For a Dhaka-based ecommerce store, failing to optimise images can cost you ৳50,000 or more per quarter in lost organic traffic and conversions. Competitors who optimise get the lion’s share.

Phase 1: Technical Optimisation

Start by ensuring your images are technically sound. This means proper naming, compression, and responsive dimensions. Without these, even great content won’t rank.

Tactic 1.1: Descriptive File Names

Why this works: Google uses file names to understand image content. A descriptive name like “women-red-dress-size-m.jpg” signals relevance, while “IMG_9482.jpg” tells nothing.

Exactly how to do it:

1. Use hyphens between words, no underscores.
2. Include primary keyword and product attributes (color, size, material).
3. Keep it under 50 characters where possible.
4. Avoid stop words like ‘the’, ‘a’, ‘an’.
5. Rename all images before uploading.
6. Be consistent across all product images.

Pro template: [product-name]-[color]-[size]-[material].jpg
Example: blue-cotton-t-shirt-large.jpg

📊 Expected results: 20-30% increase in image search impressions within 2-3 months.

Tactic 1.2: Compression and Format

Why this works: Faster page load improves user experience and SEO. Compressed images load quicker, reducing bounce rates.

Exactly how to do it:

1. Choose WebP for best compression; fallback to JPEG if needed.
2. Compress images to under 100KB using tools like TinyPNG or ImageOptim.
3. Maintain quality: aim for 80-85% quality setting.
4. Use exact dimensions (e.g., 800x800px for product thumbnails).
5. Implement lazy loading to defer offscreen images.
6. Serve responsive images via srcset attribute.

Pro script: Use ‘cwebp -q 80 input.jpg -o output.webp’ for batch conversion.

📊 Expected results: 40% reduction in page load time, 15% increase in organic clicks.

Tactic 1.3: Responsive Images and Lazy Loading

Why this works: Google prioritises mobile-first indexing. Images that resize for mobile improve user experience and rankings.

Exactly how to do it:

1. Add srcset and sizes attributes to img tags for multiple resolutions.
2. Use CSS max-width: 100% to ensure images scale.
3. Implement lazy loading with loading=”lazy” attribute.
4. Test with Google’s Mobile-Friendly Test.
5. Use picture element for art direction if needed.

Pro template: <img src=”small.jpg” srcset=”medium.jpg 768w, large.jpg 1280w” sizes=”(max-width: 768px) 100vw, 50vw” alt=”…”>

📊 Expected results: 25% improvement in mobile image rankings.

Phase 2: Content Optimisation

Now focus on the textual context around images. Alt text, surrounding text, and image sitemaps help Google understand and index images.

Tactic 2.1: Alt Text and Title Attributes

Why this works: Alt text is read by screen readers and used by Google as a ranking signal. Title attributes provide additional context.

Exactly how to do it:

1. Write descriptive, natural alt text (5-10 words).
2. Include focus keyword if relevant.
3. Don’t keyword stuff; make it useful for accessibility.
4. Keep title attribute brief (optional).
5. Ensure every product image has unique alt text.

Pro template: “Women’s blue cotton t-shirt – size large – comfortable fit”

📊 Expected results: Up to 30% more traffic from image search.

Tactic 2.2: Surrounding Text and Context

Why this works: Google uses surrounding content to determine image relevance. Placing images near keyword-rich text boosts rankings.

Exactly how to do it:

1. Place images close to relevant product descriptions.
2. Use captions or adjacent paragraphs with keywords.
3. Include product name and price in the page text.
4. Use structured headings (H2, H3) near images.
5. Add a “Customer Reviews” section with image context.

Pro script: “This blue t-shirt is made of 100% organic cotton and available in sizes S-XXL.”

📊 Expected results: 15% improvement in image relevance scores.

Tactic 2.3: Image Sitemap

Why this works: An image sitemap helps Google discover and index images, especially for large ecommerce sites.

Exactly how to do it:

1. Include image URLs in your XML sitemap.
2. Use the tag with caption, title, and license.
3. Submit sitemap to Google Search Console.
4. Update sitemap whenever new product images are added.
5. Verify indexing via Search Console.

Pro template (XML): <url><loc>https://example.com/product-page</loc><image:image><image:loc>https://example.com/product.jpg</image:loc></image:image></url>

📊 Expected results: 50% more indexed images within a month.

Phase 3: Structured Data

Schema markup helps Google understand your images as product images. Implementing structured data can lead to rich results like image carousels.

Tactic 3.1: Product Schema Markup

Why this works: Product schema provides explicit details about the product including image, price, availability. Google can display this in search results.

Exactly how to do it:

1. Use JSON-LD format for product schema.
2. Include ‘image’ property with full URL of product image.
3. Add ‘name’, ‘description’, ‘offers’, ‘brand’.
4. Test with Google’s Rich Results Test.
5. Ensure each product page has unique schema.

Pro script (JSON-LD): { “@context”: “https://schema.org”, “@type”: “Product”, “name”: “Blue Cotton T-Shirt”, “image”: “https://example.com/blue-cotton-tshirt.jpg”, “description”: “Soft cotton t-shirt available in sizes S-XXL.”, “offers”: { “@type”: “Offer”, “priceCurrency”: “BDT”, “price”: “750” } }

📊 Expected results: 20% higher click-through rate from rich results.

Tactic 3.2: ImageObject Schema

Why this works: ImageObject schema provides additional properties like caption, author, license, helping Google understand image context.

Exactly how to do it:

1. Add ImageObject markup on the image itself.
2. Use ‘contentUrl’, ‘description’, ‘author’.
3. Combine with Product schema for best results.
4. Test with structured data testing tool.

📊 Expected results: Enhanced visibility in image searches.

Tactic 3.3: Breadcrumb and Review Schema

Why this works: Breadcrumbs help users and Google understand site structure, while review schema adds social proof.

Exactly how to do it:

1. Implement breadcrumb schema on product pages.
2. Add aggregate rating schema if you have reviews.
3. Use ‘review’ property in Product schema.

📊 Expected results: Higher trust and click-through rates.

Phase 4: Advanced Tactics

Go beyond basics with LSI keywords, A/B testing, and leveraging visual search technologies.

Tactic 4.1: LSI Keywords for Images

Why this works: Latent semantic indexing (LSI) keywords help Google understand the context and relevance of your images.

Exactly how to do it:

1. Use related terms like “stylish”, “casual”, “summer” for a t-shirt image.
2. Include in image file name, alt text, and surrounding text.
3. Use tools like LSIGraph to find related keywords.
4. Don’t overdo; natural integration is key.

📊 Expected results: Broader ranking for related search queries.

Tactic 4.2: A/B Testing Thumbnails

Why this works: Different images perform differently. Testing can improve click-through rates from image search and product pages.

Exactly how to do it:

1. Use A/B testing tools for product thumbnails.
2. Test different angles, backgrounds, and lighting.
3. Measure click-through rate and conversion rate.
4. Implement winning variant site-wide.
5. Iterate continuously.

📊 Expected results: Up to 25% improvement in click-through rates.

Tactic 4.3: Leveraging Google Lens and Visual Search

Why this works: Google Lens allows users to search with images. Optimising for visual search can capture emerging traffic.

Exactly how to do it:

1. Ensure images are high-resolution and have clear subjects.
2. Use descriptive alt text and metadata.
3. Submit images to Google Merchant Center if applicable.
4. Encourage user-generated content with images.

📊 Expected results: First-mover advantage in visual search.
