Ever wondered why a flight or a product suddenly becomes more expensive the second time you check it? Or why your friend gets a cheaper deal for the same service on the same website? The answer lies in dynamic pricing based on browser history. Companies are using your online behaviour to personalise prices—and not always to your benefit.

What is Dynamic Pricing?

Dynamic pricing is a strategy where businesses adjust the cost of a product or service in real-time based on various factors, such as demand, competitor pricing, and—most controversially—your browsing history. While it’s a legitimate strategy for businesses to optimise profits, it often leaves customers feeling cheated, especially when they realise their previous online activity influenced the price.

How Does Your Browser History Affect Pricing?

Websites track your browsing habits using cookies, scripts, and tracking pixels. Here’s how it works:

1. Cookies and Tracking Pixels: When you visit a site, it places cookies in your browser, storing data such as your previous visits, search queries, and time spent on specific pages.

2. Return Visits: If you revisit a website, its algorithms may detect your increased interest and raise prices, knowing you’re more likely to buy.

3. Competitor Searches: Visiting competing websites could signal that you’re price-shopping, leading to either discounts to win your purchase—or higher prices based on perceived urgency.

Industries Leveraging Dynamic Pricing

Dynamic pricing based on browser history is especially prevalent in:

• Travel: Airlines, hotels, and car rental services frequently adjust rates based on search patterns.

• E-commerce: Retailers use it to upsell or push you toward pricier products.

• Ride-Sharing Apps: Surge pricing is a form of dynamic pricing that’s influenced by demand, location, and your app activity.

Is Dynamic Pricing Fair?

Dynamic pricing can be seen as innovative, but when based on personal data like browsing history, it treads into murky ethical waters:

• Transparency: Most users are unaware that their browsing behaviour is being used against them.

• Lack of Control: Users have little say in how their data is collected or utilised.

• Unfair Advantage: It disproportionately affects users who lack knowledge of how to counter these practices.

How to Avoid Overpaying

Here are practical steps to protect yourself from browser-history-based dynamic pricing:

1. Use Incognito Mode: Private browsing prevents sites from accessing your cookies and tracking your previous visits.

2. Clear Cookies and Cache: Regularly deleting cookies ensures websites can’t see your past activity.

3. Browse on Multiple Devices: Check prices on different devices and browsers to spot variations.

4. Use VPNs: A Virtual Private Network masks your location, helping you avoid location-based pricing strategies.

5. Leverage Price Tracking Tools: Extensions like Honey or CamelCamelCamel monitor price trends and alert you to drops.

Ethical Implications and Consumer Advocacy

While businesses argue that dynamic pricing helps them maximise revenue, it raises several questions:

• Should businesses be required to disclose their pricing algorithms?

• At what point does dynamic pricing become discriminatory?

• How can consumers push for fairer practices?

As awareness grows, regulators may need to step in to ensure dynamic pricing practices remain fair and transparent.

Conclusion

Dynamic pricing based on browser history is a double-edged sword—it offers businesses a powerful tool to optimise profits but often at the expense of consumer trust. By understanding how it works and taking steps to protect your online behaviour, you can level the playing field and make sure you’re getting the best deal possible.
