Product review and recommendation websites face a unique challenge: they need to display hundreds of icons, badges, and graphics while maintaining lightning-fast load times. When users browse gift guides, comparison charts, or product catalogs, every millisecond of delay costs conversions.
In this guide, we'll show you exactly which elements to convert to SVG, how to implement them properly, and share real-world examples from successful product sites that have achieved dramatic performance gains.
Why Performance Matters for Product Sites
of mobile users abandon sites that take over 3 seconds to load
lost annually by e-commerce due to slow page speeds
increase in conversions for every 1-second improvement
Product review sites see 60-70% of their traffic from mobile devices. Users are often browsing on the go - searching for gift ideas while commuting, comparing products during lunch breaks, or checking reviews before making in-store purchases.
These users are typically on variable network conditions. A page that loads quickly on WiFi might take 8+ seconds on a 3G connection. SVG graphics are particularly valuable here because they compress extremely well and render instantly once downloaded.
What Should Be SVG (And What Shouldn't)
Rating Stars & Review Icons
These appear dozens of times per page. SVG stars render crisply at any size and can be styled with CSS for hover states.
Category Icons
Backpacks, electronics, accessories, clothing - each category needs an icon. One SVG sprite sheet can replace 20+ PNG files.
Trust Badges & Certifications
"Expert Reviewed", "Best Value", "Editor's Choice" - these badges build trust and should be crisp on all devices.
Feature Icons
"Waterproof", "Lightweight", "TSA Approved" - product feature indicators that appear on every product card.
Navigation & UI Elements
Search icons, menu toggles, arrows, social media icons - all essential UI elements.
| Asset Type | PNG Size | SVG Size | Savings |
|---|---|---|---|
| Rating Stars | 12 KB | 0.4 KB | 97% |
| Category Icons (x20) | 180 KB | 8 KB | 96% |
| Trust Badges (x5) | 45 KB | 3 KB | 93% |
| Navigation Icons | 24 KB | 2 KB | 92% |
| Social Proof Icons | 36 KB | 2.5 KB | 93% |
| Total | 297 KB | 15.9 KB | 95% |
Real-World Examples
Sites like TravelGiftList.com, which curate hundreds of travel products across categories like luggage, electronics, and accessories, can see massive performance gains from SVG optimization. These sites typically display:
- 20+ category icons (backpacks, cameras, travel pillows, etc.)
- Star ratings on every product (5-10 instances per card)
- Trust badges like "Expert Reviewed" and "Best Value"
- Feature icons for product attributes
Price comparison and deal sites often show dozens of products per page, each with multiple icons for shipping status, price alerts, and retailer logos.
Before SVG Optimization
- Page weight: 2.4 MB
- Load time (3G): 8.2 seconds
- LCP score: Poor
After SVG Optimization
- Page weight: 890 KB
- Load time (3G): 3.1 seconds
- LCP score: Good
Sites that compile expert reviews need to balance rich content with fast loading. Key SVG opportunities include:
- Verdict badges (Best Overall, Best Budget, Editor's Choice)
- Pro/con indicator icons
- Comparison chart icons
- Section navigation icons
Implementation Guide
Before converting, audit your site to identify all icon assets:
// Open DevTools > Network > Filter by "img" // Look for files under 50KB - these are likely icon candidates // Or use this command to find PNGs under 50KB: find . -name "*.png" -size -50k -type f
Focus on icons that appear multiple times across your site - these offer the biggest cumulative savings.
Use an AI-powered converter for best results with complex icons. For simple shapes, manual tracing in Figma or Illustrator works well.
Conversion Tips:
- 1. Start with your highest-resolution PNG source
- 2. Remove unnecessary metadata after conversion
- 3. Optimize paths using SVGO or similar tools
- 4. Test at multiple sizes to ensure quality
For maximum efficiency, combine all icons into a single sprite sheet:
<!-- Define sprites once in your HTML -->
<svg style="display: none;">
<symbol id="icon-star" viewBox="0 0 24 24">
<path d="M12 2l3.09 6.26L22 9.27l-5 4.87..."/>
</symbol>
<symbol id="icon-check" viewBox="0 0 24 24">
<path d="M9 16.17L4.83 12l-1.42 1.41L9 19..."/>
</symbol>
</svg>
<!-- Use icons anywhere -->
<svg class="icon"><use href="#icon-star"/></svg>One major advantage of SVG: you can style icons with CSS, enabling hover states, dark mode, and dynamic colors:
.icon {
width: 24px;
height: 24px;
fill: currentColor; /* Inherits text color */
transition: fill 0.2s ease;
}
.icon:hover {
fill: var(--primary-color);
}
/* Dark mode support */
@media (prefers-color-scheme: dark) {
.icon {
fill: #ffffff;
}
}Common Mistakes to Avoid
Converting Product Photos to SVG
SVG is for graphics, not photographs. Converting a product photo to SVG creates a massive file that looks worse than the original JPEG. Keep product images as WebP/JPEG.
Not Optimizing SVG Files
Raw SVG exports from design tools often contain unnecessary metadata, comments, and precision. Always run SVGs through SVGO or a similar optimizer.
Using Inline SVG for Everything
While inline SVG enables CSS styling, embedding the same icon 50 times bloats your HTML. Use sprite sheets or symbol references for repeated icons.
Forgetting Accessibility
SVG icons need proper aria labels or title elements for screen readers. Decorative icons should have aria-hidden="true".
