Is this good practice for SEO?

Just came to my mind this and i like to ask others about it. So i have website that have auto generated content on the pages.
The text it self is all the same but only some variables changing like (names, tags, pictures). So i was wondering is it good practice for SEO purposes, to make the text content change for some KEY keywords.
For example.
DaniWeb was founded in 2002 by Dani, who, at that time, was pursuing a computer science degree on Long Island, New York, and began gaining widespread attention throughout the search engine optimization industry in 2005.

On the second refresh to be something like this.
DaniWeb is founded in 2002 by Dani, which was pursuing a computer science degree on Long Island, New York and started to gain widespread attention throughout the SEO industry in 2005.

The above is just an example to get my point.

But i have on my website key keywords that users will search on google.
I plan to do this in the title & text also. But as i said only for some KEY keywords
Keyword: [UPDATED] -> [NEW], [LATEST], [RECENTLY]
Keyword: [LEAKED] -> [LEAKS], [HACKED], [HACK]
and so on...
