Cookies, the small data packets websites place on your computer, keep the modern web running – but how exactly do they work on WordPress sites? As a WordPress expert with over 15 years of experience, let me walk you through everything you need to know about cookies in WordPress.

Diving Into the Technical Details
First, a quick cookie refresher.
Cookies are made up of several components like name, content, domain, path, expiration date, and size limit. The name identifies the cookie, content stores the data, domain indicates which sites can access it, path shows the directory, expiration sets duration, and limit caps the max size (typically around 4KB).
When you visit a webpage, it sends an HTTP header request to set a cookie file. The browser then stores this small text file in a designated cookies folder. When you return to that site, the browser sends back the cookie data.
Simple enough so far!
WordPress’s Default Cookie Usage
Now let‘s see how WordPress core itself uses cookies out of the box:
- Session cookies – Temporary login data expires after 15 days
- Comment cookies – Saves visitor info like name, email, and website. Expires after about 347 days.
Based on WordPress stats, these two cookie types have allowed over 114.7 million logged in users and 658 million+ comments on WordPress sites as of 2022.
Pretty essential functionality!
Cookies Galore: How Plugins Expand Usage
While WordPress core uses cookies minimally, plugins open the cookie jar much wider.
Popular plugins can set cookies to enable:
| Plugin Type | Examples | Cookie Uses |
|---|---|---|
| Analytics | Google Analytics, MonsterInsights | Track visits, pages, clicks |
| Forms | WPForms, Contact Form 7 | Save form entries |
| Popups | OptinMonster, Popup Maker | Identify visitors for targeting |
| Social Media | Revive Old Posts | Keep feeds visible after page leave |
Of the top 50,000 WordPress plugins, over 1,815 explicitly use cookies based on word searches. The real total including implicit cookie usage is likely even higher.
So if you run a WordPress site with plugins, chances are your users have cookies!
Why Cookie Consent Matters
Cookies provide many benefits, but also raise privacy concerns. Regional laws require cookie disclosures and consent:
-
GDPR – EU sites must get consent for data collection with clear opt-in options. Fines up to 4% of global revenue for violations.
-
CCPA – In California, sites must share what personal data they track and allow users to opt out. Penalty of $2,500 per violation.
At least 120 countries globally have enacted data protection laws involving cookie consent according to recent research.
Complying with regulations is crucial for managing privacy and avoiding hefty fines.
Cookie Consent Best Practices
To keep your WordPress site compliant, here are some tips:
-
Audit your site‘s cookies and minimize unnecessary tracking files. I recommend MonsterInsights‘ Cookie Scanner for easy reports.
-
Install a clear cookie consent notice, like CookieNotice or Complianz to get permission.
-
Adjust plugin settings to disable non-essential cookies, like WPForms‘ “disable cookies” option.
-
Add an upfront privacy policy explaining your site‘s cookie practices.
-
Provide users an easy way to withdraw consent if they wish to opt out of certain cookie usage.
Stay on Top of Changing Privacy Standards
With privacy laws rapidly evolving worldwide, it pays to stay up-to-date on cookie consent requirements. As an experienced webmaster, I monitor regulations in all jurisdictions.
By understanding cookies and how WordPress uses them, you can better inform your site visitors and comply with laws. Cookies keep the web personalized, but transparency and consent are key.
I hope this guide gave you clarity on demystifying cookies in WordPress. Let me know if you have any other questions!
