What Does Ajax Load More Posts Mean?

Step 1 — Add Load More Button HTML in theme file

Edit:

home.php, archive.php, or wherever your loop exists.

Add after your post loop:

<div id="ajax-posts"></div>
<button id="loadmore" data-page="1" style="margin:20px auto;display:block;padding:10px 20px;">Load More</button>

Make sure your loop looks like this:

<?php
$paged = get_query_var('paged') ? get_query_var('paged') : 1;
$args = array('post_type' => 'post', 'posts_per_page' => 4, 'paged' => $paged);
$query = new WP_Query($args);
if($query->have_posts()):
    while($query->have_posts()): $query->the_post(); ?>
        <div class="single-post-item">
            <h2><?php the_title(); ?></h2>
        </div>
<?php endwhile; endif; wp_reset_postdata(); ?>

Step 2 — Create Ajax Handler (functions.php)

Add this code to functions.php.

function wplp_ajax_load_more_posts() {
    $paged = $_POST['page'] + 1;

    $args = array(
        'post_type' => 'post',
        'posts_per_page' => 4,
        'paged' => $paged
    );

    $query = new WP_Query($args);

    if ($query->have_posts()):
        while ($query->have_posts()): $query->the_post(); ?>
        
        <div class="single-post-item">
            <h2><?php the_title(); ?></h2>
            <?php the_excerpt(); ?>
        </div>

    <?php endwhile;
    endif;
    wp_die();
}

add_action('wp_ajax_load_more_posts', 'wplp_ajax_load_more_posts');
add_action('wp_ajax_nopriv_load_more_posts', 'wplp_ajax_load_more_posts');

What this does:

• Receives the requested page number
• Loads the next posts
• Sends back HTML only (no layout duplication)

This is the heart of Ajax load more posts WordPress logic.

Step 3 — The JavaScript Fetch Request (Load More Button Script)

Paste this right before </body> in footer.php or enqueue it properly:

<script>
document.getElementById("loadmore").addEventListener("click", function () {
    let btn = this;
    let page = parseInt(btn.getAttribute("data-page"));
    
    let formData = new FormData();
    formData.append('action', 'load_more_posts');
    formData.append('page', page);

    fetch('<?php echo admin_url("admin-ajax.php"); ?>', {
        method: 'POST',
        body: formData
    })
    .then(res => res.text())
    .then(data => {
        if (data.trim() !== "") {
            document.getElementById("ajax-posts").innerHTML += data;
            btn.setAttribute("data-page", page + 1);
        } else {
            btn.innerText = "No More Posts";
            btn.disabled = true;
        }
    });
});
</script>

This script performs three actions:

• Sends page number to PHP
• Appends more posts below
• Disables button when no more posts

Step 4 — Style the Button (Optional)

#loadmore {
    background: #276ef1;
    color:#fff;
    border:none;
    border-radius:5px;
    cursor:pointer;
}
#loadmore:hover {
    background:#1b4bbf;
}

Does This Affect SEO?

Google scrolls through Ajax content surprisingly well now.

However, there are certain issues we face while scrolling. We share them here.
1 – The content added after click is still considered secondary
2 – For ad placement and engagement, Ajax load more posts WordPress is ideal
3 – You still keep traditional pagination active in the backend (SEO safe)

Tip: Do not replace pagination entirely. Hide pagination on front-end with CSS but keep the markup:

.pagination {display:none;}

How to Make It Infinite Scroll Later?

Simple — instead of button click, trigger JS when user reaches bottom:

window.onscroll = function() {
  if(window.innerHeight + window.scrollY >= document.body.scrollHeight - 200){
    document.getElementById("loadmore").click();
  }
};

You now have infinite scroll using ajax load more posts WordPress with minimal code.
