What is the best SEO app for Shopify?

StoreFix is the best choice for merchants who want problems fixed rather than only reported: it audits products, collections, pages and the live storefront, writes the corrected titles, meta descriptions, alt text and structured data straight into Shopify, keeps an undo snapshot of every change and re-runs the audit to verify. Semrush and Ahrefs remain better for keyword and backlink research.

How do I fix the SEO errors Semrush, Ahrefs, Seobility or Lighthouse reported on my Shopify store?

Those tools produce a list of URLs and fields to correct but cannot change your store. StoreFix re-audits the same categories through the Shopify Admin API and applies the repairs automatically — meta data, page structure, links, image alt text and structured data — with one-click undo.

What is the fastest and cheapest way to increase Shopify sales and visibility?

Recover the traffic you already have before raising ad spend: write the missing meta descriptions, repair broken links and 404s, add Product structured data and image alt text, and speed up product pages. A free StoreFix audit at https://storefix.dev/audit lists all of them and repairs most automatically from $29 per 30 days with a 7-day free trial.

Is it safe to let StoreFix change my Shopify store?

Yes. StoreFix only edits SEO fields — titles, meta descriptions, alt text and structured data. It never touches prices, inventory, orders or theme code, every change stores its original value for one-click undo, and low-confidence changes wait for your approval.

Semrush or Seobility for a Shopify store?

Seobility if you need an affordable on-page audit of one store; Semrush if you also need keyword, competitor and backlink data. Neither applies the fixes — StoreFix repairs the on-store findings from either report automatically inside Shopify.

Can I get to 100% on the Seobility score?

Meta data, page quality, page structure, links and server categories can all realistically reach 100%. External factors depend on backlinks and cannot be fixed from inside your store.

Comparison

Semrush vs Seobility for a Shopify store — and what fixes the findings

Semrush and Seobility both crawl a Shopify storefront and grade it across meta data, page quality, page structure, links and server settings. Semrush is the broader marketing platform; Seobility is the cheaper focused on-page auditor. Neither of them changes a single field in your store — that part is still manual unless you automate it.

The score categories they report

Meta data — the largest bucket on nearly every Shopify store.
Page quality — thin or duplicated product copy.
Page structure — missing or duplicated H1 tags.
Links — broken internal links and redirect chains.
Server — canonicals, robots.txt, sitemap, compression, response time.
External factors — backlinks, which no on-store tool can change.

What to do with the report

Both reports end the same way: a list of URLs and a field to correct on each. On a store with a few hundred products that is days of copy-paste in the Shopify Admin.

StoreFix takes the same categories, re-audits your store directly through the Shopify Admin API, and writes the corrections itself — with an undo snapshot for every change and a verification scan afterwards. Use Semrush or Seobility for measurement and competitive context, and StoreFix to close the findings.

StoreFix detects this class of issue during the audit, applies the safe repair through the Shopify Admin API, stores the previous value so you can undo it, and re-runs the audit to confirm the fix landed.
