Technical SEO Checklist for eCommerce (2025 Edition)

Let’s dive into the most important technical SEO elements every eCommerce website must optimize in 2025.

1. Ensure HTTPS and Secure Site Architecture

Use an SSL certificate for HTTPS.
Redirect all HTTP URLs to HTTPS.
Update internal links to point to secure versions.

Why? Google uses HTTPS as a ranking signal, and secure sites build trust with users.

2. Fix Crawl Errors in Google Search Console

Regularly check the Coverage Report for:
- 404 errors (Page Not Found)
- Server errors (5xx)
- Redirect errors
Use 301 redirects for deleted products or categories.
Avoid using soft 404s.

Why? Crawl errors prevent search engines from accessing important pages.

3. Submit and Optimize Your XML Sitemap

Include only indexable, important URLs (no filters, duplicates, or internal search pages).
Split large sitemaps by product categories.
Submit your sitemap in Google Search Console and Bing Webmaster Tools.

Tools: Screaming Frog, Yoast SEO, Rank Math, XML-sitemaps.com

4. Optimize Robots.txt for Crawl Efficiency

Example robots.txt file:

Why? Prevents unnecessary crawling of low-value pages.

5. Set Correct Canonical Tags

Use <link rel="canonical" href="URL" /> to:

Avoid duplicate content from similar product pages
Control how search engines treat product variations (color, size, etc.)

Why? Helps consolidate ranking signals and avoids keyword cannibalization.

6. Use Structured Data (Schema Markup)

Implement structured data for:

Product (price, availability, SKU)
Review and Rating
Breadcrumb
Offer
Organization

Tools: Google’s Rich Results Test, Schema Markup Generator

Why? Enhances visibility with rich results in SERPs.

7. Improve Site Speed and Core Web Vitals

Core Web Vitals in 2025:

LCP (Largest Contentful Paint) – < 2.5s
FID (First Input Delay) – < 100ms
CLS (Cumulative Layout Shift) – < 0.1

Speed Optimization Tips:

Use fast hosting (e.g., VPS, cloud platforms)
Enable Gzip compression
Implement lazy loading
Minify CSS, JS, HTML
Serve images in next-gen formats (WebP/AVIF)
Use a CDN (Cloudflare, BunnyCDN)

Tools: PageSpeed Insights, GTmetrix, WebPageTest

8. Mobile-First Optimization

Use responsive design (avoid m-dot domains).
Make buttons tappable and navigation mobile-friendly.
Optimize mobile load speeds.

Why? Google indexes mobile versions by default. User experience on mobile directly affects rankings.

9. Clean and SEO-Friendly URL Structure

Best practices:

Use lowercase, hyphenated URLs: /category/product-name
Avoid query strings: ?id=123
Keep URLs short and descriptive

Why? Clean URLs are easier for both users and bots to understand and share.

10. Faceted Navigation and Filtered URLs

To avoid crawl issues from filters (e.g., size, color), use:

rel="nofollow" or JavaScript links for filters
Canonical URLs for all filtered results
URL parameters tool in Search Console

Why? Prevents duplicate and thin content while preserving crawl budget.

11. Pagination Best Practices

For paginated content:

Use <link rel="next"> and <link rel="prev">
Canonical each page to itself
Avoid infinite scroll without proper crawlable fallbacks

Why? Helps search engines understand the structure and flow of product category pages.

12. Optimize Internal Linking Structure

Link from:

Blog posts to product pages
Product pages to related products
Categories to subcategories

Tools: Ahrefs, Screaming Frog (to audit internal links)

Why? Strengthens crawl paths and distributes page authority effectively.

13. Avoid Duplicate Content

Don’t use manufacturer descriptions verbatim
Use canonical tags
Block low-value pages in robots.txt
Use unique metadata for every product

Why? Duplicate content harms rankings and can confuse search engines.

14. Implement Lazy Loading for Media

Only load images or videos as the user scrolls down the page.

Benefits:

Faster initial load
Better LCP scores
Reduced bandwidth

How? Use native loading="lazy" or JavaScript libraries.

15. Create a 404 Error Page That Helps Users

Include search functionality
Show popular products or categories
Add links to homepage or contact

Why? Reduces bounce rate and improves user experience.

16. Minimize Redirect Chains and Loops

Each redirect adds delay and dilutes SEO value.

Tools: Screaming Frog, Ahrefs Site Audit

Fix:

Use direct 301 redirects
Avoid multiple hops

17. Optimize for Site Architecture and Crawl Depth

Ideal structure:

Home → Category → Subcategory → Product

Tips:

Ensure important pages are 3 clicks or fewer from the homepage
Flatten deep hierarchy if possible

Why? Improves crawl efficiency and user navigation.

18. Enable Breadcrumb Navigation

Use HTML and schema markup to show breadcrumb links.

Example:
Home > Electronics > Mobile Phones > iPhone 15

Why? Improves UX and helps search engines understand site hierarchy.

19. Use a CDN for Global Reach

A Content Delivery Network (CDN) helps:

Serve content faster
Reduce latency
Improve uptime and reliability

Recommended CDNs: Cloudflare, Akamai, BunnyCDN
