I am new to blogging and i have started a pc troubleshooting blog. Can i put ads on it now or after some time.
You can put ads on it at anytime. Blogger allow you to monetise your blog pretty much however you like.
You can place your ads right now. as you're having good content, you can make money online immediately..
I am using google adsense ads in blogs and blogger have built in pre-developed mechanism to place google ads between posts and on side bar.
No problem. You can put ad as soon as you like. I think that's why Blogger is free. They want you to advertise for them using Adsense
