I have some doubt's about google adsence, For adsence require any particular age for website ? Is this have any different terms and conditions for the blogs and websites?
Google can't see different between blog and website But website is more SEO friendly rather then blog. Well..It's not confirm but I read it from somewhere.
Google AdSense doesn't care how old your website. As long as your blog or website meets their terms and conditions, they will gladly use your website adspace. The same terms and conditions would apply to both blogs and websites. sheeba1 your blogs look like a prime candidate for Google AdSense. You have a lot of ad real estate along the right column of your website. You could plug a few adsense units there and get some extra revenue from your blogs. Earnings would depend on your amount of traffic and how much people are willing to pay for the keywords that your website focuses on. For some niches it can be quite profitable, for others it is not worth it. Sometimes you can make more by keeping your visitors focused on other things you offer such as affiliate programs or products for sale.
Age of the blog has got nothing to do with the Google Adsense program. If you want to earn well, you will need to have a lot of clicks on the Ads, which inturn depends on the number of visitors you get. So try improving the traffic to your site and i'm sure you could see 100$ in some time ( Not so quick ).
Adsense can be used on either blogs or websites, there is no distinction. Neither are better than the other, it's all about how you promote your site and the content you build on it.
No any terms and conditions. I have no website but with the help of blog I got adsense publisher id. If your blog is informative, you have chance that your adsense account will be activated by the google.
PR is not so much important factor major factor is relevancy of backlinks. But PR matter after relevancy..
Website is more fluid and you can own it. I use lots of free blogs and direct them as a pre-sale page to my owned website. There's nothing worse than not having total control of your web content especially when it becomes successful.
If you want to do link exchange you have to post your thread at link exchange section, my thread is not related to link exchange.
Page Rank doesn't matter google adsense. you need hug traffics. traffics will help to earn lot of money.
