Google AdSense Tips

Google just released a Newbie Central for their AdSense program, those ads webmasters can include on their site to earn money for every click on the ad from a visitor (if you're using the program, part of the advertiser budget will go to you, and the other part to Google). I wanted to add some tips from my own experience:

1) Remove the Adsense Border. By default, the Adsense units are surrounded by a border with a text box at the top that says "Ads by Gooooogle". You goal is to work the Adsense units into your content as seamlessly as possible, so get rid of the borders. Now, Google won't allow you to delete the borders, but they do allow you to control the colors of nearly every element of an Adsense unit. Simply make the border the same color as the background of your website. This goes for the background color of the Adsense unit as well, change it to match the background color of your webpage.

2) Use Rectangular Box Sizes for your Adsense Units. Like most people, when I first started with Adsense, I primarily used the horizontal skyscraper, you know, the one that looks like a banner. The problem is people have developed an advertising sensory overload, they don't even see banner ads anymore, they visually tune them out. You need to make your Adsense unit blend in with your content, so use rectangular boxes. I get the best response with the 336X280 box size. Most languages are read from left to right, so try to place your rectangular Adsense unit in a table aligned to the right of your text.

3) It's all about the colors. Google gives you an incredible amount of leeway with the colors you can select for your Adsense units. Use this to your favor, in addition to changing the border and background color, change the link and URL color as well. Most people are accustomed to clickable links being blue, so make sure your Adsense links are blue, with one exception: if you use a different link color on your site, change the Adsense links to match that color. At the bottom of each Adsense unit there is the URL for website paying for that ad. You want to draw attention away from the URL and towards the clickable link, change the color of the link to match the body color of the ad, generally black.

4) Don't put ads on empty pages. When I reworked my site, I built a skeleton set of pages that had no content, just titles and some meta tags. I displayed ads on those pages, however. Although all you see are public service ads at first, the very act of displaying ads on a page causes the AdSense web crawler to quickly fetch that page for analysis. A page with good content will thus begin showing relevant paying ads fairly quickly.

If you don't have any content, then, Google will have to guess as what your page is about. It may guess wrong, and so the ads that it displays may not be relevant. You'll have to wait until Google re-crawls the site for the ads to correct themselves. Here is what Google had to say when I asked them about how often the AdSense crawler updates a site:

Thank you for taking the time to update your site. New ads will start appearing on your site the next time our crawler re-indexes your site. Unfortunately at this time, we are unable to control how often our crawlers index the content on your site. Crawling is done automatically by our bots. When new pages are added to your website or introduced to the AdSense program, our crawlers will usually get to them within 30 minutes. If you make changes to a page, however, it may take up to 2 or 3 weeks before the changes are reflected in our index. Until we are able to crawl your web pages, you may notice public service ads, for which you will not receive any earnings.

It's better to flesh out the page before you start displaying ads on it.

5) Don't be afraid to ask questions. If you're wondering about something, don't be afraid to ask Google. So far, they've always responded to my questions within a working day. There are two email addresses to use, depending on the type of question:

Please feel free to email us at adsense-tech@google.com if you have additional technical questions or concerns. For general program or account questions, please email adsense-support@google.com.

Their responses are always very polite, and they appreciate getting problem reports and suggestions.

6) Avoid non-English characters on English pages. This one is a bug, to be honest. My surname is French, and I prefer to write it out correctly with the accent graveon the first "e". Every page on my site would then include at least two accented letters, because my name shows up twice in the footer. On some pages my name shows up two or three more times.

Normally, this wouldn't be an issue. But on some pages the presence of the accented characters is enough to cause AdSense to display non-relevant ads in French. This happens whether the browser indicates a preference for French or not. When I reported this to Google, this is the answer they gave me:

Hello Eric, Thank you for bringing this issue to our attention. We are currently working as quickly as we can to address this problem. As soon as we have more information for you, we will email you again. We appreciate your patience. Sincerely, The Google Team

Until this is resolved, I've decided to strip out all accents except on the pages that are actually in French.

7) Check your keyword density. Although Google doesn't release exact details as to how they determine the ads to serve on a given page, they do tell us that it's the text content of the page that matters, not the meta tags. Before serving ads on a page, then, you might want to check its keyword density. A good, free tool for doing this is found here:

This lets you fine-tune the page before exposing it to the AdSense crawler.

8) Be aware of risks when you change ad layouts too much. I once had a system on the server to randomly differ between various AdSense layouts on the same page. Doing so I was hoping to add some good variety to keep the ads at least somewhat interesting and notable. Shortly after I stopped doing so and simply included a rather big static area for the AdSense to "do what it wants," the AdSense revenues for that site increased.

Now, I don't know if this was a coincidence of some sorts, as revenues often go down or up even when you don't do anything, but it might well have been that there was a connection between adding too much homemade randomization, and lowered revenues.

At another time, during the redesign of this blog, I switched from one ad format to another for the end-of-posts AdSense ad space. This, combined with perhaps other layout changes, suddenly cut the ad revenues in half for the blog. It took me some time to realize that I had some ad channels* set up for the specific old layout size, and by changing this I must have kicked out all those advertisers who were pushing their ads through the channel.

9) Sometimes you may get a sudden increase in traffic, hence ad clicks, but you can't locate the source of the traffic. I'm using Google Analytics to track my sites, though AdSense is also a good first indicator of traffic explosions... because it will show the combined page views of all your sites (provided you include AdSense on all of them), as opposed to Google Analytics, where you need to check site by site individually.

However, sometimes even with Google Analytics, you won't be able to locate the source of your traffic because there's no specific new popular referrer being shown (a referrer is the site linking to your site, provided people click on that link). In these cases, it may well be that your site has been discussed in a TV show or similar, as the show won't "link" to you (but audiences will be entering your domain manually into the browser when they like what the saw on TV). When you feel that there has been a traffic explosion sometimes you may get additional email feedback in regards to your site, and it makes sense for you to ask your visitor: where did you first find out about the site? Maybe the can let you know about the name of the TV show, or magazine, or other "offline" source responsible for the peak. (I sometimes sent pointers to the BBC Click show for instance, with partly enormous effect.)

10) Consider using AdSense even when the page doesn't get any traffic yet. Who knows, some day the traffic suddenly explodes, and you might not realize fast enough and thus miss out on the action (as sometimes, traffic goes as fast as it comes).

On the other hand, reversely I would suggest to never do a site just to make ad money with it. That kind of motivation may lead to spammy sites that don't help anyone really. (If a project is great, it's great even if it doesn't make any money.)

11) Making money with AdSense takes time. In my experience, it may take many months to years for a site to gain enough traffic to make OK money through AdSense... if ever. I have almost never experienced any site making quick and easy money with AdSense (though you may be getting quicker results than me of course, as it depends on so many variables!).

I think for any site getting a couple of thousands of visitors a day, you might want to start playing around with AdSense to see where it takes you (if you didn't already include AdSense anyway just to see what happens, and following up on tip #9). As you are paid in US-$, the actual benefit the ad revenue will bring depends on your local costs of living as well (you might even ponder moving or going on an extended holiday trip if your local costs of living are too high for your site revenues to cover).

Just follow these 11 simple guidelines and I assure you, your CTR will skyrocket. Keep adding more original, relevant content to your site, increase your targeted traffic, and watch your Adsense revenue explode.
