Why Extra Text Appears in Your Calendar Embed
Here's what's actually happening behind the scenes: when HTML code or random text displays where your calendar booking form should appear, it's rarely a GoHighLevel problem. More often, it's one of three things:
1. Your website builder isn't recognizing the embed code format. GoHighLevel generates embed code in JavaScript format. If you paste this into a plain text field instead of a custom code block, your website will literally display the code as text instead of executing it.
2. A caching or CDN issue is serving stale content. Browsers and content delivery networks sometimes cache old versions of your page. The calendar embed code was removed, but your visitor's browser still sees the original HTML.
3. Third-party scripts or plugins are interfering. Security plugins, form builders, or poorly configured scripts can strip out or conflict with GoHighLevel's embed code before your visitors ever see it.
4. The embed code itself was copied incompletely or corrupted. This happens more than you'd think, especially when copying from mobile devices or email.
The key takeaway: GoHighLevel's embed code is secure by design. It doesn't inject malware or compromise SEO. It's a simple JavaScript snippet that loads your calendar in an iframe—clean, lightweight, and sandbox-protected.
💡 Pro Tip
Before you start troubleshooting, open your website in an incognito/private browser window. This bypasses cached versions and tells you if the issue is real or just a caching artifact.
How to Verify Your Embed Code Is Clean and Secure
The embed code GoHighLevel generates is standardized and safe. Here's how to verify yours:
Step 1: Locate Your Embed Code
In GoHighLevel, navigate to Calendars → Calendar Settings. Find the calendar you want to embed and click the three-dot menu. Select Share, then click the Embed Code tab. Click Copy.
Step 2: Check the Code Format
Your embed code should look like this:
<script src="https://[your-gohighlevel-domain]/embeds/[calendar-id]"></script>
Notice: no hidden text, no extra HTML, no suspicious parameters. Just a clean script reference pointing to GoHighLevel's secure servers.
Step 3: Test in Your Browser Console
Paste your code into a webpage, open the browser inspector (F12 or Right Click → Inspect), go to the Console tab, and look for errors. You should see no red errors related to the GoHighLevel script—only a successful load message.

Step-by-Step Troubleshooting Guide
Troubleshooting Flow:
Issue: You see HTML code on your live website
Fix #1: Use a Custom Code Block, Not a Text Block
- Webflow: Add an Embed element (not text), paste code, publish
- Wix: Add HTML element from Apps, paste code
- WordPress: Use a Custom HTML block, not a Paragraph block
- Squarespace: Use Code Block from the Insert menu
Fix #2: Clear Browser Cache and Hard Refresh
- Windows: Ctrl + Shift + Delete (open cache settings), clear all
- Mac: Cmd + Shift + Delete, clear all
- Hard refresh: Ctrl + F5 (Windows) or Cmd + Shift + R (Mac)
Fix #3: Re-Copy and Re-Paste Your Embed Code
- Go back to GoHighLevel Calendars settings
- Click the three-dot menu and select Share
- Copy the entire Embed Code tab content again
- Delete the old code from your website
- Paste the fresh code into the custom code block
- Save and publish
Fix #4: Disable Conflicting Plugins (WordPress Only)
- Deactivate security and caching plugins one by one
- Test the calendar after each deactivation
- Common culprits: Wordfence, Sucuri, WP Super Cache
- Re-enable the plugins once you identify the conflict, then whitelist GoHighLevel's domain in the plugin settings
Fix #5: Check for Content Security Policy (CSP) Headers
If you have a technical team, ask them to check your site's CSP headers. GoHighLevel's embed needs permission to load external scripts. You may need to add https://*.gohighlevel.com to your CSP whitelist.
Embedding Calendars Without Compromising SEO
One worry I hear constantly: "Won't embedding JavaScript hurt my SEO?" The answer is no—when done right.
Why GoHighLevel Embeds Are SEO-Safe:
- It's an iframe, not inline content. Google crawls it, but it doesn't affect your page's text content or keyword density
- It doesn't hide text from search engines. The script loads transparently; no cloaking
- It's hosted on GoHighLevel's secure domain. No sketchy redirects or spam signals
- Page speed impact is minimal. Modern browsers load it asynchronously
Best Practices to Maintain SEO:
- Keep your page's main content intact. Don't replace your entire page with just a calendar embed
- Write descriptive text above the calendar. Something like: "Schedule a free 30-minute consultation with our team using the calendar below."
- Use a meaningful page title and meta description. Example: "Book Your Free Consultation — [Your Business Name]"
- Make sure the page loads fast. Test with Google PageSpeed Insights; if scores drop below 50, investigate other elements on the page
Best Practices for Clean Calendar Embeds
Implementation Checklist:
- ✅ Use a dedicated booking or consultation page for your calendar, not your homepage
- ✅ Test on desktop and mobile before going live
- ✅ Monitor your calendar page monthly for layout shifts or broken embeds
- ✅ Set time zone correctly in GoHighLevel Calendar Settings to avoid booking confusion
- ✅ Configure availability in advance so no double-bookings occur
- ✅ Use a descriptive calendar name if you're embedding multiple calendars
💡 Pro Tip
If you embed multiple calendars on the same page, each one gets its own script tag. Make sure you copy each one separately from GoHighLevel—don't manually combine them.
The bottom line: calendar embed issues are almost always fixable with the steps above. They're rarely a GoHighLevel security issue and almost never an SEO problem. The real culprit is usually a mismatch between your website platform and how you're pasting the code.
