A Comprehensive Guide to Dynamic Keyword Insertion (DKI) in WordPress using Javascript

In the dynamic landscape of digital marketing, the pursuit of relevance reigns supreme. The adage is simple: the more pertinent your advertisement is to a user's search query, the greater the likelihood of engagement. Dynamic Keyword Insertion (DKI) stands as a formidable technique enabling advertisers to tailor their ads and landing pages based on the user's search query. In this comprehensive guide, we will delve into the implementation of DKI in WordPress using the Oxygen Builder, rendering it accessible even to those just embarking on their digital marketing journey.

Unraveling the Dynamics of Dynamic Keyword Insertion (DKI)

Dynamic Keyword Insertion is a strategic tool within online advertising, with particular emphasis on pay-per-click (PPC) campaigns. It empowers advertisers to customize their ad content by dynamically inserting keywords that trigger the ad. This personalization amplifies the ad's relevance to the user's intent, leading to increased click-through rates and a higher probability of conversions.

Elevating the Power of Personalization

Imagine you, as a user, are in pursuit of the finest website builder. Your quest leads you to an ad bearing the message, "Leverage the Supreme Website Builder - Tailored to Your Needs." The element of intrigue here is the placeholder, denoted by "[Your Keyword]," which corresponds to your specific search query, such as "website builder." This level of personalized communication captures your attention, bolstering the likelihood of an immediate click.

Diving Deeper into DKI Functionality

Let us now explore the mechanics of DKI:

  • Ad Template: Advertisers craft a template with placeholders to accommodate the dynamic keyword. For instance, the template may feature "{Keyword:Default}" in the ad's headline.
  • Default Text: The "Default" text assumes a fallback role when the keyword exceeds character limitations or remains inaccessible.
  • Keyword Match: When a user's search query aligns with a specified keyword in the ad group, the ad platform seamlessly substitutes the placeholder with the corresponding keyword.

The primary merit of DKI lies in its ability to synchronize ad content with the user's search query, culminating in elevated click-through rates and the potential for superior campaign performance.

Integrating DKI into Landing Pages

With your ads now intricately personalized through DKI, it is essential to ensure a seamless transition from the ad to the landing page, preserving the level of personalization that initially captured the user's interest.

Leveraging WordPress for Landing Pages

The utilization of WordPress, augmented by free plugins, emerges as an astute approach for constructing dynamic landing pages devoid of custom PHP coding. While the Oxygen Builder offers a robust solution, it is prudent to acquaint oneself with alternative methods for executing Dynamic Keyword Insertion in WordPress. Whether you are an entry-level WordPress user or a seasoned veteran, these methods furnish a foundational understanding of personalization, setting the stage for the advanced techniques to be explored in tandem with the Oxygen Builder.

1. Manual Code Editing

For individuals well-versed in coding, manual incorporation of DKI variables into WordPress pages can be considered. This method grants complete control over the placement and customization of dynamic content. Nevertheless, it necessitates a comprehensive grasp of HTML, CSS, and PHP, rendering it potentially unsuitable for novices.

2. Dynamic Content Plugins

Within the realm of WordPress, a plethora of plugins is available to facilitate dynamic content insertion. These plugins are designed with user-friendliness in mind, obviating the need for coding expertise. Prominent examples encompass Dynamic Widgets, Content Aware Sidebars, and Custom Content Shortcode. While these plugins simplify the process, they may be encumbered by certain limitations concerning customization and advanced features.

3. Dynamic Content Shortcodes

Another avenue for implementing DKI in WordPress involves the creation of custom shortcodes. This methodology enables users to delineate dynamic content and subsequently incorporate it within posts and pages through the utilization of shortcodes. The operational framework is intuitive, with content generated dynamically in accordance with predefined parameters.

Implementing DKI in WordPress with JavaScript on Oxygen Builder

To initiate the DKI process, adhere to these steps:

Step 1: Crafting Ads with DKI

  • Develop an ad copy containing placeholders for dynamic keywords, such as "{Keyword:Default}" in the headline.
  • Deploy a "Default" text to account for scenarios where the keyword cannot be applied or exceeds character limitations.
  • When a user's search query correlates with a designated keyword within your ad group, the ad platform seamlessly substitutes the placeholder with the matching keyword.

Step 2: Leveraging Oxygen Builder in WordPress

  • Begin by installing and activating the Oxygen Builder plugin within your WordPress platform.
  • Proceed to create custom landing page templates, granting the freedom to design layouts and structures in accordance with your preferences.
  • Augment the appeal of your landing page URLs by introducing query parameters, such as "{Keyword}."
  • Oxygen Builder accommodates the insertion of custom JavaScript into your pages, lending an element of dynamism to the user experience.

JavaScript Code Implementation

Consider the following JavaScript code snippet for the dynamic replacement of H1 content based on the "dki" parameter in the URL:

javascriptCopy code

// Function to retrieve query parameters from the URL
function getQueryParameters() {
    var queryParams = {};
    var queryString =;
    var pairs = queryString.split('&');
    for (var i = 0; i < pairs.length; i++) {
        var pair = pairs[i].split('=');
        if pair.length === 2) {
            queryParams[pair[0]] = decodeURIComponent(pair[1]);
    return queryParams;

// Function to customize the H1 element based on the 'dki' query parameter
function customizeH1() {
    var queryParams = getQueryParameters();
    var h1Element = document.querySelector('h1'); // Assuming your H1 element is designated by the 'h1' tag
    if (queryParams.hasOwnProperty('dki')) {
        var dkiKeyword = queryParams['dki'];
        if (dkiKeyword === 'website-builder') {
            h1Element.textContent = "Unlock the Best Website Builder in the World for DKI";

// Postpone the page load until the DOM is prepared
document.addEventListener("DOMContentLoaded", function() {
    // Further customization logic can be added for other elements as required.

Step 3: Tailoring Your Landing Page

With the formidable capabilities of Oxygen Builder at your disposal, commence the process of customizing your landing page:

  • Leverage the visual design capabilities provided by Oxygen Builder to tailor your landing page to precise specifications. This encompasses the modification of layout, styling, and the integration of diverse page elements.
  • Oxygen Builder is attuned to the demands of dynamic content, permitting the introduction of dynamic elements contingent upon query parameters.

Testing and Optimization

Subsequent to the successful integration of DKI, it is incumbent upon you to meticulously monitor the performance of your landing pages and advertisements. This necessitates the deployment of sophisticated tools such as Google Analytics, in conjunction with A/B testing, to continually refine and optimize your campaigns.

In Conclusion

Dynamic Keyword Insertion stands as a potent instrument for augmenting the relevance of your advertisements and landing pages. When wielded effectively, it yields elevated click-through rates and heightened conversion potential. Through the amalgamation of WordPress and the Oxygen Builder, individuals, even those devoid of extensive coding proficiency, can fashion personalized user experiences that resonate with audiences.

Within the ever-evolving landscape of digital marketing, personalization stands as the keystone to triumph. Dynamic Keyword Insertion emerges as your passport to crafting advertisements and landing pages that converse directly with the needs of your audience. As you embark on this journey, anticipate your campaigns ascending to new heights.
