Outside of the design of your blog (that’s a whole other post) perhaps the best way of creating that impression is though your post’s title.
Titles are so important on many fronts – including:
- Grabbing Attention in Search Engines – Head over to Google and type in virtually any word you can think of and you’ll often find millions of results. The interesting thing is that for most search results in Google (and other SE’s) there is very little for readers to go by in deciding which result to click on. There is a title, a short excerpt and a URL. The most highlighted of these is the title and I believe it is key in getting SE referral clicks.
- Getting RSS Readers Attention – in a very similar way titles have the ability to grab the attention of those following your blog via RSS in news aggregators. Even if your feeds are full post feeds rather than excerpts it’s likely that most news aggregator readers scan the titles of posts for things that interest them rather than reading full text. The same principle is true in other indexes and directories like Technorati, del.icio.us, digg etc
