Changing Blog Title can hurt SEO?

Good day, I just found out that putting a keyword in title makes you rank higher in Seo but im planning to change all the title in my blog/website. Does it hurt my ranking? Currently my average position in all keyword in gwmt is 7 and im afraid that i will hurt my serp. So this is what im gonna do I will not delete any of my title i will just add a keyword on it because my blog is targeting a specific company name and the keyword that i will add is the company name. I got 25+ pages and im planning to add the keyword in every title. Here is the example of my title. (How to Earn and im gonna change it to this How to earn in +company name/keyword.)

Yes it will hurt at first but then recover

If you provide a more relevant title it can only improve rankings..

Don't be afraid to tweak things

Just be careful not to use the same keyword in every title
