I am uploading lots of content to my WP blog and I was wondering how people do their call-to-action? Do you put the same call-to-action at the end of ALL your articles? or just use the same call-to-action for 10-20 articles and then change it again? Basically *insert promotional sentence here* and then *link here*? Because writing a "unique" c-t-a in every article is a pain especially if you're uploading lots and lots of articles everyday.
