Question about building amazon affiliate website

First, I want to say sorry if this is posted in the wrong place, I really didn't know anywhere else to post it. Is it better to host the website as you build the pages/content or should I build the website offline (With Mamp) and once it's completely finalize upload it? I figured it could be good to have live first so it looks more "aged" and slowly build up SEO, but I could also make a mistake and penalize it. On the other hand I though if I upload a finished website it could take more time after for google to rank/trust it? I was wondering what you guys think about it. Thanks!

I'd build the website and grow it . Looks more natural.

If you have good experience with wordpress then you can build the site live on the server. But if you are a beginner with wordpress then i would suggest to bulid it in mamp and uploading latter. However you must know that transferring a site from mamp to live server can sometimes be confusing and can break things, Good luck.

Just put to no index when u are building in on the server , then you will be find

Thanks for all the responses guys I think I'm just going to host it live.
