SEO Basics That Merchants Miss in Shopify Themes

Most Shopify SEO issues are not advanced. They are basic problems that hide in themes and templates:

• missing or inconsistent headings
• thin templates that render empty content
• broken internal links
• duplicate content patterns caused by filters or query params

This post is not a full SEO guide. It is a practical checklist you can apply to most Shopify stores.

1) Heading structure (H1/H2)

Common theme mistakes:

• multiple H1s on the same page
• no H1 on product pages
• heading styles used without semantic headings

Quick checks:

• product pages have one clear H1 (product title)
• collection pages have one clear H1 (collection title)

2) Empty templates and “thin pages”

Some pages exist but render almost nothing:

• empty collection templates
• blog pages with no content
• product pages missing descriptions

Thin pages lower perceived site quality.

3) Internal links and broken navigation paths

Broken internal links often appear after:

• theme refactors
• menu changes
• app installs/uninstalls

Check:

• header and footer links
• collection links on the home page
• blog links and article links

4) Duplicate content patterns

Common sources of duplication:

• multiple URLs with different query params rendering the same content
• tag pages and filtered pages that create near-duplicates

You do not need to solve everything at once. Start by identifying the patterns, then decide what to index.

5) Image alt text and media hygiene

Alt text is not a magic SEO lever, but it improves accessibility and helps with image search.

Check:

• hero images have descriptive alt text
• decorative images use empty alt attributes where appropriate

6) Performance as an SEO input

Slow UX often correlates with worse SEO outcomes:

• users bounce
• pages render late
• heavy scripts delay content

If you have to choose between “more widgets” and “faster store”, speed usually wins.

A simple SEO maintenance habit

Once per month:

• scan for broken links and empty templates
• review product pages missing descriptions
• review new scripts and heavy assets

SEO improves when the storefront stays clean and predictable.
