I`ve a client who is "concerned that the multiple URL`s created by tags will work against us without any benefit by using them." He plans to delete all tags.
The only trouble I have seen on sites occurs when tags and category names are duplicated. I am concerned this guy will cause himself harm, rather than help the situation. He was hit by Penguin in both 2012 and 2013, but refuses to admit it.
What would you say and do? Would you pitch in and help him delete all that tags (he refuses to do a noindex nofollow) or push hard to get him to prove his supposition before acting on it?
