Good backlinks come from relevant, trusted websites with real value and traffic. Bad backlinks are spammy, irrelevant, or mass-generated just for SEO A city directory can work well and isn’t spammy if it provides real value, real businesses, and actual local traffic. Selling ad space with backlinks is normal as long as the site isn’t built only for link selling.
