Here's some google adsense tips to increase our earning
Tip #1: Don't put ads on empty pages.
1. 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.
2. 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.
3. 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.
4. It's better to flesh out the page before you start displaying ads on it.
Tip #2: Don't be afraid to ask questions
1. 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 email@example.com if you have additional technical questions or concerns. For general program or account questions, please email firstname.lastname@example.org.
-Their responses are always very polite, and they appreciate getting problem reports and suggestions.
Tip #3: Avoid non-English characters on English pages
1. This one is a bug, to be honest.
2. 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 .
Tip #4: Check your keyword density
1.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.
