You may want to consider adding location-based keywords such as ""screen printing [your city name]"" or ""custom t-shirt printing [surrounding town name]"" to help target your specific area. As for more specific keywords like ""school shirts"" or ""church shirts,"" it could be useful if those are common types of orders you receive. You could also consider targeting specific events or holidays, like ""custom Halloween t-shirts"" or ""Christmas shirt printing."" To determine which keywords are most popular in your city, you could use a tool like Google Trends or a keyword research tool like Ahrefs or SEMrush to see search volume data for different keywords.
