Quality Blog Posts are not enough for the Lead Generation. Why? And What to Do?

[SpaulSpace]

Hi!
I am working for a software development company: write some post about technologies for building webapps

https://webspaceteam.com/.

I think these posts are not bad:

https://webspaceteam.com/react-native/react-native-and-fastlane-for-ios

and so on.
My task is not just write posts but write such posts which will convert as many visitors to clients as possible. I discovered a problem: I cant attract a lot of leads just by writing posts… My boss thinks that I am working not so efficiently.
What do I do wrong?
