(I'm using a page break, #4 on the list.)
1. Be yourself.
About.com says to "choose the appropriate tone." I guess I'm talking to people like me who are teacher hobby bloggers. Hobgers?
2. Use correct spelling and grammar.
But if your writing is as bad as my 14 year old students, it'll be hard to overcome.
3. Avoid cliche attention grabbers.
Give me a break. Most of the time, some study showed a slight correlation between two things, and bloggers and paid writers try to make it sound like there's a global paradigm shift.
I admit, sometimes I'm a sucker for a good list (see the next tip), but when 90% of the blog titles have some variation of the above formulas, the other 10% will start grabbing my attention.
Back to the go-to link, About.com says to pique curiosity and get attention while avoiding the bait-and-switch.
4. Use headlines and page breaks.Better yet, make a list. Yep, nailed that one right here. When people read blogs, chances are they'll look through all the headlines first, then decide whether to read it. (About.com calls it scannable.) If there's a list, I'll usually skip right over the introduction and head straight to the list.
Many blogs work similarly to Blogger in that, by default, every post is displayed in its entirety. This makes the blog itself non-scannable. To avoid this, you can use a page break. It makes it so the blog displays your post up to your page break, and the visitor has to click on the post to see the rest.
5. Use pictures.
There. You're a blogging expert.
