This is a form based interface for managing content on this page. Not every page type has a composer template.

• Page Name - Used in navigations and your site map, this is the default name for the page.
• Description - This short description is used for your meta description field and the page list navigation.
• URL Slug - This is the vanity URL which this page will show up under. You can set additional ones up from the location page settings. 
• Page Template - This controls the layout of the page, change it to get different block areas.
• Page Location - Your whole site is a tree, this lets you choose where this page lives within the tree.

Note: Your CMS may also include additional fields depending on the page type selected.

The SEO Tab in settings brings important page specific SEO attributes together into one place for quick editing. You should also check out Bulk SEO in the dashboard for changing these values across many pages at once.

• URL Slug - This is the human readable vanity URL for this page. Instead of yoursite.com/index.php?cID=1341, the URL Slug lets you have yoursite.com/about_us.
• Meta Title - This field what is displayed along with your site name in the top of any browser, and is the linked title from google or other search engines.
• Meta Description - Search engines typically display this under the linked title for your page. 
• Meta Keywords - Some search engines search this to detemine what the page is about. Put a comma seperated list of words here that don't repeat too much. 
• Header Extra Content - Anything else you need to add to the HEAD section of your page can go here. For example, google webmaster tools have a special meta tag you can add to your home page to validate ownership, if you cut and paste the whole tag here it should show up in source.
• Exclude from Sitemap.xml - If you don't want this page to be crawled you can remove it from your sitemap.xml so that it isnt sent to be indexed.

Some of these settings may be editable from Location or Attributes as well, the SEO Tab just gives you a single place to goto for all page level SEO settings.

This settings tab lets you control where the current page lives in your web site. You can change the location of a page within the hierarchy of your site either when you create the page or after it has been created.

• Choose Location - Just like your computer's folder system, concrete5 manages your site with a tree where every page lives below another page (except for home which is the root of your tree). Clicking Choose Location lets you change the parent page of this current page we're editing.
• URLs to this Page - concrete5 will 301 redirect traffic that comes to different URLs to a single correct (canonical) URL. This is good for search engines which do not like the same content appearing at two different URLs. 
• Add URL - if you do want an alternative URL to point to this page, add it here and visitors to these URLs will be automatically redirected to the canonical. This is a great tool for popular pages or seasonal promotions that might be buried in the site but need a short URL for marketing purposes.

The settings > Attributes tab lets you change Custom Attributes that are tied to this page. In concrete5, Custom Attributes are variables that can be associated with pages, users, files, and if you're using the eCommerce add-on, products. They provide a great way of storing strongly typed data you can search and use for application development later.

• The left column displays all available attributes for this page type. You can limit the list by typing in the search box, and attributes that have been selected are highlighted blue.
• The right column displays the values for these attributes. Some common attribute types include:
• Name - The name of this page is displayed in various navigations in your site.
• Created Time - This is NOT a publish embargo date, but rather just the time and date to associate with this page in general. It's used for ordering & display in the blog.
• Author - This is NOT a permission of who can edit, but rather just a concrete5 user name to associate with the page (again used in the blog detail page type)
• Description - This short paragraph is displayed by the Page List block, and is typically included as meta description unless you add a specific one as an override.
• Exclude From Nav - if on, this hides this page from the Auto-Nav block
• Exclude From Page List - if on, hides this page from the Page List block
• Exclude from Search Index - if on, this page's content will not be included in search results.
