Question
I love reviewing products and want to make a review blog.
Lets say Toaster ovens gets a million search a month. Because people are searching for toaster ovens, cheap toaster ovens, gourmet toaster ovens, (brand name) toaster ovens, pink toaster ovens, Bagel toasters, etc.
Important to me: Also lets say the domain name 'Toaster Oven Reviews. com" was available.
So I think hmmm, i should make a site that reviews toaster ovens, because theres a BIG demand for a single niche.
But every one of my friends tells that I should review all kitchen appliances because Im limiting myself by only focusing on toaster ovens.
I just want a nice small business that I could quit my job and work full time job within 3-5 years. Also I have a tiny budget to start this.
So what makes sense here? thanks :)
Answer
First things first, I wouldn't rely on organic traffoc to a review blog for affiliate commission for your sole income, things come and go, so ideally you would need to build quite a few sites or a substantial business for it to be stable.
However, to your question, An incredibly niched down site may have its advantages, but the winner above all will be the review site with the most useful information that has all the comparisons and information that searchers want.
Just buying a focused domain and thinking type-in traffic from google will come, will not work any longer unless you can do it at scale. So if your passion really lies behind reviewing kitchen appliances (right!) I would build a site that is different than others and fills a gap in that area so it will be something that actually ranks and gets traffic... and in turn some amount of revenues.
