Keywords given to us for HOTH Local aren't as important as keywords for our regular HOTH service, because we don't use them as anchors. We use them as tags, or keywords in directories that allow them. So, don't stress too much about them.
Nevertheless, we do recommend that you choose keywords that trigger Google Places/Local. Search your keywords on Google, and see for yourself if they bring up maps or a local "pack" or carousel. We also suggest using keywords with citynames in them. You really want to drive the point home for Google regarding where you are located. Of course, keyword search volume is important too, and you can use SEMrush or Google Adwords for that data.
