Creating titles for video tutorial

If you have multiple tutorials showing implementation or how to`s around a certain subject, we`ll just say: "pest control seo case study" would it be better to take all the different series of work / tutorials and break them into different posts or create one page that you continually update with all the different tutorials / analytics in that one page? Also if you`re marketing on different sources like YouTube, would it be better to make unique video titles for each video around let`s say, video 1: "seo implementation for pest control, video 2: "reporting for client" etc. or would it better to create a series for example: seo for pest control company part 1, seo for pest control company part 2. Thanks for the help guys.
