Why Do I Need iSEO? Doesn’t Joomla Already Handle SEO?
Joomla's SEO capabilities are limited and slow. For example, Joomla doesn’t allow publishers to assign a title metatag to an article. Instead, article titles are used automatically as the title metatag even though the title of the article rarely contains keywords.
iSEO allows you to assign a title metatag for each article so you can optimize keywords and phrases.
