Did you ever wonder how some people are able to display ads on their rss feed? Sure, you can modify core files to do it, but that’s not a good idea at all. Here’s a clean way to insert ads (or anything) on your rss feed, without having to hack any core file.
In order to achieve this recipe, paste the code below to the functions.php file from your theme. If your theme doesn't have a functions.php file, create it.
<?php
function insertAds($content) {
$content = $content.'<hr /><a href="http://www.wprecipes.com">Have you visited WpRecipes today?</a><hr />';
return $content;
}
add_filter('the_excerpt_rss', 'insertAds');
add_filter('the_content_rss', 'insertAds');
?>
Here, we first create a function called insertAds(), which concatenate a code containing our advertisment to the $content variable, which contains the content of the post.
Then, we use the add_filter() function to overwrite the the_content_rss() function with our insertAds() function. We use another filter to overwrite the_excerpt_rss() function as well.
That's all, your rss feeds now displays your ads!
Credits goes to k-ny for this awesome recipe!

Héhé, merci pour le lien
Du coup je m’abonne !
I don’t think this works for Atom feeds however. I’ve tried to modify feeds by hooking the_content_rss and not had my functions executed. If you look in feed-atom.php, it calls the_content, not the_content_rss. feed-rss.php appears to correctly use the_content_rss.
@Julien: Merci à toi pour cet excellent article!
@King Rat: I didn’t tested it with Atom feeds, only rss. I’ll take a look
Has anyone tried this? Is there any working demo?
Thanks in advance!
Thank you for the great recipe! Tried to look for this a long time.
I tried this, and actually it works.
But I get this error message:
Warning: Cannot modify header information – headers already sent by (output started at /home/edwinp/public_html/wp-content/themes/flashnews/functions.php:548) in /home/edwinp/public_html/wp-includes/feed-rss2.php on line 8
Any suggestion how to fix this?
I think feedburner can easily put your adsense ads in your feeds…. this is perfect to those who do not use feedburner
@Edo: Weird…I didn’t had the problem so I can’t help you, sadly
@Popular Technology: Yes, feedburner can put adsense in your feed, but this recipe should help if you want to include other ads as such as affiliate marketing ads, for exemple.
@Popular Technology
You can also use this trick to insert a copyright.
@Edo
It is an encoding problem. We must save the functions.php in utf-8 without BOM (sometimes done to save through the theme editor repair the problem)
Ps: Sorry for the automatic translation
Is this better than using a plugin for putting a text of line in the rss-feed?
@Kaj Rietberg: It is basically the same effect. It mostly depends if YOU prefer using a plugin, or play with code
Thanks Man
but still ads is not showing up !!
What is the plugin that do similar effect that would you recommend? I tried to save the function.php in utf-8, still doesn’t work
not working for me…
input this to my functions.php
function insertAds($content) {
$content = $content.’ads link’;
return $content;
}
add_filter(‘the_excerpt_rss’, ‘insertAds’);
add_filter(‘the_content_rss’, ‘insertAds’);
@muhammad hakim: Do it works for you if you use the sample code I have provided?
@muhammad hakim
Seems that the filter don’t work on WP 2.5. There’s a bug in WordPress core. To avoid the problem, try something like this:
function gopostrss($content) {
if(is_feed()){
$content = ‘text before content’.$content.’ and after the content !’;
}
return $content;
}
add_filter(‘the_content’, ‘gopostrss’);
Ps: I added this hack on the original source
I tried the code in the post, and it didn’t work. Then I tried julien’s code, and it worked! Thank you julien!
@Betty: Yes, seems that there’s a bug in WP 2.5 and the code didn’t works. Glad Julien’s help was useful to you!

(Nice gravatar, btw
@Jean-Baptiste Jung:
Perhaps not only a bug in WP 2.5, because I’m using WP 2.7 now.
You gravatar is very cute, too.
BTW: I wrote a post about it and sent a trackback to here, but the trackback is not appearing…
I think this is a great script. It is work for WP 2.7 ?
@Busby SEO: Yes, it does
Hi Jean,
Thanks for your confirm.
Hi,
that looks slick. Can I add picture rather then a text link as an add.
Any hints how the code has to look like ?
I use wp125-ad-plugin-wordpress to dispaly my ads in the blog and WP 2.7
Thank you in advance
icewalker
@icewalker: Sure you can, just use the <img tag.
thanks for this tip, how do I get ads to show up in my comments RSS feed?
thanks
can’t get it to work at http://www.marcoraaphorst.nl/feed/ maybe because of Feedburner?
thanks to share this info. i never think about this before ( we can add ads on RSS feed)
great, i’ll use your trick to add my adsense ads on my RSS.
How can we add the ad to the end of the RSS, cause right now it is displaying on each content. And it is repeation.
@julien
I don’t know what’s wrong with my feed.
Since I add the code, the wordpress doesn’t work totally.
Is the code compatible with wordpress v2.9.2?
How can i add custom meta. i am trying to add images but it seem they dont work.
