Field guide

**Most stores need two or three SEO apps, not ten. TinyIMG covers image compression, JSON-LD, and broken links from $14 a month. SEO Manager handles bulk titles, descriptions, and redirects from $9 a month. Plug In SEO runs plain-language audits from $29.99 a month. Pick one tool per job, image weight, metadata at scale, or technical audits, and check pricing before buying, because it changes often.**

## One tool per job, not ten tools

Every SEO roundup lists sixteen apps and implies you need them all. You do not. A Shopify store has three SEO jobs an app can actually do: compress images at scale, add schema the theme misses, and find broken links and missing metadata across a large catalog. One tool per job is the whole stack, and adding a fourth app usually adds a second subscription for a job already covered.

That is the frame for this list. Each app below is judged on the one job it does best, with its price and its limit stated, so a store owner can build the stack in an afternoon instead of trialing tools for a month.

## TinyIMG: images, schema, and broken links in one place

TinyIMG is the best overall pick in most 2026 roundups because it covers the three jobs at once. It compresses images without visible quality loss, up to 70 percent file size reduction, adds alt text automatically, implements JSON-LD structured data, and includes lazy loading and IndexNow for faster indexing of new content.

It is free to install with 50 image optimizations a month, then $0.03 per additional image, and paid plans run $14, $23, and $49 a month. The Advanced plan adds LLMs.txt generation, which matters for stores chasing AI search visibility. Image-heavy stores should start here.

## SEO Manager and Plug In SEO: the other two jobs

SEO Manager is the metadata tool. It gives direct control over titles, meta descriptions, and canonical tags across the whole catalog, flags broken links before Google does, and explains what each setting does, which makes it the best pick for owners who want to learn SEO while doing it. It starts at $9 a month with no free plan.

Plug In SEO is the audit tool. It scans the store, lists every issue in order of impact, and explains each one in plain language without jargon. It starts at $29.99 a month for up to 200 scanned pages, with a 7-day trial, and it is the best first audit for a store that has never been checked.

## What to skip, and the specialist pick

Skip the all-in-one suites that duplicate what TinyIMG already covers, and skip any app that promises keyword rankings without showing its method. The one specialist worth the money is JSON-LD for SEO, which does a single job properly, advanced monitored schema markup, at $399 a year. Stores chasing rich results should add it. Everyone else should stop at three apps and spend the saved subscription money on content.

## Frequently asked questions

### What is the best SEO app for Shopify?

For most stores, TinyIMG, because it covers image compression, JSON-LD schema, and broken links in one subscription from $14 a month. Add SEO Manager for bulk metadata control and Plug In SEO for audits, and stop at three apps.

### Is there a free SEO app for Shopify?

Yes. TinyIMG is free to install with 50 image optimizations a month, and Plug In SEO and Avada SEO both offer free tiers. Avada has the most generous free tier of the group. Check the usage limits before relying on a free plan, since most cap products, pages, or images.

### Do I need an SEO app if my theme already has SEO features?

Probably still yes for images and audits. Themes rarely compress images in bulk, add missing schema, or scan for broken links across a large catalog. Those three jobs are exactly what the apps above cover, and they are the jobs themes skip.

### How many SEO apps should a Shopify store install?

Two or three at most, one per job. Image optimization, metadata at scale, and technical audits. More than three usually means paying twice for the same job, and too many apps can slow the store they are meant to optimize.
