Why is Adsense Showing a Dot Instead of an Ad?

For the past week now, I have encountered an error with my 160×600 Adsense ad unit. As you can see from the screen shot below, the top ad is missing. In its place is a dot. My guess is that the dot is suppose to be one of those new link unit image that Google has been testing. For whatever reason, Adsense can't find a relevant link unit image, so it displays a dot instead. I sent an email to Adsense support about the problem and they told me it was just an error and they don't think I will see the error again. That was two days ago and I still see the dot. It only happens once in a while, but it happens enough to annoy me. Is anyone else experiencing this problem?

Adsense Tip #457

Like many of you, I test my Adsense ads to improve the performance of the ads. In my latest test, I tested blended ads against ads that were slightly highlighted. The blended ads matched the content — white background with blue links. The highlighted ads had a light blue background. First, unlike most publishers, highlighted ads performed better for me in the content area. The click-through rate for the highlighted ads was three times higher than the blended ads. However, the ecpm was slightly higher for the blended ads. Though my guess is that the higher ecpm has more to do with Google serving better paying ads than because of the color of the ads.

Hello, I am an Annoying Ad

Update: Darren over at ProBlogger thought I might get in trouble for running the fake scrolling ad that I mentioned in the post below. After I got a heart attack and was brought back to life by a baby yanking on my hair, I emailed Adsense and YPN. Adsense guy didn't see a problem. However, YPN dude told me I need to pull the fake ad because it was blocking part of their ads. Strange I thought. I tested the fake ad on three different browsers and it didn't block any Adsense/YPN ads. So I sent a reply to YPN dude telling him that the fake ad did not block any YPN ads. I also sent the URL again in case I forgot to previously. YPN dude again sent me another email telling me to remove the fake ad because it was blocking their ads. I was pissed at this point because I concluded YPN dude didn't look at the URL I sent him. Then I had an idea, what if YPN dude didn't have his browser in full screen mode? Sure enough, when I resized my browser, the fake ad did indeed block both Adsense/YPN ads. As you can see, I no longer have the floating ad to show on this post. Thanks for the advice, Darren.

I bet you are having a little trouble reading this post because of the annoying ad in your face. The floating ad is an example of the post-it ads Jensense blogged about today. You scroll down, the ad moves down. You scroll up, the ad moves up.

The new ads by AdImpact look like post-it notes. Unlike real post-it notes, the ads are very annoying. Regardless of how much you scroll, the ads keep their same position. AdImpact offers the post-it ads for $20 a month. However, as Jennifer suspected, there are free scripts available. In case you have not noticed (ha-ha), I implemented a floating ad on this post so you can see it in action. I could have used a graphics instead of text to make them look more like real ads, but I figure you will be annoyed either way.

These floating ads are a good way to drive away your visitors. You might make a little extra money running them in the short term, but you'll pay for it in the long term. These are the types of ads I expect to see on the sites that game the search engines. You go there looking for something, but they don't have any real content — just keywords stuffed all over the page. All you can do is hit the back button or click on an ad. These sites do not expect repeat visitors. If you run floating ads, don't expect your visitors to return either.

AdSense API for the Big Boys

Google announced their AdSense API on their blog today. The API is in beta, but its free. So, what can you do with the Adsense API? Basically, the API allows visitors to your site to sign-up and manage Adsense accounts without ever leaving your web site. Why send your visitors to Google when you can keep them on your site? Great idea.

But there's more. If you act now, you also get a share of the revenue earned by publishers you sign up. In addition, you get a $100 bonus for each publisher who earns $100 within 180 days. I'm kidding about the "act now" part — couldn't resist.

So, what's the catch? Well, your site needs a minimum of 100,000 page views daily. Ouch! This will obviously weed out just above everyone except for the really big sites. It appears Google is targeting web hosts, blog hosts, Wiki hosts, forum hosts, and web publishers. Now the people behind a service like wordpress.com can make some money off of all those free accounts. I guess we can also expect more ISP's to offer free hosting if you sign up for Adsense on their site.
