JTagGen has a feature that will let you know if your keywords and description fields are too small or too large. This tab allows you to enter descriptive information about your site. For maximum effectiveness, be sure to complete all of the fields. An example of one property in this step is the Robot Text tag. When a search engine or crawler appears at your site, it will look for instructions as to what it can do.
Meta tags can accomplish two things.
First, they can communicate with an Application Server. Some application servers allow certain actions or events to occur depending on the embedded Meta data in HTML Documents. Enterprise Users using Controlled Vocabularies can use the Custom Subject tag. JTagGen lets you preview your results prior to updating. This allows you to go back and make changes prior to updating.
