1. Log into your Blogger account. 2. Click the "Layout" link under your blog name on the Dashboard. If you don't have such a link, go to your Templates page for your blog and click the "AdSense" tab. 3. If you have clicked the "Layout" link earlier, you will now be given a choice of where to place your advertisments. For example, if you want to put your ad in the side column click the "Add a Page Element" link in that column. If you want it at the bottom of the page, click the similarly named link at the bottom. A new window will open, allowing you to choose the type of page element you want to add. Click the checkbox beside "AdSense". You will be brought to yet another page when you do that. Look for the "Sign in" link and click it. Enter your AdSense login and password to log into your AdSense account. Note: Those who had to click an "AdSense" tab in the first step will not have the choice of choosing where to place your advertisements. If that's the case for you, just skip to the next step. 4. Once you have signed in, you will be brought to a screen that allows you to choose the size and colour scheme of your advertisements. A preview window underneath your selection shows you what your advert will look like. 5. When you're done, click the "Save changes" button. That's it. When you next check out your blog, you should be able to see your advertisements.
