Work in progress
All Snap! Pages must have a title. It is mandatory. Depending on the type of page and/or the theme, the title is displayed in different places, however, it should always use an H1 tag1.
The title text field looks as follow:
Notice the little asterisk after the word Title:? This indicates that the title is required. Any field that is required will show such an asterisk. The color may vary depending on the theme you're using, but it generally is red.
The title can include any character, however, it cannot include HTML code. The < and > characters will be shown as such instead. Similarly, entering an entity such as ™ (™) won't work. Instead you want to enter the character itself. You may have more ease to enter special characters in the Body field2 (see under the Title) than in the Title itself, then copy and paste the character in the Title.
The title should be as descriptive as possible in about 63 characters. The threshold is in link with search engines that will cut your title at that length. It is important that all the important keywords for that page appear within those 63 characters.
Snap! automatically transforms your title into an SEO friendly URL (words that describe the page separated by dashes.) However, for some pages (i.e. /about, /contact, etc.) it may be preferable to enter the URL yourself. We will learn how to do that in a different page. However, if you write a journal, remember that the URL will be set to your title and this is a another place where your title appears.
One thing to remember is that this title will be sent to all your RSS feed subscribers. This means it needs to be compatible with their feed system. Website based feeds will generally work pretty well, although Feedburner is known to transform your special characters the wrong way. Desktop based feeds will often to properly interpret special characters.
To stay on the safe side, try to limit yourself to ISO-8859-1 (i.e. the ASCII characters and basic accentuated letters.) Other characters such as the long dash (—) won't make it.
Of course, this only applies to the pages that are sent to any one of your RSS feeds. For instance, Primary and Secondary pages are not being broadcast.
There are other places where the title will appear. For instance, when writing a Journal entry, the title and a teaser of your new journal entry appear on your front page. When creating an FAQ page, the title will show as the question (and the body is the answer.)
As an administrator, you also can get to lists of your posts (i.e. the Pages link in the toolbar Content tab.)
In most cases, when those titles appear anywhere on your website, they will show up just fine, whatever the characters used.
