AJAX Search for WordPress Websites: Live Search Results at Lightning Speed

Want to make your site even more user-friendly?

Then, you need to add AJAX search to it. It will help you quickly find the pages or materials you need and display them without page refresh. Search results with the AJAX are shown at lightning speed.

Let’s see how it works and how you can add such a system to a WordPress website.

What Is AJAX?

AJAX stands for Asynchronous JavaScript and XML. It is a set of web development techniques that allow web applications to update content asynchronously without reloading the entire page but only update the data that requires it, such as search or filter results, certain elements, and other interactions with the user.

AJAX works by allowing web applications to send and receive data from a server asynchronously. Behind the scenes, the server and the client exchange small amounts of data to update the necessary parts without reloading the entire page. It uses a combination of technologies, including JavaScript for making asynchronous requests and XML or JSON for data interchange. Even though XML is part of the “X” in “AJAX,” JSON has recently been more commonly used than XML.

Another way of handling requests is page reload, which is usually more stable and easier to develop but not as good from a UX point of view. An easy way to describe what AJAX does is to say that it adds an extra layer between a standard GET request (which reloads the page) and more efficient, targeted data fetching (which doesn’t reload the page). AJAX allows you to tell the server exactly what data to retrieve and in which format (like JSON) to return it without reloading the entire page.

Pros and Cons of Using AJAX Search for WordPress Websites

Let’s discuss the pros and cons of using AJAX search and how it can improve your website’s user experience.

Pros

  1. AJAX technology improves user experience. AJAX search provides real-time search results as users type, reducing the wait time and improving the overall user experience. The dynamic nature of AJAX search makes the website feel more interactive and engaging, which can lead to higher user satisfaction and retention rates.
  2. Reduced server load. By loading search results dynamically, AJAX search can reduce the need for full-page reloads, leading to more efficient use of server resources. 
  3. Enhanced search capabilities and user engagement. AJAX search can offer autocomplete suggestions, helping users find what they’re looking for more quickly. It allows for the implementation of advanced search filters and sorting options, making it easier for users to refine their search results.
  4. SEO benefits. Improved user experience and reduced bounce rates can indirectly benefit SEO by signaling to search engines that the website is high-quality and engaging. Real-time search results and suggestions can keep users on the site longer, increasing the likelihood of conversions and improving session duration metrics.

Cons

  1. Complex implementation. Setting up an AJAX search can be complex and may require advanced knowledge of JavaScript and PHP. But you can use plugins to make this process easier. 
  2. Increased load times for initial search. The initial loading time for the AJAX script can be longer, potentially affecting the page load speed, especially on mobile devices or slower networks. That’s why proper caching must be implemented to ensure AJAX requests do not slow down the website.
  3. SEO limitations. Since AJAX content is dynamically loaded, search engines may have difficulty crawling and indexing search results, potentially impacting SEO. Without proper configuration, AJAX search may not update the URL, making it difficult for users to bookmark or share specific search results.
  4. Security risks. If not implemented securely, AJAX is susceptible to CSRF and XSS attacks. Additionally, some hosting providers, firewalls, or security plugins may block AJAX requests, requiring manual adjustments to settings to ensure proper functionality.

4 Interesting AJAX Use Cases

Let’s see how AJAX search looks on a website in practice. To do this, consider several resources with a search created using the JetSearch plugin or JetSmartFilters.

The first travel website is for the Vancouver Islands Traveling. If you start typing a query in the search, the system offers you options, and after selecting the one you need, it quickly opens the page.

The following example is the Myblue4you website for booking yachts, catamarans, and sea trips. The resource offers water transport in various countries for different numbers of people, distances, etc.

To select a suitable option, enter the country, place, and type of boat in the search bar, and the system will automatically suggest available options.

You may have seen the following example of AJAX search in our Knowledge Base. It helps quickly find all the necessary information. For ease of navigation in the search, one can select a category, e.g., plugins, widgets, and other sections. If you do not know what category the required material belongs to, just enter keywords in the search box, and you will see all the relevant suggestions.
