Reviews
what people actually saySeraphinite Accelerator is a speed optimization plugin with a loyal base of users who praise its simplicity and real-world performance gains, but it draws serious recurring criticism around stale cache management, theme compatibility breakage, and at least one credible report of SEO damage — alongside some extreme unverified allegations that should be weighed cautiously.
