Why Accordions Boost User Retention and SEO

  • Improved Dwell Time: Users must actively click to read hidden content, which counts as engagement and increases time spent on the page.
  • Content Density: You can include extensive troubleshooting or FAQ sections without making the page look overwhelmingly long, leading to better perceived readability.
  • Schema Advantage: The structure is ideal for inserting FAQ Schema (rich snippets), helping your page take up more real estate on Google Search results.
