If you like these tips, be sure to check out my AdSense book, Make Easy Money with Google: Using the AdSense Advertising Program, from Peachpit Press. See memwg.com for details. The book was mentioned in an article about AdSense in USA Today.

As explained in Why are ads displayed on this site?, most of the pages on this site display text ads from Google's AdWords program. To display these ads, a site must join Google's AdSense program. Joining is free, but not all sites are eligible to join. Once you're accepted, however, it's very simple to place the ads on your pages and to start generating revenue for your site. AdSense will serve ads that are generally very relevant to the content of a particular page. Here are some tips based on my experiences so far with the AdSense program.

Tip #1: 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.

Tip #2: 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.

Tip #3: 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 grave on 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.

Tip #4: 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: http://www.ranks.nl/tools/spider.html
This lets you fine-tune the page before exposing it to the AdSense crawler.
