<h4>WooCommerce’s Default Search Costs You Sales</h4>
Your customers search for “blue running shoes” and get irrelevant results. They search “iphne case” with a typo and get nothing. 80% of shoppers leave after a bad search experience — and WooCommerce’s built-in search only matches exact title keywords.
Contexa fixes this. It understands what your customers mean, not just what they type.
<h4>How Contexa Is Different</h4>
<ul>
<li>AI-Powered Semantic Search — Understands intent, not just keywords. “Laptop bag” finds “notebook carrying case” too</li>
<li>Typo Tolerance — “snekers” still finds sneakers. Works across 100+ languages including Hebrew, Arabic, and English</li>
<li>Instant Autocomplete — Suggestions appear as customers type, based on your store’s actual search history</li>
<li>Sub-2-Second Results — Direct API with client-side rendering. No server load on your WordPress hosting</li>
<li>5 Recommendation Engines — Similar products, trending, personalized, frequently bought together, and cart-based upsells</li>
<li>AJAX Add to Cart — Customers add to cart without page refresh, with quantity selectors</li>
<li>5 Visual Templates — Classic, minimal, shadow, bordered, and gradient styles in list or grid layouts</li>
<li>WooCommerce Native — Automatic currency detection, stock status, and product sync</li>
<li>WPML Support — Full multilingual search with language-specific content sync</li>
<li>Content Search — Search blog posts, pages, and custom post types alongside products</li>
<li>Order Tracking — Track which searches lead to purchases. See your search-driven revenue</li>
<li>Easy Setup — Install, enter API key, sync products. Working search in under 5 minutes</li>
</ul>
