there is no such thing as a right or wrong way to earn money online at all .. google adsense is just one way to earn .. there's e-commerce and many other ways too ..

It depends on the way you want to earn.
Make a site with good and unique content then you adsense to monetize your site.

It is fi you are good at writing and designing web sites. eBay and coding also works well. Check this out for more info:

I think it's the right way if you have the patience for it. It pays off on the long term.

Exactly it pays off on the long run, you can get the most out of AdSense by:
* Increase traffic, creating more keyword-focused pages.
* Increase click-through rate, use simple design with the AdSense ads displayed prominently.
* Increase the value of clicks by creating pages optimized for them, within your site's theme.

If you are able to generate traffic to your site, it can be an effective (and very popular) way to make money online. However, to do this, your site has to have relevant, updated content that will no only bring someone there once, but back again. Focus on creating a quality site, and then back it up by optimizing your search engine rankings, and adsense should become very handy.

I believe you should not just depend on one avenue, be it google adsense or some other ads provider. There's no harm using multiple ads provider simultaneously.

I think Adsense is best way for webmasters.

you can also try adbrite....no need to wait for activation ...just create account and get ads...
