Are they the same?

Are search engines all setup the same way when it comes to indexing sites?

Search engines have different criteria for how they return search results, and most tend to change their algorithms on a regular basis. That means it is important to keep current on what each engine likes to see and make sure your site adheres to those changes.

So I can’t just setup my site and let it run? I could loose ranking because of this?

That is correct. Sites listed prominently one day may be at the bottom of the results the next. So it is important to pay attention to what the search engines want and give that to them.
