Welcome to the Q&A Forum

Hello! So I have a business that I run out of a single location for the last 3 years. I am unfortunately having to move here in the next few weeks My question is what do I need to do in order to have the best chance at SEO for the new location? When should I make the changes? Does it take a long time for me to stop showing up in the previous location? and is there something I need to do to remove those? Also, is there an app or a website where I can find and update all listings at once or at least a bulk of them? I know that there are some weird sites that have my business info in them that I did not put there. Obviously these would have the wrong address. Some do not have a contact info or a way for me to log into them. What would I do with these sites? Thank you!

I changed my URL from exampledetailing. com to exampleautodetailing. com. It is redirected with a 301. Also, it is on Squarespace AND I opted to add the www. So will the old backlinks of exampledetailing. com still help the new URL exampleautodetailing. com or do I need to try and update all the links? Also, future links, do I need to include the www. or just the root domain of exampleautodetailing. com or even the whole https://wwwexampleautodetailing. com? I believe the www is considered a sub domain and a new entity on Google, so I am not sure how that works. Thank you!
