Welcome to WordPress. This is your first post. Edit or delete it, then start blogging!
The search engines love posts. Why? Because it shows them there is new and relevent content being created on this site so there’s some action, plus it is ‘on topic’ for what you want the search engines to ‘know’ your site for therefore it must be valid.
Plus the power of blogging is that when you publish a new post it ‘pings’ the search engines (like internet sonar) telling them that there is new and relevent content to be found here, and they come and check you out. We’ve had content ‘indexed’ (found by, known of) by the search engines in under 6 minutes. Cool huh?
