Here are a few grave mistakes you can intentionally make: you misrepresent your business information, create fake addresses, PO boxes; You abuse the positive reviews on and off-site like the Google My Business listing, Amazon reviews, Trustpilot, Android Store, etc.; you buy links to raise the authority of your pages, and even worse you use online forums, i.e., Fiverr.com, Freelancer.com, Upwork.com, Thehoth.com, etc., that sell cheap backlinks not fit to your website needs.
Here are some intentional but not grave mistakes: you build a page for each location (wishful thinking) even though you don't have the right amount of original content that meets the local needs; you are not optimizing for your local area first which would make sense given the fact that you are on a budget; you target with a separate page every keyword phrase you find in online tools.
