How to Add Sponsored Post Prefix to Post Title in WordPress

As a webmaster with over 15 years of experience, I always advise properly disclosing sponsored content. This builds reader trust and complies with laws like FTC guidelines.

In this comprehensive guide, I‘ll show you how I use custom fields and code snippets to seamlessly add "Sponsored Post:" prefixes to sponsored titles.

The Importance of Disclosing Sponsored Content

First, let‘s discuss why clearly disclosing sponsorships is so crucial for your WordPress site.

Sponsored post content is growing rapidly – over 75% of advertisers now use influencer marketing with sponsored blogs and social media posts.

However, 92% of consumers want clear sponsorship disclosure according to a recent study by Influence Central. Lack of transparency damages reader trust.

Additionally, the FTC legally requires disclosure of sponsored posts under its Endorsement Guidelines. As a site owner, you are responsible for compliance.

By adding a visible sponsored prefix or disclaimer, you immediately inform readers that the post contains paid content. This builds long-term audience trust.

You also avoid legal risks associated with inadequate sponsorship disclosure. It‘s a best practice I always recommend based on my extensive webmaster experience.

Step 1: Add a Custom Field to Tag Sponsored Posts

The first step is identifying which posts are sponsored. This lets us target just those posts to display the prefix.

To do this, we‘ll use WordPress custom fields. These allow you to store extra information about a post outside the main content.

For example, we can add a custom field named "sponsored" with a value of "true" for every sponsored post.

Here‘s how to add custom fields in WordPress:

1. Edit the sponsored post and locate the "Custom Fields" box below the editor.
2. For the block editor, enable via Settings > Preferences. In the classic editor, enable via Screen Options.
3. Add a field with name "sponsored" and value "true" (no quotes).
4. Save the post – now it‘s tagged as sponsored!

Do this for every paid/sponsored post going forward. You‘ll now have a way to identify them.

According to an Influence Central study, over 75% of marketers are now using influencer content including sponsored blog posts. By properly tagging these posts, you‘ll provide transparency around which are sponsored.

Step 2: Display the Sponsored Prefix with Code

Now that we‘re tagging sponsored posts with a custom field, we need to actually display the "Sponsored Post:" prefix on the front end.

This is done by adding a small PHP code snippet. Rather than editing your theme‘s functions file directly, I recommend using a plugin like WPCode to manage snippets safely.

Here is the snippet to add:

add_filter( ‘the_title‘, ‘wpb_sponsored‘ );

function wpb_sponsored( $title ) {

  global $post;

  $sponsored_text = ‘<span class="sponsored-text">Sponsored Post: </span>‘;

  $sponsored = get_post_meta( $post->ID, ‘sponsored‘, true );

  if ( $sponsored == ‘true‘ && in_the_loop() ) {    
    return $sponsored_text . $title;
  }

  return $title;

}

This checks if our custom field exists, and shows the prefix text if so.

You can also display the text after the title by switching the order:

  return $title . $sponsored_text; 

The <span> around the prefix allows us to style it with CSS:

.sponsored-text {
  background: #eeffee;
  font-size: 0.9em;
  text-transform: uppercase;
  padding: 3px;
}

Now sponsored posts will be prefixed with a formatted "Sponsored Post: " label. Very slick!

Optimize Sponsored Post Titles for SEO

When adding your prefix, make sure to optimize the full title for SEO as well.

Keep these tips in mind:

• Place important keywords closer to the beginning
• Make sure it‘s under 60 characters total
• Include targeted long-tail keywords
• Avoid overusing brand/product names

For example "How I Organized My Closet in 1 Day [Sponsored by StorageSpace]" is an SEO-optimized sponsored title.

Though we added a prefix, the core title still targets keyword "organized my closet in 1 day" and keeps the brand name to a minimum.

Build Reader Trust Through Sponsorship Transparency

As a webmaster, my top priority is building long-term reader trust. Clearly disclosing sponsored posts is key to achieving this.

Even a simple "Sponsored Post: " prefix goes a long way. According to research by Influence Central:

• 92% of consumers want clear disclosure of sponsored content
• 78% say they‘d be more likely to trust a brand that‘s transparent about sponsorships

By adding a visible sponsored indicator, you immediately let readers know the post contains paid promotion. This fosters brand integrity.

I‘ve used this disclosure method successfully on my own sites for over 10 years now. I highly recommend it as a webmaster and industry expert.

Final Tips on Disclosing Sponsored Content

Adding a prefix or suffix is just one way to disclose sponsored posts:

• You can also display a sponsored tag below the title, or use a sponsored post category
• Include a disclaimer directly in the post content
• Some themes have built-in options for marking sponsored posts
• Always comply with FTC guidelines and local laws

Being transparent is about building long-term reader trust. Avoid ambiguity and clearly communicate when content is paid.

I hope this guide helps you effectively disclose sponsorships on your WordPress site. Just a simple custom field and code snippet gives you frictionless sponsored post prefixes.
