A backlink is a link from another website that points to your website. If a local news site writes an article and links to your business page, that link is a backlink for you. They are sometimes called inbound links or incoming links.
Backlinks matter because Google uses them as a signal of trust and authority. The logic goes back to Google's founding idea: if lots of reputable sites link to a page, that page is probably worth something. Each quality backlink acts like a vote of confidence from one site to another.
For a Maine contractor, a backlink from the local chamber of commerce or a respected trade association carries real weight — it tells Google that established, relevant sources vouch for this business.
