E-commerce SEO Strategies

Introduction to E-commerce SEO

E-commerce SEO presents unique challenges including large product catalogs, faceted navigation, duplicate content, and conversion optimization. This lesson covers advanced strategies for online stores.

1. Product Page Optimization

Each product page should be a comprehensive resource that satisfies user intent.

Optimal Product Page Structure

<!-- Product Page SEO Structure -->
<article itemscope itemtype="https://schema.org/Product">
    <!-- Breadcrumb Navigation -->
    <nav aria-label="Breadcrumb">
        <ol itemscope itemtype="https://schema.org/BreadcrumbList">
            <li itemprop="itemListElement" itemscope 
                itemtype="https://schema.org/ListItem">
                <a itemprop="item" href="/">
                    <span itemprop="name">Home</span>
                </a>
                <meta itemprop="position" content="1" />
            </li>
            <!-- Additional breadcrumb items -->
        </ol>
    </nav>
    
    <!-- Product Title (H1) -->
    <h1 itemprop="name">Product Name - Key Feature - Brand</h1>
    
    <!-- Product Images with Alt Text -->
    <img itemprop="image" 
         src="/images/product-main.jpg"
         alt="Product Name - Front View - Brand"
         loading="eager" />
    
    <!-- Price and Availability -->
    <div itemprop="offers" itemscope 
         itemtype="https://schema.org/Offer">
        <span itemprop="price" content="99.99">$99.99</span>
        <link itemprop="availability" 
              href="https://schema.org/InStock" />
    </div>
    
    <!-- Product Description (Unique, 300+ words) -->
    <div itemprop="description">
        <!-- Detailed, unique description -->
    </div>
</article>

Product Description Template

# Product Description Structure (300-500 words)

## Opening Hook (50 words)
Address the primary problem the product solves

## Key Benefits (100 words)
- Benefit 1 with specific detail
- Benefit 2 with measurable outcome
- Benefit 3 with use case

## Features & Specifications (150 words)
Technical details that support purchasing decision

## Use Cases (100 words)
Who this product is for and how they will use it

## Social Proof
Customer testimonials, awards, certifications

2. Category Page SEO

Category pages often have the highest commercial intent and ranking potential.

Category Page Optimization

<!-- Category Page Structure -->
<main>
    <!-- SEO Content Block (Above Products) -->
    <header class="category-header">
        <h1>Wireless Headphones - Premium Audio Quality</h1>
        <p class="category-intro">
            150-200 word introduction with primary keywords
        </p>
    </header>
    
    <!-- Faceted Navigation -->
    <aside class="filters">
        <!-- Price, Brand, Features filters -->
    </aside>
    
    <!-- Product Grid -->
    <section class="products">
        <!-- Product cards with schema -->
    </section>
    
    <!-- Pagination -->
    <nav class="pagination">
        <a rel="prev" href="?page=1">Previous</a>
        <a rel="next" href="?page=3">Next</a>
    </nav>
    
    <!-- SEO Content Block (Below Products) -->
    <section class="category-content">
        <h2>Buying Guide: How to Choose Wireless Headphones</h2>
        <!-- 500+ word guide with internal links -->
    </section>
</main>

3. Faceted Navigation SEO

Faceted navigation can create millions of URL combinations. Proper handling is critical.

Faceted Navigation Strategy

# URL Parameter Handling Strategy

## Index These (High Search Volume)
/headphones/wireless/
/headphones/brand-sony/
/headphones/over-ear/

## Canonicalize These (Low Volume Combinations)
/headphones/?color=black → canonical to /headphones/
/headphones/?sort=price-low → canonical to /headphones/

## Block These (No Search Value)
/headphones/?color=black&brand=sony&price=100-200&sort=newest
robots.txt: Disallow: /*?*&*&*

# Implementation
<link rel="canonical" href="https://store.com/headphones/" />
<meta name="robots" content="noindex, follow" />

PHP Canonical Logic

<?php
function get_canonical_url($category, $filters) {
    // High-value single filters to index
    $indexable_filters = ['brand', 'type', 'material'];
    
    $canonical = "/" . $category . "/";
    $indexed_params = [];
    
    foreach ($filters as $key => $value) {
        if (in_array($key, $indexable_filters) && count($filters) === 1) {
            // Single high-value filter = indexable
            $canonical .= $key . "-" . slugify($value) . "/";
            return $canonical;
        }
    }
    
    // Multiple filters = canonical to category
    return "/" . $category . "/";
}

function should_noindex($filters) {
    // Noindex if more than 2 filters or low-value filters
    $low_value = ['sort', 'page', 'view', 'color'];
    
    if (count($filters) > 2) return true;
    
    foreach ($filters as $key => $value) {
        if (in_array($key, $low_value)) return true;
    }
    
    return false;
}
?>

4. Product Schema Markup

Rich snippets significantly improve click-through rates for product pages.

Complete Product Schema

        }
    ]
}

5. Handling Out-of-Stock Products

Proper handling prevents losing rankings while maintaining user experience.

Out-of-Stock Strategy

# Decision Tree for Out-of-Stock Products

## Temporarily Out of Stock (returning soon)
- Keep page live
- Update schema: availability = OutOfStock
- Show expected restock date
- Add "Notify Me" functionality
- DO NOT noindex

## Permanently Discontinued
Option A: High-ranking page with traffic
- Keep live, show alternatives
- Add "This product is discontinued"
- Internal link to replacement products

Option B: Low-traffic page
- 301 redirect to:
  1. Replacement product
  2. Parent category
  3. Similar product

## Seasonal Products
- Keep pages live year-round
- Update content for seasonality
- Build links during off-season
