Hello everyone,
I'm currently facing a challenging situation and would greatly appreciate your expertise and guidance.
I own a website, maniflexa.com, primarily focused on the digital agency niche. About 3 months ago, I created a subfolder, maniflexa.com/emploi/, dedicated to job listings which is a completely different niche. The subfolder has around 120 posts and pages.
Unfortunately, since I created the subfolder, the rankings of my main site have been negatively impacted. I was previously ranking #1 for all local digital services keywords, but now, only 2 out of 16 keywords have maintained their positions. Other pages have dropped to positions 30 and beyond.
I'm considering a solution and would like your advice: I'm planning to purchase a new domain and migrate the content from maniflexa.com/emploi/ to newdomain.com. However, I want to ensure a smooth migration without affecting the main domain maniflexa.com rankings and losing backlinks from maniflexa.com/emploi/ pages.
Is moving the subfolder content to a new domain a viable solution? And how can I effectively redirect all pages from the subfolder to the new domain while preserving page ranks and backlinks?
I wish they did, but GSC doesn't offer a solution to migration content from subfolder to a new domain. 
Help a fellow Mozer. Thanks for giving a hand.
