The homeowner is choosing a person, not a price
On a remodel or an addition, the buyer is about to let a stranger live in their house for months and hand over a very large check in stages. Long before they compare bids they are deciding who seems organized, communicative and unlikely to disappear. Almost everything persuasive on a general contracting website is a signal of those three things.
Completed project stories with scope and timeline, a clearly explained process, named licenses and insurance, and photos of you and your crew do more here than any headline.
