Should I Insert Special Tittle For Paid Post?

I wonder how others people writing their sponsor post? .. I'm used to be very forgetful and always forget to separate the paid post and own post..Sometimes I can't even remember which is own post and which is paid post..May be I have write too many already?

Should I separate those post with specific on the title? so that I could easily know which is sponsored? Just just leave it like now? Well, wait and see what happen next..I haven't find my way to settle this yet..hmm..maybe I should write less paid post then will be great solution..But then I have no $$ to spend anymore...
