Hi @Nomad8324
The first element that should be considered about adding a place in Google Maps is the possibility to have the place verified. Due to the large amount of contributions, the verification is mostly based on the possibility to find information online about the place. Public directories, but also articles about the place are used as a base for the verification.
The second one is just a tip: keep it simple. A lot of people think that to have the edit approved it is necessary to add as much information as you can: phone number, website, opening time, and they also add a lot of photos. But if one of the various elements cannot be verified, the whole edit will be rejected. Normally when I add a place I only add the basic elements: Name, Category, Address. Sometimes I also add a photo of the storefront where the name of the place is visible. Normally [in my case] it is approved in a few hours. Once approved, I add one by one the opening hours, the phone number and the website.
Of course there is a “trust factor” in there: a Local Guide with a high score of accepted additions will be trusted more than a newcomer.
For more details about the approval process you can read: [Why is my edit status “Pending” or “Not Applied”?](Why is my edit status “Pending” or “Not Applied”?).
I also want to inform you that I am changing your Category to Google Maps tips & tricks where it fit better. I have also removed the “Accessibility” tag, that is not related to the content of your post, and added some additional tag. For more details about this please read What are Connect categories?
