Quote from @Ronald Rohde:
"parking near me"
thats what people search for
+1 for putting things in the name that people are google searching for. You aren't trying (at this point) to create some nationwide brand, so being found on google, and when found knowing instantly exactly what you do, is top priority.
Not to "do your homework for you," but this is fun, let's take the GPT suggestions above from @Kristi Kandel
VersaStorage: Vehicle Parking and Self-Storage
Long-term vehicle parking is what you do, that not everyone does, so it comes first, when markets find equilibrium you will find higher profit margins on that, for that reason, so that's the priority. That way if google truncates, it becomes "VersaStorage Long Term Veh..."
And then for my main picture, the first thing people see, I'm making sure a boat is prominent, a semi or RV (whichever is a bigger market in my area), and a traditional self-storage space.
And then you are going to look at the marketing copy of your competitors. If you see a bunch of them offering something similar, like say a discount for a 12 month storage contract, or multi-vehicle discounts, then there's a really good reason they are all doing it (likely from lessons they had to learn the hard/slow/long way), so you are going to copy those ideas first and foremost. We aren't Jeff Bezos or Steve Jobs here, it's a storage facility: Impersonate, then iterate, then innovate.
Good luck! I smell a refi in your pipeline a year or so from now, remember this isn't a home loan, so "two years of tax returns showing a profit" is NOT a hard/fast rule at all to get the best terms.
