7yr aquarium content business generating $2,135/mo net profit from ads, affiliates & sponsorships

This is a 7-year-old freshwater aquarium media business with a 413-article library and ~9,600 backlinks (Domain Rating 48), generating ~$2,320/month net profit from display ads, sponsored posts, and affiliates. Since acquisition in 2022, the owner has built a monetized YouTube channel (~3,400 subscribers), a weekly email newsletter (2,114 subs), a ~10,000-follower Facebook page approved for monetization, and an early-stage SaaS tool (AquaTrack) with live paid billing. These newer channels are lightly monetized, giving a buyer growth paths beyond search. Display ads make up ~82% of revenue and depend on organic traffic, which has declined through Google core updates. Ideal for a digital publisher, aquarium/pet company, or hands-on operator comfortable with the content/SEO niche site model. Time commitment: 5–6 hours/week.
