Are you looking for a newbie-friendly, fully automated, established website in a profitable, high-demand niche? Smart Home Vault (SHV) with a domain age of 2 years and 5 months has survived several Google updates. SHV receives on avg. 1000 monthly visits and has earned avg. of $120 monthly in the last six months. Products in the smart home devices vertical start at around $25 all the way up to $1000. The robot vacuum category has been filled with contents but being that the domain is broad and brandable, you can add as well add other categories like smoke detectors, smart plugs, smart switches, smart scales, window cleaner robots, etc.
I should mention that SHV is in a high competition niche. This means high demand, especially around November, December, and January. On the downside, keyword researching and backlinking are essential skills.
