We have a large client that we've been doing some web development work for. The other day I was asked to do some basic SEO for them. The problem is that they don't want their site to be cashed, and are at the current moment using robot.txt to disallow all bots.
Is there a way to let the bots in, without being cashed by them to achieve some sort of placement ?
I know there are tags like the below I can use, but I have not been able to find any info on how thy effect bots :
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Cache-Control" content="no-cache">
<meta http-equiv="Expires" content="0">
