Two sites targeting same keywords (but with different owners)

[CayenneRed89]

Hi Guys

So we manage a client website doing their seo and ppc

The site has become a success so the client has now asked if we would like to create our own site and become an affiliate of theirs

The idea is target the same set of keywords etc.

My question is - in the world of google is this ok?  I know about google penalising same business owners for having two websites targeting the same keyword....

But in this case - the websites are owned by different owners, different hosting, different domain ownership, different analytics code, different code development, different about us

Everything is different but I am just a little paranoid that google knows we SEO the clients website

Does anyone have any advice?

Thanks
