For example I have the following link:
http://broodds.com/index.php/en/component/bet/?view=oddsdetails&bet_id=4e9dc53b96df3&odds=q1
I don't want to give access to the Google bot if the view is oddsdetails, is it possible to disable that. I'm using Joomla framework, so already there is a robots.txt, I want to extend that if it's possible.
In your template within the index.php <head></head> of your template you could use this:
$view = JRequest::getString('view');
if ($view == 'oddsdetail') { echo '<meta name="robots" content="NONE" />'; }
additionally, if you want to allow the robot to continue looking beyond this page, then what's best is to use:
$view = JRequest::getString('view');
if ($view == 'oddsdetail') { echo '<meta name="robots" content="NOINDEX" />'; }
This means Google won't index this page, but it will continue to go to any subsidiary links. NONE just tells Google to completely ignore this page.
You may want to consider using parameter handling in google webmaster tools which is for these types of urls.
