Pros & Cons
theimageoptimizer
Pros
No account required to use the standalone web-based image compressor
States that uploaded images are never stored on its servers
Pay-as-you-go credits never expire, alongside monthly Standard/Agency plans
Dedicated Agency plan with multi-license management and consolidated billing for agencies managing several sites
Automatically converts images to modern WebP/AVIF formats
Cons
Paid use of the WordPress plugin and higher-volume compression relies on a credit-based license system rather than a flat subscription
Specific compression algorithm and quality-level details are not published on the site
No manual control over compression level is mentioned — format/quality selection is automatic
stratisilo
Pros
Purpose-built for WooCommerce category pages rather than being a generic all-purpose SEO plugin
Free version on WordPress.org lets store owners try the core silo-building features before paying
Built to work with popular themes (Kadence, Astra, OceanWP, GeneratePress, Storefront) and alongside Yoast SEO and Rank Math
Agency plan (up to 25 sites, white-label) makes it practical for SEO consultants managing multiple client stores
Cons
Narrowly focused on WooCommerce category-page structure, not a full-site or general SEO solution
Pro and Agency features require an active $49/year or $149/year license; deactivating the license removes those features (though content and settings are preserved)
The 200-340% organic traffic increase figures cited on the site come from the vendor's own case studies, not independent verification
