An Idea I Got from the Magazines
I'm sure you've seen these in a magazine - the main point of the article (insofar as the magazine is concerned) is highlighted.
How You Can Take This Concept and Do It on Your Pages/Posts
It's easy! You don't use the meta boxes in your website's dashboard to do this! Satisfy both your human readers AND the search engines!
Since we are taking our targeted keyword and putting it in the title and in the first paragraph, why not let that paragraph be the topic sentence(s) of the article? I have been doing this for awhile and it appears to be working.
I'm going to doctor up one of my older pages. This works with posts too!
Note: Unlike magazines, which duplicate these blurbs out of the text and feature them as above, we don't repeat the text - in other words, the blurb (topic sentences) appear only one time in an online article. It doesn't really need to appear twice.
