Site Feed:

Definitely enable the site feed. If your posts tend to be very short, you might enable full descriptions. But if you have long posts (which I recommend), do not enable the full feed, use the short feed. Here’s why:If you put the full post in your RSS feed, then the person reading the feed doesn’t have a reason to go back to your blog since they have already read the full post. No visitors to the blog means no clicks on your ads. AdSense has an “AdSense For Feeds” in beta testing, but it’s not open to all publishers yet, so at least for now you need to induce people to visit the blog.If they can only read part of the blog post, then if they want the whole story they will need to go to your blog. You can plan for this by making sure that your title and the first 255 characters (about the first 50 words) really pull in the reader’s attention. You need to use those first 50 words to make them just have to read the rest.Also, if your RSS feed appears on websites, you don’t want to give away the farm by showing the whole post. You’re letting websites use your feed so you can get clicks on the posts in that feed and get visitors to your site to build AdSense revenue.So set the “Descriptions” to Short, write long posts and make the title and the first 50 words count
