Hi,
I hope you all are doing great. I have a very old problem with K2 and that's tags.
The tags as useful as they are can also become very cumbersome and in search engines they backfire.
Look at the picture below and see how many 404 hits I had on tags from k2 items.
What do you guys suggest I do to solve this?
This list is only a snapshot. the list goes on and on.

Hello Fotis,

Yes, the screenshot doesn't open as I uploaded it. it's size is reduced and quality is poor. I will find a way to reattach and show you the list.
The tags are not deleted. The tags still exists in many items. once you click on the tag on the item it will list all the items with that list.
However, some how the tags are being scrawled by search engines and lead to impertinent pages and lots and lots of 404 errors. For example on one tag which still exist on the website I have 2090 404 errors!!!
This will impact your website adversely on the search engine. This amount of 404 errors from k2 tag system on one of my websites is over a million. it's insane.
For a long time I had been trying to find a solution and I haven't been successful.

Here is a screenshot of the tag redirect errors.
