The Short Answer: Yes
If your blog:
- Uses Google Analytics, Google Ads, or any analytics tool
- Has a contact form, email signup, or comment section
- Collects email addresses for a newsletter
- Uses cookies or tracking pixels
- Displays ads or monetises content in any way
Then yes, you legally need a Privacy Policy under the Australian Privacy Act 1988, even if you make zero dollars from your blog.
The Privacy Act applies whenever you collect personal data. Email addresses and IP addresses are personal data. If your blog collects either, you need a Privacy Policy.
Why Google AdSense & Google Analytics Require One
If you monetise your blog with Google AdSense or use Google Analytics (which is free and used by ~87% of websites), you're contractually required to have a Privacy Policy.
From Google AdSense Terms: "You must have a clear, comprehensive, and accurate privacy policy."
From Google Analytics Terms: "You will comply with all applicable laws regarding the collection of information from visitors."
Google's terms require your Privacy Policy to disclose:
- You use Google Analytics (or whichever Google tool you use)
- It collects IP addresses and browsing behaviour
- It sets cookies
- A link to Google's Privacy Policy
Not disclosing this violates both the Privacy Act and Google's Terms. Google can suspend or ban your AdSense account if your Privacy Policy is missing or inaccurate.
Monetisation Triggers Additional Disclosure Requirements
If you make any money from your blog, you have extra privacy obligations:
Google AdSense
Disclose: "This site uses Google AdSense to display ads. Google may set cookies on your device to show you personalised ads based on your browsing history."
Affiliate Links
If you earn commissions from affiliate links (Amazon, Affiliate Networks, etc.), disclose this. Note: this is separate from privacy law (it's FTC/ACCC regulation), but often goes in a Privacy Policy or separate disclosure.
Example: "This site contains affiliate links. We may earn a commission if you click and purchase through our links."
Sponsored Posts
If you receive payment for sponsored content, disclose how you handle the sponsor's data. Do they provide a tracking pixel? Do you collect their visitor data?
Email Newsletter Signup: What Must Be Disclosed
If you collect email addresses for a newsletter, your Privacy Policy must address:
Email Service Provider
Which platform do you use? Mailchimp, ConvertKit, Substack, Brevo, EmailOctopus? Disclose it:
"We use [Platform Name] to manage our newsletter. Your email is stored with [Platform Name], which has its own Privacy Policy."
Consent & Unsubscribe
Under the Spam Act 2003, you must have express consent before sending marketing emails. Disclose how subscribers opt in:
"By subscribing, you consent to receive weekly emails. You can unsubscribe at any time by clicking 'Unsubscribe' at the bottom of any email."
Data Retention
How long do you keep subscriber emails? If someone unsubscribes, how long before you fully delete them?
Comment Sections: What Data They Collect
If your blog allows comments, commenters are providing personal data (name, email, sometimes website URL, IP address). Your Privacy Policy must disclose:
- What data is collected: Name, email, URL, comment text, IP address, timestamp
- Why you collect it: "To display comments and prevent spam"
- Who can see it: "Commenter name and URL are public; email is not displayed publicly but stored for moderation"
- How long you keep it: "Comments are kept as long as the blog post exists"
- The comment platform: If using Disqus, Commento, or another third-party service, link to their privacy policy
Embedded Social Media Widgets & Third-Party Data
If you embed social media widgets (Instagram feed, Facebook feed, Twitter timeline, YouTube videos), you're allowing those platforms to collect visitor data:
- Facebook feed: Sets Facebook cookies, collects visitor data, allows Facebook to build profiles
- Instagram embed: Similar to Facebook
- YouTube videos: YouTube sets cookies and tracks viewers
- Twitter/X timeline: Sets cookies and tracks visitors
Your Privacy Policy must disclose these third-party data collectors and link to their privacy policies.
Cookies & Cookie Disclosure
Australia doesn't have a mandatory cookie law like GDPR, but good practice is to disclose your cookie use:
Essential Cookies
For site function (e.g., session cookies, login cookies) — no consent needed, but disclose them
Analytics Cookies
From Google Analytics, Hotjar, etc. — disclose that they're used to understand visitor behaviour
Marketing Cookies
From retargeting pixels (Meta Pixel, Google Ads, etc.) — disclose that they're used for ad targeting
Third-Party Cookies
From embedded widgets (social, ads, video players) — disclose that third parties set cookies on your blog
Many bloggers use a simple statement like: "This site uses Google Analytics cookies to understand visitor behaviour. We also use Meta Pixel for retargeting."
What Your Blog's Privacy Policy Must Include
- Your name/blog name and contact email
- What data you collect: Visitor IP addresses (from Analytics), email (from newsletter signup), commenter details (from comments), cookies
- All third-party tools: Google Analytics, Google AdSense, email service (Mailchimp, etc.), comment platform (if not native), social widgets

- How long you keep it: "Analytics data is kept for 26 months (Google default). Newsletter emails are kept until unsubscribe."
- Cookie disclosure: What cookies you use and why
- Links to third-party privacy policies: Google, your email service, etc.
- User rights: How readers can access, correct, or delete their data (via privacy@yourblog.com)
