a schema app such as Schema Plus.
- You want a checklist of what is wrong: an audit app such as Avada or Plug in SEO.
- You write a lot of content and know Yoast from WordPress: Yoast SEO for Shopify.
Install one at a time. Two apps that both write meta tags or structured data will conflict, and apps often leave code in your theme after you uninstall them.
What an app cannot do
No app writes product descriptions customers want to read, earns links from other sites, or makes a slow theme fast. Review counts measure how many merchants bothered to leave a review, not how much traffic the app brought them. Treat a rating of 5.0 from a few hundred reviews with the same care as any other.
Shopify or WooCommerce for SEO?
On Shopify, SEO tools are monthly subscriptions on top of your plan. On WordPress with WooCommerce, SEO plugins are paid yearly or are free, and you control the whole site. If you are on WooCommerce or considering it, see best SEO plugin for WooCommerce, where we tested five plugins on a store.
