Personalization Series #2: URL Parameter Personalization

In our ongoing series on personalization techniques for boosting conversions, today we look at how content can be personalized using URL parameters.

This method works particularly well in combination with advertising channels and ad messaging. In this strategy, we use our Personalization Engine to tailor a customer's website or landing page so that, depending on the advertising channel a user previously visited or the search they previously performed, it delivers the most relevant information to them in real time.

What Is URL Parameter Insertion?

URL parameter insertion is an advanced personalization method within website conversion optimization. It uses URL variables — for example, from Google Ads campaigns — to dynamically display content depending on where the user is coming from or which parameters are passed along.

This creates a tailored user experience that increases relevance and improves conversion rates.

How Does the Personalization Work?

Let's take a Google Ads campaign with an ad and the following fictional link as an example:

www.bestcreditcardintheworld.com/hot-offer?utm_source=sea&utm_medium=paid&utm_campaign=freecard&utm_term=visacard

Process

A person sees a Google ad for their search term "no-fee credit card"

Clicking the link calls up the destination URL stored in the ad, including the attached parameters

The landing page reads these parameters

Based on the parameters, the Personalization Engine shows the user the corresponding content — or a fallback if no parameter is attached or the parameter is unrecognized

What Are the Possibilities for URL Parameter Personalization?

The possibilities here are extremely broad: for every advertising channel where you can shape the URL yourself, you can attach any parameters you like and then display correspondingly structured content on the landing page. Here are a few examples that have proven especially effective in practice:

Dynamic insertion of the search term: The website adapts the welcome text based on the user's search term. For example, it might simply say: "Welcome! If you're searching for [search term], you've come to the right place!"

Product display: On e-commerce websites, product images or descriptions are shown depending on the item the user searched for. If someone searches for "Visa credit card" or responds to a campaign for a Visa card, images or information about the Visa card are highlighted.

Use of campaign visuals: Images used in advertising campaigns are also displayed on the landing page to create continuity and recognition.

Demographic differentiation: Website content can be adapted based on the user's demographic information, such as age or gender, enabling different messaging for different target groups.

Categorization of campaign content: The website can identify different advertising campaign categories and display corresponding content. For example, if messaging is differentiated between informational and emotional appeals, this type of messaging can be carried through to the landing page as well.

Differentiation by USP: Similar to categorizing by campaign content, personalization can be based on the specific unique selling proposition (USP) the user is most interested in. If, for instance, a particular product benefit is especially important to a user and they respond to an ad highlighting it, that same benefit is prominently featured on the landing page through personalization.

Success Story "Automotive" Results:

In our case study of an automotive client, we used the keywords from the Google campaign to personalize the landing page — combining the campaign visuals used with the campaigns deployed in Google Ads — with the following result:

26% conversion uplift from personalization compared to the standard landing page

Conclusion

Personalizing based on search results or the campaign visuals a user responds to is an efficient way to demonstrably boost performance and improve the customer experience.

Browser vendors are making efforts to restrict URL parameters (for example, Apple's Safari blocks URL parameters in private browsing mode), so it remains to be seen which personalization techniques will remain viable in the years ahead.

For this method, it's essential to analyze the client's existing structure — for example, for the campaigns to be personalized — and develop tailored solutions to maintain the corresponding level of efficiency.
