I believe it is safe to click if you really intended to grow from clicking the ad you can do so.

When you register for Google Ads, you are sent a code to your home/business address for verification. If you are using a different US-based IP address then there will be a mismatch.
Which country are you based in?

Hi - I wonder if you actually need to be a Facebook business manager?

This is how Facebook describes it -

"If you're an advertiser on Facebook who shares access to multiple Pages and ad accounts with other people, we recommend that you transition to Business Manager."

So, is this what you need? Are your friends working for your business?

Or do you simply want to set up a page that relates to your website? If so, what you should have done, is just set up a personal account, then added a business page to it.

My understanding of Facebook is that you are only allowed one Facebook Account per Person. That Person then has a Personal Profile, and they can also create Pages & Groups. Pages can be for Businesses and you can invite other People to become Admins of those Pages. I have numerous Pages myself, as well as access to Clients Pages and never had to authorise an email, except for many many years ago when I first signed up with Facebook. You do not need a seperate email account per Page, as that is not how Facebook works. You can managed all Business related activties using your single account.

My Facebook Business Manager is tied to my personal account. I think it doesn't matter what email you use.

To create a Business Manager:
Go to business.facebook.com/overview.
Click Create Account.
Enter a name for your business, your name and work email address and click Next.
Enter your business details and click Submit.

The one that will be most SEO freindly will be determined by whichever of the Two people search for most and has the lowest QSR. This can vary from keyword to keyword. So "What is the time?" may get a better score than "What's the time?" in the one search, but then in another "Who is the president of the U.S.A?" may well get a worse SEO score than "Who's the president of the U.S.A?".
It's really justall down to which one people search for andd has the lowest competition.
Hope that helps

From my personal experience Google won't care about the (is) or (' s). Honestly, go with the "is" but Google will basically catch the " best place to have a vacation" and it will automatically create many variations of that keyword.

This is my opinion but don't use the words what, where etc. Include those words in your title and Google will do the rest
