Code Review Summary
This PR adds Google Analytics tracking to the blog, but contains several critical security and privacy issues that must be addressed before merge:
Critical Issues:
- Security Risk: Hardcoded Google Analytics tracking ID exposes sensitive configuration data
- Privacy Violation: Analytics tracking without user consent violates privacy regulations (GDPR, CCPA)
- Code Quality: Inconsistent indentation mixing tabs and spaces
Required Actions:
- Move the tracking ID to Jekyll configuration (
_config.yml) usinggoogle_analytics_idvariable - Implement user consent mechanism or add privacy policy disclosure
- Fix indentation consistency throughout the JavaScript code
- Add newline at end of file
The Google Analytics implementation itself is functionally correct, but the security and privacy concerns must be resolved before this can be safely deployed to production.

Code Review
This pull request enables Google Analytics. I've identified a couple of areas for improvement. The analytics script contains a hardcoded tracking ID and ignores the anonymize_ip setting from your configuration; I've suggested using the variables from _config.yml instead. I also noted that analytics is only enabled for the homepage and suggested moving the include to a more general layout for site-wide tracking, potentially leveraging the built-in analytics feature of your Jekyll theme.

The Google Analytics tracking ID G-4DG3HSBT1T is hardcoded in this file. It's better to use the value from _config.yml (site.analytics.google.tracking_id) to avoid duplication and make maintenance easier. Additionally, the anonymize_ip: true setting in your _config.yml is currently being ignored. The suggested code below reads these values from your configuration file.

By including the Google Analytics script only in the home layout, you will only track visits to your homepage. Any visitors landing directly on other pages (like blog posts) will not be tracked. For site-wide tracking, this include should be placed in a more general layout file that all pages use, such as _layouts/default.html or _layouts/archive.html.
It's also worth noting that the minimal-mistakes-jekyll theme has built-in support for Google Analytics, which you've already configured in _config.yml. You might be able to simply use {% include analytics.html %} in your base layout and remove the custom _includes/google-analytics.html file, letting the theme handle the implementation.

The Google Analytics tracking ID is hardcoded in this template. This creates a maintainability issue as the ID appears both here and in _config.yml (lines 17-21). The tracking ID should be read from the site configuration using Liquid templating to maintain a single source of truth. Use site.analytics.google.tracking_id to reference the value from _config.yml.

The Google Analytics include should be placed in the head section of the document (typically in the archive layout or a head include), not in the body of the home.html layout. Google Analytics scripts should be loaded in the head for proper tracking initialization before page content renders. Additionally, this implementation only adds tracking to the home page, but analytics should be site-wide. Consider adding the include to the archive layout or a shared head include that's used across all pages.

Inconsistent indentation: The function declaration uses spaces for indentation while the rest of the script uses tabs. This should be standardized to match the project's coding style. Either use all tabs or all spaces throughout the script.

Code Review
This pull request enables Google Analytics by adding custom tracking scripts. While this approach works, the minimal-mistakes-jekyll theme you're using provides built-in support for Google Analytics, which is configured via _config.yml. You have already correctly configured the necessary settings. Therefore, adding these new files (_includes/google-analytics.html and _includes/head/custom.html) is likely redundant. The theme's built-in implementation also correctly handles settings like anonymize_ip.
I recommend removing the two files added in this PR and letting the theme manage the analytics integration. This will simplify your project and make it easier to maintain.
However, if you have a specific reason to use a custom implementation, I have provided a comment with a suggested improvement to your script to make it more robust and to respect the privacy settings in your configuration.

This analytics script can be improved in two ways:
- Respect
anonymize_ipsetting: Your_config.ymlhasanonymize_ip: true, but this script doesn't apply it. This is important for user privacy. - Add robustness check: The script should only be rendered if a
tracking_idis present in the configuration to avoid errors.
The suggested code below addresses both points by wrapping the script in a conditional and adding the anonymize_ip parameter.

The configuration file specifies anonymize_ip: true, but this setting is not being applied in the Google Analytics implementation. The gtag config call needs to include the anonymize_ip parameter to respect the privacy setting defined in the configuration. Without this, IP addresses will not be anonymized despite the configuration setting.

The Google Analytics tracking code is being included unconditionally without checking if analytics is enabled or if a tracking ID is configured. Consider wrapping the analytics code in a conditional check to only load when the tracking_id is present. This prevents loading tracking scripts unnecessarily and improves privacy.

The configuration in _config.yml specifies provider: "google-gtag" which suggests the minimal-mistakes theme may already have built-in Google Analytics support. Creating a custom implementation might result in duplicate tracking scripts being loaded if the theme's built-in analytics are also active. Consider verifying whether the theme's native analytics integration should be used instead, or ensure the theme's built-in analytics are disabled to prevent double-tracking.

The anonymize_ip option is configured both in _config.yml (line 21) and hardcoded here. This creates a maintenance issue where the configuration exists in two places. Consider using the config value: {{ site.analytics.google.anonymize_ip }} instead of hardcoding true to maintain a single source of truth.

This pull request introduces a custom implementation for Google Analytics. However, the minimal-mistakes-jekyll theme provides built-in support for Google Analytics, which is activated via _config.yml. Since your configuration file already seems to be set up for this, the files added in this PR are likely redundant. This can lead to the Google Analytics script being loaded twice, which would skew your tracking data. I recommend removing the newly added files (_includes/google-analytics.html and _includes/head/custom.html) and relying on the theme's native integration.

The minimal-mistakes-jekyll theme automatically includes the Google Analytics script based on the configuration in _config.yml. Including it again here via _includes/head/custom.html is redundant and will likely cause the script to be loaded twice, which can corrupt your analytics data. It's recommended to remove this file and _includes/google-analytics.html to rely on the theme's built-in functionality.

This line hardcodes the anonymize_ip option. The theme's built-in implementation handles this more flexibly by checking the site.analytics.google.anonymize_ip setting from _config.yml. This makes the theme's version more maintainable, as configuration changes only need to be made in one place. This is another reason to prefer the theme's native analytics integration over a custom implementation.
