What is AJAX ?

 

Meaning of AJAX

AJAX stands for Asynchronous JavaScript and XML. It’s a technique used to create dynamic web pages that update content without requiring a full page reload. An AJAX-enabled website allows you to interact with the webpage content without waiting for the page to reload completely.

Relevance of AJAX in SEO

 Well, search engines use bots to crawl and index websites. These bots typically have a harder time understanding AJAX content because it’s loaded dynamically and may not be visible in the page source code. Because of this, it could be challenging for search engines to correctly index the content of an AJAX-enabled website.

However, there are ways to make AJAX content more accessible to search engines. One way is to use a technique called Progressive Enhancement, which involves providing alternate content for search engines and users who don’t have JavaScript enabled. Another way is to use the History API to update the URL and allow search engines to index the new page.

Here are some key takeaways to remember about AJAX in SEO :

1. AJAX can make it harder for search engines to understand the content on a website.

2. Progressive Enhancement and the History API are two ways to make AJAX content more accessible to search engines.

3. Good examples of AJAX in SEO include websites that use AJAX to improve user experience without sacrificing search engine accessibility.

4. Bad examples of AJAX in SEO include websites that rely heavily on AJAX for content that is not accessible to search engines.

Google guidelines for AJAX in SEO :

Google recommends using Progressive Enhancement to make AJAX content accessible to search engines. They also recommend using the History API to update the URL and allow search engines to index the new page. Google has provided some guidelines for using AJAX in SEO.  Following are the guidelines :

1. Offer alternative material that is accessible to both non-JavaScript users and search engines. Because AJAX content can be challenging for search engines to crawl and index, alternative content should be made available.

2. Progressive Enhancement can accomplish this by loading the material dynamically with JavaScript while also providing a different version of the content for non-JavaScript users.

3. Use the History API: When using AJAX to dynamically load content, it’s important to use the History API to update the URL and allow search engines to crawl and index the new page. This aids in the comprehension of the page’s content by search engines and raises the page’s position in the SERPs.

4. Avoid using the hashbang (#!) URL structure: The hashbang (#!) URL structure was once recommended by Google as a way to make AJAX content crawlable. However, this method is now considered outdated, and Google recommends using the History API instead.

5. Make sure all material is accessible: If AJAX is being used to load significant information, such as text, photos, or videos, it’s crucial to make sure that this content is accessible to all users, including those who are disabled. This can be achieved by using semantic markup, such as alt text for images, and providing captions for videos.

These recommendations will help you make sure that your AJAX content is both user- and search engine-friendly, which will raise the ranking of your website in the SERPs.

Steps to use AJAX :

You must create JavaScript code that requests the server and receives data without requiring a complete page reload in order to use AJAX on your website.

The fundamental steps for utilising AJAX are as follows:

1. Make an XMLHttpRequest object so that you may use JavaScript to transmit and receive data to and from the server.

2. Establish a connection with the server: To define the request’s type (GET or POST), the server-side script’s URL, and whether it should be asynchronous, use the open() function.

3. Send request to the server: Deliver the request to the server using the send() method.

4. Process the server response: To determine whether the server answer is ready, use the onreadystatechange event handler. The response data may then be retrieved using the responseText or responseXML attribute.

5. Update the page content: JavaScript can be used to update the page content dynamically after data has been retrieved from the server without requiring a complete page reload.

Here is an example of using AJAX to update the page’s content following the retrieval of data from the server.:

Using the open() and send() methods, the XMLHttpRequest object is formed in this example, and a request is then delivered to the server. The onreadystatechange event handler fires when the server response is prepared, and the responseText property is used to access the response contents. The content of an HTML element is lastly updated with the obtained data using the innerHTML attribute.

You would typically employ a server-side scripting language such as PHP, Python, or Node to manage the AJAX requests and provide the data to the client-side JavaScript code .js
