Changing posts that target same keyword to target SIMILAR keywords

[Glinski]

Hello, I'm new to SEO and until the last year I was not aware that creating content that target same keywords would make Google choose only one to rank better.

Can I leave the best page (highest ranked one) as it is and change the rest that target the same keyword to target similar keywords ?

Just a simple example: I have two pages targeting "best supplements to muscle gain"

Leave the best one targeting that keyword and now I change the content of the other to target "best supplements for muscle size"

This is the smartest move or I'm missing something here and will make things worse ?

Ex: maybe some of tthose pages with same keyword arent ranking for the keyword I want but are ranking for another one that I dont know.

I'm really insecure about making changes and end up getting worse results..

Thank you (sorry for my bad english)

Glinski,

You should not be insecure about changes to your content. Remember content is designed for the target audience and if one page is geared towards muscle size and the next is muscle gain then the content of those pages should be written to reflect those ideas. This does not mean you need to be exact with the keywords. The meaning of the content needs to reflect what you want to rank for. So if both pages have similar content google will show the best content that is related to the users search intent. So you have an opportunity to rank for two separate keywords by changing the content on one page to more closely match the users intent "Muscle Size" or Muscle Gain" These are 2 very different ideas and can be easily differentiated with good content.
