10 SEO Mistakes That Cost Ecommerce Stores Rankings (And Revenue)

2 min read

After scanning thousands of ecommerce stores, we see the same SEO mistakes over and over. Most of them are easy to fix once you know they exist. Here are the ten that cost store owners the most traffic and revenue.

1. Missing or Duplicate Meta Descriptions

Nearly 40% of product pages we scan have either no meta description or a duplicate one shared across many products. Google shows meta descriptions in search results — they're your free advertising copy. Each product page should have a unique, compelling 120-160 character description that includes the product name and a call to action.

2. No Product Schema Markup

Without Product schema, your listings in Google are plain blue links while competitors show star ratings, prices, and availability. Rich results can increase click-through rates by 20-30%. Most themes include basic schema, but often miss required fields like offers.price or offers.availability.

3. Ignoring Duplicate Content

Shopify creates collection-path duplicates automatically. WooCommerce creates filter and sort parameter URLs. Both create variant URLs. If canonical tags aren't configured correctly, Google sees dozens of duplicate pages for every product — splitting your ranking power across all of them.

4. Slow Page Speed

The average ecommerce store scores 25-40 on Google PageSpeed (mobile). The usual culprits: unoptimized product images, too many apps/plugins, no caching (WooCommerce), and heavy third-party scripts. Every extra second of load time costs roughly 7% in conversions.

5. Missing Canonical Tags

Canonical tags tell Google which version of a page is the 'official' one. Without them, Google guesses — and often guesses wrong. This is the single most impactful technical SEO fix for most ecommerce stores.

6-10: The Rest of the List

**6. Missing alt text on images** — Google Images drives 20-60% of ecommerce traffic. No alt text = invisible images. **7. Broken internal links** — Dead links waste crawl budget and create poor user experience. **8. No SSL / Mixed content** — HTTP pages get 'Not Secure' warnings that kill conversion rates. **9. Thin product descriptions** — Pages with under 50 words of content struggle to rank. **10. Not submitting a sitemap** — Your sitemap helps Google discover all your products. If it's not referenced in robots.txt, Google may miss it. Want to know which of these affect your store? Run a free RankRipper scan — we check for all 10 and give you copy-paste fixes for each one.
