So I installed this add-on....when do see the tag cloud?
Once someone lands on your page via any search engine. If you yourself are searching for your site make sure you aren't using https
Keyword tag i mean, sorry for that.
Or could you make a separate plugin for that, similar to XenMedio Keywords on every pages.
This add-on shows the results of keywords that brought users to your site (to be more precise, exactly to that page of your site) via search engines.
Example, you have a topic based on chess, random user searches chess on google and lands on your page, then the page shows the word 'chess' on "users found this page looking for" section. If it were clickable it'd not make sense coz if you click it you are directed to the same page anyway, and this is not meant for this add-on. XenMedio tag's does that since each video is tagged with certain keywords, this isn't exactly the same.
