If Joomla sees content as menu items and not pages then how does SEO work in Joomla. I am sure this has been written before but I haven't found it yet. Thanks. I am a new convert from Drupal.

Welcome....
How technical of an answer are you looking for?
On a really basic level Joomla does not see content as menu items, content can be
associated with a menu item. If you are wanting a full explanation let me
know.

If you don't mind. I am curious as to the hierarchy of Joomla and how search engines see it. Drupal forums point to Joomla difficulty with SEO.

People that say Joomla! has trouble with SEO are either misinformed or disingenuous.
Can it be better? sure... there is certainly room for improvement but this goes
with everything. Search Engine Optimization has to do with so many factors
that it is hard to pinpoint exactly where our friend on the Drupal forums see the
problem. There are a multitude of things such as keyword density, relevant
content, semantically correct html, meta tags, incoming/outgoing links, well structured
URLs, valid markup, etc... Now, I would assume since you are talking about
the menu structure and its correlation to the content system that you are mostly
referring to the URL system. The main problem that exists architecturally
with Joomla (in my opinion) is our dependency on the menu system as a framework.
It is an old problem that hasn't been addressed mainly because of the problems it
will cause with our extensive collection of third party extensions.
The menu system in Joomla is based on a database table with automatically incrementing
id numbers for each menu entry. As such, each menu item has a particular integer
value associated with it. This is what we refer to as Itemid and if you delve
into the code at all, you will see this is a variable that shows up pretty much
everywhere. Templates are assigned to menu Itemid numbers, modules are rendered
on certain Itemid numbers, etc... Because of this dependency every request
to the Joomla system should include an Itemid value. If one is not passed
to the system, it tries to figure out the appropriate Itemid and move forward...
or worst case, it defaults to a non-used Itemid for page rendering.
The content system in Joomla is actually just a very large component named com_content.
I am not familiar with Drupal so I can't give you a valid analogy of what a component
would be equivalent to in Drupal-speak. At any rate, the content component
acts independently of the menu structure and therefore pages can exist and be rendered
even if they are not "in the menu".
The association between the content system and menu system is where things get a
bit complicated. The menu system has some special cases for the content component,
which in reallity should not be surprising as the content component is the most
important component in a *content* management system.
The question I am thinking you are getting at, is more along the lines of.. what
is the relationship between the menu and URLs for Search Engine Friendly URLs.
Good question, and the answer is essentially one thing... Itemid. Every URL
passed to Joomla needs to have that Itemid with the notable exception of requesting
the base page (ie. www.domain.com/). All other parts of the URL are controlled
by the component that was called.
http://www.domain.com/index.php?option=com_content&task=view&id=1&Itemid=5
This URL when traslated to our native SEF URL system turns into
http://www.domain.com/content/view/1/5/
This all happens without querying the database for information about waht the title
of the article you are viewing is or the section or category it might reside in
for that matter. There are third party SEF extensions that allow for this
but it increases the server load a bit by making extra queries to provide that information.
The core development team has decided that until we can fix the architecture of
the system and provide a way to query once for the information, the core will use
the existing SEF URL system that keeps the server load as minimal as possible.
We have talked about the concept quite a bit and it will happen.... just a matter
of when, and what else comes along with it.
It should be noted that there are an enormous amount of sites with very good search
engine ranking using either our core SEF solution or even no SEF solution at all.
Hope that clears it up a bit for you

Thank you. I found that both educational and a good read. Trust me you would never get a response like that on Drupal forums. I look forward to working with Joomla.
