Hello,
These elements are very useful for our support in order to know your build number.
Otherwise, the commentaries are not read by robots and if you really want to optimize your page content, you can use specific Joomla add-ons to do so, like JCH Optimize for example.

By the way, do not send me private message, use the "contact us" form instead.
