Adsense DIY – How to Use Competitive Ad Filter to Filter Out Irrelevant Ads!
Sometimes, your Adsense CTR can drop drastically on certain days and it may be because you have irrelevant ads on your blog or website.
As good as Google AdSense is at crawling your blog/website to serve the most relevant ads, there are times where you will simply get irrelevant ads.
For example, sometimes I have furniture advertisements out of no where on my tech blog that is totally irrelevant to my tech visitors.
If you see those kind of advertisements, it will drive down your CTR because the ads are not relevant to your blog readers. Plus, they even annoy the hell out of me because I don’t want to see ads that are not relevant, it makes my site look unprofessional.
There is a solution however, you can easily block those irrelevant ads from coming back so your users can see relevant ads thus driving your CTR back to normal.
To do this, simply go to Adsense Setup->Competitive Ad Filter, and enter the URLs (example.com). Those ads should stop appearing within 5 minutes or so.
Another important point here is that you want to actually type the domain name only without the www. For example, you want to type “example.com“, not “www.example.com” or “example.com/blahblahblah“. Doing this will block ALL ads from that domain, no matter what subdomains or pages its coming from.
In other times, your Adsense CTR can also drop drastically due to “ad spammers”. These people aren’t really “spammers” but I like to call them “ad spammers” as they will somehow buy a bulk of cheap graphic ads and keep “spamming” your blog/website with their ads only.
For example, you might see majority of your Adsense ads for one company. Depending on what that company is advertising, it can drive your CTR up or down.
If those ads drive your CTR down, you need to take them out as you are being “ad spammed”. Simply use the competitive ad filter to filter them out.
Plus, I rather see a bunch of different advertisers on my Adsense ads than a monopoly by a single advertiser, especially if those ads are irrelevant or simply driving your CTR down.
As a rule of thumb, if your CTR goes down, it probably means that your visitors are annoyed by your ads because it’s irrelevant or spammy. Make your visitors happy by showing more relevant ads, your CTR will probably go up and it will put a smile on your face.
On the other hand, if your Adsense ads are very relevant and not spammy, by means go ahead and do NOTHING. Like the old saying, “If it ain’t broke, don’t fix it.”
UPDATE: Before you try the method above, try section targeting your blog/website, especially if you have a lot of extra content.
