Make notes about these posts. What topics have they covered? How long are the posts, roughly? Do their posts tend to be high-level and strategic, or focused on specific tactics? Are the posts aimed at beginners or people with a lot of experience? All of this can help you hone your ideas appropriately.

Look at the categories the blog covers, if these are listed in their navigation. You might want to pay attention to categories that haven’t had many (or any) posts recently. These could be good targets for content that fills a “gap” on the blog. Keep in mind, though, that a lack of recent posts in a particular category could signal that the blog has changed direction.
