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
Yoast SEO
Pros
Deep integration with the WordPress editor gives instant, actionable feedback while content is being written
The free version already covers core SEO fundamentals most small sites need: sitemaps, schema and content analysis
Large support community, extensive documentation and frequent updates aligned with WordPress core changes
Premium automation, such as redirects, internal linking suggestions and AI snippets, addresses genuine time-saving needs
Trusted at scale, with millions of active installs, so it is well tested against WordPress and search engine changes
Cons
Premium is licensed per site, so agencies managing many WordPress properties face a recurring cost per domain
Redirect management, internal linking suggestions and AI snippet generation are all locked behind the paid tier
Advanced SEOs sometimes find the analysis rules too rigid for content that intentionally breaks conventional structure
Only works within WordPress, so it offers no value outside that specific CMS ecosystem
