Removing ads for your readers
If you are using ads like Google Adsense or BidVertiser to monetize your site, good for you I say. But why not reward your regular visitors by removing them, so they can enjoy your site without ads screaming “BUY ME” left and right. Believe it or not, you can actually MAKE more money with your ads by only displaying them to search engine visitors. Why? Because of a penalty Google has called smart pricing. Basically, you get punished by earning less for having a low click through rate (CTR). How do you increase your CTR? By making sure you show your ads to those who are most likely to click on them: the search engine visitors.
Now that we’ve established having ads (or at least Google Adsense ads) do you or your regular readers no good, why not remove them to make yourself some more money and your readers happy?
Paste the the code below into the functions.php file of your current theme. Remember to change YOURDOMAIN.com into well, your domain name.
$ref = $_SERVER['HTTP_REFERER'];
$SE = array('/search?', 'images.google.', 'web.info.com', 'search.', 'del.icio.us/search', 'soso.com', '/search/', '.yahoo.');
foreach ($SE as $source) {
if (strpos($ref,$source)!==false) {
setcookie("sevisitor", 1, time()+3600, "/", ".YOURDOMAIN.com");
$sevisitor=true;
}
}
function fromasearchengine(){
global $sevisitor;
if ($sevisitor==true || $_COOKIE["sevisitor"]==1) {
return true;
}
return false;
}
When you’re done, simply insert the code below wherever you want your ad to show.
<?php if (function_exists('fromasearchengine')) {
if (fromasearchengine()) { ?>
INSERT YOUR CODE HERE
<?php } } ?>
Sorry for not posting the code directly on my site. For some reason, putting code in my entries now break post.php, even when the code is in the code syntax and has been converted to HTML friendly entities. Anyone experience the same problem? It was a problem with my wording. Apparently WordPress is being whiny and I wrote certain words in a certain order which it did not like. Hence I had to change my wording. WTF D<

good idea – wrapping ads within cookies.

Thanks for posting this!! I hope some people will implement this… I hate sites where they constantly have ads… it slows down the processing and loading times like crazy.

Cecelia says:
I heard about this, but I just thought – “yeah, and how am I supposed to do that”… But I guess it doesn’t really matter now as I don’t have ads on my site anymore.. I will remember it for future reference though..
Cecelia´s last blog post..But where do I start?
Mimi says:
There are also plugins that do the same thing, but I prefer tweaking things myself; plugins tend to make my blog bloated :/
Lani says:
Thanks! It’s good to be back haha. This is a really good idea, there’s not much point in having those kinds of ads really otherwise cause normal visitors hardly ever click on them.
Mimi says:
Exactly, and apparently, they annoy more people than I had imagined. Definitely not good.
Kimm says:
I don’t mind some ad’s but when you have a personal site with lots it’s just way to much.
Once I get my work site up and running.. I might think about using this code.
Mimi says:
I can stand a few ads here and there, as long as they aren’t in my way and don’t clash with the designs. But of course, no ads is always better than ads
Angela says:
What a brilliant idea. I think I’m going to try that. Thanks for the info!!!!

Marsha says:
Ohh, I never knew you could do that. Thanks for sharing. Maybe one day I’ll actually implement Adsense again.

Did you see that Google have finally published the percentage we receive on adverts? But, it’s a fixed percentage, therefore no penalty for low click through rates.
