How do I manually change the SEF, HTML Title, meta and Robots tag?

Easy as you please.

Log into the SerrBizSEF control panel.
Click the SEF icon in the top navigation
In the NON SEF column, click the LINK you want to modify.

A new panel will open.

From there, you can change the SEF, HTML Title, meta and Robots tags as you like.

See diagram below.

Note: At this time (10/11/07) you can only use / or .html or .htm.  We are working on adjustment to allow any extension you like.
