I found this "niche" on accident one evening. It's quite hilarious. There's a site that ranks so-so for the keywords. Its a CF23 domain with 170 referring IPs. 3rd party stats show that it gets at least 110,000 to 140,000 visitors/month. I've tested these stats against sites I own and I think they're pretty accurate. The site is also an Alexa 400,000 site, which backs these stats. This site has to be monetized with CPM ads. I'm estimating a $2 target CPM. If the stats are correct, that'll be $220/month on the low end and $280/month on the high end. Can I get an extra 10,000 views/month to reach $300/month? I think I can. The target site has at most 150 words on the page. The on-page SEO is OK (keyword in title and H1) but its quite thin in content. It has 16,000 indexed pages. Basically, a close example would be a site about "Can you smoke $Noun?". Examples would be: "Can you smoke cinnamon?", "Can you smoke plastic wrap?", and "Can you smoke water?". I'm not kidding. The ROI on this project is OK -- not the best nor the worse. The hilarity of this project is what sells it. Plus, it's pretty strait forward. Here's the plan: I scrape a list of $Nouns and figure out how many $Nouns there is. I then calculate how unique the spintext has to be. I'm guessing that it'll be larger than 16,000 as the target site is quite old. I buy an expired domain. I found one already. It's CF29 with 364 referring domains. It's still indexed in Google. I then make the site. The site will rank because it has more words, better on-page SEO, and more links. I'm gonna go with AdSense and, if possible, Amazon CPM ads and any other ad networks I can find. The domain is $300. The content would be $150. There's $550 left in case anything else is needed, such as some development work or whatever. I can tell by month 3 if the site should get any dev work. Because the site's already indexed, new pages should be indexed fast. It should also rank fast too. IMO, after I get the writing, this should be a weekend project. The only remaining question is: how should the site be organized. At 16,000 or more pages, that's a lot. The target site lists the top 200 pages on the homepage and then organizes everything by an A-Z index. IMO, a homepage that shows all posts works -- the pagination would count as a long page and all posts would get a link from the paginated homepage... but that's quite messy. I'm guessing categorizing the $Nouns from A-Z would be good -- it'll let the user search for $Nouns easier. I'll also have to scrape and insert photos of $Nouns into these pages to make them somewhat useful -- "can you smoke cinnamon?" with no photos of cinnamon would be a lackluster page. Haha, I'm also thinking about a "smokability bar" where users can rate if its a good idea or not to smoke $Noun. It should be easy to pull off and it'll add to the hilarity.
