Our Verdict
If a merchant is struggling with Google Search Console errors related to structured data or wants to improve their rich snippets, SA SEO JSON-LD Schema markup might be beneficial, especially if they have some familiarity with schema markup. However, the low rating and small number of reviews should be a significant consideration. On the other hand, if a merchant wants an easy, automated way to optimize images for faster loading times and better SEO, SEO Speed Image Optimizer is the better choice. The high rating and large number of reviews suggest a reliable and effective app for image optimization.
For most merchants in 2026, SEO Speed Image Optimizer will likely provide a more immediate and tangible benefit due to the significant impact of page speed on SEO and user experience. Unless the merchant specifically needs to address structured data issues or desires more control over schema markup, SEO Speed Image Optimizer presents a more compelling and proven solution.
