Adding Google Maps Embed API to Your HTML
- Create the HTML file in which you want to embed Google Maps. You can use standard HTML5 structure to do this.
- Insert an
<iframe>
tag in your HTML where you want the map to be displayed. The Google Maps Embed API provides you with a URL that you can directly place within the src
attribute of this <iframe>
tag.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Google Map Embed</title>
</head>
<body>
<h1>Our Location</h1>
<iframe
width="600"
height="450"
style="border:0"
loading="lazy"
allowfullscreen
referrerpolicy="no-referrer-when-downgrade"
src="https://www.google.com/maps/embed/v1/place?key=YOUR_API_KEY&q=Space+Needle,Seattle+WA">
</iframe>
</body>
</html>
Preparing the URL for the <iframe>
- Start with the base URL:
https://www.google.com/maps/embed/v1/place?
- Append your API key, using the
key
parameter. It's crucial to replace YOUR_API_KEY
with your actual API key obtained from the Google Cloud Platform.
- Add the
q
parameter to define the query for the map, which can be an address or any place identifier.
Customize the Appearance
- You can adjust the width and height attributes to fit the desired dimensions within your website layout. It's common to use percentages for responsive layouts, such as
width="100%"
.
- The
style
attribute can be used to apply custom CSS styles. Consider adding max-width
for responsiveness or changing borders as necessary.
Optimize for Performance
- Use the
loading="lazy"
attribute to delay loading the map until the user scrolls near the viewport, improving page load speed.
- Minimize the usage of multiple embedded maps on the same page, as each instance increases data requests and affects performance.
Restricting API Key Usage
- Navigate to the Google Cloud Console, where your project is hosted.
- Locate the API key management section, and under the key restrictions, set the HTTP referrers to only allow requests from your web domain. This minimizes unauthorized usage.
- For added security, enable billing alerts in the Google Cloud Console to help monitor any unexpected increases in API usage.
Monitoring and Maintenance
- Regularly check the API usage statistics provided in the Google Cloud Console to ensure your usage remains within free tier limits, if applicable.
- Keep your API key secured and periodically rotated to prevent misuse. Avoid exposing the API key in client-side code repositories publicly.
