    Some advanced optimization features might require a level of technical knowledge to configure correctly, which can be challenging for non-technical users.
  • Risk of Breaking Site Layouts
    Improper configuration of Autoptimize can lead to broken website layouts, as optimizations may inadvertently change the way CSS or JavaScript renders on the site.
  • Limited Image Optimization
    While Autoptimize focuses on HTML, CSS, and JavaScript, it offers limited support for image optimization compared to dedicated image optimization plugins.
  • Inconsistent Support
    Users might experience inconsistencies in getting timely support or updates, especially if they are using the free version, which can slow down the resolution of issues.

  • I have no clue how to optimize my PageSpeed
    The issues your site are having are troublesome for most small site administrators: good score on Desktop load but lousy on Mobile load. There are also good paid options for someone to professionally optimize the site using the above plugins (e.g. link), but do due dillgence before you hand over the keys (admin login) to any budget service to work on your WordPress installation, as it can end in tears.
