Step by Step Implementation

1. 1

   Step 1:

   1.

   Log into your Squarespace dashboard and go to Settings > Advanced > Code Injection.

   This fix takes about 30 minutes with admin access to Squarespace.

   Backup your site first by duplicating the homepage to avoid any issues.
2. 2

   Step 2:

   2.

   In the Header section of Code Injection, add code to preload your hero image.

   Paste this: <link rel='preload' href='your-hero-image.jpg' as='image'>.

   Squarespace will fetch it early so mobile users see content faster.
3. 3

   Step 3:

   3.

   Open your homepage editor in Squarespace and select image blocks.

   Turn on lazy loading if it's an option there.

   Compress images to under 100KB using a free tool like TinyPNG before uploading back to Squarespace.
4. 4

   Step 4:

   4.

   Go to Design > Custom CSS in your Squarespace dashboard.

   Add this rule: .hero img { max-width: 100%; height: auto; }.

   It resizes the hero image for mobile without losing quality.
5. 5

   Step 5:

   5.

   Check Connected Accounts in Squarespace settings and disconnect unused apps.

   These extra scripts slow down LCP on mobile.

   Test one at a time to keep your site running smoothly.
6. 6

   Step 6:

   6.

   Save all changes and use Squarespace's mobile preview feature.

   Republish the site to clear any cache.

   Watch for faster hero image loading on your phone.
7. 7

   Step 7:

   7.

   After 24 hours, run a mobile test in Google PageSpeed Insights.

   Check if LCP is below 4 seconds first.

   Keep tweaking until it's under 2.5 seconds.

Step by Step Implementation

1. 1

   Step 1:

   1.

   Log into your Squarespace dashboard and create a full backup.

   This fix needs about 50 minutes of admin time.

   Go to Settings > Backups to save everything safely.
2. 2

   Step 2:

   2.

   Go to Settings > Advanced > Code Injection and review all scripts.

   Add 'defer' to non-critical JS tags like <script defer src='...'>.

   This stops them from blocking interactivity in Squarespace.
3. 3

   Step 3:

   3.

   Edit your homepage in the Squarespace page editor.

   Remove heavy blocks like carousels and replace with static images.

   Fewer elements mean faster loading for mobile users.
4. 4

   Step 4:

   4.

   In Design > Custom CSS, add body { font-family: system-ui; }.

   This uses built-in phone fonts so Squarespace skips extra downloads.

   It speeds up when users can tap buttons.
5. 5

   Step 5:

   5.

   Visit Connected Accounts in Squarespace and turn off unused analytics or marketing tools.

   These often delay TTI with extra code.

   Confirm your site still works after each change.
6. 6

   Step 6:

   6.

   Add a code block for below-the-fold scripts and lazy load them on scroll.

   Squarespace lets you paste simple JS for this.

   Test on mobile to ensure smooth interactions.
7. 7

   Step 7:

   7.

   Preview on a mobile device and tap buttons right away.

   They should respond in under 2 seconds.

   Make small tweaks if needed.
8. 8

   Step 8:

   8.

   Republish and retest with PageSpeed Insights after a day.

3. 3

   Step 3:

   3.

   Go to Design > Custom CSS and hide non-essential elements.

   Add #above-fold-extra { display: none; opacity: 0; }.

   Reveal them later with simple JavaScript in Squarespace.
4. 4

   Step 4:

   4.

   In Settings > Advanced > Code Injection, add 'async' to analytics script tags.

   This lets Squarespace load them without slowing FCP.

   Paste the updated tags in Footer.
5. 5

   Step 5:

   5.

   Open Site Styles in Squarespace and limit fonts to two types.

   Switch to system fonts like Arial where possible.

   Subset custom fonts to shrink file sizes.
6. 6

   Step 6:

   6.

   Compress above-fold images using Squarespace's tools or TinyPNG.
