Small business website advice, Theresa edition

Heating oil and kerosene still heat 27.6% of homes in Theresa. Housing decides what kind of help people call for: repairs, heating service, roofing and yard work follow the kind of homes people live in. Service pages named the way customers search, plus the area you cover, works better than a single long list.
