JSON‑LD Express for SEO Schema vs SEO Speed Image Optimizerfor Shopify (2026)
JSON‑LD Express for SEO Schema and SEO Speed Image Optimizer are both Shopify apps in the SEO category, but they address fundamentally different aspects of search engine optimization. JSON‑LD Express focuses on structured data, helping merchants implement JSON-LD schema markups to improve their store's rich snippet eligibility and visibility in Google SERP results. Its strength lies in its automated schema generation, particularly for product data. SEO Speed Image Optimizer, on the other hand, tackles image optimization. It helps merchants compress and resize images for faster loading times, optimize alt text for improved accessibility and SEO, and offers bulk image editing features. The primary difference lies in their SEO focus. JSON-LD Express targets technical SEO by ensuring structured data compliance, making it beneficial for stores wanting to improve their search engine understanding of product data. SEO Speed Image Optimizer concentrates on on-page SEO and site speed optimization, improving user experience and search engine rankings through optimized images. This makes the latter potentially more beneficial for a broader range of merchants concerned with overall site performance, while the former is ideal for merchants particularly focused on rich snippets for products.
